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)

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? 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)

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.

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.

Use in areas that receive filtered sunlight.

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

‘White Cloud’ Texas Sage (Leucophyllum frutescens)

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

If given enough space, ‘White Cloud’ Texas Sage can grow large, 6+ feet tall and wide. 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, as this decreases flowering and is not healthy for this type of shrub. Hardy to zone 7, this shrub looks great as an informal hedge or against a wall.

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

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 and is 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, there are more to consider. Check out more in Part 2!

Too Much Salt Isn’t Good For You OR Your Plants…

Arizona garden, AZ Plant Lady Classes, California desert garden, desert gardening, Landscape Problems, Nevada garden, Shrubs, Southwest garden

I have a weakness (well, one of many) to confess to you today….

I absolutely love salt.

In fact, I have a theory that the reason that so many people love french fries is not the potatoes or the fat it is fried in. No, it is the salt that you put on them afterwards. I mean, can you imagine eating an unsalted french fry?

In preparation for this blog post, I went through my kitchen and pulled out all of my salt & pepper shakers.

It’s kind of embarrassing isn’t it? I have so many.

But in my defense, I must admit that I collect different types of pottery and need salt and pepper shakers for each set.

My husband made me my wooden salt cellar, which I keep near the stove when I cook.

Now, I do not use as much salt as I used to. In fact, I am trying to be better about it. When I visited the doctor earlier this week for my physical, I still had low blood pressure, much to my relief.

Well, we all know that too much salt is bad for you and can lead to health problems such as high blood pressure. But did you know that too much salt is not good for your plants as well?

Plants don’t get ‘high blood pressure’ with too much salt, but they do have another problem that shows up.

They get brown tips on their leaves, which we call ‘salt burn’.

Here is another way that you can tell plants are getting too much salt. Shallow watering causes the water in the soil to evaporate quickly, leaving behind the salts. The salts look like a white crust on the soil around your plants.

At this point you may be wondering how plants get too much salt?

Well, both our soil and water have naturally occurring salts in them. This is especially true in the Desert Southwest where our water is somewhat salty and our soils can suffer from salt build-up due to high evaporation.

So what do you do if you have indoor or outdoor plants that have brown tips?

The solution is very easy.

Water deeply.

That’s it!

Here is a shrub with signs of salt build-up that I encountered with one of my clients during a landscape consultation. He had other shrubs that looked similar.

I will tell you what I told him:

If your outdoor plants look like this, water the affected plant with your hose on a slow trickle for at least 2 – 3 hours. This helps to ‘leach’ or flush the salts away from the roots.

Thereafter, adjust your irrigation schedule so that your shrubs are watered to an approximate depth of 18 inches each time. Sadly, most people water too often, too shallowly, and not long enough.

For example, I water my shrubs and perennials every 3-4 days in the summer. It takes approximately 1.5 to 2 hours for my plants to be watered to a depth of 2 feet. Of course, the time it takes to water that deeply is different for each landscape and depends on various factors, including soil type and water pressure.

If your houseplant has brown tips (salt burn), you can flush the salts out by deeply watering it. Put your plant in the sink or bathtub and let water slowly trickle on it for 1 – 2 hours.

I cover landscape irrigation in depth with my students in my online course, Desert Gardening 101. However, for those looking for advice right now, here’s what I recommend: Search your city’s website (or water provider) for watering guidelines —most have schedules, including recommended depths.

So, in closing, I’ll leave you with these two tips:

Be sure to limit your salt intake AND water your plants deeply to prevent salt burn.

Plant Disease: Oleander Leaf Scorch

Arizona garden, California, California desert garden, desert gardening, Landscape Problems, Shrubs

Love them or hate them, oleanders have a firm foothold in the desert landscape where they are usually seen creating living green ‘walls’ in order to provide privacy.

Their popularity is due in large part to several characteristics:

– Their evergreen foliage provides the rich, dark green color that many miss living in the desert.

– Oleanders are easy to grow, with little to no fertilizer and are drought tolerant once established.

– They add beauty to the landscape spring through fall with their flowers.

While oleanders’ popularity is still holding on, a fatal disease that affects them has spread from California and is now being seen increasingly in Arizona.

Oleander leaf scorch (Xylella fastidiosa) is a bacterial disease that plugs up the vascular system of affected oleanders, eventually making the movement of water throughout the plant impossible.

This disease is spread by flying insects called sharpshooters. These small insects (1/4 inch long) become carriers of the disease when they feed upon an infected oleander. Thereafter, they spread it to every other oleander they feed upon.

Oleanders in Southern California were first diagnosed with the disease in the early 90s, and it was just a matter of time before it spread to Arizona.

Advanced stages of oleander leaf scorch

Oleander leaf scorch was first diagnosed in Arizona in 2004. Its spread has been slow but inexorable.

I have seen several cases of this disease during landscape consultations, including one that I did yesterday.

The homeowner had a very large, over 20-year-old oleander hedge that provided privacy from his neighbors.

What may look like some browing leaves in this small branch is one of the classic symptoms of oleander leaf scorch.

Oleander leaf scorch

Close up, you can see the brown outer leaf margins, which are characteristic of oleander leaf scorch. (This is not to be confused with drought symptoms, which cause discoloration of the middle of the leaf.)

As we continued to walk along the row of oleanders, the infected oleanders were interspersed between healthy ones. The reason for this is that the nature of flying insects is that they hop from one plant to another, but not necessarily the next plant – they may fly 3 shrubs away before feeding again or to the next yard or block.

Symptoms of oleander leaf scorch

This oleander showed another type of browning symptom of oleander leaf scorch with the tips looking ‘scorched’.

It’s important to note that salt burn resulting from drought or shallow irrigation can cause similar symptoms as shown in the photo below:

Drought-stressed oleander leaves

Note the middle of the oleander leaf is affected in the case of drought stress. While unsightly, the oleander pictured above, does NOT show signs of oleander leaf scorch.

Initial signs of oleander leaf scorch.

Back to the oleanders showing signs of oleander leaf scorch – I could see the beginning of symptoms with lighter green alongside darker leaves by looking closely at seemingly healthy oleanders. The signs of the disease don’t show up all at once in the beginning. Often, it starts out with a branch here and there showing signs initially that will gradually progress throughout the entire plant.

It’s important to note that once an oleander has been infected with this disease, the entire plant has it – not just the branches that initially show the first signs.

Lower leaves showing the beginning symptoms of oleander leaf scorch.

So, what is the treatment for oleander leaf scorch? Sadly, there is no cure, and once infected, it will eventually kill oleanders over a 3 – 5 year period.

Some experts recommend pruning out affected branches to improve the appearance of infected oleander shrubs for the short term. But they will die.

I recommend removing infected oleanders right away to help keep the disease from spreading.

Initial signs of oleander leaf scorch

Consult with an expert if you suspect that your oleanders are infected. Problems with irrigation, nutrient deficiency, and salt burn can mimic some of the symptoms of oleander leaf scorch, and a horticulturist or other landscape expert can help you rule out other causes. Ultimately, positive identification of oleander leaf scorch can only be made by lab tests through your local cooperative extension office.

Can you simply get rid of infected oleanders and start over with new ones? The answer is “no.” The disease is already present in the local sharpshooter insect population, and it is only a matter of time before it infects your new oleander shrubs.

I recommend using Arizona rosewood (Vauquelinia californica) or hopbush (Dodonaea viscosa) as an alternative to oleanders. Both are evergreen, recommended for use near pools, make a great hedge, are drought tolerant, and attractive.

10 Fuss-Free Plants for the Summer Garden

Agave, Arizona garden, Cactus/Succulents, California desert garden, desert gardening, Drought Tolerant, Fuss Free Plant, Las Vegas gardening, Nevada garden, New Mexico garden, Shrubs, Southwest garden, Southwest Texas garden, Succulent Gardening

Artichoke agave (Agave parryi ‘truncata’), golden barrel cactus (Echinocactus grusonii), and lady’s slipper (Pedilanthus macrocarpus),

Does the idea of having to venture outside, when temperatures are above 100 degrees, to care for your garden have you thinking twice? I must admit that there have been times when I have let the plants in my landscape fend for themselves in summer after setting the irrigation controller. But, there is often a price to pay afterward when you have to play catch up with extra pruning and other maintenance.

There are however many different plants that thrive in summer with little fuss allowing you to enjoy the comforts of your air-conditioned home while viewing your beautiful garden through the windows. Here are some of my favorite fuss free plants for the summer garden.

Mexican Honeysuckle (Justicia spicigera)

Mexican honeysuckle has lush green foliage and produces tubular orange flowers throughout the entire year. They do best in filtered shade and attract hummingbirds. I like to plant them underneath trees such as mesquite or palo verde.

Learn more about Mexican honeysuckle.

Artichoke Agave (Agave parryi ‘truncata’)

Artichoke agave is highly prized for its rosette shape, and it’s easy to see where it got its name. The blue-gray color and maroon edges add great color contrast to the garden when it is placed alongside plants with dark and light-green foliage.

Of course, these are but one species of agave that would make a delightful, fuss-free addition to the summer garden. I also recommend cow’s horn agave (Agave bovicornuta), smooth-edge agave (Agave desmettiana), and Victoria agave (Agave victoria–reginae) to name a few.

‘Summertime Blue’ (Eremophila ‘Summertime Blue’)

‘Summertime Blue’ is a delightful shrub that needs next to no maintenance throughout the year and decorates the garden with its bright green foliage and violet-blue flowers that appear spring through fall. It grows slowly but will reach approximately 6 feet tall and wide. If given enough room, it can go a year (or two) before needing pruning. While you may have to look around for a nursery that carries it, it’s well worth the effort. It is also usually found at the Desert Botanical Garden’s spring and fall plant sales.

Lady’s Slipper (Pedilanthus macrocarpus)

Lady’s Slipper is a uniquely shaped succulent with thornless stems that have a ‘Medusa-like’ growth habit that is more pronounced in light shade. The upright stems add a welcome vertical element to the landscape, and small orange flowers are produced off and on through spring and fall. They can be grown in containers or planted in the ground and do well in full sun or light shade.

Bush Lantana (Lantana camara ‘Radiation’)

Bush lantana is a familiar sight to many who live in arid climates like ours. This species of lantana is slightly different than the trailing gold and purple lantana. It has larger leaves, grows taller, and has multi-colored flowers that vary according to the variety. Bush lantana is a great choice for a colorful summer garden as they are seemingly heat-proof.

Totem Pole ‘Monstrosus’ (Lophocereus schottii ‘Monstrosus’)

Totem pole ‘Monstrosus’ has become quite a popular addition to the desert garden and it’s easy to see why with its knobby shape. Another bonus is that they are almost always thornless, which makes them suitable for areas near entries or patios where a prickly cactus aren’t welcome. Plant in full sun in a row for a contemporary look or place next to a boulder for a more natural appearance.

Learn more about totem pole cactus.

‘Heavenly Cloud’ Texas Sage (Leucophyllum langmaniae ‘Heavenly Cloud’)

‘Heavenly Cloud’ Texas sage is well worth adding to your landscape for its lovely purple blossoms that appear off and on throughout the warm season, often in response to increased humidity. All species of Texas sage do well in summer and can be nearly maintenance-free if allowed enough room to reach their 8 foot tall and wide size as well as left to grow into their natural shape. This particular species blooms more than the more common ‘Green Cloud’ Texas sage.

Golden Barrel Cactus (Echinocactus grusonii)

Golden barrel cactus are wildly popular, and it is easy to see why with the globular shapes and yellow coloring. This cactus is quite versatile, able to grow in both sun and light shade. I like to use it in groups of three next to boulders or in a row. They also do well in containers planted singly or along with other succulents.

Red Bird-of-Paradise (Caesalpinia pulcherrima)

Red bird-of-paradise is one of the most iconic flowering shrubs in the low desert regions of Arizona. Also known as mexican bird-of-paradise and royal poinciana, visitors marvel at their beautiful flowers in shades of orange, yellow, and red. The striking blossoms appear in late spring and last into early fall much to the delight of hummingbirds. There is nothing to do to care for them in summer other than to marvel at their beauty.

Learn more about

red bird-of-paradise

Red Yucca (Hesperaloe parviflora)

Red yucca has the appearance of an ornamental grass, but its leaves are succulent. Coral-colored flowers are borne aloft on tall stalks off and on spring through fall – there is also a yellow variety as well. They look great all year, even when not in flower and are well worth adding to your outdoor space.

Stuck in a Prickly Situation…

Prickly pear

The next time you find yourself grumbling about having to prune your trees and shrubs – just be thankful that you don’t have to prune cacti at the Desert Botanical Garden.

While I have never had to prune a large bed of cacti, I have backed into cholla and other types of cacti early in my career. I’ve even had a piece stuck on the back of my leg – ouch!

I admit to being a bit clumsy and not always hyper-aware of my surroundings. Years ago, when I had a landscape crew, they would always be warning me about plant holes and prickly plants that I didn’t spot right away.

More recently, I was visiting a client and backed my heel into her golden barrel cactus. Several years later, despite my doctor trying to get it out, a piece of that thorn is still stuck in my heel. It doesn’t hurt anymore, and I just have a tiny bump on my heel as a memento.

However, some types of cacti, such as prickly pear and cholla, need to be pruned from time to time in a landscape setting.

Prickly pear can grow very large and spread. If you don’t have enough room, you may find yourself having to prune it back. When pruning prickly pears, make your pruning cuts where the individual pads meet. I like to use long-handled loppers, which work well and don’t require getting too close.

Cholla tend to drop segments on the ground, which is how they propagate. The segments will root in ideal conditions and grow a new cholla.

In a managed landscape, it is a good idea to clean the fallen pieces of cholla to help keep people from inadvertently getting it stuck to their shoes.

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.

purple flowering shrub — ‘Rio Bravo’ Texas Sage *(Leucophyllum langmaniae ‘Rio Bravo’)*.

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.

flowering shrubs growing in containers — 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.

Early Morning Birding Exploration

Arizona garden, AZ Plant Lady, az plant lady family, desert, Desert Animals, desert gardening, Hummingbird Gardening, Shrubs, Southwest garden, Trees

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.

Fall in the Desert Garden

Embracing the Desert Garden in Fall

Fall is my favorite time of year in the desert garden for two main reasons.

First, fall signals the beginning of the holiday season. And yes, I am one of those people who decorate for Christmas early. Thanksgiving dinner at my house is celebrated with a fully decorated tree in the background.

The Revival of the Desert Garden

Secondly, autumn marks a magical transformation in my garden, as it awakens from the trials of summer. It’s no secret that the scorching heat of the summer months can be taxing on our cherished green companions. However, the arrival of fall ushers in a series of remarkable changes that breathe new life into our botanical friends.

Lush and Vibrant

As keen observers of nature, we’ve likely noticed the remarkable resurgence of our plants during this season. The foliage appears lusher, the blooms more vibrant, and the overall health of our garden seems to rebound. It’s a phenomenon so profound that many desert gardeners affectionately dub autumn as the “second spring.”

This resurgence is no mere coincidence but rather a result of nature’s resilience and adaptation. As temperatures dip and daylight hours become more moderate, our plants find relief from the summer’s harsh extremes. They eagerly embrace this milder environment, seizing the opportunity to flourish once again.

Nurturing the Garden

In the desert, autumn isn’t just a season of change; it’s a reaffirmation of the enduring partnership between gardeners and the natural world. It reminds us that, even in the harshest of climates, with patience and understanding, we can create and nurture thriving gardens that mirror the vitality and resilience of the desert itself.

Foliage Rejuvenation and Vibrant Blooms in Your Garden

Here are some of the differences you may see in your plants this time of year:

Darker foliage has replaced the sun-bleached appearance of some plants due to less intense sunlight.
Flowering increases and the blooms may also appear more intense in color due to less intensity from the sun.
Some plants only bloom in fall, like black dalea (Dalea frutescens), cascalote (Caesalpinia cacalaco), and my favorite pink muhly grass (Muhlenbergia capillaris).

Showcasing the Fall Garden

In the section of my backyard, pictured above, pink muhly and white trailing lantana (Lantana montevidensis ‘Alba’) look especially vibrant in fall.

Pink trumpet vine (Podranea ricasoliana) dominates the back corner and blooms in spring and fall. I always know when cooler temps are on their way when they begin to bloom in September.

However, as autumn transitions into winter, the blooms in this area will slow and fade. A few hardy blooms may remain, but overall, the plants will slow down in their growth and flowering. The exception is my angelita daisies (Tetraneuris acaulis) which will bloom off and on through winter.

Discovering the Delights of Your Desert Garden

In the desert southwest landscape, where scorching sun and minimal rainfall summers challenge even the greenest thumbs, cultivating a thriving fall water-saving garden becomes a true art. Through careful planning and sustainable practices, enthusiasts uncover the secrets of nurturing vibrant cacti, resilient succulents, and colorful desert blooms.

What a joy to learn the delicate balance of conserving water while creating an oasis of life. Beyond the satisfaction of tending to nature’s wonders, desert gardening in the southwest unveils the beauty of resilient, sustainable, and breathtakingly unique landscapes. I invite you to take a walk through your garden and note the changes to your plants. This is a happy time of year in the garden!

Got Dead Plants?

Arizona garden, California desert garden, desert gardening, Landscape Problems, Las Vegas gardening, Shrubs, Southwest garden

Understanding the Mystery of Dead Plants

I’m pretty sure I know the answer to the dead plant mystery.

We have all likely experienced the death of a plant in our garden, and even though I am a horticulturist, I’m not immune.

Sometimes, plants die in my garden too.

The Perplexing Case of ‘Blue Bells’ Emu Bush

Here is a photo of my recently deceased ‘Blue Bells’ emu bush.

I was surprised to see that it had ‘kicked the bucket’ as its nearby neighbors were flourishing. Dead plants can tell a story.

So, the question I have to ask myself is, why did it die?

How to Figure Out Why a Plant Died in Your Garden

To determine why a plant died, here are some things to ascertain…

1. Recent Planting and Transplant Shock:

Was it planted recently? If so, it may not have had enough time to grow enough roots to survive summer. Transplant shock is a real thing.

2. Watering Issues Are a Concern:

Did it get enough water? Was the drip emitter plugged or broken? Sometimes we need to better educate ourselves on water irrigation.

3. Sun Exposure Extremes:

Was it planted in the wrong exposure? In other words, did it get too much sun or not enough? Both of these things can cause dead plants.

4. Climate Compatibility Can Cause Dead Plants:

Does the plant do well in our hot, desert climate? Or will it end up a dead plant because it is not built for the desert climate.

5. Pest Problems:

Were there any pest problems, such as ants around the roots or other unwelcome bugs? This can weaken the plant.

6. Overall Landscape Health:

Are identical plants in your landscape struggling too? If so, they might all be struggling due to a similar issue.

7. Soil Conditions are Important:

Is there a problem with the soil? Groupings of dead plants can sometimes indicate poor soil conditions.

Using these questions as guidelines, you’ll likely have the answer to why a plant has died.

However, in my case, the plant was a few years old, always did well, and the ‘Blue Bells’ nearby were thriving.

So, why did it die?

I don’t know…

Sometimes plants die, and we don’t know why. I realize this can be hard to accept without having the answer.

That is what happens in nature – things die, and we don’t always have the answers as to why.

In my particular case, I am replanting a new “Blue Bells” because I know it grows well for me in this spot. I ensured there were no unwelcome bugs in the soil and amended the soil with 1 part compost mixed with 1 part existing soil to give it a little ‘boost.’ You might find a different plant that works well for your garden.

I hope my new plant is happy…

By the time midpoint of summer heat arrives, I am firmly in ‘summer hibernation’ mode. I have past all the garden needs in hot early summer and moved on to trying to find a cool spot with a nice glass of lemonade.

Why Summer Hibernation Mode in the Desert

While much of the country stays indoors during the cold of winter, we desert dwellers flip that and spend the hottest days of summer safely ensconced indoors in the comfort of A/C.

Of course, cabin fever can hit, making us venture outside of our homes. That’s where summer getaways come into play.

I’m fortunate that there are many spots in Arizona (where I live) that are just a few hours from my house where the summer temperatures are blessedly cooler.

When my husband and I were young, we couldn’t afford to stay overnight in out-of-town destinations. But, we could go for the day. We would pack up our two young daughters and go on day-long adventures to the cool mountains and pack a picnic lunch. Oh, what fun we had!

Nowadays my husband and I travel to cooler spots and spend a few days. One of our favorite places is the town of Bisbee in southeastern Arizona.

There is a lot of history in there and we love to explore while enjoying the cooler temps. The photo above is a part of Bisbee called Lowell, which is preserved in time from the 1950s.

Garden Concerns for Extreme Southwest Heat

Speaking about the heat, I’ve heard from a number of people in my membership club who are worried about the lack of flowers they see on their shrubs and groundcovers.

Perhaps you have similar worries…

I want to assure you that this is normal in summer – particularly when monsoon rains have been sporadic and not regular.

Intense heat and dryness tend to make flowering plants slow down and a heatwave can burn flowers of certain plants. There are also a lot of fuss-free plants you can choose for the summer garden that bloom and look beautiful all season long.

Rest assured that they will come back by summer’s end to provide beauty to your outdoor space.
