desert garden with flowering plants
Backyard desert landscape with low-water plants.

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

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.

Embracing the Desert Heat: Landscaping with Desert-Adapted Plants

Surviving the Summer Scorch with Desert Adapted Plants

Let’s face it…summer can be brutal.

I tend to spend as little time outdoors as possible when temperatures soar above normal ranges. It’s times like this that I praise the inventor of air-conditioning.

While we can escape record-breaking temperatures, our heat-stressed plants can’t.

Beauty in the Heat: Desert-Adapted Plant Landscaping

However, you can create a landscape filled that thrives in the heat by using native or desert-adapted plants. And you know what? Most are very pretty!

Last weekend, I saw a great illustration of this…

Hospital vs. Church Landscaping: Lessons in Adaptation

Our church recently opened up a new campus, filled with new plants, but many of them were struggling to survive the intense heat, even if irrigated properly. Many were planted native to more tropical climates.

After church, my husband and I headed out to the hospital to visit a loved one. The hospital had just undergone a renovation and brand-new landscape areas surrounded the entrance.

I stopped to take a photo of one of the areas that were doing very well so I could share it with you. Full disclosure: if you hang out with me, be prepared for sudden stops to take pictures of plants.

The Secret to Thriving Landscapes

There were two main reasons that the landscape by the hospital was doing better than the one by the church:

  1. The plants by the hospital were better adapted to hot summers – desert marigold (Baileya multiradiata), gold lantana (Lantana ‘New Gold’), and Mexican fence post cactus (Pachycereus marginatus).
  2. Additionally, these plants had been installed three months earlier than the ones at the church. Yes, plants can technically be added any time of year BUT there are times that should be avoided if at all possible – specifically May and June.

Heat-Resilient Gardening

Sometimes you need to add new plants at the wrong time of year due to construction schedules, etc. In that case, I advise the use of shade cloth on a temporary basis for young plants through September IF you see that certain plants are struggling. This is in addition to watering them more often than existing plants in the landscape to help them establish their roots.

Use native or desert-adapted plants (those from other regions with similar weather conditions) to help your garden to be more resilient to hot, dry temperatures and they will need less help from you to beat the heat.

Stay cool friends!

Well-Designed, Natural Landscape in an Unusual Place

Standing Out in a Sea of Sameness: A Well-Designed Natural Landscape

Have you noticed that landscapes around parking lots and shopping malls look somewhat lackluster? This is often due to a combination of over-pruning, over-planting, and the wrong plant in the wrong place. 

Sadly, this is so commonplace. A beautifully designed and well-maintained landscape stands out as a shiny diamond.

A Pleasant Surprise: Native Plants and Natural Shapes

a natural landscape

My husband and I went to our local outlet mall to buy some clothes for him. I hadn’t walked more than a couple of steps when I realized that something was wrong. Well… actually right! The parking lot islands have shrubs that are spaciously planted and not pruned into round balls and cupcake shapes.

Native plants looking very nice in a Well-Designed, Natural Landscape in an Unusual Place

Most of the plants were native plants. The landscape grows together attractively and in natural shapes. This begs the question, who created a rule that plants can’t touch each other?

Colorful Desert Shrubs and Perennials

Shrubs such as Baja fairy duster (Calliandra californica), turpentine bush (Ericameria laricifolia), and chuparosa (Justicia californica) stood out. The shrubs are combined with ornamental grasses like pink muhly (Muhlenbergia capillaris)

I confess I didn’t make a very helpful shopping companion for my husband. The attractive landscaping constantly distracts me, causing me to stop frequently to take pictures.

A Shopper’s Paradise: Discovering Yellow Orchid Vines

fabulous yellow orchid vine (Callaeum macropterum)

My favorite area was where a fabulous yellow orchid vine (Callaeum macropterum) was growing up a large wall. 

Because of the wall’s large scale, people have planted at least three vines together. Yellow orchid vine deserves more frequent use in landscaping but is seldom observed.

Yellow vines in the Well-Designed, Natural Landscape

I find that it does best in morning sun or filtered shade and regular water. Its yellow flowers are lovely and form a papery seed pod that resembles a butterfly. You can learn more about this vine here. This isn’t a common vine that you’ll find at the nursery. But you can usually find them at botanical garden plant sales or your local nursery may be able to order one for you.

If you live in the greater Phoenix area, and want to see some great examples of desert natives and natural landscaping. Definitely plan a visit to the Phoenix Premium Outlets in Chandler. And who knows? You may even find some great deals at your favorite outlet stores.

From Grass to a ‘Natural’ Desert Landscape

bermuda grass

Do you have a lawn? I do. My son enjoys spending time outdoors playing football or soccer on the backyard lawn while my grandson likes to run barefoot on it.

Maintaining a lawn does take work including fertilizing it twice a year. My warm-season lawn is bermuda grass, which needs fertilizer in spring and the fall. Grass needs nutrients, like nitrogen for its health and to look its best. When it comes to choosing a type of fertilizer, I select organic fertilizers versus synthetic ones whenever possible.

Why choose an organic fertilizer rather than a synthetic fertilizer, you may ask? Their effects last longer, they come from natural (renewable) sources, they won’t kill beneficial microorganisms in the soil, and won’t harm the environment. 

My lawn needed to be fertilized not only for its health, but I was hosting a wedding in my backyard, and the grass had to look its best. I applied BioFlora 5 lb 6-10-1 Crumbles Stand Up Bag which is an organic fertilizer that is suitable for all plants in the garden, including lawns

Applying the fertilizer was easy using our spreader – you can also use a hand-spreader if that’s what you have.

Two weeks later, my lawn looked vibrant and healthy, making the perfect backdrop for my daughter’s wedding.

The grass won’t need any other fertilizer until October, just before it goes dormant. It may seem strange to fertilize just before the grass goes to sleep for the winter, but it is recommended as the grass stores up the nutrients, which enables it to green up more quickly the following spring.

A few weeks ago, I was asked by one of my editors to come up with a list of the top 10 plants that every resident of the Southwest should consider adding to their Southwestern landscape.

I must admit that the task was a bit daunting at first – not because I couldn’t think of enough plants.  The problem was that my list was much larger.

How Easy is it to Find Native Southwestern Landscape Plants at a Local Nursery?  

Agave parryi in Southwestern landscape

I had to pare my list down and decided to focus on plants that would grow in zones 7 – 10, which cover much of the desert Southwest.  In addition, they had to be low-maintenance, native, beautiful and easy to grow.

After considering all of the criteria, I still had about 20 plants.  So, I added one other criteria of my own – how easy is it to find at your local nursery?  

At the end, I had 10 plants that I was very happy with – but I could have easily added a lot more 😉  

I hope you enjoy reading through this list of 10 essential plants for the desert Southwest.    

Flourishing Amidst Adversity: 10 Resilient Plants in the Southwestern Landscape

The desert Southwest is a region of extremes, with scorching summer heat and chilling winter temperatures that challenge even the most robust flora. Yet, in the face of such harsh conditions, these native plants not only survive but thrive. Equipped with remarkable adaptations, these tenacious species call the arid landscapes of the U.S. Southwest their home.

Enduring the relentless dry heat and enduring the freezing winter cold, they serve as a testament to nature’s resilience. Beyond their endurance, these plants play a vital role in the ecosystem, providing nectar for birds and bees, and shelter for native bird species. Every one of these drought-resistant plants contributes to the desert’s beauty.

Embracing the Sun: Essential Care Tips for Desert Native Plants

To cultivate a thriving desert garden, sunlight is key. Native desert plants require full sun, although some tolerate partial shade for a portion of the day. Optimal growth is achieved through deep, infrequent watering and well-drained soil.

Allow water to penetrate down to 1½ to 2 feet deep, ensuring the soil dries out before rewatering. For irrigation efficiency, drip systems are recommended. While new plants need more water until established, these desert natives rarely require additional fertilization.

Tour of Sustainable Southwestern Landscape: Part 1

sustainable landscape

When most people think of a ‘sustainable landscape’, they view one that is boring, filled with few plants which is why they are often surprised to see how beautiful they are.

Over the past couple of weeks, we have talked about small steps that you can take toward a more sustainable landscape and today, we will finish up our series with a few more steps you can take in your own garden.

Re-think what you plant in pots.

Leaf lettuce, garlic, parsley growing along side petunias

Leaf lettuce, garlic, parsley growing along side petunias.

If you are like most people, you have a few pots that you fill with flowering annuals, which you fertilize on a semi-regular basis.

But, how about thinking outside of the box about what we add to pots.

For example, did you know that many vegetables do great in pots and are also attractive?  I like to grow vegetables in my pots and add a couple of annual flowers in for a little color.

A Few New Ideas for Sustainable Landscapes

While some flowering annuals can be a bit fussy (pansies, for example) – herbs are not.  They look great in pots, are on hand whenever you need a bunch of fresh herbs for cooking and they don’t need as much water and fertilizer as flowers.

Succulents make beautiful pots with their varied textures.  Because the store water inside, they do not need as much water as other container plants.

A Few New Ideas for Sustainable Landscapes

A helpful tip for planting a large container – fill the bottom third with recyclable plastic bottles.  Most plant’s won’t reach to the bottom of large containers and it is a waste of money to fill up the entire pot with expensive potting soil.  Another bonus is that it also makes your pot a bit lighter.

Use natural or recycled materials when possible.

Often, when we are adding elements to our landscape, we overlook the many things that are recycled or natural that can fill that need.

For example – did you know that you can create a ‘living’ fence made from Ocotillo canes?  It’s true! I have seen them my local nursery.

Pathway made from recycled, broken concrete

Pathway made from recycled, broken concrete.

If your landscape needs a path – instead of buying new pavers or step stones, use recycled, broken concrete.  Or use natural stone products like flagstone.

Sustainable Landscapes

It is hard to overstate how boulders can help a landscape go from ‘okay’ to ‘fabulous’.

Boulders add both height and texture without needing any water or pruning.  In addition, boulders make plants look better when they are planted alongside.

Sustainable Landscapes

Eliminate or decrease the use of pesticides.

Our first reaction when seeing insects damage on our plants is to run for the nearest pesticide in our misguided attempt to rescue our plants.

But, did you know that most plants can handle some damage from insects without any problem?

In fact, once damaging insects take up residence in our favorite plants – soon after new bugs come along that devour the bad bugs.

If you see something is eating the leaves of your plants, you have several options that are not harmful to the environment:

– Ignore it

– Prune off the affected foliage

– Pick off the insects (or spray off with water).

– Apply an organic pesticide such as insecticidal soap or BT (Bacillus thuringiensis).

You can also help to prevent damaging insects by planting ‘companion’ plants, which bad bugs do not like.  For example, planting garlic around roses helps to keep aphids away.

A sustainable, low-maintenance landscape is not only beautiful, it can save the use of unneeded resources such as maintenance, time and money.

To date, our series on sustainable landscaping has talked about what is a sustainable landscape.  Next, we talked about what often goes wrong in the landscape that causes us to use unneeded resources.  

In our quest toward a more sustainable landscape, we started to discuss small steps that you can take towards a more sustainable garden.  In part one, we covered plant selection and what types of plants to avoid as our journey toward a sustainable landscape progresses.

Today, we will finish up our series on sustainable landscaping with additional steps you can implement in your garden right now.

Reduce over-crowded landscapes by removing excess plants.

sustainable landscaping

As you can see, there are far too many shrubs in this area, which helps to contribute to over-pruning.

To help solve this problem, simply remove the excess shrubs.  How can you tell which ones to remove?  First, find out what type of shrubs they are – in this case they are ‘Green Cloud’ Texas Sage (Leucophyllum frutescens ‘Green Cloud’).

Then use one of the resources I gave you last time to research the plant, which would tell you that this type of shrub will grow about 6 feet high and wide. So, the shrubs should be placed at least 6 feet apart.  

Using the photo above as an example, start out with the first shrub on the left, measure out to the next shrub that is at least 6 feet away.  Any shrubs between these two shrubs need to be taken out.  Repeat the process until the remaining shrubs are at least 6 feet apart.

Stop unnecessary pruning.

sustainable landscaping

These shrubs have plenty of room to grow in the landscape, yet they are pruned every couple of months.

This type of pruning is called ‘poodle’ or ‘cupcake’ pruning.

It is really quite amazing how much more work over-pruning causes and in ways you may be surprised to discover, click here to learn more. To reduce the amount of resources (green waste, water, plant replacement, and maintenance bills) wasted on unneeded pruning.

So declare your landscape a ‘poodle’ and ‘cupcake’-free zone.  Believe me, your plants will thank you for it and your plants will look much nicer.


Allow shrubs to grow to their natural size.

sustainable landscaping

When you allow enough room for plants to grow, the temptation to over-prune is greatly lessened.

Plants have a lovely shape that we frequently ruin, by making them into ‘balls’ or other unnatural shapes.  This does not only affect the health of the plant, it can also remove flowers.

Note: I am not saying that all pruning is harmful.  Pruning done properly can be beneficial for plants.

So, what if you have a landscape filled with over-pruned shrubs.  What can you do to transform them into more naturally-shaped shrubs that are more sustainable? 


The answer is relatively simple and it does involve pruning…

over-pruned shrub

This over-pruned shrub is located in my neighborhood.  I cringe whenever I walk by it while walking our dogs.

It is seldom allowed to grow any leaves before the landscapers come just about every leaf off.  Frequent over-pruning has led to old, woody growth that is unproductive.  

The solution to transforming this shrub is called rejuvenation pruning, which entails pruning the shrub all the way back to 1 1/2 feet.  In most cases, this will stimulate attractive, new growth that you can allow to grow into their natural shape.

*I mention ‘in most cases’ because there is always a chance that the shrub will not recover from this type of pruning.  However when this happens, it is usually an indicator that the shrub was already declining and would not have lived long regardless of whether it was severely pruned or not.

Below, is an example from my own garden…

sustainable landscaping

On the left, you can see a sage shrub that has been allowed to grow into its natural shape, which is more sustainable then over-pruning.  In addition, I also get a lot of beautiful flowers.

Every 3 years of so, when the branches become woody and unproductive, I prune it back severely (in spring) and within 4 – 6 weeks, it is already growing new branches filled with attractive foliage.

Water your plants deeply and infrequently.

sustainable landscaping

Would you be surprised to discover that 80% of your water bill is used outdoors?  It’s true.

Would you also be shocked to discover that most of us over-water our plants?  In fact, more plant problems are caused by over-watering then under-watering.

So, why waste water, which is a precious resource in the western United States needlessly?

While you can have a landscape filled with desert-adapted plants that need no water, after established – your plants will look better if given some supplemental water.

For my own landscape – I water my shrubs and perennials once every 3 weeks in the winter months and it looks beautiful.

In the summer, I water every 7 – 10 days.  

The key is to water shrubs to a depth of 2 feet, perennials/groundcovers to 1 foot and trees to 3 feet.

So, how do you know how often to water?

There is excellent information available for the Phoenix metro area that you can access here.

For those of you who in other arid climates – check with your local extension office for watering guidelines.  

However, if that seems rather complicated, there is a new irrigation controller that does all the work for you.  All you have to do is enter your zip code, once the controller is installed and it will keep track of your local weather and water your plants only when they need it.  You can find out more about this Smart Irrigation Controller, here.

*For those of you who would like more information, I have written more extensively on landscape watering for desert gardens that you can access here.

Do you have a sustainable landscape?

One that does not require excessive amounts of fertilizer, water, pruning, gasoline or time?

Over the past week, we have been talking about what a sustainable landscape is.  We learned about the definition of sustainable landscaping and saw examples of both good and bad landscapes in the post, “What Is a Sustainable Landscape.”

In the latest post, we talked about four mistakes that people make that keep their landscape from being sustainable such as over-pruning.  If you missed it, you could see what the other three common mistakes are  – “What Keeps a Landscape From Being Sustainable?”

If your landscape falls short of being sustainable, or you want to decrease some resources that you use, there are small steps that you can start to take today toward a beautiful, sustainable landscape.

Step 1: Reduce the number of high-maintenance plants in your landscape.

hibiscus beautiful

Isn’t this hibiscus beautiful?

However, if you are growing it in the desert southwest with our nutrient-poor soils and dry, hot climate – it takes a lot of fertilizer and water to keep it looking like this.  

In addition to needing fertilizer and more water, pests can often bother hibiscus, which is then treated with insecticides as well.

Sustainable Landscape

As popular as queen palms are, they are not well-adapted to our climate and soils.  So, frequent applications of palm fertilizer are required throughout the warm months of the year.

Sustainable Landscape

Can you tell what this plant is?

It is a severely chlorotic and unhappy gardenia.  These plants like acidic soil.  The problem is, we have alkaline soil in the southwest. 

Sustainable Landscape

Okay, before I get any rose-lovers angry at me – let me first say that I love roses and have three of them in my backyard garden.

Yes, roses do need extra attention in the form of fertilizer, water, and pest control.  But if you look back at step #1, you will notice that it says to decrease the number of high-maintenance plants.

Yes, our gardens would be more sustainable if we had none of these plants that require extra resources in our landscapes, but gardening is also about pleasure and enjoyment.  So, including a few of your favorite higher-maintenance plants doesn’t make you a bad person 😉

**I use an organic fertilizer for my roses and plant garlic around my rose bushes that help keep aphids away.  

Step 2: Reduce the amount of frost-tender plants.

Frost-damaged natal plum.

While many frost-tender plants such as bougainvillea, lantana, natal plum (Carissa microcarpa), yellow bells (Tecoma stans) and others thrive in our climate spring through fall – once temperatures dip below freezing, they suffer frost damage.

Once spring rolls around, homeowners and landscapers are hard at work pruning back all of the brown, crispy foliage which contributes to green waste (branches, etc.) that often ends up in landfills.  Also, gasoline is a resource used to deliver our garden debris to the landfill and powers some of our pruning equipment.

frost-damaged plants

Before we leave the subject of reducing the amount of frost-damaged plants – let me say a word about ficus trees.

They are lush, green and beautiful.  However, they are also sensitive to temps below freezing.  

During a mild winter, your ficus may not suffer any frost damage.  But, every few years, we do go through a cold spell when temperatures dip into the 20’s, and severe damage is done to the outer leaves and branches.

Homeowners are then faced with severely pruning back their ficus trees, which causes them to look somewhat ugly while they slowly recover.

Step 3: Use plants adapted for your climate.

This is perhaps the most obvious step toward a more sustainable landscape.

In the desert southwest, plants that are adapted to our hot, arid climate are crucial to a sustainable landscape.

Arid-adapted plants have a special characteristic that helps them to thrive in the blistering heat of summer while not requiring large amounts of water.

Notice the flowering of ‘Rio Bravo’ sage (Leucophyllum langmaniae ‘Rio Bravo’), pictured above.  Do you see the tiny hairs that cover the flowers?  There are even smaller hairs that cover the leaves, which give them a grayish color.

These tiny hairs help to reduce the amount of water lost to the atmosphere (evaporation) and also reflect the sun’s rays away from the plant.

Palo Blanco (Acacia willardiana) tree

This Palo Blanco (Acacia willardiana) tree has different characteristics that helps it to survive our desert climate.  

It has tiny leaflets, which limit the amount of water lost to evaporation.  But, it also goes even further – in times of drought, the tiny leaflets will fall off, which further decreases the amount of water lost to the atmosphere.  This type of trait is known as ‘drought deciduous.’

Succulent plants

Succulent plants such as cacti and agave handle arid regions by storing water inside.

Step 4: Research plants before purchasing.

Sustainable Landscape

Have you ever been tempted by a beautiful, flowering plant and not knowing anything else about it? If you have, you aren’t alone.

But, you will be saving yourself a lot of time, money and more if you do a little research before you buy a new plant.

When deciding what type of plant to add to your landscape, ask yourself the following questions:

– How large will the plant grow?

– What exposure does it need – full sun, filtered shade or full shade?

– Is the plant drought-tolerant, or does it require large amounts of water?

– Will it require regular applications of fertilizer?

– Is it prone to pests or other problems?

Those are basic questions that you should know before you even dig a hole for a new plant.

So, if you don’t have a bookcase or two filled with plant books (like I do) – where can you go to research plants?

Here are a few online resources to get you started researching plants for the southwestern climate:

Arizona Municipal Water User’s Association Landscape Plants

Mountain States Wholesale Nursery

The Desert Botanical Garden ‘Desert Garden Guides

I do have a few favorite books that are invaluable as well…

I like to use plants that I call ‘fuss free’.  They are all drought-tolerant, most are cold-hardy in zone 9a, don’t require supplemental fertilizer, need pruning once a year or less and most of all – they are beautiful.

I hope you have found these first steps toward a more sustainable landscape helpful.

Next time, we will discuss how to care for your plants and avoid unnecessary maintenance. In most cases, if you choose the arid-adapted plants, they will need very little maintenance.

Have you ever wondered how sustainable your landscape is?

What Keeps a Landscape From Being Sustainable?

Earlier this week, we began our series of posts on sustainable landscaping and talked about what a sustainable landscape is.  You can find the first post here.

Most of us like the idea of having an attractive landscape without wasting resources such as fertilizer, excessive pruning and water, time and gasoline unnecessarily.  But, oftentimes we do things in our gardens that create the need for additional resources.

Today, we will look at one of the major problems that I see which often goes wrong and prevents people from having sustainable landscapes.

MISTAKE #1:

Most people fail to take into consideration how large their new plants will grow.

For example:

Leucophyllum frutescens 'Green Cloud'

This young ‘Green Cloud’ Texas sage (Leucophyllum frutescens ‘Green Cloud’) measures roughly 1 foot high and wide.

But, just a few years after planting, it does grow quite a bit…  

'Rio Bravo'

This ‘Rio Bravo’ sage (Leucophyllum langmaniae ‘Rio Bravo’), which is similar in size to ‘Green Cloud’ Texas sage reaches sizes up to 8 feet tall and wide.

It’s hard to believe that such a small shrub can grow so much in just a few years time.

sustainable landscape

This trailing rosemary was initially quite small when planted next to this boulder.  However, the homeowner did not allow for the fact that the rosemary would grow and eventually ‘swallow’ the boulder.

This small ficus tree looks rather innocent, doesn’t it?  But, it is harboring a secret…

sustainable landscape

It will grow absolutely huge!

This ficus tree absolutely dwarfs this house.

The mistake of not allowing for the mature size of plants when planting, leads to…

MISTAKE #2:

Over-planting.

sustainable landscape

At first glance, there appears to be nothing wrong with this landscape area.  There are some larger dwarf oleanders in the background and nine young Texas sage shrubs.

But, do you think that the Texas sage shrubs will fit in this area once they start to grow toward their mature size of 6 – 8 feet?

I don’t think so.

Over-planting occurs when people don’t allow for the mature size of the plants.  Of course, new plants look rather small and somewhat straggly once first planted, which often leads to over-planting to make the new area look more attractive.

That is what happened to this area below…

sustainable landscape

Would you believe that the shrubs planted above are actually the same as those shown below?

sustainable landscape

It’s true.  The only difference is that in this space, the mature size of the shrubs was taken into account, so there was no over-planting taking place.

Think about how much less money and maintenance this area uses compared to the previous area?  There are fewer plants, less maintenance and it looks much nicer!

Mistakes #1 and 2 lead us to…

MISTAKE #3:

Excessive pruning.

sustainable landscape

So, what do you think people do if their plants are planted to closely together – they prune them…a lot!

Drive-thru’s are places that you can usually find over-planted landscapes.  The one above is filled with 2/3’s more plant material then is needed.

The over-pruned shrubs in the forefront are actually Valentine (Eremophila maculata ‘Valentine’) shrubs, which look much more attractive when not over-pruned.

sustainable landscape

There are 3 Valentine shrubs in the photo above that are allowed to grow to their natural shape after their annual pruning in May.

These silver sage shrubs at our local Costco store have also been over-pruned due to the fact that they were planted too closely together.

Over-pruning often leads to artistic expressions…

sage shrubs

Words fail me attempting to describe the pruning  of these sage shrubs.

Here are some interesting facts about over-pruning that you may be surprised to hear.

Over-pruning…

– makes plants grow faster (as they attempt to re-grow the leaves lost)

-creates more maintenance (faster growing plants tend to be pruned more often)

– uses more water (in their attempt to re-grow lost leaves pruned away).

– creates green waste (branches/leaves head to the landfill)

– leads to unhealthy plants (from the stresses of too much pruning).- wastes time used for un-needed pruning.

Have you ever seen the inside of shrubs that have been excessively pruned for years?

I warn you, it isn’t pretty…

Not too pretty, is it?

Over time, flowering shrubs that have been excessively sheared, can develop large dead areas and eventually decline.  This leads to old shrubs being removed and a new ones put in.

MISTAKE #4

Growing plants that aren’t adapted to your climate.

sustainable landscape

Plants that are not well-adapted to your local climate require excessive resources such as extra water, fertilizer and other maintenance.

Queen palms (Syagrus romanzoffianum) are just one example of a plant that often struggles in our southwestern, desert climate.  No matter what we do, they will never look as nice as the queen palms growing in more tropical climates.

The lesson to be learned from this is that not planning for the mature plant size, over-planting, over-pruning and wrong plant selection uses up a lot of resources.

1. Excessive amounts of water are used due to over-planting, over-pruning and for plants not well-adapted to our arid climate.

2. Money is wasted on buying more plants then are needed.

3. The costs of maintenance used for excessive planting and pruning include another resource – gasoline.

4. Declining health of plants that have not been pruned properly or those ill-suited for our dry, hot climate.

************************

So how does your landscape compare with examples, above?

If you see some similarities – don’t worry.  There are things that you can do to decrease the amount of resources that go into maintaining your landscape.

My goal is to help you toward not only a more sustainable landscape, but one that is also beautiful and attractive.

In my next post, we will start to talk about
