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.

Do you enjoy the summer heat?

I’m going record to state that I’m not a huge fan. I prefer to endure the intense heat indoors in the comfort of air-conditioning.

However, the plants in my garden don’t have that option. They are stuck outside no matter how hot it gets.

I always feel sad when I see plants struggle in the heat of summer. If I could bring them indoors to cool off I would 😉. But, let’s face it, that isn’t realistic or really what is best for plants.

For that reason, you will find the plants around my home are fairly heat-tolerant.

If you think that heat-proof plants are boring (and if I’m being honest, some are), many are attractive and beautiful.

One of my clients has a great example of an eye-catching entry that is fuss-free and shrugs off the heat of summer.

Artichoke agave (Agave parryi v. truncata), golden barrel cacti (Echinocactus grusonii), and lady’s slipper (Euphorbia lomelii), and yucca create a living sculptural landscape with their unique shapes.

As you can see, you don’t have to settle for a blah garden or one filled with heat-stressed plants. In fact, I loved this example so much that I featured it in my book, “Dry Climate Gardening” which is available for pre-order.

You know that I don’t care for fussy plants – I prefer plants that look great with little effort on my part and this succulent garden is a great example, don’t you agree?

I invite you to take a walk through your garden to see what plants may be stressed from the heat. It may be time for you to switch them out for more heat-tolerant ones.

Do you love the beauty of bougainvillea? Many of us will agree that bougainvillea is beautiful, but many homeowners hesitate to grow them for a variety of reasons. The most common that I hear is that they get too big and as a result, too messy.

Embracing Bougainvillea: Maximizing Beauty while Minimizing Hassle in Containers

While both statements are certainly true, wouldn’t it be nice to enjoy the captivating and vibrant beauty of bougainvillea in a more controlled manner? One can find great satisfaction in discovering how to strategically grow bougainvillea, harnessing its enchanting colors and delicate blooms while mitigating the challenges associated with its exuberant growth and occasional unruliness.

Thriving in Harsh Desert Summers: Consider Growing Bougainvillea

Let’s face it; summers in the desert can be brutal and bougainvillea are one of the lush green, flowering shrubs that thrive in intense heat and sun. So, why not consider adding one in a high-profile area where you can enjoy their beauty throughout the warm season?

The Advantage of Potted Bougainvillea: Small Size, Less Mess

Growing bougainvillea in pots limits their overall size, and with smaller shrubs, there is less mess. It also makes it easier to protect them from frost damage in winter by moving the container to a sheltered location, such as underneath a patio or covering them with a sheet.

Mastering Bougainvillea Growth: Container Planting Insights

Bougainvillea make excellent container plants. In fact, many gardeners who live in cold climates, only grow them in pots and move them indoors in winter. I met a gardener in Austin, Texas who treats bougainvillea like an annual plant, planting a new one every year to replace the old one lost to winter cold. Thankfully, we don’t need to do add a new one every year.

Simple Steps to Cultivating Bougainvillea in Pots

Growing bougainvillea in pots is easy to do. Select a location in full sun where it will promote the most bloom. Bougainvillea are one of the few flowering plants that can handle west-facing exposures.

Nurturing and Feeding Your Potted Bougainvillea for Optimal Growth

Provide support for them to grow upward if desired. You can also grow bougainvillea as more of a compact shrub form if you wish.

Water deeply and allow the top 2 inches to dry out before watering again. Bougainvillea does best when the soil is allowed to dry out between watering.

Apply a slow-release fertilizer in spring, after the danger of frost is passed. You’ll want to reapply fertilizer every three months until September.

Winter Care and Final Thoughts: Flourish with Potted Bougainvillea

Growing bougainvillea in pots keeps them small enough to make it feasible to cover them when freezing temperatures occur. So, if you like container gardening, consider growing bougainvillea in a pot for great success.

Discovering the Beauty of ‘Orange Jubilee’ and ‘Sparky’ Tecoma Shrubs

One of my favorite things I do as a landscape consultant is to show my clients newer plant and shrub introductions on the market.

Imagine being the first person on your block with the latest plant that all your neighbors will want to add in their landscape.  

Orange Jubilee shrub

The Allure of Tecoma x ‘Orange Jubilee’

Many of you may be familiar with the large, orange-flowering shrub Tecoma x ‘Orange Jubilee’. This popular shrub has clusters of trumpet-shaped flowers and a long bloom period. Its large size 8-12-foot height makes it a favorite for screening out a block wall or unfavorable view.

While the flowers and lush foliage are a plus, Orange Jubilee is too large for many smaller areas, which is why this newer shrub is one of my new favorites. 

Introducing ‘Sparky’ Tecoma: A New Shrub Sensation

'Sparky' Tecoma new shrub for the garden

‘Sparky’ Tecoma is a hybrid that has bi-colored flowers and is named after Arizona State University’s popular mascot due to the coloring. It was created by a horticulturist and professor at ASU.

Sparky shrub

‘Sparky’ is about half the size of ‘Orange Jubilee,’ which makes it suitable for smaller spaces. It has smaller leaves and a slightly more compact growth habit, reaching 4-5 feet tall and wide.

Both types of Tecoma have the same requirements – plant in full sun and prune away frost-damaged growth in March.  ‘Sparky’ is slightly more cold tender than ‘Orange Jubilee’.

Personal Experience: Adding Tecoma Shrubs to My Garden

I have added three of these lovely shrubs in my front garden. One along my west-facing side wall, and two that flank either side of my large front window. They add beautiful color 9 months a year.

For those of you who are U of A alumni, you can plant one and call it something else. To date, there isn’t any word of a red, white and blue hybrid yet – but, I’ll be sure to let you know if they create one 😉

I have a wonderful treat for you! This week’s blog post is from Dr. Jacqueline Soule.

Chances are that her name sounds familiar and that is because she is a noted plant expert and well-known author of several books on desert gardening.

Jacqueline grew up in Tucson and currently resides there where she enjoys growing low-maintenance plants that add beauty, which thrive in the desert.

I am fortunate to call Jacqueline my friend and we are both part of SWGardening.com I am excited to share with you her post on Germander.

Gorgeous Germander 

by Jacqueline A. Soule, Ph.D.

Special for AZ Plant Lady, 03 2020

Germander is a gorgeously green low-water ground cover that grows well in Arizona, is great for pollinators, and happens to be usable as a culinary herb.  

Greeting from another desert garden this week – that of garden writer Jacqueline Soule, who lives in Tucson (Gardening With Soule – in the Land of El Sol).  Noelle has graciously shared her space this week to allow me to introduce you to one herb for your landscaping.  

Germander Has a Long History

This handsome herb was brought to the mission gardens of Arizona in 1698 by Father Kino.  Germanders are native to the rocky hillsides of Greece and Turkey, where they get rain only in the winter.  This means they tolerate dry and hot conditions well!

Gorgeous Germander (Teucrium chamaedrys) growing in a Sedona garden.

Which One to Use?

There are around 100 species of germander!  The one most commonly used in landscaping is the wall germander (Teucrium chamaedrys).  This species has tiny, bright green, rounded leaves.  The creeping germander is the same species, but has been selected over time to be a low ground cover (Teucrium chamaedrys var. prostratum).  Both of these are available at many local nurseries (but not big box stores).

For landscaping, germander offers a gorgeous bright, forest-green.  I confess, I prefer this color in general over the blue-green of rosemary.  Even in poor soil and with little water, germander grows to form a dark green carpet, about 2 feet around per plant, the creeping germander a bare 4 to 6 inches tall.

Germaders grow well in alkaline (unamended) desert soil, in full sun to part shade situations.  Reflected summer light is tad too much for them, so not under picture windows.

Fragrant Flowers

Both germander and rosemary have many oil glands in their leaves and are fragrant plants.  But then there are the flowers!  Germander flowers are far more fragrant than rosemary.  Germander blooms are almost honey-scented, like sweet alyssum.  Like rosemary, germander are bee pollinated, by both European honey bees and by our native Arizona solitary bees, with occasional butterfly visitors.

Use In Your Landscape

Both rosemary and germander can be used in roasting potatoes or to add flavor to meat dishes.  I use either herb to scrub down the grill prior to cooking – depends on which needs pruning.  In ancient Greece, hunters would field dress their meat with germander, often found growing wild in the hills.  (It may have anti-microbial properties.)  Germander abounds on Greek hillsides because the strong oils render it unpalatable to wildlife.  I won’t promise it is rabbit proof, but those “wascally wabbits” don’t bother mine.  

Herbs that can be used to create a beautiful, low-water-using, edible, Southwest landscape are numerous.

Javelina in the Desert Garden

No matter where you live, you will see the same shrubs being used over and over again in countless landscapes. While the shrubs may be attractive, their overuse throughout neighborhoods creates a boring appearance because they are so common.

The Allure and Overuse of Oleanders

oleander shrubs in a row

In California, Nevada, and Arizona, oleanders have held a prominent spot in the landscape for years. Their popularity is due to their lush evergreen foliage, ability to withstand intense heat, and their pretty flowers.

However, their overuse in many areas makes their beauty less impactful and frankly, almost forgettable.

The Power of Unpredictability

 At a recent conference, this point was put quite succinctly by the head of horticulture for Disneyland who said,

“When things are expected (in the landscape), they become less powerful and impactful”.

His statement sums up what happens when we use the same plants over and over.

Oleanders’ Ailment: Oleander Leaf Scorch

In the case of oleanders, there is another problem.

Oleander leaf scorch

Oleanders are susceptible to a fatal disease called, oleander leaf scorch. This disease has come from California into Arizona where it is popping up in neighborhoods in Phoenix and also Lake Havasu. I have consulted with several cases affecting large, mature oleanders in Arcadia, Biltmore, and Moon Valley areas in Phoenix. 

This bacterial disease is spread by leaf-hopper insects and there is currently no known cure or control available. Infected oleanders slowly decline over 2-3 years before dying. To date, dwarf oleanders have not shown signs of the disease, only the larger forms. But, that could change sometime in the future.

Seeking a Shrub Alternative: Introducing Hop Bush 

Objectively, there’s a lot to like about oleanders; they thrive in hot, dry climates with minimal fuss, have attractive dark green foliage, and add color to the landscape when in flower. However, their overuse in the landscape makes them less impactful and coupled with their susceptibility to oleander leaf scorch, people want an alternative. 

You can learn more about this disease that affects oleanders here.

Hop Bush along a house wall

When asked for another option for the large, tall forms of oleanders, I recommend Hop Bush (Dodonaea viscosa), also known as Hopseed Bush.

Grab my FREE guide for Fuss-Free Plants that thrive in a hot, dry climate!

Hop Bush is a Versatile Landscaping Solution

This native desert shrub has attractive, evergreen foliage and a similar growth habit to oleander. They grow up to 12 feet tall or prune to a shorter height.

Hop Bush is a green shrub

Use Hop Bush in the same ways as oleanders to provide a nice green hedge or privacy screen.

Hop Bush has Elegance in Foliage

While they don’t have colorful flowers; they have lovely foliage that is only mildly poisonous as opposed to oleanders which are highly toxic. Hop bush has a lovely natural shape or prune as a formal hedge.

Share Your Experience

Have you ever seen hop bush growing in the landscape?  Your insights and experiences are invaluable – feel free to share them in the comments below.

For those who live in the western half of the United States, water has always been a precious resource. In recent years, this has become especially true during a long-term drought has made its impact felt.

As a result, many of us find ourselves looking for ways to save water. The first place you should start is your landscape as that is the largest percentage of your water consumption.

Today, I’d like to show you examples of three different low water landscape options: 

Drought Tolerant Water Saving Landscape

Option #1

Drought Tolerant – This landscape is characterized by lush green, semi-tropical flowering plants. These include bougainvillea, lantana, oleanders, and yellow bells. All these do well in hot, arid climates in zones 9 and above. While most aren’t native to the Southwest, they are considered moderately drought tolerant and suitable for those who want more a lush look for the desert garden.

For best results, deep water approximately once a week in summer and every 2 weeks in winter.

Moderately Drought Tolerant Water Saving Landscape

Option #2

Moderately Drought Tolerant – Native, flowering plants make up this type of landscape.  Plants like chuparosa, damianita, penstemon, Texas sage, and turpentine bush are examples of this.

Because these plants are native to the Southwestern region, they need infrequent watering to look their best – a good guideline is to water deeply approximately every 10 days in summer and every 3 weeks in winter.

Extremely Drought Tolerant Water Saving Landscape

Option #3

Extremely Drought Tolerant – For a landscape to exist on very little water, a collection of cacti and succulents are the way to go. Columnar cacti such as Mexican fence post, organ pipe, saguaro, and totem pole add height to the garden. Lower growing succulents like agave, candelilla, and desert milkweed can be used for mid-level interest.

Golden barrel, hedgehog cacti and mammillaria fill in smaller spaces and look great next to boulders. Once established, they do best with watering approximately every 3 weeks spring through fall.

It’s important to note that shrubs should be watered deeply to a depth of 2 ft., which promotes deep root growth, and the soil stays moister longer. Succulents do well at 12″ depth. 

**Watering guidelines can vary from region to region within the desert Southwest, so it’s wise to consult with your local city’s landscape watering guidelines.

Whichever option you select, creating an attractive water-saving landscape is within your reach that will thrive in our drought-stricken region.

Embracing White Flowering Plants

Are white flowering plants a part of your landscape design? They certainly are in mine.

Surprisingly, white flowers are often overshadowed by more vibrant shades like yellow, orange, or red. However, it’s worth noting that white flowers can play a pivotal role in enhancing your landscape by creating striking color contrasts.

In addition, white flowering plants also have a visually cooling effect in the garden, which is a welcome sight in the Southwest where summers are hot.

I’d like to share with you some of my favorite white flowers, all of which do well in the Southwestern landscape.

Bush Morning Glory (Convolvulus cneorum) White Flowering Plant

Bush Morning Glory (Convolvulus cneorum)

Bush Morning Glory (Ipomoea carnea)

Pretty white flowers with yellow centers are just one of the reasons people love Bush Morning Glory. Its silvery foliage is another great color that it adds to the landscape.

In the desert, the flowers appear for several weeks in spring before fading away. However, the silvery foliage is evergreen and will add great color contrast when planted nearby plants with dark green foliage.

Do you have an area that gets full afternoon sun and reflected heat?  Bush Morning Glory can easily handle it while looking great.

Hardy to zone 8, bush morning glory grows approximately 2 ft. tall and 4 ft. wide.  Prune back in spring, after flowering has finished by 1/2 its size.

White Gaura (Gaura lindheimeri) White Flowering Plant

White Gaura (Gaura lindheimeri)

White Gaura (Gaura lindheimeri)

A flowering perennial, white gaura, has a prominent place in my landscape. It has small flowers, shaped like small butterflies, that start out pink and turn white as they bloom.

Siskyou Pink White Flowering Plant

This lovely perennial does best in filtered sun and flowers in spring and fall. It requires little maintenance other then shearing it back in spring to 1/2 its size.

White gaura is related to the pink variety ‘Siskyou Pink’, but has a bushier appearance and grows larger – approximately 2 1/2 ft. wide and tall. This native perennial is hardy to zone 6 gardens.

White Cloud' Texas Sage (Leucophyllum frutescens 'White Cloud') White Flowering Plant

‘White Cloud’ Texas Sage (Leucophyllum frutescens ‘White Cloud’)

‘White Cloud’ Texas Sage (Leucophyllum frutescens)

While most of us are more familiar with the purple flowering Texas sage shrubs, there is a white variety that is well worth adding to your landscape.  

‘White Cloud’ Texas Sage can grow large, 6+ feet tall and wide, if given enough space. It thrives in full sun and in summer and fall, periodic flushes of white flowers cover the silvery green foliage.

Avoid the temptation to excessively prune this shrub, which decreases the flowering and is not healthy for this type of shrub.  Hardy to zone 7, this shrub looks great when used as an informal hedge or against a wall.

Hedge trimmers aren’t needed for pruning Texas sage. My Corona Compound Loppers are what I’ve used to prune mine for over 10 years with some hand pruning as needed for wayward branches.

For guidelines on how to (or how NOT to) prune flowering shrubs, click here.

Texas Olive (Cordia boissieri) White Flowering Plant

Texas Olive (Cordia boissieri)

Texas Olive (Cordia boissieri)

This Texas native is a huge favorite of mine – Texas olive is a large shrub or small tree, depending on how you prune it. It has dark green, leathery leaves, and beautiful white flowers, which appear spring through fall on evergreen foliage.

Whenever I see this shrub, I always take a moment to admire its beauty, since it isn’t used often in the landscape – but it should be!

Small fruit, resembling an olive is produced, which are edible. They thrive in full sun. Allow plenty of room for it to grow as it gets 25 ft. tall and wide. Hardy to zone 9, the only drawback of this white-flowering beauty is that it can be a little messy, so keep away from swimming pools.

All of these white flowering plants are drought tolerant and do well in hot, arid climates.  

Do you grow any of these in your garden? Which is your favorite?

As beautiful as these plants are, I have more to show you next time in Part 2 next week!

Exploring Unconventional Container Plants

What type of plants comes to mind when you are planning what to plant in your containers?

I’m willing to bet that purple hopbush (Dodonaea viscosa ‘Purpurea’) and bush morning glory (Convolvulus cneorum) probably weren’t the first plants that came to mind.

Thinking Beyond the Blooms

Admittedly, I tend to think of using plants known for their flowers or succulents in my containers.  That is until a trip to California that I took this past April.

A Visit to Cornerstone Sonoma

In the picturesque Napa Valley region of northern California, sits Cornerstone Sonoma, which describes itself as “a wine country marketplace featuring a collection of world-class shopping, boutique wine rooms, artisanal foods, art-inspired gardens.”

Believe me; it is all that and more.

Amidst all its offerings, it was the unconventional container plantings that captured my attention.

Unusual Choices in Container Plants

Purple hopbush (Dodonaea viscosa ‘Purpurea’), shrubby germander (Teucrium fruiticans), and violas.

Intriguingly, I discovered square steel containers filled with plants celebrated for their foliage, a departure from the typical container plantings I was accustomed to.

These unique designs were creative and beautiful.

The Appeal of Foliage-Focused Container Plantings

There were quite a few things about this type of container planting that appealed to me.

One, it is low-maintenance – no deadheading required.  Just some light pruning 2 – 3 times a year, to control their size. Second, the plants are all drought tolerant (with the exception of the violas). Lastly, I like seeing new ways of doing things and using plants prized for their foliage in containers is something we don’t see too often.  

Replicating the Concept with Container Plants at Home

Fast forward a few months, and I decided to rethink what to add to the large, blue planter by my front entry.  So, I thought, why not try the same arrangement?

Smaller but Promising

container plants

Granted, the plants are smaller than those I saw in California, but given a few months, they should grow in nicely.

As you can see my new plants are rather mall, however, the purple hopbush will grow taller and its evergreen foliage will add shades of purple and green to this space. Furthermore, this shrub is one of those highly-prized plants that do well in both sun and filtered shade.

Embracing Foliage Diversity

The silvery-gray foliage of bush morning glory creates a great color contrast with the darker greens of the other plants. While it may not flower much in this semi-shady corner, I want it for its silvery foliage.

Adding Greenery to the Mix

In addition, I want to use a plant that has bright green foliage, so I have a single foxtail asparagus fern (Asparagus densiflorus Myers), which will thrive in this semi-shady exposure. 

Maintenance will be relatively simple with periodic pruning to keep wayward branches in check. Fertilizing in spring and late summer with a slow-release fertilizer such as Osmocote will be all that’s needed to keep my container plants happy.

Do you have any plants with attractive foliage that you would use in containers?

Preparing Your Garden for a Heatwave: 5 Essential Tips

Have you ever wondered how your plants fare in the scorching heat of summer? Is your garden equipped to withstand the punishing temperatures that a heatwave can bring, whether you reside in the arid desert Southwest or more temperate regions? In this guide, we’ll explore how to create a heatproof garden that thrives even during the hottest days of summer.

What do your plants look like in the middle of summer?  Do they thrive despite the hot temperatures?  

Or do they look more like this?

Heatproof Gardening tips

Assessing Your Garden’s Heat Tolerance

Before we dive into our tips for heatproofing your garden, it’s crucial to understand how to recognize the signs of heat stress in your plants. During the hottest part of the day, take a stroll through your garden and keep an eye out for wilting leaves, as well as leaves turning yellow or brown – all telltale signs of heat stress.

5 Key Strategies to Heatproof Your Garden

Here are five essential strategies to help your garden not only survive but thrive in the face of scorching summer temperatures:

1. Embrace Native and Climate-Adapted Plants

Heatproof Gardening tips

Selecting native or climate-adapted plants is a foundational step in creating an attractive, low-maintenance landscape that remains beautiful year-round. These plants possess unique characteristics that enable them to withstand local climate conditions, including extreme summer heat. Learn how plants like Langman’s Sage and Mexican Honeysuckle adapt to thrive in the heat.

All too often, we find ourselves with landscapes filled with plants. These plants often have large leaves and struggle to survive the hot, summer months.  This results in unattractive plants that we work hard to help sustain them until cooler temperatures arrive. Usually, these plants are best meant to grow in climates with less extreme heat.

Plants Adapt to Change

Langman's Sage (Leucophyllum langmaniae)

Langman’s Sage (Leucophyllum langmaniae)

Let’s look at an example of an adaptation that this Langman’s sage. The adaptation enables it to handle full sun and 110+ temperatures without undue stress.

Notice that the flowers have small hairs.  So do the leaves, giving them a slightly grayish cast.  These tiny hairs help to reflect the sun’s rays, which lowers the temperature of the leaves and flowers.

Mexican Honeysuckle (Justicia spicigera) and Shrubby Germander 'Azurea' (Teucrium fruticans 'Azurea')

Mexican Honeysuckle (Justicia spicigera) and Shrubby Germander ‘Azurea’ (Teucrium fruticans ‘Azurea’)

Small Leaves Help

Another way that plants have to handle the heat is by having small leaves. This limits the amount of water lost, which helps them to deal with hot, dry temperatures.

Here in the desert Southwest, there are many native plants that are used. There are also plants from Australia and other arid regions, which have similar climates.

2. Harness the Power of Shade

Heatproof Gardening tips

Introducing shade into your garden offers respite from the relentless sun, benefiting both plants and your home’s overall cooling. Discover how to provide just the right amount of shade by strategically planting trees that offer filtered shade. This allows enough sunlight for other plants to flourish.

3. Master the Art of Deep and Infrequent Watering

Heatproof Gardening tips

Plants need water to survive, and not surprisingly, they need the most in the summer.  However, we often water them too often and shallowly for it to do much good.

Shallow watering keeps roots close to the surface of the soil. There the soil temperatures are hot and the water dries up quickly.

Deep Watering is the Rule

Water is essential for your plants, especially during summer, but not all watering methods are created equal. Learn why deep watering, encouraging deep root growth, is far more effective than shallow watering. Discover how to gauge the depth of your watering and why early morning is the best time to hydrate your plants.

“Plants that are watered deeply and infrequently are better able to withstand the heat.”

Shrubs should be watered to a depth of 2 feet and perennials and groundcovers to 18 inches.  You can determine how deeply you are watering by inserting a piece of rebar down into the soil (right after you have finished watering) to see how long you need to irrigate.  On average, 2 hours is the length of time to irrigate to the desired depth.  

An Online Course to Help You Understand Desert Garden Needs

In my online class, Desert Gardening 101, I teach my students that watering deeply is as important as the time of day that you water. The best time to water is early in the morning.  Watering plants in the afternoon is not as useful since plants allocate their resources at that time toward surviving the stresses of the heat and so they do not take up water as efficiently.  

4. Mulch for Cooler Soil and Moisture Conservation

Heatproof Gardening tips

Mulch plays a crucial role in heatproofing your garden. It helps regulate soil temperatures, keeping them cooler during the summer while conserving moisture – essential for plant health. Explore unconventional mulch options, including fallen leaves, pine needles, and even fallen flowers, and learn how they can enhance your garden’s well-being.

A bonus is that they also help to prevent weeds from taking root.

Heatproof Gardening tips

Be Creative with Mulch Components

Let’s take a minute to rethink our definition of what makes an excellent mulch.  

While shredded bark and wood chips may come to mind, did you know that fallen leaves, pine needles, and even fallen flowers can also serve as a mulch?  That is how nature does it.

Be Cautious with the Leaf Blower

So, the next time you are tempted to whip out your leaf blower, how about directing it toward the base of your plants where the leaves and flowers can serve as a mulch?

They will also help to improve the soil around your plants as they decay.

5. Opt for Succulents and Heat-Tolerant Shrubs in Containers

Tip for Heatproof Garden

While growing pretty flowers in containers is relatively simple in fall, winter and spring-summer can be another matter entirely.  Often, it can be hard to grow flowering annuals in pots throughout the hot summer.

The reason for this is that the soil around the roots of container plants is hotter than if grown in the ground.

Critical Top Soil

This is especially true for the outer 6 inches of soil which heats up in response to air temperatures and the hot container.  As a result, annuals can wilt and struggle to produce flowers in summer.

Succulents are a great way to enjoy attractive container plantings throughout the year, not just in summer.  Their ability to store water is what makes them an excellent choice for containers.

If you want to grow something else besides succulents, how about trying heat-tolerant shrubs? Bougainvillea does great in pots as does lantana.

Caring for Heat-Stressed Plants

Another tip for containers is to leave them empty in the summer months and wait until fall to plant them.  

When thinking in terms of growing plants in containers in hot climates, bigger is better – at least 2 feet wide at the top.  The larger the pot, the more soil and therefore, more insulation for the roots from the hot outer zone.

So what can you do if you do have plants that are struggling in the heat – particularly during a heatwave?  

Other than replacing them, you can provide them with temporary shade such as a patio chair strategically placed so that it protects it against the afternoon sun. A light spraying of water over the plant and surrounding area in the evening can help reduce the temperature – don’t do this when the sun is out, or you may burn the foliage.
