“How much water do my plants need?”

I am often asked this question by desert dwellers and my answer is always, “That depends.”

desert-landscape

There are several variables that determine how much water plants need, along with the frequency of watering.

Variables include:

  • Type of soil (clay, sand, combination)
  • What kind of plant (native plants, higher water use flowering shrubs and ground covers, succulents, etc.)
  • Recommended depth of water
  • Desert region (low-desert, mid-altitude, high desert)
  • Efficiency of irrigation system
  • Water pressure (can vary between neighborhoods)
As you can see, there is no universal watering guideline in regards to how long to water or how often.

Let’s look into the variables a little more closely to help you determine what yours are:

 

SoilClay soils hold onto water longer than sandy soil. They take longer for water to permeate to the recommended depth. The result? Clay soils need irrigation less often than sandy ones but need to be watered for a longer length of time. Phoenix area soil tends to have more clay in them while those in the Palm Springs area are sandy.

Plants – Native or desert-adapted plants need less frequent irrigation versus those that come from tropical climates. Cacti and other succulents do well with infrequent irrigation.

Water Depth – Trees need to be watered deeply while ground covers and succulents do fine at a more shallow depth – shrubs fall in between the two.

Desert Region – Where you live in the desert matters when it comes to water and your plants. The differences include rainfall amounts, when the rain falls, high and low temps, and more. Residents of low-desert cities like Palm Springs and Phoenix need to add water to their plants more often than those who live in higher elevation regions such as Tucson.

Irrigation System – The older your irrigation system, the less efficient it is. This is due to mineral build-up within the system, which affects the amount of water that comes out. Also, old drip irrigation systems tend to accumulate leaks. The average lifespan for a drip irrigation system is 10-15 years. 

Despite these differences, what is a shared characteristic is that the vast majority of desert residents water too often and not deeply enough. This is usually due to lack of knowledge and thinking the ‘more is better,’ especially in the desert.
Landscapers are generally not a reliable source when it comes to scheduling irrigation – most recommend irrigating far too often.
 
So what is a desert dweller to do?
Thankfully, there is very useful information available for homeowners to help them figure out when and how much water their landscape needs.
 
Major metropolitan areas throughout the Southwest have excellent watering guidelines available for residents. The guidelines include the regional variables we have discussed so far.
Here are helpful links based on major desert cities (click the link for the city closest to you):
Watering guidelines are just that – guidelines. Circumstances may mean that you need to water more or less often, but these guides are a useful baseline to work from.
*One final note – before you implement a new irrigation schedule, it’s important to gradually wean your plants to the new one over several weeks. The reason for this is that it allows plants to become accustomed to the new schedule.

Yes, it does take a little work to figure out how much and often to water your plants, but these guides are incredibly helpful and will guide you along the way.

Do you have a citrus tree in your garden? I do.  
 
I have two trees – a Meyer lemon and a brand new ‘Trovita’ orange tree. 
 
As a child in California, we always had citrus trees in our backyard.  I would pick lemons from my favorite tree just off the back patio. Later, we moved to a larger ranch-style home that had several citrus trees. I honestly never paid much attention to them, because as a teenager I had more important things to think about – like boys and how to get perfect-perm for my hair (it was the 80’s).
 
Now as an adult (with permed hair thankfully in my past), I do pay attention to my citrus trees. Consequently, I look forward to the fragrant blossoms that cover citrus trees in mid-winter. As the blooms fade, tiny green fruit is left behind, which are baby citrus fruit. However, as spring progresses, some of the small, green fruit drop to the ground. Not surprisingly, this concerns gardeners who don’t understand why.
 
Well, let me put all your worries to rest.  This is a normal occurrence. Citrus trees produce more blossoms than it can grow into mature fruit. They do this in order to attract the most pollinators and after the flower petals drop, little green fruit is left behind, which ideally grow into large delicious fruit ready to harvest in winter. However, the tree cannot support that much fruit, so the tree figures out how much fruit it can grow to maturity and then drop the rest.
 
For those of you who have young citrus trees, I want to warn you that most of the little green fruit will drop. Citrus trees need a large root system and a lot of leaves to support a good amount of fruit and that only comes with age. So, if you see tiny, green citrus on the ground every spring – don’t panic. It is all part of the normal cycle of growing citrus.
Red-Hot-Tecoma-Shrub-Nursery-Container

Tecoma Red Hot

I am always on the lookout for new plants to the desert plant palette. Growers experiment with new varieties of more common plants in an attempt to find new colors, sizes, and more desirable characteristics.

This past fall, I was invited to visit Civano Nursery Farm, located in Sahuarita, 20 miles outside of Tucson. The main reason for the visit was to introduce me to their new Tecoma shrub hybrid called ‘Red Hot.’ This new plant is closely related to yellow and orange bells, which are both ones that I like to use when designing.

At the time of my visit, ‘Red Hot’ was not yet available to the public but was being grown throughout the Southwest as a test plant.

Civano Nursery Farm tour AZ Plant Lady

I met with Jackie Lyle, their Brand Development Manager, who plays an integral part in the introduction of new plants to the Southwest region.

Our tour began in the greenhouses where we explored their state-of-the-art automated systems and massive amounts of plants in all stages of growth. I was in heaven!

Civano Nursery Farm Tour AZ Plant Lady

I have never worked in a nursery or for a grower, so it was fun to see how they propagate plants from cuttings.

Greenhouse with Red Hot Tecoma shrubs

While touring the greenhouses, I got my first view of ‘Red Hot’ Tecoma. Instantly, I could see why there is so much excitement about this new variety. The foliage has the characteristic color of most Tecomas, but the leaves were somewhat smaller than yellow bells and more compact.

Red Hot Tecoma flowers

The vibrant red blooms are simply stunning and sure to draw hummingbirds to drink the nectar from their flowers.

‘Civano Select’ are plants created by the grower, which have slightly different characteristics than the more common species that they are a welcome addition to the desert plant palette. I was thrilled to view several of their ‘Select’ plants during our tour.

Bougainvillea-Civano-Nursery

As you can imagine, this is a bustling nursery, and there were shipments of plants headed out to job sites and other nurseries.

Whoever is getting these ‘Red Hot’ shrubs are in for a treat!

new-plants-desert-garden

And, guess who came home with her own ‘Red Hot’ shrubs? Me!

I am honored to receive two of these new shrubs, so I can share with you how they do in my Phoenix area garden. They are doing very well along the south-facing side of my house underneath the window by my kitchen eating area where I see them every day.

Oh, and of course, I also brought home other plants – autumn sage (Salvia greggii), Mt. Lemmon marigold (Tagetes lemmonii), ‘Mr. Liko’ pink gaura (Gaura lindheimeri ‘Mr. Liko’). Getting free plants is like Christmas to this horticulturist!

The great news is that ‘Red Hot’ Tecoma is now available at many local nurseries.

Want to see if this is the right shrub for your garden? Here are the stats:

‘Red Hot’ Tecoma

Size: 4 feet tall and wide

Exposure: Full sun, reflected sun

Bloom Season: Spring through Fall

Cold Hardiness: 15 degrees

Attracts: Hummingbirds

I will share the progress of my new ‘Red Hot’ shrubs and I encourage you to add this vibrant beauty to your garden!

 

‘Tangerine Beauty’ Crossvine (Bignonia capreolata ‘Tangerine Beauty’)

Spring in the desert is the most beautiful time of year with the majority of plants in the landscape bursting out with flowers. It’s also a very busy time for me with landscape consultations, speaking engagements, work in the garden, and family life. I love to document the happenings in my life by taking photographs with my phone, and I’d like to share a sampling with you. It’s a fun combination that includes colorful plants, spiky pots, snakes, roses and the prom!

No matter how busy I may be, the sight of a beautiful plant stops me in my tracks. It doesn’t matter how rushed I may be; I will always stop and take a photo. That’s what happened when I spotted this row of ‘Tangerine Beauty’ crossvines on our way into church. Even though we were running a few minutes late (as usual) I had to pause to admire the beauty of the lovely blooms and take a photo.

‘Tangerine Beauty’ does very well in the low desert garden. It has lush green foliage and orange/pink flowers that hummingbirds love. It needs a trellis or other support to climb up on and does well in full sun to filtered sun, but avoid planting along a west-facing wall as it may struggle in reflected sun.

entryway-desert-gardening-flowering-annuals-geraniums

As I mentioned earlier, I do a lot of speaking on a variety of gardening topics at the Desert Botanical Garden, public libraries, and also to garden groups. Upon my arrival to give a presentation at the Paradise Valley Country Club, I was greeted by this beautiful bed filled geraniums, foxglove, and yellow daisies. The spiky shape of agave adds welcome texture contrast in this area.

agave-planted-in-containers-arizona

Across the way, I spotted this dramatic example of spiky succulents growing in pots. Agave are excellent container plants, and their spiky shapes look fabulous along this wall. The plantings underneath the wall are well chosen as they do well in areas with full sun and reflected heat.

Here is a very different entry to another presentation I was to give at the Cave Creek Branch of the Phoenix Public Library. Two identical caution signs flank the raised metal bridge, which makes you look carefully before approaching. I know that libraries work hard to get kids to read, but these signs just might scare them off 😉

David Austin Olivia Rose

‘Olivia Rose’

Back home, the rose garden is in full bloom with my favorite ‘Olivia Rose’ completely covered in fragrant, delicate pink color. She flowers more than every other rose in the garden and for the longest, ensuring her favored status.

‘Darcey Bussell’

The best performing red rose in the garden is ‘Darcey Bussell,’ and she never disappoints as I view her vibrant blooms from my kitchen window.

David Austin rose Lady of Shalott

‘Lady of Shalott’

This rose is a relative newcomer to my rose garden. ‘Lady of Shalott’ was planted in the winter of 2018 and didn’t produce many blooms in her first year, which is typical of most new roses. However, this year, she is covered with roses in delicate shades of pink and peach.

On the home front, spring means that it’s time for the prom. I can hardly believe that my son is old enough – it seemed like it was just yesterday when I came home with a darling little two-year-old boy from China.

Kai’s favorite color is red, can you tell? It takes confidence to wear a bright color like this, and he does it so well. He is the youngest of four sisters, so this was my first time helping a boy get ready for a school dance. Honestly, it is a lot simpler – all he needed was help with his tie and his boutonniere.

I love spring and all the busyness that comes with it. How about you?

Firecracker Penstemon (Penstemon eatoni)

Have you ever noticed that spring has a way of surprising you in the garden? That is indeed the thought that I had earlier this week as I walked through my front landscape.

After spending a week visiting my daughter in cold, wintery Michigan, I was anxious to return home and see what effects that a week of warm temperatures had done – I wasn’t disappointed.

I want to take you on a tour of my spring garden. Are you ready?

pink blooming Parry's penstemon

Parry’s Penstemon (Penstemon parryi)

Penstemons play a large part in late winter and spring interest in the desert landscape, and I look forward to their flowering spikes.

flowering echinopsis Ember

Echinopsis hybrid ‘Ember’

One of the most dramatic blooms that grace my front garden are those of my Echinopsis hybrid cactuses. I have a variety of different types, each with their flower color. This year, ‘Ember’ was the first one to flower and there are several more buds on it.

blue flowering shrubby gerrymander

Shrubby Germander (Teucrium fruiticans)

Moving to the backyard, the gray-blue foliage of the shrubby germander is transformed by the electric blue shade of the flowers. This smaller shrub began blooming in the middle of winter and will through spring.

Calliandra red powder puff shrub

Red Powder Puff (Calliandra haematocephala)

This unique shrub was a purchase that I made several years ago at the Desert Botanical Garden‘s spring plant sale. If you are looking for unusual plants that aren’t often found at your local nursery, this is the place to go. This is a lush green, tropical shrub that is related to the more common Baja Fairy Duster. However, it only flowers in spring and has sizeable red puff-ball flowers. It does best in east-facing exposures.

flowering annuals Callibrochoa

Million Bells (Calibrachoa)

I am trialing a new self-watering hanging container that was sent to me free of charge by H20 Labor Saver for my honest review. I must say that I am very impressed. Growing plants in hanging containers is difficult in the desert garden as they dry out very quickly. But, this is a self-watering container, which has a reservoir that you fill, allowing me to have to water it much less often.

In the container, I have Million Bells growing, which are like miniature petunias. They are cool-season annuals that grow fall, winter, and spring in the desert garden.

severely pruned yellow bells

Yellow Bells recently pruned

Not all of my plants are flowering. My yellow bells shrubs have been pruned back severely, which I do every year, and are now growing again. This type of severe pruning keeps them lush and compact, and they will grow up to 6-feet tall within a few months.

Onions growing in my vegetable garden

This past fall, my daughters took over the vegetable garden. I must admit that it was fun to watch them decide what to grow and guide them in learning how to grow vegetables. They are already enjoying the fruits of their labor and onions will soon be ready to be harvested.

Meyer Lemon blossom

My Meyer lemon tree hasn’t performed very well for me and has produced very little fruit in the four years since I planted it. I realized that it wasn’t getting enough water, so I corrected that problem, and it is covered in blossoms – I am so excited!

fragrant chocolate flower

Chocolate Flower (Berlandiera lyrata)

Moving to the side garden, chocolate flower adds delicious fragrance at the entry to my cut flower garden. It does well in full sun and flowers off and on throughout the warm season.

purple flowering verbena

Verbena in bloom

In the cut flower garden, my roses are growing back from their severe winter pruning. Although the roses aren’t in bloom yet, my California native verbena is. This is a plant that I bought at the Santa Barbara Botanical Garden – I don’t remember the exact name, but it does great in my garden.

ripening peaches

Young peaches

I have some fruit trees growing in the side garden including peaches! I can just imagine how delicious these will taste in May once they are ripe!

flowers of apple tree

Apple tree blossoms

While the peaches are already forming, my apple trees are a few weeks behind and are still flowering. It surprises people that you can grow apple trees in the desert garden and they will ripen in June – apple pie, anyone?

I hope that you have enjoyed this tour of my spring garden. All of these plants are bringing me joy.

*What is growing in your garden this spring that brings you joy?

For my longtime followers, you may have noticed that I haven’t been blogging as regularly as before. Well, I am excited to tell you the reason why.

But first, a little background. I help desert gardeners in my work as a landscape consultant where I meet with my clients and give them the knowledge and tools that they need to create, grow, and maintain a beautiful outdoor space that thrives in a hot, dry climate.

Many of you know that gardening in the desert can be challenging and it is hard to find resources to help you to learn the “right” way to do things. As a result, my phone was ringing off the hook with people who needed my help. Unfortunately, there aren’t enough hours in the day to help everyone, and I soon became overwhelmed with work and exhausted.

So, I began looking for a way that I could reach more people to give them the help they needed. All winter long, I worked hard on my ‘new project’ and debuted it in January to a limited number of desert gardeners. I hoped that they would give me feedback so I could make sure that my new project was what they needed.

What I wasn’t prepared for was their overwhelmingly positive response! I can’t tell you how much that meant to me. I achieved my goal of reaching more people and helping them on their desert garden journey, and it is working!

And now, I’m finally ready to draw back the curtains and share it with you!

Here is what some of my current students have to say about Desert Gardening 101:

“This class has been very informative. We recently moved into a home in AZ with no landscaping in both the front and back yards. Having no experience in desert gardening and spending a lot of time online researching this subject. I came across the AZ Plant Lady and was happy to see there was an upcoming class on Desert Gardening. We signed up immediately.

This class is very helpful, and I’m sure it will keep us from making expensive mistakes in our new landscape and saving many hours of research. We can’t wait to start planting. Thank you for sharing your knowledge.”Laurie Wolf

 

“I have really enjoyed Desert Gardening 101 and have learned so much! Talk about a learning curve! Everything about gardening here is a complete 180! Yikes. I have killed more plants in the past three years, that I ever did in the many, many years I gardened in Milwaukee! I wish that I would have had the opportunity to learn all that I am learning now before we hired a landscape firm to landscape our yard.

We had a clean slate – a brand new construction with nothing but dirt surrounding our home! I knew very little about the desert, the plants and trees that grow best here and how to plant and care for them, soil to use, the watering “issue,” let alone design. We are now in the process of fixing the problems, thanks in large part to the knowledge I am gaining through Desert Gardening 101! I still have a ton to learn, but I’m making lots of progress with the weekly modules!

Thanks, Noelle for making this a very informative and worthwhile course for all of us trying to learn the ins and outs of desert gardening!Barb Terschan

 

“A Phoenix resident for many years, I recently moved from downtown to a house on the mountain preserve and wanted to flow into the desert with native and low water desert plants. That is when I found AZ Plant Lady and started learning. This class has been a huge help in this transition. I have learned I’ve been planting my new plants too deeply and watering way too much. The pruning session was an eye opener, also. Now I know when and how to prune my shrubs. The many plant suggestions provided have narrowed my search when visiting nurseries and has kept my focus on what really thrives in the desert. I am gardening with more confidence thanks to this course. Highly recommend!”Linda Yowell

Do you have a plant that DOESN’T bring you joy?

I do. There is one particular that has been bothering me for a while and I finally did something about it as I explain in the video below:

While there may be some sadness when removing a healthy plant, I confess that I didn’t feel that this time. The frustration that I feel each year with its under-performance in my garden that I was ready for it to go.

Here is the tiny orange tree that didn’t bring me joy.

Although it doesn’t show in this photo, there was a healthy root system on this tiny orange tree.

What plants do you have that no longer bring you joy?

winter-blooming-shrubs

Let’s face it, a winter landscape filled with frost-damaged plants isn’t the most attractive. During this time of year, I often find myself itching to grab my pruners and get rid of the ugly, brown growth on my bougainvillea, lantanas and yellow bells shrubs. But before I do, I keep repeating to myself, just a few more weeks…

Perhaps you have a similar urge to prune away all the brown too early. What helps me to stop grabbing my pruners is remembering that the dead outer growth of my summer-flowering beauties is protecting the inner part of the plant AND the fact that freezing temperatures are still a distinct possibility.

winter-blooming-shrubs

Feathery cassia and Valentine bush

And so, I will focus my attention on the winter-flowering plants that are adding beauty to my cool-season garden for now. If you don’t have any, I recommend Blue Bells (Eremophila hygrophana), Valentine bush (Eremophila maculata ‘Valentine’), and Firecracker penstemon (Penstemon eatoni), and feathery cassia (Senna artemisioides).

If you would like more information on this subject, I invite you to read “Got Brown Crispy Plants?”

So, what are you dying to prune back in your winter garden?

Valentine bush and feathery cassia

One of the things that I enjoy about living in the Southwest are the beautiful outdoor spaces. In particular, I am struck by the color and beauty in the winter landscape.

Now, for those of you who follow, know that I often take photos of ‘problem’ landscapes I drive by.

Well, not this time!  I was so distracted by the beauty around me that I didn’t notice any landscape mistakes.

I hope you enjoy them as much as I do and are inspired to create your own!

 
Valentine bush (Eremophila maculata ‘Valentine’) is hands down, my favorite shrub.  I love its bright red color, which decorates the landscape from January through April.  Even when not in bloom, the foliage looks lovely.
 
Golden barrel cacti (Echinocactus grusonii) with their sunny yellow color are a great choice. I use them often in my landscape designs due to their drought tolerance, low maintenance (they need none) and the yellow color they add throughout the year.
 
Large desert spoon (Dasylirion wheeleri) add great contrast with their spiky texture and gray-blue coloring.
 
This is a great pairing of plants that I plan on using in future designs.
 
 
The yellow, fragrant flowers of feathery cassia (Senna artemisioides) are famous for their winter color. Nothing else brightens a dreary winter’s day as much as the color yellow. The silvery foliage of this cassia adds great color contrast and give off a silvery glow on a breezy day.

In the background, you see the pink blooms of pink fairy duster (Calliandra eriophylla). Their uniquely shaped blooms look like a feather duster and hummingbirds find them irresistible. 

Bursage (Ambrosia deltoidea) is a native groundcover that needs little water and provides nice color contrast.

 
This combination was well done but planted too closely together.
 
Against the backdrop of yellow-flowering feathery cassia, a pair of boulders are decorated with blue bells (Eremophila hygrophana). These shrubs have lovely gray foliage and produce purple/blue flowers all year long.  This is a newer plant introduction getting a lot of attention. 
 
A golden barrel cactus offers great contrast along with a pair of agave.
 
 
Here is one of my favorite landscapes in this particular community.  I like the combination of cacti, flowering shrubs, and perennials that create a pleasing landscape.
 
A trio of flowering firecracker penstemon (Penstemon eatoni) easily catches your eye. They are one of my favorite perennials in my own garden and flower January through April in the low desert.
 
 
In another landscape, firecracker penstemon is used as part of a wildflower planting, backed by desert spoon and purple trailing lantana.
 
 
Ornamental grasses add great interest to the winter landscape and pink muhly (Muhlenbergia capillaris) is one of my favorites. Their burgundy plumes, which appear in fall fade to an attractive wheat color in winter. Soon, they will be pruned back to 3 inches in preparation for a new growth cycle.
 
 
Some landscapes look attractive using a minimum amount of plants.  The key is to use a variety of different plants – not just shrubs or cacti.  In this one, a blue palo verde (Parkinsonia florida) overlooks a planting of purple trailing lantana (Lantana montevidensis) and desert spoon.  While the lantana is frost tender, the canopy of the tree provides it some protection from frost.
 
 
It’s important to anchor the corners in your landscape – particularly those next to the driveway. Here is an example of how to combine plants that look great throughout the year. When warmer temps arrive  ‘New Gold’ lantana (Lantana ‘New Gold’), bursts forth with colorful blooms that last until the first frost. In winter, golden barrel cacti attract the attention and keep you from noticing the frost damaged lantana. 
 
 
This street planting also attracted my attention with the row of little leaf (foothill) palo verde (Parkinsonia microphylla) trees, Valentine shrubs and purple trailing lantana. I should note that lantana doesn’t usually flower much in winter, but in mild winters, they do.

An almost leafless mesquite tree stands sentinel over a planting of red-flowering chuparosa (Justicia californica). This shrub has lovely green foliage and tubular flowers that drive hummingbirds crazy with delight.

As you can see, the Southwestern landscape is filled with beauty and color, even in winter.  Unfortunately, many homeowners only use plants that bloom spring through summer. This leaves them with a boring landscape through the winter months for several months. So, celebrate the winter season by adding a few of these cool-season beauties to your garden!

 Got brown and crispy plants? Put down your pruners if winter has not ended yet! 

Are you having a hard time ignoring them the ugliness of the frost-damaged leaves? Or perhaps you have no problem with some brown spots in your garden.  

There has been some discussion on my social media pages from people asking if they can safely prune back their plants now and I know that some of you are just itching to get outside with either your hedge-trimmers, loppers or hand pruners. 

Well, before you pick up your pruning tool of choice – I have some important advice for you.

DON’T!!!
Okay, was that obvious enough? You may be asking why you can’t go outside and prune away that brown ugly stuff in your garden.
 
Well, the answer is that you can eventually prune it away, just not now.

There are three very good reasons not to prune back your frost-damaged plants during the winter.

1. Oftentimes, the brown, dead looking branches are not dead on the inside. The warm temperatures of spring will stimulate new growth in much of the dead-looking branches. If you prune your plants too early, you may be removing live branches.
 
 New growth in March.
 2.  In general, pruning stimulates plants to produce new growth. Many gardeners make the mistake of pruning too early before the threat of cold temperatures has passed and then a period of freezing temperatures occurs, which not only kills the new growth but can even result in the death of your plant.
 
3.  The brown and crispy stuff actually protects the interior and sometimes the lower foliage of your plant from further cold damage.
 

So, I hope these reasons help to convince you to turn a blind eye to your brown and crispy plants for a little while.

Once the threat of frost is over, you can go ahead and prune away to your heart’s content 🙂
 
But, beware of giving in to the temptation to start pruning a little early.  You never know when a late frost will hit. Sometimes just when you think that there is nothing but warm weather ahead, a late frost can sneak up on you.  If you aren’t sure you can keep yourself from pruning your plants too early, ask someone you trust to lock up your pruners until the threat of frost is over 😉
 
geraniums in Arizona garden

Salmon-colored geraniums

I learned this lesson the hard way. Years ago, I was in charge of decorating with plants for a large event. I purchased 100 potted geraniums and arranged them expertly with my crew in late February. The night before the event, we had a late frost that damaged every single geranium and we have to rapidly replace them. I should have used a plant that was more cold hardy.

So, maybe you can’t stand having frost-damaged plants in your garden anymore. If that is the case, I have an assignment for you…..

Take a drive through your neighborhood and those close by as well.  Look at your neighbor’s front landscapes and see what plants are still green and did not suffer any frost-damage.

The yucca, desert spoon, and pygmy date palm all did well while the trailing lantana did not.

 The ficus tree fared poorly while the tipu tree did well.

When looking around, you will find exceptions. Some plants that normally would suffer frost damage look healthy and green.

 

As you can see, there is a large blue palo verde tree with a ‘Torch Glow’ bougainvillea underneath to the right.  You may note that this bougainvillea did not suffer frost damage.

Why?
The overhanging branches of the palo verde tree provided some protection from the cold temperatures.  
 
This knowledge can be quite helpful to you if you like having frost-tender plants in your garden but don’t like the brown and crispy winter look. By placing plants such as lantana and bougainvillea underneath a tree with filtered shade, you can oftentimes skip the ugly, winter stage.
pruning plants
Before you know it, winter will have passed and you can grab your pruners and get busy in the garden!
