The Pitfalls of Improper Pruning: A Tale of Flowering Shrubs

Flowering Shrubs need pruning, but how they are pruned makes such a difference. Aren’t these shrubs beautiful?

You would think that the beauty of these shrubs, in flower, would be enough for people to stop pruning them into absurd shapes, but sadly, this is not the case. In the Desert Southwest, there is an epidemic of truly horrible pruning that affects not only Texas Sage (Leucophyllum species), but also Cassia (Senna species), Fairy Duster (Calliandra species), and even Oleander.

The Consequences of Excessive Pruning

Unsurprisingly, excessive pruning like this is NOT healthy for shrubs and it strips them of their beauty.

The ‘Frisbee’ Phenomenon

You don’t have to go far to see these sad shrubs. All you need to do is drive down the street as I did…

flowering shrubs need pruning

Okay, it should be rather obvious, but I will say it just the same,  “Do not prune your shrubs into the shape of a ‘frisbee’.

The ‘Pillbox’ Pruning

I kept driving and found even more examples of truly awful pruning.  Sadly, all are within a 5-minute drive of my house.

I call this ‘pillbox’ pruning. These Texas Sage & Cassia shrubs were located across the street from the ‘frisbee’ shrubs.

Leucophyllum frutescens 'Green Cloud

An attempt at creating a ‘sculpture’? Texas Sage ‘Green Cloud’ (Leucophyllum frutescens ‘Green Cloud’)

 A second attempt at creating a sculpture?

Let’s get real. Shrubs pruned this way does nothing to add beauty to the landscape. And, when pruned this way, they cost more, take more time, and use more water – it’s true!

‘Cupcake’ Pruning: An Unappetizing Approach

Now on to some of my favorite ‘cupcake’ examples:

Leucophyllum frutescens 'White Cloud

An entire line of ‘cupcakes’. ‘White Cloud’ Texas Sage (Leucophyllum frutescens ‘White Cloud’) 

flowering shrubs need pruning

Do you think they use a ‘level’ to make the tops perfectly flat? I honestly wouldn’t put it past them.

flowering shrubs need pruning

You can see the dead area on the top, which is caused from this shrub being sheared repeatedly.

flowering shrubs need pruning

This dead growth is caused by lack of sunlight.  Repeated shearing (hedge-trimming) keeps sunlight from reaching the interior of the shrub.   As a result, branches begin to die.

After driving around for a while, I drove toward home when I saw the saddest ones of all…

Flowering Shrubs Need Pruning, but these are Disappointing

 Now if you look closely, you can see a light layer of gray-green leaves, which really don’t begin to cover the ugly, dense branching that has been caused by years of repeated shearing.

Texas Sage

 I actually like topiary, but not when done to a Texas Sage. Some people prune up their shrubs so that they can clean up the leaves underneath more easily.

The Goal Should be to Prune with Purpose

Now, I am not against formal pruning, when performed on the right plants. But, it is not attractive when done on flowering, desert plants and it is also unhealthy for the shrubs themselves and contributes to their early death in many cases.  Add to that the fact that it greatly increases your maintenance costs due to repeated pruning and having to replace them more frequently.

Now if you have shrubs that look like any of these pruning disasters, don’t panic! They can be fixed in most cases.

 Now, why would anyone want to remove the flower buds from your shrubs by shearing,  when you can have flowers like this?

Join the ‘Cupcake-Free’ Movement

If you are tired of unnaturally shaped shrubs in your landscape, I understand. Believe it or not, most flowering shrubs need pruning once or twice a year at most – and NOT the type of pruning into weird shapes. I find it ironic that your yard will look better when you do less.

So, if you are wanting to declare your landscape a ‘cupcake-free’ zone, I have something I think you’re gonna love. I invite you to check out my popular online shrub pruning workshop where I teach you how to maintain flowering shrubs by pruning twice a year or less. Hundreds of students have taken the course and are reaping the rewards of a beautiful outdoor space filled with colorful shrubs at a fraction of the work.

Are you ready to break out of the cycle of green blobs?

Addressing Issues in Landscaping: A Guide to Pruned Shrubs

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. In this article, we’ll examine a landscape example and highlight the problems it presents.


Introduction: Identifying Landscape Problems

A while 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 essential to clarify that the purpose of showcasing landscapes like this isn’t to shame homeowners. Instead, our goal is to help you identify common problems and provide straightforward solutions to correct or prevent them in your landscaping projects.

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. Overcrowded Shrubs

It’s obvious that there are too many plants in this area and the mature size of the shrubs weren’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. They are clearly spaced too closely together due to poor pruning.

2. Lack of Plant Diversity

As you can see, there is a tree, a couple of succulents (prickly pear cactus & yucca), and a LOT of shrubs. While there is a variety of plants in the landscape, there’s an overabundance of shrubs compared to other types. The landscape lacks a balanced mix of different plant types, resulting in an imbalance that affects its overall aesthetics.

3. Incorrectly Pruned Flowering Shrubs

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

landscape-no-no-badly-pruned-shrubs

Solutions: Correcting the Landscape

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

  • Remove excess shrubs. Remove 24 of the 32 shrubs. You will be then have 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. Place shrubs up near the house. This anchors the corners of the landscape, and flank an entry.
  • Severely prune back remaining shrubs. Many shrubs 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. Do this pruning in spring. The key is to keep hedge trimmers away from your newly pruned shrubs forever. Prune with 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.

Achieving a Balanced and Beautiful Landscape

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

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

Beware the Pretty Face: The Illusion of Clematis Flowers

Clematis flowers are so pretty. Do you ever find yourself transfixed by a pretty face flower? I have. In fact, I’ve rarely seen a flower that I didn’t like. However, sometimes a pretty face, or in this case, a flower, can easily fool us.

Deceptive Beauty: The Story of Clematis Flower Vines at the Grocery Store

clematis flower at the grocery store

Over the weekend, I made a quick trip to my local grocery store where I noticed a display of beautiful flowering plants that stopped me dead in my tracks. 

Right by the entry was a collection of lovely clematis vines. Their lush green foliage and large purple flowers were gorgeous and enticed passersby into taking one home.

This made me mad, and I don’t get angry quickly. So, why am I upset? It’s not because I have anything against clematis – I think that they are lovely and have taken some photos of them throughout my garden travels including these below.

The Misfit Clematis: Unsuitable for Phoenix and Low Desert Areas

If you have paid attention to where I took the pictures of clematis, you may begin to understand why seeing this outside my Phoenix area grocery store upset me. The reason is that clematis don’t thrive in a low desert climate. They need extensive irrigation and attention.

The Reality of a Clematis Flower: A Lesson in Garden Impulse Buying

The problem is, the average person doesn’t know this and envision how nice the clematis will look in their garden, so they hand over $25 and carry their new plant home with the assumption that the store wouldn’t sell plants that very difficult to grow in their area. 

Sadly, they are wrong. Unless they possess extensive gardening experience and knowledge about clematis, they will end up with a vine that barely clings to life within a few weeks and will blame themselves for its condition.

Sequim, Washington (clematis flower)

Sequim, Washington

The moral of this story? Don’t be fooled by a pretty face clematis flower. Avoid impulse buys and research before buying plants for your garden. If you see a plant that you have never seen before, there is a greater chance that it may have difficulty growing in your climate. Choose a desert adapted vine instead.

The ‘Torch Glow’ Bougainvillea Dilemma

In my last post, I showed you a photo of a “landscape no-no” and challenged you to guess what the problem was.

Were you able to guess what is wrong with this planting?

I gave a hint that the plant in the middle is ‘Torch Glow’ Bougainvillea.

Well, I am happy to report that most of you were right about the problem.

Torch Glow Bougainvillea as a small shrub in a narrow location

Size Matters: ‘Torch Glow’ Bougainvillea

You see, ‘Torch Glow’ Bougainvillea (or any bougainvillea) for that matter, is too large to be planted in such a small area.

Although this bougainvillea shrub is small now, it will soon grow very big…

Torch Glow Bougainvillea as a young plant

I planted the ‘Torch Glow’ Bougainvillea, above, in my father-in-law’s back garden. At the time I took this photo – it was less then 2 years old.

Personally, I like this variety of Bougainvillea – it has an unusual shape compared to other types of Bougainvillea and produces less litter. It does grow very fast and will soon outgrow a small area.  At maturity, it can reach heights of 8 feet and 4 feet wide.

So, back to the original planting in the first photo.  The problem that will soon occur is that the ‘Torch Glow’ Bougainvillea will grow wider and overhang the pathway to the entry.

Of course, at first, the homeowner will attempt to keep the Bougainvillea pruned back – but he would be fighting a losing battle.  This shrub grows too big.

Did I also mention that this particular plant has THORNS?

You never want to put any type of plant or tree that has thorns, next to an area where people walk.  No one likes to get stuck by a thorn.

bush Rosemary

The Rosemary Predicament

This homeowner also had another landscape problem directly across the pathway from the bougainvillea…

He has a bush Rosemary planted in a tiny area that was 3 inches wide.

As you can see, he was already busy pruning it to keep it from hanging over the pathway.

Soon, the base of the plant will become more woody with less leaves as it grows, which will make it very unattractive.

In addition, the small amount of soil, will affect the ultimate health of the rosemary as well. It might become difficult to irrigate with a tiny root space as well.

The Lesson Learned: Research and Plan

**So what is the lesson learned from this “landscape no-no”?

Take a few minutes to research the plants you select before you plant them (don’t always rely on your landscaper’s advice – check for yourself).  Make sure the plants will fit that particular area once they reach their mature size.

I hope this will help you to avoid a similar mistake in the future in your garden.

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

I am still patiently (not really) waiting to plant my fall vegetable garden.  We are buying compost and manure this weekend to replenish the existing soil in the gardens and I hope to have everything planted soon.

I promise to keep you updated 🙂

landscape consultation

Do you ever wonder if you are doing things right in your landscape?

If a plant or tree doesn’t look too well, do you wonder if it is something you are doing wrong?

When I am called to do a landscape consultation, my client usually has a primary concern.  But, part of my job is to also look at the landscape as a whole and point out other problems – hopefully before they affect the plant negatively.

So, I decided to start posting photos of problems I have spotted during consults in hopes that I can help you too.

Below, are two pictures of a very common landscape mistake that I see constantly.  Usually the homeowner/client has no idea that they are doing anything wrong.

Can you tell what is wrong?

It isn’t always super obvious…

This is what (Hesperaloe parviflora)looks like when its flowering.

Every time I see a Red Yucca (Hesperaloe parviflora) in full bloom, I remember a disastrous pruning incident that still makes me laugh and groan at the same time….

Red Yucca Plant Pruning Disaster

I was working as a horticulturist at a golf course and I was fortunate to have a wonderful crew of landscapers.  One of the landscaper’s was Abel.   He was in charge of maintaining the clubhouse landscape grounds.  One day, he came in to my office with a huge smile on his face and told me that in addition to the work that I had already assigned him, he had pruned some plants around the clubhouse and couldn’t wait to show me what a great job he did.

I went with him to see what he had done and when we got there, I just couldn’t believe it….. he had pruned off all the tops of the 30 Red Yucca (Hesperaloe parviflora) plants!!!  I was in complete shock and standing beside me was a smiling Abel, whose was so proud of his work and who honestly did not have a clue that he had done something wrong.  

This is what Red Yucca looks like when it has not been pruned correctly

This is what was left of one of the (Hesperaloe parviflora) plants.

Well, I didn’t have the heart to tell him that you never should prune the tops of Red Yucca leaves.  But, I did tell him that he needed to check with me before he pruned anything else around the clubhouse.

Beautiful stand of red yucca

This story has a happy ending…..the Red Yucca eventually grew back and Abel continued to work for me about a year with no further pruning disasters.  He then left to go back to Mexico where he became mayor of his small town.

How to Prune a Red Yucca (Hesperaloe parviflora) Plant

Season for Red Yucca Pruning:

Prune the Red Yucca plant after the flowers have faded, typically in late summer or early fall.

Flowering Stalks:

Trim back the flowering stalks to the base of the plant using clean and sharp pruning shears. This helps maintain a tidy appearance and encourages new growth.

Simple Approach to Yucca Pruning:

Pruning Red Yucca is straightforward. Just focus on removing the faded flowering stalks and any dead or damaged leaves.

Avoid Cutting the Top:

Red Yucca plants along a walking path

Be cautious not to prune the top of the plant, as this can make it look unattractive and slow down its growth recovery. The crown of the plant should be left intact.

Red Yucca Minimal Maintenance:

Red Yucca is known for being a low-maintenance plant, and its pruning requirements are minimal. This makes it an ideal choice for a southwestern garden.

Pruning Tools:

Use clean and sharp pruning shears to make precise cuts, which promote quicker healing and reduce the risk of disease transmission.

Protective Gear in the Desert Garden:

Wear gloves and protective eyewear while pruning to shield yourself from the plant’s sharp leaves and any debris.

Sanitize Your Tools:

Before and after pruning, disinfect your pruning tools to prevent the spread of any potential diseases between plants.

Observe and Improve Structure and Plant Shape:

Take a moment to observe the plant’s overall structure and health before pruning. Remove only what is necessary for the plant’s well-being and aesthetics.

Careful Pruning:

If you’re unsure about pruning, start conservatively by trimming a little at a time. You can always prune more if needed, but you can’t undo an overly aggressive trim

Remember, Red Yucca is quite resilient, and with proper pruning, you can enhance its appearance and ensure its continued health in your southwestern garden.

So, have you seen any pruning disasters lately?  I seem to be seeing quite a few….

Enjoying the Sun…..No Sunscreen Required

Sometimes when I am driving around, I see a poorly pruned tree or shrub, and I just cringe.  It never ceases to amaze me the crazy ways that people take care of their plants.  Whenever I see plants like this, I whip out my camera and quickly take a photo and then drive away before the homeowner asks what I am doing.

I mean if they catch me taking a photo, I can’t very well tell them, “I am taking pictures of the horrible way you prune your trees ?” Can I?  Well, I probably could and should, but I am too chicken to confront people that way.  I have no problem confronting people about their horrible pruning if they have asked me over to do a consult on their landscaping.  I just like an invitation first before I tell people what they are doing wrong 😉

Although, the primary purpose of this post is to entertain with photos of truly awful pruning disasters.  I just have to step up on my “high horse” for just a minute regarding one type of pruning that is widespread.  So please bear with me…

One of the most harmful types of pruning in regards to trees is called ‘topping’ the tree.  It removes a lot of the top growth.  This is usually done to shorten the tree and to preserve a view.  The topping is NOT good for the tree and accelerates more top growth.  The new branches are weakly attached and are much more liable to break, which can cause damage to what is underneath.  Also, topping trees greatly stress the tree which can make them susceptible to insect and certain environmental factors.  You can read more about topping trees here Tree Care.

A few years ago we suffered a severe micro-burst during the summertime at the community where I was working.   The tree above snapped off in the high winds at a weak point in the trunk, which was weak due to improper pruning that was done a long time before the storm.

Orange tree

 This is an Orange tree that has been pruned correctly.

The Citrus tree, above, has been pruned the right way, but I just had to include it in this post because it is so humorous.  Look closely (you can click on the photo to enlarge)…. the homeowner tied CDs to the tree to scare off the birds from eating the fruit.

Many people prune their Citrus trees up so that they look more like a ‘typical’ tree.  But what many people don’t know is that the lower branches produce the most fruit, the sweetest fruit and protects the trunk from sunburn.

Now for some truly awful examples of shrubs….remember the “cupcakes” from a previous post?

Cordia

 Little Leaf Cordia pruned into a ‘ball.’

In an earlier post, we covered the epidemic of pruning shrubs into the shapes of ‘cupcakes.’  Well, there is another epidemic in where people prune their shrubs into the shape of a ‘ball.’  We call this type of pruning, “Poodle-Pruning” because the shrubs resemble the ball shapes that poodles have when groomed.  Either way, ‘cupcakes’ or ‘poodle,’ neither are good for your shrubs and take away from their beauty.

Feathery Cassia shrubs

 Feathery Cassia shrubs with large areas of dead growth.

One of the results of repeated shearing of your shrubs into specific shapes (cupcakes or balls), results in areas of dead growth.  This is because sunlight cannot penetrate inside the shrub and it is constantly trying to replace the growth that is cut off constantly.  There is a cure, which I will cover in a spring time post, which is when corrective pruning should be done.

Thunder Cloud Sage

 Thunder Cloud Sage, unpruned

Now I don’t recommend going to the other extreme, above, and not pruning.  Just do it correctly.  So, if you have any ‘cupcakes’ or ‘poodles’ in your landscape, do not panic!  I will cover the correct ways to prune many shrubs in the spring, which is the time that it should be done.

So, take care to prune properly, because you never know when I will come driving by with my camera….

Has this happened to you?  You walk through the nursery, and you spot “the perfect plant.”   You can envision it in your yard and know precisely where you will put it.  

After coming home and planting it, you pat yourself on the back for finding such a great plant.  Time passes, and your beautiful plant starts to grow, and grow and grow.

Fast forward a year or two now it looks bad unless you constantly prune making it high maintenance.  Now your beautiful plant no longer looks so lovely (above and below).  It now looks more like a ‘cupcake’ because you have had to prune it back to keep it small enough for your space.  

No more flowers, no nice foliage…

perfect plant

 More ‘cupcakes.’

Unfortunately, there is an epidemic in our area of homeowners and landscapers who prune flowering shrubs so that they end up looking like ‘cupcakes’ or ‘poodles’ just so that they fit into their allotted space.  More about that in another post…

 Texas Sage ‘Green Cloud’ in its natural shape. They can grow up to 8 ft. high and wide but can be easily maintained at a more moderate 4′ x 4′.

Texas Sage Flower

Also with flowers this beautiful, why plant it somewhere where you will have to prune them off so that it can fit?  

So our lesson is…. be sure to READ THE LABEL of plants before you buy them, which should list how large they will grow, along with the correct sun exposure.  If it’s not listed, ask the nursery salesperson for this information, or use your smartphone to get the information.  

Then you can go home and place your new “perfect plant” where they will have plenty of room to ‘stretch out’ and dazzle you with their beauty. 

**Allowing enough room for plants is just part of what it takes to grow attractive shrubs.  Pruning is the next part of the equation.  Click here for guidelines on how to properly prune your flowering shrubs.

Ficus nitida

Ficus Nitida simply the wrong plant, and usually in the wrong place.

I think this photo probably speaks for itself…..

But, I will add to it by saying that it is vital to realize that the little, spindly tree that you plant WILL GROW. Be sure to check the mature size of any tree, (or any plant for that matter), before you plant so you can be sure that there is ample room for growth.

By the way, the tree above is a Ficus nitida, which is a beautiful, dark green tree. But, it does grow enormous, as does its roots, making it unsuitable from most residential landscapes.
