violet silverleaf (Leucophyllum candid)

At first glance, violet Silverleaf (Leucophyllum candid) may look like a nice gray shrub with a smattering of purple flowers.

BUT, when you crank up the humidity and add some summer rain into the mix and it really explodes with color…

purple beauty

These shrubs literally stop people in their tracks with their purple beauty.

(Leucophyllum candid) is easy to grow in arid climates and when not in flower, its gray foliage provides great color contrast in the landscape.

Fall planting

Fall planting

It’s hard to believe that we have made it through another summer.    

Oh, I realize that we have a few more weeks of 100+ degree weather, but whenever there is month that ends with the letters “ber” it just feels cooler to me.  

I am gearing up for my favorite season in the garden.  In my last post, I talked about the reasons why fall is the best time to add new plants to the Southwest landscape.    

Today, I’d like to share with you three tips to help you make the most of your fall planting.

This planting hole is too small

Photo: This planting hole is too small.

It all comes down to the hole.  It’s hard to believe that often what determines a plant’s initial success is the size of the hole it is planted in.  

If you are digging holes like the one above – then you may be in trouble.  That hole is too narrow.

Fall Planting

The ideal hole should be 3X as wide as the root ball.    

Why?  

Well, most of a plant’s roots grow outward into the soil.  When they are placed in a hole like the one above, the recently loosened soil makes it much easier for roots to grow into, which helps the plant to establish much sooner.  

*It’s important to note that the depth of the hole should be the same depth as the root ball or even a few inches shallower.  This helps prevent problems from the dirt settling, which can leave your new plant sitting rather low in the soil where problems with becoming waterlogged can happen.

Fall Planting

The big question – whether to add soil amendments or not?

When you go to your local nursery to buy new plants, you may be encouraged to buy soil amendments such as compost, potting soil or even manure.

The question is, do you really need it?  Often you don’t.    

I have planted thousands of plants throughout my career as a horticulturist and most of them without adding anything to the soil.  The plants were healthy and did very well without any extra additions to the soil.  

Here a few guidelines to follow to help you decide whether or not to add any amendments to the soil before planting.  

– If your soil is well-drained AND your new plants are native to any of the desert regions of the United States, than the answer is “no”.    

Native plants are adapted to growing in the nutrient poor soils of the desert and do best when nothing is added to the soil.  In fact, if the soil is too fertile – you’ll often see green growth, but flowering will be decreased.

Photo: Valentine (Eremophila maculata), Feathery Cassia (Senna artemisoides) and Purple Trailing Lantana (Lantana montevidensis) planted without needing any soil amendments.

The same can be said of some non-native plants – particularly those from Australia such as Eremophila and Senna species.  

So, are some times when adding soil amendments is a good idea?  

Absolutely!  

– If you have heavy clay soil or very sandy soils, than adding compost to the planting hole can help.  Mixing compost in with clay soils help them to drain better.  This is important because most plants that grow in the Southwest do best in well-drained soil.  

Conversely, sandy soils have a hard time holding onto enough water, so compost helps those soils to hold onto more water.   Add 1 part compost to 1 part native soil and mix together before planting.

require fertile soil to grow their best.

– Amend the soil when planting non-native plants that do not originate from arid climates.  

Plants like day lilies, iris, roses, etc. require fertile soil to grow their best.  Amending the soil with compost, manure and other amendments will improve the soil texture, add small levels of nutrients and add beneficial microorganisms which will benefit your plants.    

Plants such as these will need regular applications of fertilizer to do their best.  

Personally, I like to grow what I like to call ‘fuss-free’ plants where I don’t have to add fertilizer with the exception of my roses.  

Fall Planting

Skip the fertilizer for newly planted plants.  This tip is NOT always popular with some nurseries who often encourage the application of fertilizer at the time of planting.  

So, let’s talk about when to add fertilizer.  

– Most native plants will not need fertilizer ever.  In fact, many can make their own fertilizer.  

– For plants that do need fertilizer such as hibiscus,  iris, roses, etc. – wait until you see new growth occurring before adding fertilizer.  

The reason for this is that when you first add a new plant, it needs to concentrate on growing new roots in order to support future top growth (stems, branches and leaves).  If you add fertilizer at the time of planting, you are forcing the plant to focus on the top growth before it has the roots to support it.

So, a general rule is to wait until you see new top growth before adding fertilizer.  

– The rule for fruit trees is slightly different.  It is recommended to wait until 1 year after planting before fertilizing.  

Again, you may hear differently from your nursery who in addition to wanting you to be happy with your purchase, also has their bottom line (profits) in mind.  

I am not including all nurseries or nursery professionals into this one group.  However, I have visited nurseries where customers are told that they need to fertilize all their plants.  Many of my clients are thrilled when I tell them to throw out their fertilizer because their native plants don’t need it.  

*I remember a story from one of my horticulture professors who talked about standing in line behind a customer at the store with a cart filled with native, desert plants and another cart with ‘special’ fertilizers that they were encouraged to buy.

My professor loudly commented to her husband, standing next to her, that “Numerous studies have shown that fertilizer is a waste of money when used for native plants.”    

So, are you ready to add some new plants to your landscape?   Before you head out to the nursery, I invite you to come back for my next post, when I’ll share with you some tips on how to select healthy plants AND I will reveal to you what my favorite plant nursery is!  

************************  

I apologize for the relative lack of recent posts.  Life has been very busy with the kids back in school, increased landscape consults and getting ready to go visit my daughter, Rachele, who is expecting.  We will find in a few days whether we will be welcoming a boy or girl!  

I have two biological children – both girls and my oldest daughter, Brittney, has a daughter.  So, we will see if Rachele will break the pink trend in our family.  

My son Kai (who is adopted from China) and has four sisters and a niece is really hoping for a boy 😉

Planting in fall

Planting in fall

Are you anxious for fall to arrive?  

I certainly am!    

Fall is my favorite season because of the holidays, cooler weather, and best of all – it is the best time of year to add new plants to the landscape.

Planting in fall

Now you may have thought that spring was the best time of year to start planting and while you certainly can plant then, I’ll tell you why fall is better…

Planting in fall allows enough time for plants to grow a good root system before the heat of the next summer arrives.  

Think about it – plants must have a good root system so that they can soak up enough water to handle the stress from intense heat and the dry conditions of summer.    

If a plant is planted just before or during the summer months, they are focused on just hanging on until temperatures cool off.  In many cases, they don’t make it.

fall planting

The only exception to fall planting is with frost-tender plants such as bougainvillea, lantana, and yellow bells.    

Because young plants are particularly susceptible to frost damage, or even death, it is best to wait until the danger of frost has passed to add these plants to your landscape.

Getting Ready for Fall Planting in the Southwest Garden

Over the next couple of posts, I’ll share with you some other helpful tips to help you with selecting plants, how to tell if they are healthy, the best way to dig a hole, and finally – I’ll reveal my favorite plant nursery!

On a personal note, I am going to be a grandma again 🙂  

My second-oldest daughter, Rachele, is having her first baby, and my husband and I are flying to California to be there when she gets her ultrasound and finds out if she is having a boy or girl!

New Perennial Discovery and a Baby

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

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

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

Agave parryi in Southwestern landscape

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

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

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

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

Flourishing Amidst Adversity: 10 Resilient Plants in the Southwestern Landscape

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

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

Embracing the Sun: Essential Care Tips for Desert Native Plants

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

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

With adaptations that defy the elements, these species contribute to the intricate web of life in the desert, adding splashes of color and life to the arid landscape.

By embracing these resilient beauties, gardeners can cultivate oases of natural wonder in even the most unforgiving of terrains.

Tour of Sustainable Southwestern Landscape: Part 1

Have you ever had a ‘substitute’ teacher?  As most of you know, a substitute teacher doesn’t do things the same way our regular teacher does.

A few years ago, I was asked to step in as a ‘substitute’ gardener for my father-in-law’s landscape.

Meticulously pruned desert ruellia (Ruellia peninsularis)

Photo: Meticulously pruned desert ruellia (Ruellia peninsularis)

My father-in-law had always been a meticulous gardener and took a lot of pride in his landscape. Have you ever seen rounder shrubs?

A few years earlier, I had designed the landscape around his new home and tried to convince him to allow his plants to grow into their natural shapes. But as you can see from the photo above, he didn’t follow my advice.  

He eventually took out his backyard grass and replaced it with artificial turf and whenever flowers or leaves would fall on the grass, he would vacuum them up – I’m not kidding.  

We would often joke with each other about our very different styles of gardening – especially when he would come over to my house for a visit and see my plants growing “wild and free” as he would say.    

But despite our differences, we shared the same love for plants and the garden.  

Unfortunately, his gardening days were numbered and he asked me to come over and help him with the gardening tasks that he could no longer do.  

My father-in-law was diagnosed with ALS (Lou Gehrig’s disease) in October 2010 and it progressed very rapidly.  

So, I became his ‘substitute gardener’ and I was happy to be able to help out so that he could still enjoy the beauty of his garden, even if he could not care for it himself.

gold lantana

In early August of 2011, I lightly pruned back his gold lantana.  At this point, my father-in-law spent most of his time indoors sitting down. But, as I was pruning, I saw him slowly make his way out, with his walker, so he could watch me prune his plants.  

At this point, he could no longer talk due to ALS and I’m certain that if he could have spoken, he might have asked me to make the lantana ’rounder’.

After this light pruning, the lantana would grow back to its original size before stopping during winter.  If they had not been pruned, they would have look quite overgrown for my father-in-law’s taste.  

Light pruning involves removing 1/3 or less.  The timing of this light pruning is crucial – prune too late and your plants will be extra susceptible to damage from frost.  Don’t prune after early August in zone 9 (July in zone 8) gardens. Pruning in fall should not be done for this very reason.

Substitute Gardener

Substitute Gardener

Another part of the garden that my father-in-law took a lot of pride in was his flowering annuals.  Every year, he would plant the same red geraniums and white-flowering bacopa in winter.  Once spring rolled around, he would plant red and white vinca. He never deviated by trying out newer colors or varieties.  

I found myself taking over this job as well and when I came home and see all there was to do in my neglected garden – I didn’t mind.  It felt so good to be able to control how his garden looked because ALS had taken control of everything else.  

My father-in-law died in September 2011, just 11 months after being diagnosed with ALS.    

It’s been almost 3 years since he passed away, but whenever August comes around and I find myself lightly pruning back my gold lantana – I enjoy the memory of one our last moments together in the garden as I pruned his lantana.

Pruning Flowering Shrubs in Late Summer

There are some plants in the landscape that are underused through not fault of their own.

This can be for a number of reasons, one of which, is that it isn’t stocked at local nurseries.  Customers often walk into their local nursery without any specific plant in mind and choose from what is in stock.

nursery container

Another reason is that many southwestern natives aren’t all that impressive looking in their nursery container, where their root growth is restricted.   However once they are planted and roots begin growing, they really take off and transform into a beautiful plant.

 little leaf cordia

One underused plant in the southwest garden is little leaf cordia (Cordia parvifolia).  

There are so many reasons to love this underused, native shrub…  

– it is evergreen in zones 8 and above

– thrives in areas with full, reflected sun

– is drought tolerant

– needs no fertilizer

– rarely needs to be pruned

– and perhaps most importantly, it has beautiful, white flowers!

 little leaf cordia

I recently wrote about little leaf cordia for Houzz.com and how to grow and use it in the landscape.  

My hope that this underused shrub will soon become a much-used shrub in the southwestern landscape.

Downsizing Is A Good Thing – But Not Always….

Have you ever seen shrubs that have been planted too closely together?

overcrowded shrubs

At first glance, it looks like the new plants in the landscape above fit just fine into this area.  

But, what if I told you that those small shrubs grow 6 feet high and wide at maturity?

overcrowded shrubs

As they grow, out come the hedge trimmers, and over-pruned, ugly shrubs are the result.  

Unfortunately, this is a problem that has reached almost epidemic proportions in areas throughout the Southwest.  

Why else would people prune beautiful flowering shrubs into something that resembles anonymous, green blobs?  

The good news is that you can avoid this from happening in your landscape.  Even if you currently have overcrowded shrubs, you can solve the problem.

I recently wrote an article for Houzz.com on how to avoid overcrowded and the resulting over-pruning…

10 Tips for Drought Tolerant Gardening

Do you like red yucca (Hesperaloe parvifolia)?

red yucca (Hesperaloe parvifolia)

Landscapes throughout the desert southwest come alive in spring and early summer as the coral-colored blooms of red yucca burst forth.

There are a few reasons that this succulent is a popular plant.

For one, its grass-like foliage add texture to the garden, even when not in flower.

Second, it needs little maintenance – simply prune off the flowers when they fade.

red yucca

The flowers are quite beautiful.

While the most common flower color for this fuss-free plant is coral, there are two other colors that I would like to introduce you to.  

Hesperaloe parvifolia

While not a new color, there is a yellow variety of “Hesperaloe parviflora” available.

It is the same as regular red yucca, except for the color.

Imagine the creamy yellow flowers against a dark-painted wall such as brown, green or purple?

Gorgeous!

Here is a color of “Hesperaloe parviflora” that is relatively new…  

Brakelights

This is a new variety of red yucca called ‘Brakelights’.  Its flowers are a darker red than the normal coral flowers.

I am always interested in different colored varieties of my favorite plants.  It is easy to add interest to your garden when people see a different color than they expect.

Have you ever made a discovery that was literally under your nose?  

I did.

Earlier this month, I embarked on a tour of low-water gardens that displayed sustainable design throughout the greater Phoenix area.  

The earlier parts of our tour showed examples of water harvesting using cisterns along with man-made arroyos.  Then we viewed a creative example of sustainable design for a beautiful parking lot that needed no supplemental water and little to no maintenance.

I mentioned last week that I had saved the best for last and I can’t wait to share with you this jewel in the midst of a desert city.

sustainable gardens

The last stop on our tour of low-water and sustainable gardens was the Scottsdale Xeriscape Demonstration Garden.

The garden is just over 5 acres and sits hidden from the street next to Chaparral Park in central Scottsdale.

Over 200 different types of plants are used throughout the garden, all of which are drought-tolerant and well-adapted to our hot, dry climate.

My friend and fellow blogger, Pam Penick, came with me to this beautiful garden (you can see her at the top of the terraced planters).

My friend and fellow blogger, Pam Penick, came with me to this beautiful garden (you can see her at the top of the terraced planters).

One of my favorite parts of the garden included this innovative design, called the ‘Terraced Cascade’ which creates the appearance of water traveling down between terraced planters filled with Palo Blanco trees (Acacia willardiana) and Desert Marigold (Baileya multiradiata).  

sustainable gardens

 Water does flow down discretely hidden steps between the terraces during times of heavy rainfall toward the water harvest basin where it waters existing plants before flowing underground toward the nearby lake.

Raised planters were filled with flowering Ocotillo  as well as Birdcage Evening Primrose (Oenothera deltoides).

I must admit that I was surprised to find this garden in an area that I used to spend a lot of time in.

Years ago, before the garden existed, my husband and I would take evening walks around the nearby lake with our daughter.  Believe it or not, before there was a garden, there used to be a miniature golf course in this location. 

sustainable gardens

I love stone walls and would have some in my own garden, if I could afford them.  The stone walls were capped with flagstone and had rows of round stones, which added an unexpected touch of texture.  

sustainable gardens

From our vantage point, we could see to the other side of the garden where a tall, dead tree stood.  Trees like this are called a ‘snag’, which is a dead or dying tree.  This tree provides a home for hawks, which help keep the rabbit population down. 

Baja Fairy Duster (Calliandra californica) and Desert Marigold (Baileya multiradiata)

Gabion walls were used along pathways to created terraces to help slow down storm water in order to reduce flooding while watering the plants.

The demonstration garden is located next to a water treatment plant and part of the garden sits on top of a reservoir that contains 5.5 million gallons of treated water.

Deer Grass in the foreground

One of the things that I enjoy about demonstration gardens is that they ‘demonstrate’ different gardening methods as well as showcasing plants.

In this case, I was impressed with the collection of plant species used, which aren’t typically seen in residential or commercial landscapes, which is a shame.

sustainable gardens

As we walked down the main path, we came upon a man-made, mesquite ‘bosque’.  The word ‘bosque’ is used to refer to stands of trees nearby rivers or washes throughout the southwestern United States.  Usually, you’ll find these bosques made up of mesquite trees.

This bosque was planted with Honey Mesquite trees (Prosopis glandulosa), which is simply stunning in spring when it’s bright-green leaves reappear.  A warning though – it has thorns.

The main pathway parallels the local dog park.

There is little that can compare to the beauty of the  new spring leaves of mesquite trees.  I love how the coral-colored variety of Bougainvillea and the yellow flowers of Aloe Vera look like brightly-colored jewels along with the leaves of the mesquite.

sustainable gardens

Nearing the end of the trail, I couldn’t help but marvel at this beautiful garden and its creative design.

Throughout the garden were educational signs talking about a myriad of gardening subjects that were clearly illustrated by the garden itself including planning and design, plant care and desert habitat.

sustainable gardens

A large cistern was located on one end of the trail, which was filled with the average amount of water that a household uses in 1 week.

Around the outer border of the cistern is an American Indian saying that says:

“THE FROG DOES NOT DRINK UP THE POND IN WHICH HE LIVES”

Those are words that all of us who live in the dry, southwest should all ponder…

The Scottsdale Xeriscape Demonstration Garden is located at Hayden and McDonald Roads in Scottsdale.  It is open from sunrise to 10:30 at night.

I hope you have enjoyed these posts of our tour of sustainable, southwestern landscapes in the greater Phoenix area.

Pam and I drove about 170 miles in one day and we weren’t able to see all of the great examples of sustainable landscaping.  However, if you are interested in seeing examples of sustainable gardening, then I would recommend starting at the Desert Botanical Garden, which is filled with arid-adapted plants that thrive in our climate with minimal water and fuss.

If you haven’t visited Pam’s blog, Digging, I encourage you to do so.  Many of the plants that she grows in Austin do well in our climate too.  Did I also mention that she is an author?  She has a fabulous book called Lawn Gone!: Low-Maintenance, Sustainable, Attractive Alternatives for Your Yard, which I highly recommend.
