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.

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…

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.

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

Here are just a few reasons why…

  • It removes the leaves needed for the shrub to make energy for itself
  • Excessive pruning actually makes your shrubs grow faster, which equals MORE maintenance
  • Shrubs pruned often require more water as they constantly work to replace foliage lost
  • Continued shearing will shorten the lifespan of your shrubs
  • Green ‘blobs’ are ugly compared to beautiful flowering shrubs

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.

I absolutely love spring.  Some years, spring never arrives.  Sometimes spring goes missing and winter turns right into summer.  But not this year.  We have had beautiful weather and I have enjoyed being outdoors.  

But, all good things must come to an end.  Now don’t get me wrong.  I do like the summer, but you will find me inside much more often then outside.  Sometimes I wonder if some of my plants would rather be inside enjoying the air-conditioning.

Did you know that May and June are the most stressful months for plants in the desert southwest?  Well, it is.  Although the hot summer temperatures cool down in the evening, the daytime heat coupled with the extreme dryness of our climate is quite stressful for plants.  When the monsoon season arrives in July, the increased humidity and rain bring relief to the plants.

So, what is a plant to do when it cannot escape indoors from the heat?  Well, I would love to show you one example of what some shrubs do to deal with the dry heat.

To really see what I am talking about, look closely at the photo below…

Can you see it?  Can you tell what helps to protect the flowers from the sun?  

Hint: Look at the little hairs on the petals.

love spring

Texas Sage (Leucophyllum frutescens) and all other Leucophyllum species have tiny hairs on their flowers, stems and their leaves, which help to deflect the sun’s rays and helps to reduce the amount of water lost to the air. It is these tiny hairs that give the leaves a gray-green color.

Drive down any street in the Desert Southwest and you will see these beautiful shrubs throughout the residential landscape.

love spring

Even though I have worked as a horticulturist for over 10 years, I am still amazed at how plants adapt to their environment. 

By the way, you may be thinking that I took these close-up photos to show the tiny hairs covering the blossoms, but actually, my goal was to show how beautiful the flower was. It was only after I downloaded the pictures that I saw the tiny hairs.  

It makes you wonder what else you may find just by taking close-up pictures of plants….

Do you ever wish you had flowers to give to a friend or to decorate your table?

Instead of heading to the store for a generic bouquet, how about creating a lovely bouquet straight from your garden?

Now before you say that you don’t have any flowers suitable for a bouquet, think again.  

Here are several bouquets from my garden and a few that my mother put together from her own garden….

gold lantana(Lantana 'New Gold Mound'), orange jubilee(Tecoma x Orange Jubilee) and Texas sage(Leucophyllum frutescens)

Isn’t this a lovely arrangement?

Believe it or not, the flowers in these vases all came from plants that many of you probably have in your own garden.

My mother created this arrangement using gold lantana (Lantana ‘New Gold Mound’), orange jubilee (Tecoma x Orange Jubilee) and Texas sage (Leucophyllum frutescens) flowers.  As you can see, it is beautiful, didn’t cost her anything and took minutes to create.

 Pink and white globe mallow (Sphaeralcea ambigua) , Goodding's verbena (Glandularia gooddingii)

This is a bouquet that I created using flowers from my late winter garden. Pink and white globe mallow (Sphaeralcea ambigua) coupled with Goodding’s verbena (Glandularia gooddingii) are a vision of pinks and purples.

purple trailing lantana (Lantana montevidensis), angelita daisy (Tetraneuris acaulis) and flowers from my cascalote tree (Caesalpinia cacalaco).

I used a small pitcher to put cuttings of purple trailing lantana (Lantana montevidensis), angelita daisy (Tetraneuris acaulis) and flowers from my cascalote tree (Caesalpinia cacalaco).

 white alyssum (Lobularia maritima) , purple violas and pink bower vine (Pandorea jasminoides)flowers.

This antique milk of magnesia glass jar makes the perfect vase for sweet white alyssum (Lobularia maritima) , purple violas and pink bower vine (Pandorea jasminoides) flowers.

Flowers aren’t the only thing from the garden that you can use to create a bouquet with.

A mason jar filled with cut branches from a kumquat tree looks lovely on this table in winter.

Maybe your winter garden has no flowers.  Well, don’t let that stop you. A small vase filled with seedpods and dried leaves from a Texas mountain laurel (Sophora secundiflora) looks great on my mother’s diningroom table.

Perhaps you’ve never thought that petunias could look be used in a vase. But, if you use a small, shallow bowl, they can add a beautiful spot of color on your table.

Of course, roses always make a lovely bouquet.

Bouquets created from items in your garden are a great way to add a personal touch of beauty to your space.

So, are you inspired to create your own unique garden bouquet? Step outside in your garden and take a new look at your plants – you’ll probably be surprised at how many would look nice in a vase.

Landscape No-No

Photo: Landscape No-No

Have you ever driven past a landscape that had some problems with it?  As a horticulturist and landscape consultant, my attention diverts whenever I see ‘Landscape No-No’s’ like this one.

Awhile ago, I shared the photo of the landscape, above, on my Facebook page and invited people to identify three things wrong with the landscape.  I received a lot of comments including “looks like Versailles by the inept” and “shrubs arranged like funny looking ottomans spread across gravel.”  

It’s important to not that my reasons for showing examples like this aren’t to shame the homeowners. Instead, my goal is to help others to learn to identify problems and give them easy steps to correct or avoid them in the first place.

So, using this landscape as an example, let’s look at the problems and later, focus on how to solve them:

shrubs pruned the wrong way

1. Shrubs are planted too closely together.  

It’s obvious that there are too many plants in this area and the mature size of the shrubs wasn’t factored in the original design.  The types of flowering shrubs in this area – desert ruellia (Ruellia peninsularis),  Baja fairy duster (Calliandra californica), and ‘Green Cloud’ sage (Leucophyllum frutescens ‘Green Cloud’) are good choices. The problem is that they are spaced too closely together and pruned the wrong way.

2. Lack of different plant types. 

As you can see, there is a tree, a couple of succulents (prickly pear cactus & yucca), and a LOT of shrubs.  However, the landscape suffers from an overabundance of shrubs.  

3. Incorrectly pruned flowering shrubs. 

These lovely, flowering shrubs have been turned into anonymous, green blobs, lacking in beauty and character.  In fact, you would have to look closely to be able to identify what each shrub is.  The problem has to do with what is missing from this landscape, which are attractive shrubs allowed to grow into their natural shapes, covered in colorful flowers.  Other problems associated with maintaining flowering shrubs this way is that it is stressful for the plant, shortens their lifespan, causes to them to use more water to regrow their leaves, and creates more maintenance.

Now that we have identified the problems, we can now look at the solutions.  I will use the landscape above as my example:

landscape-no-no-badly-pruned-shrubs
  • Remove excess shrubs.  Take out 24 of the existing 32 shrubs so that you are left with eight flowering shrubs.  To decide what shrubs to remove, learn what type of shrub they are and look up how large they are at maturity.  Then, make sure that the ones that remain have enough room to grow.  Shrubs should be places up near the house, to anchor the corners of the landscape, and flank an entry.
  • Severely prune back remaining shrubs.  One of the things I love about shrubs is that quite a few have a ‘restart button’ where much of the damage that has been done due to excessive pruning can be reversed.  Severe renewal pruning entails pruning back shrubs to approximately 1 1/2 feet tall and wide in spring. You’ll have nothing left but woody branches and little to no leaves.  However, this stimulates plants to produce new, healthy growth. This type of pruning should be done in spring.  The key is to keep hedge trimmers away from your newly pruned shrubs forever. Any pruning should be done using hand pruners, loppers, and pruning saws.  This will work with most shrubs except for a few that were in declining health.

  • Incorporate lower-growing plants such as groundcovers and succulents. A well-designed landscape has plants with varying heights, including those at ground level.  For the landscape above, I’d add a few boulders and plant some gopher plant (Euphorbia rigida) and twin-flower agave (Agave geminiflora) alongside them.  Other ideas for low-growing succulents include ‘Blue Elf’ aloe, Moroccan mound, and artichoke agave.  Flowering groundcovers would also look nice like angelita daisy (Tetraneuris acaulis), blackfoot daisy (Melampodium leucanthum), and sandpaper verbena (Glandularia rigida).  I like to use damianita, trailing lantana, and penstemon for color at lower heights.

Photo: Attractive desert landscape with room for plants to grow

Here is a snapshot of a landscape area at the Desert Botanical Garden where plants have room to grow and are allowed to grow into their natural shape and form.

Transforming the problematic landscape shown earlier, and others like it isn’t difficult, and the results are dramatic.  What you are left with is a beautiful landscape filled with healthy plants that use less water and needs little maintenance.

If you are tired of shapeless shrubs shaped like green blobs, I invite you to learn more about how to prune ‘right’ way in my online Shrub Pruning Workshop.

Overgrown plant , old Texas sage (Leucophyllum frutescens 'Green Cloud')

Overgrown plant, old Texas sage (Leucophyllum frutescens ‘Green Cloud’)

You have undoubtedly seen an old, overgrown plants filled with mostly leafless branches that rarely flower anymore. Or, perhaps it is an aged succulent that has brown patches that are slowly encroaching onto the upper parts of the plant from the base. So, what is the solution for plants that no longer add decorative value to our landscape?

While some woody plants such as Texas sage or oleander can be rejuvenated by severely pruning them back, not all plants respond favorably to this and grow out again. Let’s take a look at some Southwestern favorite shrubs and succulents and talk about whether you should prune severely or when it’s best to replace.

Overgrown plant , Oleander that has undergone severe renewal pruning in spring

Oleander that has undergone severe renewal pruning in spring.

Many shrubs can be rejuvenated by severely pruning them back, which gets rid of old, woody growth and stimulates the production of new branches, which will flower more (in the case of flowering shrubs). It is helpful to think of severe renewal pruning as the “fountain of youth” for many plants. This type of pruning is best done in spring, once the weather begins to warm up. Shrubs that respond well to this include bougainvillea, jojoba, lantana, oleander, Texas sage, and yellow bells. It’s important to note that not all shrubs will come back from this method, but the pruning didn’t kill the shrub – it only hastened the demise of the plant that was already in progress. If this happens, replace it with another.

Old desert spoon (Dasylirion wheeleri)

There are some plants that don’t respond well to renewal pruning or where that isn’t possible to do in the case of succulents. In this case, the solution is simple – take them out and replace them with a younger version of the same plant. Examples of plants that are better removed and replaced include aloe, desert spoon, red yucca (hesperaloe), rosemary, and prickly pear cactus. When you think about it, the cost isn’t very high, when you consider the beauty that these plants added to your landscape for eight years or more.

When you think about it, the cost isn’t very high, when you consider the beauty that these plants added to your landscape for eight years or more.

*Have you severely pruned back an old shrub and had it come back beautifully? Or, maybe you recently removed and replaced some old succulents?

Ready to Prune? Here Are Common Pruning Terms Defined

Do you ever find yourself pulling into the drive-thru of a fast food restaurant?

I do.

Lately, I have been very busy with landscape consults as well as working on a large golf course re-landscaping project, which have resulted in more than my share of visits to the local drive-thru.  Add to that my preparations for a local craft fair in November (along with my sister and mom where I am making basil salt, seed bombs and air plants mounted on creosote roots), preparations for an upcoming family reunion as well as hosting my daughter’s baby shower – we will probably be making quite a few more visits to the drive-thru.

Normally, drive-thru restaurants are places where you can see examples of poor design showcasing overplanted and over pruned shrubs that are too large for the narrow landscape spaces by the drive-thru lane.  However, I was truly surprised during one trip through at my local fast food restaurant.

First, let’s look at the landscaping you normally find as you visit the drive-thru…

drive-thru landscapes

Over pruned feathery cassia shrubs (Senna artemisioides)

These shrubs would actually work well in this space if you reduced the amount down to three and allowed them to grow to their natural size and form…

Feathery cassia in bloom

Do you think that those overpruned shrubs ever have any flowers appearing in late winter and spring, like this one?

I didn’t think so.

drive-thru landscapes

In the Southwest, the types of shrubs that you are most likely to see growing along drive-thru landscapes are oleander and Texas sage species.

Lately, Valentine bush, which is one of my favorite shrubs, has also been showing up more often in these areas.

Again, the problem is too many plants in not enough space.  Couple that with the compulsive need to strip the natural beauty from these beautiful, flowering shrubs in an attempt to create anonymous green shapes and you have the perfect scenario for drive-thru landscapes.

With so many bad examples of landscaping while visiting the drive-thru, I must admit that I’ve become somewhat de-sensitized and purposely ignore it.

However, a recent visit to the drive-thru made me take a second look as I drove past this…

drive-thru landscapes

Notice anything different?

The plants actually fit into this space and without over pruning!

There is room for the bougainvillea against the wall to grow and while the lantana could use a little more room – it is looking great too.

What I really liked about this landscape was the use of banana yucca.  Its leaves added great spiky texture and the flowers are just lovely.

*I did notice the overpruned dwarf oleanders in the background, but I’m ignoring them.

Using fewer shrubs and allowing them room to grow is a great start to rethinking the drive-thru landscape.

The next important part is to stop the frequent pruning of flowering shrubs.

I’d love to see a mix of shrubs and succulents in drive-thru landscapes for more interest, less maintenance and that is more water efficient.

For now, I will keep trying to keep my eyes open for another great example of a drive-thru landscape.

But, I think it may be awhile…

I love the color purple in the garden because the color, helps to visually ‘cool’ the garden.

'Rio Bravo' Sage (Leucophyllum langmaniae 'Rio Bravo')

‘Rio Bravo’ Sage (Leucophyllum langmaniae ‘Rio Bravo’) 

Have you ever wondered how some plants handle our hot temperatures and intense sunlight?

Look carefully at the flowers, above.  Note the small hairs covering the petals?  They help to reflect the sun’s rays.

sage shrubs

I like using large shrubs to screen the back wall of my garden, so I have quite a few ‘Rio Bravo’ sage shrubs.

They put on a spectacular show off and on throughout the summer when they bloom.  (Leucophyllum langmaniae) is just one species of Leucophyllum (Texas Sage).

Of course, if you insist on pruning your sage shrubs into round ‘blobs’ – you will never see the flower show.

Believe it or not, these are the same type of shrub.

Did you know that over-pruning causes a lot of problems in the landscape that affect the shrub, water usage and your wallet?

I was recently asked to write an article for the folks at Water Use It Wisely, which is a water conservation campaign created by cities in the greater Phoenix metro area.

The article I wrote talks about the specific problems that over-pruning causes along with ways to avoid over-pruning.

A sustainable, low-maintenance landscape is not only beautiful, it can save the use of unneeded resources such as maintenance, time and money.

To date, our series on sustainable landscaping has talked about what is a sustainable landscape.  Next, we talked about what often goes wrong in the landscape that causes us to use unneeded resources.  

In our quest toward a more sustainable landscape, we started to discuss small steps that you can take towards a more sustainable garden.  In part one, we covered plant selection and what types of plants to avoid as our journey toward a sustainable landscape progresses.

Today, we will finish up our series on sustainable landscaping with additional steps you can implement in your garden right now.

Reduce over-crowded landscapes by removing excess plants.

sustainable landscaping

As you can see, there are far too many shrubs in this area, which helps to contribute to over-pruning.

To help solve this problem, simply remove the excess shrubs.  How can you tell which ones to remove?  First, find out what type of shrubs they are – in this case they are ‘Green Cloud’ Texas Sage (Leucophyllum frutescens ‘Green Cloud’).

Then use one of the resources I gave you last time to research the plant, which would tell you that this type of shrub will grow about 6 feet high and wide. So, the shrubs should be placed at least 6 feet apart.  

Using the photo above as an example, start out with the first shrub on the left, measure out to the next shrub that is at least 6 feet away.  Any shrubs between these two shrubs need to be taken out.  Repeat the process until the remaining shrubs are at least 6 feet apart.

Stop unnecessary pruning.

sustainable landscaping

These shrubs have plenty of room to grow in the landscape, yet they are pruned every couple of months.

This type of pruning is called ‘poodle’ or ‘cupcake’ pruning.

It is really quite amazing how much more work over-pruning causes and in ways you may be surprised to discover, click here to learn more. To reduce the amount of resources (green waste, water, plant replacement, and maintenance bills) wasted on unneeded pruning.

So declare your landscape a ‘poodle’ and ‘cupcake’-free zone.  Believe me, your plants will thank you for it and your plants will look much nicer.


Allow shrubs to grow to their natural size.

sustainable landscaping

When you allow enough room for plants to grow, the temptation to over-prune is greatly lessened.

Plants have a lovely shape that we frequently ruin, by making them into ‘balls’ or other unnatural shapes.  This does not only affect the health of the plant, it can also remove flowers.

Note: I am not saying that all pruning is harmful.  Pruning done properly can be beneficial for plants.

So, what if you have a landscape filled with over-pruned shrubs.  What can you do to transform them into more naturally-shaped shrubs that are more sustainable? 


The answer is relatively simple and it does involve pruning…

over-pruned shrub

This over-pruned shrub is located in my neighborhood.  I cringe whenever I walk by it while walking our dogs.

It is seldom allowed to grow any leaves before the landscapers come just about every leaf off.  Frequent over-pruning has led to old, woody growth that is unproductive.  

The solution to transforming this shrub is called rejuvenation pruning, which entails pruning the shrub all the way back to 1 1/2 feet.  In most cases, this will stimulate attractive, new growth that you can allow to grow into their natural shape.

*I mention ‘in most cases’ because there is always a chance that the shrub will not recover from this type of pruning.  However when this happens, it is usually an indicator that the shrub was already declining and would not have lived long regardless of whether it was severely pruned or not.

Below, is an example from my own garden…

sustainable landscaping

On the left, you can see a sage shrub that has been allowed to grow into its natural shape, which is more sustainable then over-pruning.  In addition, I also get a lot of beautiful flowers.

Every 3 years of so, when the branches become woody and unproductive, I prune it back severely (in spring) and within 4 – 6 weeks, it is already growing new branches filled with attractive foliage.

Water your plants deeply and infrequently.

sustainable landscaping

Would you be surprised to discover that 80% of your water bill is used outdoors?  It’s true.

Would you also be shocked to discover that most of us over-water our plants?  In fact, more plant problems are caused by over-watering then under-watering.

So, why waste water, which is a precious resource in the western United States needlessly?

While you can have a landscape filled with desert-adapted plants that need no water, after established – your plants will look better if given some supplemental water.

For my own landscape – I water my shrubs and perennials once every 3 weeks in the winter months and it looks beautiful.

In the summer, I water every 7 – 10 days.  

The key is to water shrubs to a depth of 2 feet, perennials/groundcovers to 1 foot and trees to 3 feet.

So, how do you know how often to water?

There is excellent information available for the Phoenix metro area that you can access here.

For those of you who in other arid climates – check with your local extension office for watering guidelines.  

However, if that seems rather complicated, there is a new irrigation controller that does all the work for you.  All you have to do is enter your zip code, once the controller is installed and it will keep track of your local weather and water your plants only when they need it.  You can find out more about this Smart Irrigation Controller, here.

*For those of you who would like more information, I have written more extensively on landscape watering for desert gardens that you can access here.

Have you ever wondered how sustainable your landscape is?

What Keeps a Landscape From Being Sustainable?

Earlier this week, we began our series of posts on sustainable landscaping and talked about what a sustainable landscape is.  You can find the first post here.

Most of us like the idea of having an attractive landscape without wasting resources such as fertilizer, excessive pruning and water, time and gasoline unnecessarily.  But, oftentimes we do things in our gardens that create the need for additional resources.

Today, we will look at one of the major problems that I see which often goes wrong and prevents people from having sustainable landscapes.

MISTAKE #1:

Most people fail to take into consideration how large their new plants will grow.

For example:

Leucophyllum frutescens 'Green Cloud'

This young ‘Green Cloud’ Texas sage (Leucophyllum frutescens ‘Green Cloud’) measures roughly 1 foot high and wide.

But, just a few years after planting, it does grow quite a bit…  

'Rio Bravo'

This ‘Rio Bravo’ sage (Leucophyllum langmaniae ‘Rio Bravo’), which is similar in size to ‘Green Cloud’ Texas sage reaches sizes up to 8 feet tall and wide.

It’s hard to believe that such a small shrub can grow so much in just a few years time.

sustainable landscape

This trailing rosemary was initially quite small when planted next to this boulder.  However, the homeowner did not allow for the fact that the rosemary would grow and eventually ‘swallow’ the boulder.

sustainable landscape

This small ficus tree looks rather innocent, doesn’t it?  But, it is harboring a secret…

sustainable landscape

It will grow absolutely huge!

This ficus tree absolutely dwarfs this house.

The mistake of not allowing for the mature size of plants when planting, leads to…

MISTAKE #2:

Over-planting.

sustainable landscape

At first glance, there appears to be nothing wrong with this landscape area.  There are some larger dwarf oleanders in the background and nine young Texas sage shrubs.

But, do you think that the Texas sage shrubs will fit in this area once they start to grow toward their mature size of 6 – 8 feet?

I don’t think so.

Over-planting occurs when people don’t allow for the mature size of the plants.  Of course, new plants look rather small and somewhat straggly once first planted, which often leads to over-planting to make the new area look more attractive.

That is what happened to this area below…

sustainable landscape

Would you believe that the shrubs planted above are actually the same as those shown below?

sustainable landscape

It’s true.  The only difference is that in this space, the mature size of the shrubs was taken into account, so there was no over-planting taking place.

Think about how much less money and maintenance this area uses compared to the previous area?  There are fewer plants, less maintenance and it looks much nicer!

Mistakes #1 and 2 lead us to…

MISTAKE #3:

Excessive pruning.

sustainable landscape

So, what do you think people do if their plants are planted to closely together – they prune them…a lot!

Drive-thru’s are places that you can usually find over-planted landscapes.  The one above is filled with 2/3’s more plant material then is needed.

The over-pruned shrubs in the forefront are actually Valentine (Eremophila maculata ‘Valentine’) shrubs, which look much more attractive when not over-pruned.

sustainable landscape

There are 3 Valentine shrubs in the photo above that are allowed to grow to their natural shape after their annual pruning in May.

sustainable landscape

These silver sage shrubs at our local Costco store have also been over-pruned due to the fact that they were planted too closely together.

Over-pruning often leads to artistic expressions…

'Abstract Art'

sage shrubs

Words fail me attempting to describe the pruning  of these sage shrubs.

Here are some interesting facts about over-pruning that you may be surprised to hear.

Over-pruning…

– makes plants grow faster (as they attempt to re-grow the leaves lost)

-creates more maintenance (faster growing plants tend to be pruned more often)

– uses more water (in their attempt to re-grow lost leaves pruned away).

– creates green waste (branches/leaves head to the landfill)

– leads to unhealthy plants (from the stresses of too much pruning).- wastes time used for un-needed pruning.

Have you ever seen the inside of shrubs that have been excessively pruned for years?

I warn you, it isn’t pretty…

sustainable landscape

Not too pretty, is it?

Over time, flowering shrubs that have been excessively sheared, can develop large dead areas and eventually decline.  This leads to old shrubs being removed and a new ones put in.

MISTAKE #4

Growing plants that aren’t adapted to your climate.

sustainable landscape

Plants that are not well-adapted to your local climate require excessive resources such as extra water, fertilizer and other maintenance.

Queen palms (Syagrus romanzoffianum) are just one example of a plant that often struggles in our southwestern, desert climate.  No matter what we do, they will never look as nice as the queen palms growing in more tropical climates.

The lesson to be learned from this is that not planning for the mature plant size, over-planting, over-pruning and wrong plant selection uses up a lot of resources.

1. Excessive amounts of water are used due to over-planting, over-pruning and for plants not well-adapted to our arid climate.

2. Money is wasted on buying more plants then are needed.

3. The costs of maintenance used for excessive planting and pruning include another resource – gasoline.

4. Declining health of plants that have not been pruned properly or those ill-suited for our dry, hot climate.

************************

So how does your landscape compare with examples, above?

If you see some similarities – don’t worry.  There are things that you can do to decrease the amount of resources that go into maintaining your landscape.

My goal is to help you toward not only a more sustainable landscape, but one that is also beautiful and attractive.

In my next post, we will start to talk about

“Small Steps Toward a Sustainable Landscape”.
