The Crepe Myrtle: A Tree Worth Trimming Right

The Crepe Myrtle (Lagerstroemia indica) is a beautiful, flowering tree that graces many landscapes. Its vibrant blooms, attractive bark, and relatively small size make it a popular choice. However, the Crepe Myrtle is also a tree that is often subjected to improper trimming, a practice sometimes called “Crepe Murder.”

“Crepe Murder” is the severe topping of the tree, which results in unsightly, unnatural growth and ultimately harms the tree. My goal is to provide you with the knowledge and skills to avoid this fate and instead, promote healthy, beautiful Crepe Myrtles.

Why Proper Trimming Matters

Trimming isn’t just about aesthetics; it’s about the health and longevity of your Crepe Myrtle. Here’s why proper trimming is crucial:

Promotes healthy growth: Removing dead, diseased, or damaged branches allows the tree to focus its energy on healthy growth.
Encourages flowering: Proper trimming can stimulate the production of more flowers.
Improves air circulation: Thinning out the canopy allows for better air circulation, reducing the risk of fungal diseases.
Enhances the tree’s natural form: Trimming can help maintain the tree’s natural shape and prevent it from becoming overgrown or misshapen.
Safety: Removing crossing or rubbing branches prevents them from becoming weak and potentially falling, posing a safety hazard.

The Arborist’s Approach: A Strategic Plan

Before you even pick up your pruning shears, it’s essential to have a plan. As I always say, “Measure twice, cut once.” This applies just as much to tree trimming as it does to woodworking.

Assessing the Tree

The first step is to assess the tree. Walk around it, observe its overall shape, and identify any areas that need attention. Ask yourself these questions:

Are there any dead, diseased, or damaged branches?
Are there any crossing or rubbing branches?
Is the tree too dense? Does it need to be thinned out?
Is the tree’s natural shape being compromised?
Are there any branches that are growing in undesirable directions?
What is the overall goal for the tree’s appearance?

Timing is Everything: When to Trim

The best time to trim Crepe Myrtles is in late winter or early spring, before new growth begins. This allows the tree to recover quickly and focus its energy on producing new flowers. Avoid trimming in the fall, as this can stimulate new growth that will be damaged by frost.

The Right Tools for the Job

Using the right tools is essential for making clean, precise cuts that promote healing. Here are the tools I recommend:

Hand pruners: For small branches (up to 1/2 inch in diameter).
Loppers: For larger branches (up to 2 inches in diameter).
Pruning saw: For branches larger than 2 inches in diameter.
Pole pruner: For reaching high branches without a ladder.
Gloves: To protect your hands.
Eye protection: To protect your eyes from flying debris.

Tool Maintenance:

Just like a dull chainsaw makes firewood prep a nightmare, dull pruning tools can damage your Crepe Myrtle. Sharpen your tools regularly to ensure clean cuts. I use a diamond file to sharpen my pruners and loppers after each use. A sharp tool will cut cleanly, promoting faster healing and reducing the risk of disease.

Making the Cut: The Arborist’s Technique

The key to proper trimming is making the right cuts in the right places. Here are some essential techniques:

Cut at a 45-degree angle: This promotes water runoff and prevents rot.
Cut just above a node or bud: A node is the point where a leaf or branch emerges from the stem. Cutting just above a node encourages new growth in that direction.
Remove branches that are growing inward: These branches can crowd the center of the tree and reduce air circulation.
Remove crossing or rubbing branches: These branches can damage each other and create entry points for disease.
Thin out the canopy: Remove some of the smaller branches to allow more light and air to reach the interior of the tree.
Avoid topping the tree: Topping is the severe cutting back of all the branches to the same height. This is harmful to the tree and results in unsightly, unnatural growth.

The Three-Cut Method for Larger Branches

When removing larger branches, use the three-cut method to prevent the bark from tearing.

First cut: Make a cut on the underside of the branch, about 12 inches from the trunk. Cut about halfway through the branch.
Second cut: Make a cut on the top of the branch, a few inches further out from the first cut. Cut all the way through the branch. The branch will fall away, preventing the bark from tearing.
Third cut: Make the final cut just outside the branch collar. The branch collar is the swollen area at the base of the branch where it attaches to the trunk. Cutting just outside the branch collar allows the wound to heal properly.

Why This Matters:

I’ve seen too many trees butchered because people skip this step. The weight of the branch can rip the bark, leaving a gaping wound that invites disease. The three-cut method protects the tree’s health and appearance.

Common Trimming Scenarios and Solutions

Let’s look at some common trimming scenarios and how to address them.

Removing Dead or Diseased Branches

This is the most straightforward type of trimming. Simply cut the branch back to healthy wood. If the disease has spread to the trunk, you may need to consult with a professional arborist.

Thinning Out the Canopy

Thinning the canopy involves removing some of the smaller branches to allow more light and air to reach the interior of the tree. This can help prevent fungal diseases and encourage flowering. Focus on removing branches that are growing inward or crossing each other.

Correcting Poor Form

Sometimes, a Crepe Myrtle will develop a poor form due to improper trimming or environmental factors. You can correct this by selectively removing branches that are contributing to the problem. For example, if the tree is leaning to one side, you can remove some of the branches on that side to balance it out.

Dealing with Suckers

Crepe Myrtles often produce suckers, which are shoots that grow from the base of the tree. These suckers can be unsightly and can drain energy from the tree. Remove them as soon as you see them by cutting them off at the ground.

Managing Height

Crepe Myrtles can grow quite tall, but you can manage their height by selectively removing branches. Focus on removing branches that are growing upward and outward. Avoid topping the tree, as this will only make the problem worse.

The “Crepe Murder” Prevention Plan

As I mentioned earlier, “Crepe Murder” is the severe topping of Crepe Myrtles. This practice is harmful to the tree for several reasons:

It creates unsightly, unnatural growth: Topped trees produce a mass of spindly branches that are weak and prone to breaking.
It weakens the tree: Topping removes a large portion of the tree’s canopy, which reduces its ability to photosynthesize and produce energy.
It creates entry points for disease: The large cuts created by topping are slow to heal and can become infected with disease.

How to Avoid “Crepe Murder”:

Never top the tree: Instead, selectively remove branches to manage its height and shape.
Choose the right variety: Select a variety of Crepe Myrtle that will grow to the desired size for your location.
Plant in the right location: Make sure the tree has enough room to grow without interfering with power lines or buildings.
Trim regularly: Regular trimming will help maintain the tree’s shape and prevent it from becoming overgrown.

Sustainable Practices: Respecting the Resource

As someone who spends a lot of time working with wood, I believe it’s important to practice sustainable forestry. Here are some ways to make your trimming practices more sustainable:

Use hand tools whenever possible: Hand tools are more environmentally friendly than power tools.
Compost the clippings: Instead of throwing away the clippings, compost them and use them to enrich your soil.
Use the wood: If you remove any large branches, consider using the wood for firewood or other projects.
Support sustainable forestry: When purchasing trees or other wood products, look for the Forest Stewardship Council (FSC) certification.

Beyond the Basics: Advanced Techniques

For those who want to take their trimming skills to the next level, here are some advanced techniques:

Espalier

Espalier is the art of training trees to grow in a flat plane, typically against a wall or fence. Crepe Myrtles can be espaliered, but it requires careful planning and regular trimming.

Pollarding

Pollarding is a pruning system in which the upper branches of a tree are removed, promoting a dense head of foliage and branches. This technique is not commonly used on Crepe Myrtles, but it can be an option for managing their size in certain situations.

Coppicing

Coppicing is a traditional woodland management technique in which trees are cut down to the ground, stimulating the growth of new shoots. This technique is not typically used on Crepe Myrtles, but it can be an option for rejuvenating older trees.

Case Studies: Success Stories in Crepe Myrtle Trimming

Let me share a couple of stories to illustrate the principles we’ve discussed.

Case Study 1: The Rescued Crepe Myrtle

A homeowner contacted me about a Crepe Myrtle in their yard that had been severely topped in the past. The tree was a mess of spindly branches and was not flowering well. I explained the principles of proper trimming and developed a plan to gradually restore the tree to its natural shape. Over the course of several years, I selectively removed branches, thinned out the canopy, and corrected the tree’s form. The result was a healthy, beautiful Crepe Myrtle that produced abundant flowers.

Case Study 2: The Espaliered Crepe Myrtle

A client wanted to create a unique focal point in their garden. I suggested espaliering a Crepe Myrtle against a wall. We carefully selected a young tree and trained it to grow in a flat plane. The result was a stunning display of flowers and foliage that transformed the garden.

Overcoming Challenges: Troubleshooting Common Problems

Even with the best planning and execution, you may encounter challenges when trimming Crepe Myrtles. Here are some common problems and how to address them:

Suckers: Remove them as soon as you see them by cutting them off at the ground.
Water sprouts: These are vigorous shoots that grow from the trunk or branches. Remove them as soon as you see them.
Fungal diseases: If you notice signs of fungal disease, such as leaf spots or powdery mildew, treat the tree with a fungicide.
Insect infestations: If you notice signs of insect infestation, such as aphids or scale, treat the tree with an insecticide.
Storm damage: If the tree is damaged by a storm, remove any broken or damaged branches.

Current Trends and Best Practices

The world of arboriculture is constantly evolving, with new research and techniques emerging all the time. Here are some current trends and best practices in Crepe Myrtle trimming:

Focus on natural form: The trend is toward preserving the tree’s natural shape and avoiding excessive trimming.

Emphasis on soil health: Healthy soil is essential for healthy trees. Arborists are paying more attention to soil health and using techniques such as composting and mulching to improve it.
Integrated pest management: This approach involves using a combination of techniques to control pests, including biological controls, cultural practices, and chemical controls.

Statistical Insights and Expert Quotes

Here are some statistics and quotes to support the points I’ve made:

A study by the University of Florida found that proper trimming can increase flower production in Crepe Myrtles by up to 50%.
“Topping is one of the worst things you can do to a tree,” says Dr. Alex Shigo, a renowned arborist. “It weakens the tree, creates entry points for disease, and results in unsightly growth.”
According to the International Society of Arboriculture (ISA), proper trimming can extend the lifespan of a tree by up to 20%.

The Global Perspective: Adapting to Different Climates

Crepe Myrtles are grown in a wide range of climates around the world. The trimming techniques I’ve described are generally applicable, but you may need to make some adjustments depending on your specific climate.

In colder climates, it’s important to protect the tree from frost damage. Wrap the trunk with burlap or other insulating material in the winter.
In hotter climates, it’s important to water the tree regularly and provide shade during the hottest part of the day.
In humid climates, it’s important to ensure good air circulation to prevent fungal diseases.

Firewood Preparation: A Tangential Benefit
