Choosing the Right Herbicide to Tackle Crepe Myrtle Problems
Crepe myrtles are beautiful flowering trees, but sometimes they can become unwanted guests. Whether it’s a sprout from a stump or a sapling that’s taken root where you don’t want it, you might need to get rid of it. This guide will help you find the best herbicide to get the job done effectively and safely.
Why Use an Herbicide for Crepe Myrtle?
Herbicides are chemical solutions designed to kill unwanted plants. For crepe myrtles, they offer a targeted way to remove them, especially when digging them out is difficult or impossible. This is often the case for resprouts from cut stumps.
Key Features to Look For in a Crepe Myrtle Herbicide
1. Active Ingredient: The Powerhouse
The active ingredient is what actually kills the plant. For tough woody plants like crepe myrtles, you’ll want herbicides with strong active ingredients.
- Glyphosate: This is a very common and effective herbicide. It’s a “non-selective” herbicide, meaning it kills most plants it touches. It works by being absorbed through the leaves and moving down to the roots.
- Triclopyr: This is another excellent choice for woody plants and brush. It’s also non-selective but is particularly good at targeting trees and shrubs.
- 2,4-D: This is often found in combination with other herbicides and is effective against broadleaf weeds and woody plants.
2. Formulation: How it’s Packaged
Herbicides come in different forms. The best form often depends on how you plan to use it.
- Concentrate: You mix this with water. It’s usually more cost-effective for larger jobs.
- Ready-to-Use (RTU): These are pre-mixed and come in a spray bottle. They are convenient for small areas or spot treatments.
3. Application Method: Getting it Where it Needs to Go
Think about how you will apply the herbicide. Most crepe myrtle herbicides are applied as a foliar spray (on the leaves) or as a cut-stump treatment.
- Sprays: Many herbicides come in spray bottles or can be used with a garden sprayer.
- Drench/Brush-on: Some concentrates are designed to be brushed or poured directly onto the cut surface of a stump.
Important Materials for Application
Beyond the herbicide itself, you’ll need a few other things:
- Gloves: Always wear chemical-resistant gloves to protect your skin.
- Eye Protection: Safety glasses or goggles are a must.
- Long Sleeves and Pants: Cover up to avoid skin contact.
- Measuring Cups/Spoons: If using a concentrate, you need to measure accurately.
- Sprayer or Brush: Depending on the herbicide and application method.
- Water: For diluting concentrates.
Factors That Improve or Reduce Quality
What Makes a Herbicide Work Better?
- Correct Application: Applying the herbicide to actively growing leaves or a freshly cut stump is crucial.
- Weather: Applying on a calm, dry day with no rain expected for at least 24 hours helps the herbicide stick and be absorbed.
- Plant Health: Healthier plants absorb herbicides better.
What Can Make it Less Effective?
- Rain: Rain can wash the herbicide off before it’s absorbed.
- Wind: Wind can blow the spray onto desirable plants.
- Incorrect Dilution: Too little can make it ineffective; too much can be wasteful or harmful.
- Old Product: Expired herbicides may lose their potency.
User Experience and Use Cases
Most people use herbicides for crepe myrtle problems in a few common situations:
- Removing Sprouts from Stumps: After cutting down a crepe myrtle, you’ll often see new shoots growing from the stump. Treating these with a herbicide is much easier than constantly mowing them.
- Clearing Overgrown Areas: If a crepe myrtle has gotten too big or is growing where it shouldn’t, an herbicide can help clear it out.
- Preventing Regrowth: For persistent problems, an herbicide can ensure the crepe myrtle doesn’t come back.
Frequently Asked Questions (FAQ)
Q: Is it safe to use herbicides around pets and children?
A: Always read and follow the label instructions carefully. Keep pets and children away from the treated area until it is completely dry. Some herbicides are safer than others, but caution is always advised.
Q: How long does it take for the herbicide to kill the crepe myrtle?
A: It can take several days to a few weeks for the plant to show signs of dying. This depends on the herbicide, the plant’s size, and the application method.
Q: Can I use a general weed killer, or do I need something specific for crepe myrtles?
A: While some general weed killers might work on young crepe myrtles, mature trees or stumps often require a stronger, woody plant-specific herbicide like those containing glyphosate or triclopyr for best results.
Q: What is the best time of year to apply herbicide to a crepe myrtle?
A: The best time is when the plant is actively growing, usually in the spring or early summer. For cut stumps, apply immediately after cutting.
Q: Will the herbicide kill my grass if I spray it nearby?
A: Glyphosate and triclopyr are non-selective, meaning they will kill grass and other plants they touch. Be very careful to only spray the crepe myrtle or the cut stump.
Q: How do I apply herbicide to a cut crepe myrtle stump?
A: Immediately after cutting the tree, apply a concentrated herbicide directly to the fresh cut surface using a brush or a small applicator. This prevents the tree from resprouting.
Q: Can I use a systemic herbicide?
A: Yes, systemic herbicides like glyphosate are ideal because they are absorbed by the plant and move to the roots, killing the entire plant.
Q: What if the crepe myrtle is very large?
A: For very large trees, you might need to make several cuts into the bark and paint the herbicide onto those cuts, or use a more concentrated application on the stump.
Q: Are there any natural or organic ways to kill crepe myrtles?
A: While some natural methods exist, they are often less effective and slower for woody plants like crepe myrtles. Repeatedly cutting sprouts can eventually weaken the plant, but herbicides are generally more reliable for complete eradication.
Q: Where can I buy herbicides for crepe myrtle?
A: You can find herbicides at garden centers, hardware stores, and online retailers. Always check the product label to ensure it’s suitable for woody plants.
