Pruning tree suckers in the summer desert garden

Navigating the Hot Early Summer in Your Desert Garden

The Scorching Reality of Early Summer

I don’t need to tell you that early summer desert garden is hot. In mid-June, we typically experience several days of extreme heat. I have many people who ask me what garden tasks CAN they do in their garden right now.

Well, the answer is an easy one…

Do as little as possible.

Embracing Minimalism in Garden Tasks

June is a very stressful time of year for plants because it is very hot and dry so it makes sense to heatproof your garden. Both of these conditions make it hard on plants. In fact, June is the hardest time of year for most plants.

In other words, don’t add new plants, do unneeded pruning, or fertilize.

If you find yourself with new plants still in their nursery pots, put them in a shady spot and water them regularly as they will dry out fast!

Careful with New Additions and Pruning

Pruning is also stressful for plants so limit your pruning to getting your trees ready for monsoon season. If you have some suckers growing mature trees (see photo above), you can prune them off.

Don’t fertilize plants now. Most plants don’t need it with the exception of flowering annuals, herbs, vegetables, and smaller palm trees.

Keep a Watchful Eye on the Summer Desert Garden Plants

In the meantime, get out early in the morning before it gets too hot to make sure there aren’t any plants that are struggling. You may need to add more water or provide temporary shade.

Toward the end of June, the monsoon season will be on its way with extra humidity and hopefully rain, which will provide some relief for plants.

The Reality of Vegetable Gardening: Unveiling the Secrets

The Pressure of Unrealistic Standards for Vegetables

Have you ever found yourself intimidated by fashion magazines filled with beautiful celebrities and models who are then photoshopped to remove every little imperfection? Or perhaps an Instagram account where the home is filled with natural light, dust-free, and no mislaid items anywhere?

I must admit that I don’t like to follow accounts like that as they promote an unrealistic view and leaves me feeling like something is wrong with me when I don’t look perfect and my house doesn’t either.

Escaping Unreal Expectations

This type of unreal perfection extends to the garden too! Just between you and me, I’ve been to many gardens that are highlighted on social media and they never look quite as good in person.

Believe it or not, vegetables also fall into this unrealistic realm when shown in magazines and online. Articles filled with photographs of perfectly-sized vegetables without a speck of dirt on them can be intimidating to the average vegetable gardener.

Unearthing the Dirty Secret of Vegetable Gardening

dirty secrets of vegetable gardening

Well, I’m here to tell you the truth and reveal two dirty secrets of vegetable gardening with some assistance from my little helper. 

My granddaughter, Lily

Meet Lily: A Gardening Companion

This is my granddaughter Lily who loved to help me in the garden when she was little. She was always a willing helper when it came time to harvest vegetables from my garden.

Toward the end of spring, it was time to harvest the last head of broccoli, pick the carrots, pull the garlic, cut parsley, and harvest the first of our blackberries.

The Dirty Secret of Vegetable Gardening

The Real Harvest

This is what our harvest looked like. Not particularly photo-worthy for a magazine or social media, is it? But, this is the reality of what it looks like.

The Dirty Secret: Vegetables Grow in Dirt

If you haven’t guessed the secret about vegetable gardening – it’s that it is DIRTY!

The Dirty Secret of Vegetable Gardening

Think about it – vegetables grow in the dirt.  They don’t come out clean.  In fact, it can take a while to clean the dirt away.

Lily was excited to help me clean the vegetables, so she would fill her ‘My Little Pony’ cup over and over and pour them over the carrots.

In fact, freshly harvested vegetables leave dirt behind on counters, floors too!

And those shiny, clean garden tools and spotless gloves? They don’t exist in a real garden.

Now, here is another secret of vegetable gardening…

The Dirty Secret of Vegetable Gardening

The Imperfect Shapes and Sizes are Normal

“Not all the vegetables are the same size and come out unblemished.”

The Dirty Secret of Vegetable Gardening

Here are four carrots that I harvested from the same garden.  As you can see, they are all different sizes.

The tiny ones, came from an area where I accidentally dropped a small pile of seeds. The large one was a result of an area in the garden that received too much water and the carrot was so big that it broke off as I attempted to pull it out.  

The Dirty Secret of Vegetable Gardening

Of course, any decent photo would display only the ‘normal-sized’ carrots – but that is not necessarily the truth of what a real garden harvest would look like.

Lily’s Tigger was excited to try some carrots.

Garlic of All Sizes

Here is another example. Our crop of garlic was bountiful. But, notice that there are not all uniform sizes.

While the majority of the garlic harvest is made up of normal-sized garlic heads – there are some very small and some giant heads.

The Illusion of Garden Perfection

But of course, that is not what you see when people typically show off their garden harvest – especially when they are to be photographed.

First, only the most attractive vegetables are shown – ones with no blemishes and uniform size. Second, all the dirt is removed. And finally, the decorative dish towels come out for an attractive background.   

The Dirty Secret of Vegetable Gardening

I have several decorative dish towels that have never seen a dish and I use them when I photograph vegetables, herbs, etc.

The Dirty Secret of Vegetable Gardening

Here is my ‘perfect’ garlic harvest. What is interesting is what you DON’T see. All of them are nicely shaped, roughly the same size, and most of the dirt is gone. This is NOT what they look like when they come in from the garden.

The Dirty Secret of Vegetable Gardening

The Best Advice is to Embrace Imperfection

So remember that vegetables aren’t perfectly clean, they may have blemishes and come in all sizes and shapes. So, when you harvest vegetables, don’t worry about perfect-looking vegetables. Remember, it’s the taste that matters!

My Secret Vegetable Gardening Tool…

Less water doesn’t mean a boring garden. Here are 5 tips for a beautiful, dry climate garden that saves water.

Have you ever noticed circular areas missing from your leaves? If so, you aren’t alone. The other day I noticed several of my plants with neat semi-circular sections missing. But, was I worried? Nope, and I’ll tell you why in my latest garden video.

The Enigmatic Damage to Leaves

A Puzzling Leaf Discovery

Noelle: Hey there, fellow garden enthusiasts! Today, we’re diving into a bit of a mystery. As I was strolling through my garden, I couldn’t help but notice something quite peculiar – several of my plant leaves had neat, semi-circular sections missing. Now, I know this might raise some alarms for many gardeners, but fear not, for I’m here to share some insights and reassure you that it’s not as ominous as it might seem.

Noelle: First things first, let’s take a closer look at these mysterious leaf patterns. You can see here on this rosebush, there’s a semi-circular chunk missing from one of the leaves. And over here on this hibiscus, another one. So, what’s going on? Is it some nefarious garden pest?

The Twist in the Tale of Leaves

Noelle: Well, here’s the twist – it’s not a pest at all! In fact, this leaf damage is quite natural and not something to fret over.

You see, the culprits behind these neat, semi-circular holes are none other than the remarkable leafcutter bees. Leafcutter bees are a type of solitary bee, and they are truly fantastic pollinators. What might appear as leaf vandalism is, in fact, a vital part of their unique nesting process.

Leafcutter bees utilize these semi-circular leaf sections to construct their nests. If you take a closer look, you might even spot some of these leaf sections tucked away in the nooks and crannies of your garden.

The Precision of Leafcutter Bees

Meticulous Craftsmen

Noelle: Leafcutter bees are known for their precision. They cut these perfect curves from the edges of leaves, and they’re surprisingly meticulous about it. The remarkable thing is that these bees aren’t interested in damaging your plants; they’re simply striving to build a safe and cozy space for their offspring.

Beneficial Garden Partners

Noelle: Now, here’s the best part – these bees are great for your garden! As they visit your plants to collect nectar and pollen, they’re inadvertently pollinating your flowers. This pollination process is an essential aspect of maintaining a healthy garden ecosystem.

Embrace the Leaf Patterns

A New Perspective

Noelle: So, the next time you come across these mysterious leaf patterns, don’t panic. Instead, take a moment to appreciate the hard work of these industrious leafcutter bees and the positive impact they have on your garden.

Learning from Mistakes in the Garden: A Green Thumb’s Journey

Embracing the Reality of Gardening

Do you know someone who has a green thumb? Usually, it’s someone with a beautiful garden that stands out among their neighbors with thriving plants that flourish. 

While you may think people with green thumbs are born and not made, I’ll let you in on a BIG secret – behind every green thumb is a trail of many dead plants.

Behind the Scenes of a Green Thumb

dead plants and a not so green thumb

It’s true. There isn’t a single experienced gardener who has never had a plant die in their garden. Of course, someone with a green thumb may be hesitant to reveal this fact, and you may not notice because dead or failing plants are usually pulled out before people notice.

green thumb disaster dead plants

I’m not exempt from this either – I’ve had many plants die on my watch.

Factors That Affect Plant Health and Your Green Thumb

Believe it or not, the fact that plants die in your garden helps you to become better at growing them. While your first inclination may be to get frustrated about the loss of a plant, look at it as a gardening lesson instead.

“Every dead plant is an opportunity to learn about what went wrong and how to avoid it in the future and become a better gardener in the process.”

There are several factors that can affect whether or not a plant does well.  These include the following:

1. Climate Adaptation

Is it well-adapted to your climate?

2. Proper Exposure

Was it planted in the right exposure (sun, filtered sun, or shade)?

3. Irrigation Needs

Did it receive the proper amount of irrigation?

4. Maintenance Practices

Was it maintained correctly (pruning, fertilizing)?

Green Thumb Research and Experimentation

Researching plants before purchasing them will help you to avoid potential problems. But often the best way to learn how a plant will do is to grow them yourself.

Of course, it’s never a good idea to put a shade-loving plant in full sun, or vice versa as you’ll probably be replacing it soon.

As a horticulturist, I experiment in my garden with newer plants that have come onto the market. Several years ago, I planted several ‘Blonde Ambition’ (Bouteloua gracilis) grasses. I had heard a few different tips about how to grow them and the best exposure – one says that filtered sun is a must while another person says it can handle full sun. So, I am trying them out in my front yard to see for myself where they will receive filtered shade until the afternoon when they will be blasted by the sun. UPDATE – they do best in full sun 🙂

*One fun bonus of being a horticulturist is that growers often send plants for free so I can try them and give them feedback about how they grow in a low-desert garden.

The Role of Nearby Trees

Other things that can affect how new plants will do are nearby plants – specifically trees.

A tree that creates dense shade will make it difficult for many flowering plants to do anything but grow foliage at the expense of flowers. However, filtered shade from desert natives such as mesquite and palo verde create an ideal environment for many blooming plants that enjoy a little respite from the full sun.

Unpredictable Nature of Gardening

Sometimes, there isn’t much information available on new plant introductions and how they will do in an area with extreme weather such as our hot, dry one.  In this area, a grower sent me plants to see how they would fare in a low desert garden. From past experience, I knew that salvia would need some shade, but the lavender was a mystery. I’ve seen some other species of lavender doing well in full sun while others doing well in filtered shade.

Green Thumb

As you can see, the ‘Meerlo’ lavender did very well in my zone 9 garden even though the actual information on the plant tag states that it does best in zone 8 and below.

Green Thumb Lessons

This is a lesson that I could have only learned by trying out this plant in my garden. While it could have died, it didn’t and I’ve learned from the experience, which adds to my overall garden knowledge. 

So, the next time you find a dead plant in your garden, see if you can figure out why it died and learn from it. Sometimes plants die when they should be thriving for no apparent reason. Nature isn’t always predictable and sometimes you may have no answers, but you’ll be surprised at what you can learn, and before you know it, your thumb may slowly turn ‘green’.

Cultivating Wildflowers: Nature’s Colorful Display

The Beauty of Spring Wildflowers

One of spring’s many joys are the fields of wildflowers that we often see growing along the side of the road.  It is one of the many miracles of nature how such lovely flowers can grow in the wild without any help from people.

I find it kind of ironic that if we want to grow these flowers of the wild in our own garden we  have to give them a little assistance to get them going.  But, the preparation is fairly simple and the rewards are definitely well worth the effort.

Planting for a Spring Show

To achieve a breathtaking spring wildflower display, it’s crucial to plan ahead. When it comes to wildflowers, autumn emerges as the ideal time for sowing seeds that will later burst into vibrant spring blooms. This strategic timing allows the seeds to establish strong root systems during the cooler months, ensuring they’re well-prepared to flourish when spring’s gentle warmth and longer days arrive.

So, as summer transitions into fall, seize the opportunity to sow the seeds of nature’s beauty in your garden, and you’ll be rewarded with a picturesque wildflower spectacle come springtime.

Lessons from a First Wildflower Garden

I’ve planted wildflower gardens throughout my career, but I’ll never forget my first one.  It was on a golf course and I sowed quite a bit of wildflower seed in that small area – and I mean a LOT of seed.  The wildflowers were growing so thickly together and probably would have looked nicer if I had used less seed and/or thinned them out a little once they started to grow.  But, I loved that little wildflower garden.

Embrace Wildflowers in Your Garden

If you have a fondness for wildflowers and the enchanting beauty they bring, consider carving out a dedicated space within your garden to cultivate your own captivating wildflower haven. By allocating a portion of your garden to these lovely, untamed blooms, you not only embrace the allure of the wild but also foster a unique and vibrant ecosystem right in your backyard.

With some thoughtful planning and care, you can create a harmonious blend of native or adapted wildflowers that not only adds natural charm but also supports local pollinators and wildlife. So, why not embark on the journey of nurturing your personal wildflower oasis and experience the wonders of nature’s artistry up close?

Rediscovering the Desert’s Beauty in Fall

As summer begins to slowly fade and the heat begins to dissipate, the Southwestern garden comes alive with second spring.

"Second Spring" in the Southwest Garden

In the absence of scorching 100+ degree temperatures, both plants and people reawaken to the vibrant beauty of the desert landscape during the fall season.

The Allure of Autumn is “Second Spring”

When people talk about their favorite season, many will tell you that spring is the time that they enjoy the most as their gardens come alive, spring forth with new green growth and colorful blooms. But in the desert Southwest, there’s another season that deserves just as much acclaim – fall, often referred to as the “second spring.”

While spring is a glorious time in the desert landscape with winter blooms overlapping with spring flowering plants along with cactus flowers – it isn’t the only ‘spring’ that the desert experiences.

A Season of Renewal

Fall in the desert brings a rejuvenating touch. The cooler temperatures breathe new life into plants, coaxing them into refreshed appearances and prolonging their flowering displays. Irrigation becomes less of a chore. Birds, butterflies, and various wildlife also make a prominent return during the daytime hours.

The Great Outdoors Beckons

With the arrival of fall, desert residents find themselves irresistibly drawn outdoors. Whether it’s leisurely walks, al fresco dining, or simply working outdoors, the comfortable temperatures and captivating landscapes make every moment spent outside a delight.

Fall is the ideal season for making alterations to your garden. It’s the perfect time to replace thirsty, old plants with drought-tolerant alternatives or expand your outdoor living space by adding new features like patios or pergolas.

Second Spring Planting for the Future

Regardless of your garden’s location, fall stands as the prime season for introducing new plants to your landscape. With three growing seasons ahead, it offers them the opportunity to establish robust root systems before the next scorching summer arrives.

No matter what garden region you live in – second spring is the best time of year to add new plants to the landscape as it provides plants with three seasons in which to grow a good root system before the heat of the next summer arrives.

A few weeks ago, I had the opportunity to take another photo of a landscape I passed by in a neighborhood where I had just finished up a landscape consultation. I was shocked at the mushroom shaped shrubs.

The Pitfalls of Shrub Pruning Mistakes

Sadly, I often see examples of truly ‘interesting’ or should I say ‘bad’ pruning.  I drove by this landscape and then made a U-turn so that I could take a quick photo…

improper shrub pruning

Shrub pruning

I don’t know about you, but these Texas sage shrubs look like mushrooms, don’t you think?

Sadly, pruning these beautiful flowering shrubs this way robs them of their flowers, increases maintenance, creates dead wood, and shortens their life.

Misguided Pruning in Strange Shapes

While there are quite a few shrubs that take well to repeated formal pruning – doing this to flowering shrubs should be avoided.

I must admit that I have seen Texas sage and other flowering shrubs pruned into many different shapes…

But, let me be frank – shrubs aren’t meant to be cupcakes, frisbees, or gumdrops

Why You Should Avoid Improper Shrub Pruning

Here are just a few reasons why…

1. Energy Deprivation

It removes the leaves needed for the shrub to make energy for itself

2. Increased Growth and Maintenance

Excessive pruning actually makes your shrubs grow faster, which equals MORE maintenance

3. Water Demands

Shrubs pruned often require more water as they constantly work to replace foliage lost

4. Shortened Lifespan

Continued shearing will shorten the lifespan of your shrubs

5. Aesthetic Impact

Green ‘blobs’ are ugly compared to beautiful flowering shrubs

Join Our Online Shrub Pruning Workshop

If you are tired of the time and money it takes to maintain flowering shrubs the ‘wrong’ way. I invite you to join me in my online shrub pruning workshop where I will teach you the right way to prune.

Imagine your outdoor space filled with beautiful, flowering shrubs instead of green ‘balls’. Believe it or not, the shrubs in the photo above are the SAME plant – they have just been maintained differently. The one on the left takes much more money and time and the other thrives with pruning once (or twice) a year.

In my online class, I show you how to work with your landscaper or how you can take care of your shrubs yourself. Got ‘green balls’ already in your landscape? I’ll teach you how to rejuvenate them and the best time of year to do it.

So, ditch the ‘green blobs’ in your yard and learn how to prune with confidence – it’s much easier than you think. Learn more here and what students have to say about the class.

Exploring the Beauty of the Desert Museum Palo Verde

Lovely flowering Desert Museum Palo Verde Tree

‘Desert Museum’ Palo Verde Trees

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

Avoiding Storm Damage of the Palo Verde Tree

Fallen ‘Desert Museum’ Palo Verde trees after a monsoon storm

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

Understanding Wind Damage Concerns

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

Personal Success with Desert Museum Palo Verde

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

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

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

1. Water deeply to a depth of 3 feet.

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

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

A blooming Desert Museum Palo Verde Tree

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

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

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

Several Palo Verde Trees grouped together

Trees that have been pruned up too high (lion-tailing)

3. Prune your tree correctly.

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

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

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

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

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

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

The Sunburn Experience: Not Just for Humans

Have you ever had a sunburn? Maybe a better question is, “Who hasn’t?”

Well, did you know that many plants get too much as well?

Sunburned Citrus: A Common Concern

On a recent visit to a client who was worried about her newly planted citrus trees.

new citrus trees planted in pots.

Sunburned Citrus

The Leaf Yellowing Dilemma on Citrus Trees

This particular client has a large courtyard with several new citrus trees in pots. Her citrus trees, planted in spring, showed yellowing as summer progressed.

sunburned citrus leaves

Now yellow leaves can indicate a number of different problems.  In this case, the diagnosis was rather simple – her citrus tree has a case of sunburn.

Common Signs of Sunburned Citrus and Other Plants

– The areas of the leaf that are yellow are in the center and NOT along the tips or edges.

– Often, the yellow areas begin to turn brown.

– Signs normally occur in the summer months.

– The sunburned leaves are usually located on the south and west-facing parts of the plant.

– This particular citrus tree is in an area that receives reflected, afternoon sun.

Citrus-tree-in-container-ASU


How to Prevent Sunburned Citrus

In this case, the solution is simple. Move the citrus tree to another part of the courtyard that receives afternoon shade is all that is needed to prevent further sunburn damage. Another choice is to put 50% shade cloth on from mid-May through September.

Citrus do best when planted at least 10 – 15 ft. away from walls. Unfortunately walls absorb the heat of the day and re-radiate it out.

Avoid planting where they get the full force of afternoon sun.
