Did you know that what you plant today has short-term and long-term benefits? It’s true. As water resources become even more precious, planting wisely is more important than ever. You will enjoy the immediate effects of lowering your outdoor water use while enjoying the knowledge that you are creating a sustainable outdoor space for the future.

Another benefit is that low-water plants are beautiful and increase your outdoor enjoyment.

So, let’s discuss four ways of “planting ahead” to ensure that your desert landscape is resilient for years to come.

Plant More Shade

The benefits of shade in the garden cannot be overstated; trees are a great way to achieve that. Trees offer a welcome respite from the hot desert sun while adding beauty to the landscape. Additionally, trees reduce outdoor temperatures underneath their branches, and when placed on the west, east, or south side of your home, will save money on energy bills.

Native and desert-adapted trees don’t use much water, and plants grown under the branches of trees use less water than those planted in full sun.

Look at the areas around your home and see if there are areas where shade be added. If you have a narrow space where trees won’t fit, consider using tall shrubs such as hop bush (Dodonaea viscosa) to provide shade.

Plant More Color

People are naturally drawn to color, and you can improve your home’s curb appeal by adding colorful plants. Desert dwellers have many flowering plants to choose from – from groundcovers, shrubs, and vines. Additionally, we have a year-round growing climate so you can always have something in bloom outdoors.

To maximize the color impact of plants, group the same plants together in threes or fives instead of just one. Place colorful plants in high-visibility areas such as against a wall, the corners of your property, and near the front entry where they are sure to be seen.

Avoid the biggest color mistake and stop excessively pruning flowering plants into unnatural shapes. Most flowering shrubs need pruning once a year or less.

Vibrant pots filled with Baja fairy duster (Calliandra californica), ‘Blue Bells’ emu (Eremophila hygrophana), Mexican honeysuckle (Justicia spicigera), and mealy cup sage (Salvia farinacea) attract pollinators under the filtered shade of a palo verde tree.

Plant More Wildlife

Our gardens can help benefit wildlife by providing food and shelter. A bonus is that you get to view them up close! The easiest way to invite wildlife such as birds, bees, and butterflies is to incorporate plants they are attracted to.

Trees, shrubs, and even cacti can provide shelter, while the blooms from certain plants will provide nectar and seeds. One easy way to encourage pollinators to visit your garden is to replace thirsty flowering annuals in containers and plant flowering shrubs instead. The shrubs will use less water while still providing you with color. 

Baja fairy duster (Calliandra californica) is one of my favorite choices for attracting pollinators such as butterflies, hummingbirds, and larger bird species are attracted to the seeds.

 

colorful ground covers
A front yard that had the lawn removed. Flowering groundcovers such as gopher plant (Euphorbia rigida), trailing lantana (Lantana montevidensis), and angelita daisy (Tetraneuris acaulis) add beauty for much less water.

Plant More Water Saving

Plants don’t use the same amount of water – some need more, while others do fine receiving less while still looking great. You don’t need a yard filled with thirsty plants because many beautiful plants use less water (and I’m not just speaking of cacti and succulents). 

Switch out high-water-use plants and replace them with those that need less water. Groundcovers are an excellent substitute for a lawn – particularly decorative ones. Many low-growing groundcovers have lush green foliage but require a fraction of the water that a lawn does. While they can’t be walked upon, they make a beautiful addition to the landscape, and many add a colorful element and provide a food source for pollinators. Even better, they require very little maintenance.

Planting ahead involves strategically selecting the plants we choose for our desert landscapes. These four ideas will help you create a beautiful yet sustainable outdoor space that will save water and provide a more sustainable future.

Need help choosing the right low-water plants? I invite you to visit AMWUA:Plants or explore the plants in my award-winning book, Dry Climate Gardening, where you will find useful tools to help you implement these recommendations.

A New Year and Wonderful Possibilities

, , , , , , ,

I love winters in the desert. It’s a time when activity in the garden slows down and we can sit back and ponder what plans (if any) we have for this new year.

As I sit in my office looking outdoors at my winter garden, I see birds visiting my feeders and the stark winter beauty of my trees.

And, I am excited about what 2024 will bring – both professionally and in the landscape areas around my home.

While the colder temperatures mean less work in the garden, there are some projects that should be done in winter:

Winter Garden Tasks

  • Prune deciduous trees, if needed. This includes ash, Chinese elm, desert willow, and pistache trees.
  • Cut back roses if you haven’t already, and add new bare-root roses. Check out my Growing Roses in the Desert, online class for guidance on rose care in a hot, dry climate.
  • Be sure that you aren’t over-watering your plants. They need far less water in winter than in other times of year. Visit Water Use It Wisely for scheduling info.
  • Winter is also a good time to add new plants. This gives plants time to grow a good root system before the heat of summer arrives. I’ve added several new plants this month, including passion flower vine and tangerine crossvine.

I encourage you to take advantage of this season to enjoy the beauty of your garden with a warm cup of coffee or tea.

The outdoors is an excellent stress reliever, and I am going to take the time this year to just sit and enjoy it – imperfections and all.

How about you?

Early Morning Birding Exploration

, , , , , , , , ,

I have picked up a new hobby, which was a bit accidental – birding!

As a horticulturist, birds go along with gardening, and I’ve always enjoyed them. One of my most requested speaking topics is about gardening for birds. However, I have begun to dive deeply into the fascinating birding world.

Birding is Fun with my Family

It may surprise you that the Southwest is one of the top bird-watching destinations. I am fortunate that there is a lovely riparian preserve a few miles from my home where you can see many different species of birds.

It turns out my two sisters also enjoy birding, so the other day, we met up early to go for a morning walk and explore the birds at the Riparian Preserve at Water Ranch, in Gilbert, Arizona.

This photo is of me and my sister Jennifer, who is a year younger than me. She is also the invaluable assistant to ‘AZ Plant Lady’ who would be nothing without her 🙂

It was a cold morning, but the birds were out, and so were we ready with our binoculars. The trails are level and circle eight different ponds. Trees and shrubs are allowed to grow in their natural shapes, providing plenty of shelter for birds, but we could see many in the trees and on the water.

We spotted the red of a Northern cardinal. I am always excited when I see one of these colorful birds because we don’t get many of them.

His mate was close by. Northern cardinals don’t migrate but stay in place all year.

We also spotted the orange breast of a robin but didn’t get a good photo of it.

An Anna’s hummingbird perched on the leafless branch of a shrub. His feathers are puffed up to help keep him warm. I am so grateful that we enjoy hummingbirds in our region all year. While we walked, we could hear hummingbirds everywhere.

From the tiny to the large, Canada geese gently honked as they saw us approach, hoping for food. We saw many other types of water birds, including pelicans – imagine pelicans in the desert! They leave in the summer.

A tiny verdin was busy eating tiny insects in a palo verde branch. I have a nesting pair of verdin in my own garden, and I love to watch their antics as they perch on my flowering shrubs. Verdins are just a little larger than hummingbirds.   

A roadrunner was out for a morning walk, but earlier, we spotted it in a tree. Roadrunners are fun to watch, especially when they catch small lizards.

A curved bill thrasher was enjoying the morning with his mate. I have a pair that visits my bird feeder at home. I like their golden eyes.

My youngest sister, Grace, is a professional photographer and took all these amazing photos. She kindly let me share them with you! You can see more of her stunning photos on her Instagram account, The Reluctant Birder.

I can hardly wait for another ‘sister’ birding walk!

I encourage you to observe the birds who visit your garden or go to some natural areas to view our feathered friends.

Mishaps in the Garden

Mishaps in the Garden: Dealing with Unexpected Plant Problems

The Unpredictable Nature of Gardening

In a perfect world, everything runs smoothly with no unexpected problems, and while you may not know what the future holds, it’s always positive.

But, you know that isn’t how life works and this is certainly true in the desert garden.

Seeking Answers for Garden Mishaps

The other day, I was walking through my back garden after returning from summer vacation, and what I noticed didn’t make me happy.

Several plants around my flagstone seating area were dead or barely alive. In fact, I need to replace at least ten plants in this area.

This lead me to wonder why I suffered these mishaps in my garden. The plants are about three-years-old and were doing fine earlier this year.

In the picture above, you can see a part of this area as it looked last fall. As you can see, all the plants are happy and thriving. Sadly, now some of them aren’t – especially the blackfoot daisy and shrubby germander.

So why did some die this summer?

The Culprit: Tree Branch Mishap

Sometimes, the reason a plant dies isn’t readily apparent, but in my case, I knew what the answer was.

Back in June, a large branch from my palo verde tree broke off from being too heavy. Normally, my trees are well-maintained by a certified arborist company. However, due to the labor shortages prevalent post-Covid, most arborists are struggling with insufficient employee numbers.

The Impact of a Lost Shade Provider due to Mishaps in the Garden

So, my tree pruning, which normally takes place in March was postponed until July. As a result, the branch became too laden with new foliage and branches and broke off.

This particular branch shaded the seating area and a large number of plants around it. All of the plants in this area can handle full sun with no problem as long as the plants receive consistent water. However, they were accustomed to the filtered shade offered by the tree. So, when the branch fell, they were exposed to the harsh desert sun without having a chance to adjust to it over several weeks.

Embracing Change in Your Garden

Mishaps like this are part of living with nature and it’s why there are no ‘perfect’ gardens. If you strive for a perfect garden, you are likely to experience disappointment now and then. Mishaps in the garden are common.

In my instance, I am making a list of replacement plants and may try something different in place of the blackfoot daisy – I am not sure what yet.

Unexpected problems like this are often an opportunity to try new plants. Fall is right around the corner, which is the best time of year to add new plants, so I will wait until then to get my new ones in.

I hope that your garden is weathering the summer heat nicely, but if it isn’t, don’t be afraid to try something new this fall!

Avoiding Storm Damage – Desert Museum Palo Verde Trees

, , , , , , ,

Exploring the Beauty of the Desert Museum Palo Verde

Lovely flowering Desert Museum Palo Verde Tree

‘Desert Museum’ Palo Verde Trees

The Desert Museum Palo Verde (Parkinsonia ‘Desert Museum’), a beloved tree in arid climates, graces numerous residential, commercial, and community landscapes. Its striking medium-green trunk, feathery foliage, and golden late spring flowers contribute to its widespread popularity. While wind damage can be a concern, proper care and selection can ensure these trees thrive.

Avoiding Storm Damage of the Palo Verde Tree

These wonderful trees stand as a captivating addition to arid landscapes. Its medium-green trunk, delicate foliage, and vibrant late-spring blooms make it a cherished choice for many. However, understanding and addressing potential wind damage is crucial for their successful growth.

Understanding Wind Damage Concerns

One common hesitation in planting palo verde trees is their perceived susceptibility to wind damage. However, most issues arise from improper maintenance, unsuitable locations, or the selection of the wrong tree type within the Palo Verde family.

Personal Success with Desert Museum Palo Verde

I have three of these Palo Verdes around my house. They range in age from 10 to 20 years old. In all that time, I have not lost a single one. While minor branch breakage occurred at times, these resilient trees quickly recovered, showcasing the hardiness of this species.

So, how can you enjoy the beauty of this tree while lessening the danger of wind damage? As a retired certified arborist, I’m here to tell you that there are definitely things you can do.

5 Strategies for Structurally Healthy ‘Desert Museum’ Palo Verdes Trees

1. Water deeply to a depth of 3 feet.

Deep roots are key to the stability of a tree and also decrease the chance of uplifting roots. Apply water toward the outer reaches of the branches where the roots are concentrated. As a tree grows, its roots move outward, so move your drip emitters or hose as needed.

Be sure to plant in an area where there is adequate area for root growth. Parking lot islands and narrow areas don’t allow enough room for roots to anchor the tree.

2. Irrigate less frequently to avoid your tree growing too fast.

This is a big cause of wind damage with palo verde trees. It’s important to remember that they are desert trees and don’t need as much water as other plants in the landscape. But, people often overwater their desert trees, which causes them to grow too quickly. This causes the formation of weak wood because they haven’t had the time to grow strong trunks and branches. In the photo above, notice how thin the multiple trunks are.

Established native desert trees, that have been in the ground for at least 3 years, can follow these general guidelines – water 1 to 2X a month in spring/fall, 2 to 3X a month in summer, and monthly in winter. These guidelines are for our current drought situation but can be modified as needed.

3. Prune your tree correctly.

There are examples of awful pruning. One common one is known as ‘lion-tailing’ which is when trees have been over-pruned so the majority of the tree is devoid of branches except for the very top. This pruning deprives the branches of foliage needed to produce energy for the tree and to increase tree strength. It also increases the amount of overhanging branches toward the top making the tree more likely to fall.

Many landscapers don’t know the right way to prune trees and can inadvertently cause harm to your tree. I highly recommend enlisting the services of a certified arborist to prune your tree correctly.

4. Select a multi-trunk form of Palo Verde instead of one growing on a single trunk.

Desert trees naturally in a multiple trunk form, which distributes the weight of the upper branches. Palo Verde trees that have been trained to grow on a single trunk, are under more stress from the wind with their heavy top half. The majority that you see fallen have been trained into a single-trunk tree.

5. ‘Desert Museum’ Palo Verde trees generally need pruning at least once (sometimes twice) a year.

You want to be sure to prune them before the onset of monsoon season – removing any heavyweight or branches that are weakly attached.

8 Colorful Plants for the Desert Garden and Where to Find Them

, , , , , , , ,

When people think about what a desert garden looks like, what comes to mind? Perhaps, visions of lots of brown with rocks and a cactus or two? Maybe visions of mostly brown terrain with scattered rocks and a couple of cacti? But in reality, the possibilities for colorful plants for the desert garden are far greater. Picture a vibrant landscape adorned with the entire spectrum of colors – from varying hues of red, orange, and purple to shades of pink and yellow.

I’m excited to introduce you to eight vividly colorful plants flourishing within my desert garden. All are vibrantly colorful and thrive in a hot, dry climate:

Bougainvillea 'Barbara Karst' is boldly vibrant with hot pink blooms

Colorful Plants for the Desert Garden

The Best List of Colorful Plants for the Desert Garden


Bougainvillea – Bougainvillea ‘Barbara Karst’

You can’t beat Bougainvillea for the vibrant color in the garden. It thrives in our dry, hot climate and flowers off and on spring through fall. Record-breaking heat doesn’t bother it in the least. Its resilience makes it a prime candidate for covering walls and facing challenging western exposures. For maximum flowering, they need to be in full sun. For those that don’t like the messy flowers, you can opt for dwarf varieties or plant one in a large pot, which will limit its size.

Hardy to 20 degrees F. Plant in full sun for optimal flowering.

Coral Fountain Russelia equisetiformis has cascading red tubular flowers

Coral Fountain – Russelia equisetiformis

Often referred to as Firecracker Bush, this resilient plant is a colorful plant for a desert garden. It is a tropical beauty has a lovely cascading growth habit. Arching stems produce orange/red tubular flowers that delight hummingbirds. Blooming occurs spring through fall. This shrub takes a year or two before really taking off, but it’s worth the wait – I like to use them in groups of 3 to 5. It is also a good choice for adding to large containers – especially blue ones!

Cold hardy to 10 degrees F. Plant in full sun.

Firecracker Penstemon Penstemon eatoni has bold red flowers that bloom off long stems

Firecracker Penstemon – Penstemon eatoni

Winter color is often lacking in desert gardens. However, there are many colorful plants for a desert garden that offer color through winter. This western native is my favorite during winter and spring in my front garden when it burst forth with brilliant orange/red blooms. Hummingbirds really enjoy the blooms as there aren’t many other plants for them to feed on this time of year. Prune off spent flowering stalks once the flowers begin to drop and you may get another flush of blooms to extend the season. It can be hard to find Firecracker Penstemon in box stores but local nurseries usually carry them.

Hardy to -20 degrees F. Plant in full sun.

Yellow Bells Tecoma stans var. stans is a lovely green shrub with bold yellow flowers

Yellow Bells – Tecoma stans var. stans

Admittedly, there are many yellow-flowering plants in the desert, but this one is my favorite! I look forward to the gorgeous yellow blooms opening each spring in my back garden. Yellow bells bloom spring through fall,and hummingbirds are attracted to their flowers. They are fast growers and have lovely, lush green foliage. To keep them looking their best, prune them back severely to 1-2 feet tall once the threat of frost has passed in spring. There are several notable varieties of Yellow Bells in shades of orange including ‘Crimson Flare’ and ‘Sparky’.

Hardy to 10 degrees F. Plant in full sun to filtered sun.

Shrubby Germander Teucrium fruticans 'Azurea' is a Mediterranean shrub with blue-purple flowers

Shrubby Germander – Teucrium fruticans ‘Azurea’

Photos don’t do this Mediterranean native justice. When viewed in person, people are immediately transfixed by the light-blue flowers (they appear more purple in photos), which appear in spring. I have several scattered throughout my back garden, and for me, they bloom throughout winter too! Using plants with silver-gray foliage near those with darker green leaves is a great way to add interest to the landscape, even when not in flower. I dearly love this shrub for its colorful winter/spring blooms in my desert garden.

Hardy to 10 degrees F. Plant in filtered sun.

Purple Lilac Vine Hardenbergia violaceae is a great desert plant that has lovely lilac-like blooms

Purple Lilac Vine – Hardenbergia violaceae

Here is another winter-flowering beauty. Purple flowers cover this vine from February into early March. Believe me when I say that they are a welcome relief to the winter blahs. Bees enjoy the blooms, which resemble lilacs but aren’t fragrant. It does require a trellis or other support to grow up on. When not in bloom, its attractive foliage adds a welcome splash of green throughout the year on vertical surfaces. The Purple Lilac vine is a very colorful plant for a desert garden and can be found in nurseries in fall and winter, during its flowering season.

Hardy to 20-25 degrees F. Plant in full to the filtered sun but avoid west-facing exposures.

'Rio Bravo' Texas Sage Leucophyllum langmaniae 'Rio Bravo' has masses of purple flowers

‘Rio Bravo’ Texas Sage – Leucophyllum langmaniae ‘Rio Bravo’

If you love the color purple, you’ll want to include this variety of Texas Sage in your garden. Branches covered in masses of purple flowers appear off and on spring through fall, often in response to periods of increased humidity. The more humidity, the more flowers produced. There are many different types of Texas Sage and all add color to the desert garden. Now, you may not see them looking like this for the sad fact that many people prune them into unnatural shapes like balls, cupcakes, and even squares. Which would you rather have – a green ‘blob’ or a gorgeous purple beauty like this?

Hardy to 10 degrees F. Plant in full sun for maximum flowering.

Desert Willow Chilopsis linearis tree has colorful pink blooms

Desert Willow – Chilopsis linearis

I want to include a tree in our list of colorful plants for the desert garden. Desert Willow is small to medium-sized tree that are native to the Southwest. Throughout the warm season, branches with bright green leaves are covered with pink blooms. The flowers add a lovely shade of pink, which is a color not always seen in the desert. There are many newer varieties of Desert Willow – I have four different ones in my garden, but ‘Bubba’ is my favorite. This is a deciduous tree and will lose its leaves in winter. 

Hardy to -10 degrees. Plant in full sun.

SO, where can you find these plants?

Where to Buy Colorful Plants for the Desert Garden

I am often asked where is the best place to buy plants. Yes, you can head to your big box store, but they usually lack variety and are known to sell plants that don’t do well in our hot, dry climate.

My advice is to look to your local garden center and nursery for these and other plants for your garden. 

This is a Fantastic Desert Nursery

I’d like to share with you about a new nursery that is mixing things up in a good way! Four Arrows Garden is a family business, located in Vail, AZ, where you order your plants online and they deliver them to you!

The Chavez family began their business with cuttings from succulents in their backyard that soon grew to people wanting them to offer other types of plants. She explains their unique nursery, “Our business model has changed over the year to fill the need in our community. We have transformed into “not your average nursery” because of a niche market to deliver landscape plants and creating an online shopping outlet for desert-adapted plants. We are different because we allow customers to shop for plants from the comfort of their homes.”

This Nursery Has Special Desert Plants

They source their plants from wholesale growers in the Phoenix and Tucson area. While their delivery area is primarily in the greater Tucson area, They can accept special requests from Phoenix area customers.

I encourage you to incorporate colorful plants within your desert garden to improve your curb appeal and your enjoyment of your outdoor space. Local nurseries are the best sources for these plants. If you are in the Tucson area, visit Four Arrows Garden’s online nursery to make your special order and they will deliver it to your door. Check them out on Facebook where Linsay keeps you updated on the latest plants available!

Lessons From a Heat-Stressed Desert Garden

, , , , , , , , , , ,
Desert Garden heat with little fuss.

Let’s face it. Hot summers are not surprising to desert dwellers. In fact, a typical desert garden with native and desert-adapted plants will weather intense heat with little fuss.

However, this summer has been one for the books and I’ve seen signs of heat-stress that I’ve never seen before. And yes, within my own garden.

I must admit that it’s been hard to see certain plants struggling in my desert garden and I know you may have similar feelings. So, why has this summer been so much more difficult than others?

Pink Trumpet Vine partially defoliated due to the heat in desert garden

Pink Trumpet Vine partially defoliated due to the heat

While it is normal to have several days above 110 degrees F., the summer of 2020 is one for the record books. We have experienced not just a couple of stretches of above-normal temps but, several long spans of infernal heat. Damage to plants is often cumulative. This means that the more days of above-average (or below-average) temperatures – the higher incidence of reaction from plants.

Take a walk outside in your garden. You will likely notice some plants that are yellowing, wilting, or have given up and died. However, you may also note that there are some that are doing well.

Why is that? Let me show you some examples from my own garden – the good AND the ugly.

Let’s start with the ugly:

New Mexican Fence Post cactus transplants desert garden

New Mexican Fence Post cactus transplants

In March, much of my backyard was renovated. This included the addition of two separate plantings of Mexican Fence Post cacti. They are located along my back wall and as you can see, one is doing very well while the other makes me cringe when I see the yellowing.

Does the yellowing cactus need more or less water? No. Many succulents yellow in response to summer heat. Of course, this very hot summer has made it more severe. So, why the difference between the two?

The one on the left gets filtered shade in the afternoon from a nearby Palo Verde tree. You can tell that the one on the right doesn’t get any shade but full afternoon sun. In a normal summer, it would be normal to see some yellowing that will return to green once temperatures cool. I am hopeful that will happen. As plants age, they tend to handle heat stress better and as these are young, the stress was especially severe.

Signs of heat stress desert garden

Signs of heat stress

In another area of my garden, I have Green Desert Spoon and Hardy Spineless Prickly Pear, which are very heat-adapted. Yet, they do show signs of mild heat-stress that I haven’t seen before. But, they will green back up in fall. Other plants that are struggling include Artichoke Agave, Gopher Plant, and Shrubby Germander.

I am thrilled that my young Desert Willow tree in this photo is thriving despite the heat. I have four others scattered throughout my landscape and all are doing just as well.

Here are some of the good:

There are still six weeks of summer heat ahead of us. So, what should we do for now?

  1. Be sure plants are receiving enough water. You may need to increase the frequency when temps are above 110 degrees.
  2. Don’t fertilize. Feeding plants simply makes them work harder to produce new growth when all they are trying to do is deal with the heat.
  3. Don’t prune away heat-damaged growth until September. While brown leaves are ugly, they are protecting the interior of the plant. Some pruning is recommended in mid-September, which I teach in my Shrub Pruning Workshop.

We don’t know if this summer will be an anomaly or the beginning of a new normal. But, instead of throwing in the towel, I invite you to do the following instead:

Take a stroll through your garden and take note of which plants are doing well and those that aren’t. If this is to be the new norm, it would be a good idea to add more of those that handle the heat well.

desert garden

I am not going to make any major changes in my own garden. Most of my plants have done just fine in past summers. I’ll replace the few plants that died but am hopeful that next summer will be one with average temperatures. If not, then I know what plants have withstood the heat best.

Before we know it, fall will be here, and I for one, can’t wait!

How Do You Choose a Plant Nursery?

, , , , , ,
locally owned plant shop

Finding the Perfect Plant Nursery

Navigating Plant Shopping Options

“Where do you recommend I go to buy plants? At a plant nursery?” This is one question that I’m often asked by desert dwellers. The choices that people have for purchasing plants range from a locally owned nursery, a nursery chain, or a big box store. So which is best? Well, that depends on the situation. So, I am going to give you my recommendations based on different factors.

Exploring the Local Nursery

local Plant Nursery

Local Nursery

Situation #1:

You have just moved into a new house and want to add some plants. The problem is you have no idea what kind of plants do well in your new region, how to care for them, or what type of exposure is best.

Answer: A Locally Owned Nursery

I would highly recommend visiting a locally owned nursery, which employs people who are knowledgeable about plants. Also, the types of plants they carry are most likely well-adapted to the growing conditions of your area as well.  

Local nurseries also sell a greater variety of plants.

The mature size of a plant often depends on what climate they are grown in.  So your local nursery professional can tell you how large the plant will become in your zone. Also, what type of exposure it needs along with watering and fertilizer requirements the plant will require.

You will pay a little more at a locally-owned nursery or a small chain. Saving money due to the excellent advice and well-adapted plants for the region is a bonus.

Consider the Big Box Store Nursery

Big Box Store Nursery

Situation #2:

You have a list of plants that you need for your garden. Best yet, you are familiar with the plants that do well where you live and how to care for them. Also, your budget for purchasing new plants is small.

Answer: The Big Box Store

When you know exactly what plants you need you are at an advantage. If you have a tight budget, you may want to check out your big box store’s nursery

Another important thing is to be familiar the plant’s needs in advance. While nursery personnel may be helpful, not all of them are knowledgeable about plants.

The biggest benefit for shopping at a big box store’s nursery is that plants are often less expensive than at your local nursery.  Many also offer an excellent plant warranty as well.

One important thing to remember about shopping at a big box store nursery is that just because you see a plant there, does not necessarily mean that it will do well in your area.  I have seen quite a few plants available in my local big box store that is sold out of season or very difficult to impossible to grow where I live.

Shop Wisely for Your Garden

So where do I shop for plants? It depends on several factors.

Parry's Penstemon from plant nursery

Parry’s Penstemon (Penstemon parryi)

For flowering annuals, I shop at the nearby big box store as it’s hard to beat their variety and amount plants available.  

When I need perennials, shrubs, succulents, or trees, you’ll find me at my favorite local nursery. They grow most of their nursery stock, so I know that it is adapted to the climate.

While traveling to areas with similar climates to mine, I take time to see if they have any specialty nurseries and take time to visit.

I do need to confess that my favorite place to find plants is not at a nursery, but at my botanical garden’s seasonal plant sale. They have hard to find plants, and I know that whatever plants I come home with will do well in my garden.

bought from plant nursery

Regardless of where you shop for your plants, I highly recommend researching plants ahead of time.

Learn how big they get, what type of maintenance they require, watering needs and how it will do where you live.  You can find most of this information easily online by doing a simple search using the plant name + where you live, which will give you links on the plant and how it does in your area.

5 Tips for Choosing Plants From the Nursery

Mesquite Trees and Crazy Branches

, , , , , , , ,

Have you ever paused in the shade of a mesquite tree (Prosopis spp.) and noticed that its branches grow every which way? 

I was reminded of this when I was visiting a client earlier this week and was advising him on how to care for his mesquite tree. I looked up and saw a cluster of branches growing up, down, sideways, and in curvy pathways.

Texas Honey Mesquite (Prosopis glandulosa)

In an ideal situation, mesquite trees resemble the shape of more traditional tree species, as shown above. However, they don’t always turn out this way.

Have you ever wondered why mesquite trees grow in such crazy ways?

The answer is quite simple – in nature, mesquites grow as large shrubs. The branches of shrubs grow in all directions, up, down, sideways, etc., and so do mesquites.  

The problem arises when we train them up as trees, and their branches don’t always behave as trees do. Because of this, mesquites that have been pruned into trees, do best being pruned by a professional, particularly when they are young and certain branches are being chosen to remain while others are pruned off.

Of course, this doesn’t always happen, and you can see the results of bad pruning practices in many places. 

I do love the shade that mesquite trees provide and I must admit that I enjoy a good chuckle when I see the unusual shapes that some mesquite trees have taken.

How about you? Have you ever seen a mesquite tree with crazy branches?

Embracing Vibrant Fall Foliage in Arid Climates

Before you lament a fall season devoid of colorful fall foliage in the arid West and Southwest regions of the U.S., here are some favorite water-wise shrubs and trees that will add glorious color in varying shades of orange, red, and burgundy to your arid autumn landscape.

Fall Foliage we enjoyed on a trip to Williamsburg, VA several years ago.

Have you ever traveled somewhere else to find colorful fall foliage? What if you could have fall color in your own landscape?

A Splash of Fall Foliage Color in the Arid Desert

Like most water-wise plants, the following do best in well-drained soil. The watering guidelines given are approximate and may need to be adjusted in response to variables such as sun exposure, soil, and climate. In general, drought-tolerant plants do best when the soil is watered deeply and then allowed to dry out before the next watering. Plant in fall or wait until spring, and enjoy fall color for years to come.

Pink Muhly (Muhlenbergia capillaris)

Pink Muhly Grass (Muhlenbergia capillaris)

Autumn Pink

In spring and summer, this ornamental grass provides an attractive backdrop with its graceful green foliage. As temperatures begin to fall and days begin to shorten, burgundy-pink plumes softly wave above the green blades, and pink muhly grass takes center stage in the garden. Its color slowly fades to a lovely wheat color in winter. Plant it in groups of three, five, or seven for the greatest effect.

Growing Conditions

Where it will grow: Hardy to 0 degrees Fahrenheit, or minus 18 degrees Celsius (USDA zones 7 to 9; find your zone)

Water requirement: Low to moderate; can survive on little water, but flowering is improved with regular summer irrigation. Water every 10 to 14 days in summer, every two weeks in spring through fall, and monthly in winter for the best flowering.

Light requirement: Full, reflected sun to filtered shade

Mature size: 3 feet tall and wide

Planting notes: Plant in well-drained soil in full sun or filtered shade; cut back to the ground in late winter; apply a slow-release fertilizer in spring.

‘Sticks on Fire’ Milk Bush (Euphorbia tirucalli ‘Sticks on Fire’)

Unexpected Bursts of Orange

Orange splashes of color come from an unexpected source with this drought-tolerant succulent. ‘Sticks on Fire’ differs from the green-colored parent plant in that it is smaller and new growth has a bright orange color. The color fades to yellow and then green in summer only to turn orange again when temperatures cool. In cooler climates it can be grown in a container and brought indoors when temperatures dip below freezing. Milk bush can easily be propagated from cuttings. Be sure to wear gloves when handling this plant, as its milky sap can irritate skin and eyes.

Growing Conditions

Where it will grow: Hardy to 30 degrees Fahrenheit, or minus 1 degree Celsius (zones 9 to 11)

Water requirement: Low; water every three weeks spring through fall and monthly in winter. In the low desert, water twice a month spring through fall.

Light requirement: Full sun to filtered shade (full sun is needed for it to develop the orange color)

Mature size: 4 to 8 feet tall and 3 to 5 feet wide

Planting notes: Plant in well-drained soil in full sun.

Chinese Pistache (Pistacia chinensis)

A Burst of Fall Foliage

Chinese pistache is for those who are looking for a tree that produces colorful fall foliage and will thrive in dry, arid climates. It is widely grown throughout the Northwest and the southern half of the United States, and is a go-to tree for reliable autumn color in the Southwest. In fall, bright green leaves give way to shades of yellow followed by orange and red, providing much-desired fall color for the drought-tolerant garden. Female trees produce berries that attract birds. This tree isn’t fussy about soil, as long as it’s well-drained, but it does need room to grow to its full size.

Growing Conditions

Where it will grow: Hardy to minus 10 degrees Fahrenheit, or minus 23 degrees Celsius (zones 6 to 9)

Water requirement: Low to moderate; water to 3 feet every 10 to 14 days in summer, every three weeks in spring through fall and monthly in winter

Light requirement: Full, reflected sun to filtered shade

Mature size: 30 to 60 feet tall and 30 to 40 feet wide

Planting notes: Plant in well-drained soil in full sun or filtered shade; prune in winter to shape.

A Blaze of Color and Fall Foliage

The allure of firebush goes beyond its stunning orange-red spring and summer blooms, which are a magnet for hummingbirds. It saves its grand finale for fall when its lush foliage transforms into a vibrant shade of red, creating a fiery spectacle. In tropical climates, this heat-loving shrub can grow into a small tree, while in drought-tolerant landscapes, it remains a manageable and colorful shrub. Although it dies back when temperatures dip into the 20s, it resurfaces in spring. In zones 7 and below, it can be grown as an annual.

Growing Conditions

Where it will grow: Hardy to 10 degrees Fahrenheit (zones 7 to 11)

Water requirement: Moderate; water 18 inches to 2 feet deep weekly in summer, every 10 to 14 days in spring through fall, and every three weeks in winter

Light requirement: Full and reflected sun to filtered shade (full sun is best for flowering)

Mature size: 4 to 5 feet tall and wide

Planting notes: Plant in well-drained soil; prune back in spring, after the danger of frost has passed.

‘Krauter Vesuvius’ Cherry Plum (Prunus cerasifera ‘Krauter Vesuvius’)

A Regal Purple Masterpiece

This plum tree species is renowned for its regal burgundy-purple foliage that graces the landscape from spring through fall. Despite being a plum tree, its fruits are typically small or nonexistent, as its true value lies in its captivating foliage. Pale pink springtime blossoms are soon followed by the emergence of dark-colored leaves. While several cherry plum varieties exist, ‘Krauter Vesuvius’ stands out as the most drought-tolerant, making it ideal for enduring hot, dry summers.

Growing Conditions

Where it will grow: Hardy to minus 20 degrees Fahrenheit (zones 5 to 9)

Water requirement: Moderate; water 2 to 3 feet every 10 to 14 days in summer, every two to three weeks in spring and fall, and monthly in winter. In the low desert, water weekly in summer and every 10 to 12 days in spring and fall.

Light requirement: Full sun to filtered shade (full sun is needed for maximum purple color)

Mature size: 15 to 20 feet tall and wide; smaller cultivars are available

Planting notes: Plant in well-drained soil; prune during winter dormancy.

Heavenly Bamboo (Nandina domestica)

A Bamboo-Like Marvel with Radiant Red Fall Foliage

Heavenly bamboo, often likened to true bamboo due to its fine-textured leaves and upright stems, unveils a delightful transformation in fall and winter. The new growth takes on a charming burgundy tint before transitioning to a bright spring and summer green. As cooler temperatures grace the landscape, the foliage transitions into enchanting shades of red. Additionally, small flowers give way to clusters of red berries in autumn. While moderately drought-tolerant, it thrives in arid regions, maintaining its vigorous growth in controlled environments.

Caution: Heavenly bamboo can become invasive in regions with abundant rainfall, especially in the eastern U.S., and all parts of this shrub are toxic.

Growing Conditions

Where it will grow: Hardy to minus 10 degrees Fahrenheit (zones 6 to 9)

Water requirement: Low to moderate; water 18 inches to 2 feet twice a month in summer, every three weeks in spring and fall, and monthly in winter. In the low desert, water weekly in summer and twice a month in spring and fall.

Light requirement: Full sun to filtered shade (prefers filtered to full shade in the low desert)

Mature size: 4 to 6 feet tall and 3 feet wide; smaller cultivars are available

Planting notes: Plant in well-drained soil; selectively prune older branches at the base in late winter or early spring.
