Choosing the Right Weed Killer for Your Bermuda Grass Lawn
Bermuda grass is a tough, beautiful lawn grass. But unwanted weeds can quickly ruin its look. Finding the right weed killer is key. This guide will help you choose the best product to keep your Bermuda grass green and weed-free.
Key Features to Look For
When shopping, focus on what the product can actually do.
- Selective Action: This is the most important feature. A selective weed killer targets only the weeds, leaving your desirable Bermuda grass unharmed. Look for labels that specifically mention safety for warm-season grasses like Bermuda.
- Weed Type Targeting: Does the product kill broadleaf weeds (like dandelions) or grassy weeds (like crabgrass)? Some products handle both. Check the label to ensure it lists the weeds you actually have.
- Pre-emergent vs. Post-emergent: Pre-emergents stop seeds from sprouting. Use these early in the season. Post-emergents kill weeds that are already growing. You often need both types for total control.
- Speed of Action: How fast do you want results? Some liquid sprays work within hours, while granular products might take a week or two.
Important Materials in Weed Killers
Weed killers contain active ingredients that do the killing. Knowing these helps you compare brands.
For post-emergent control, common active ingredients for Bermuda lawns include products containing 2,4-D, Dicamba, or MCPP. These chemicals attack the broadleaf weeds’ growth system.
For pre-emergent control, look for ingredients like Pendimethalin or Prodiamine. These create a barrier in the soil that stops new weed seeds from growing roots.
Always read the list of inert ingredients too. These help the chemical stick to the leaf or mix properly in water. High-quality surfactants (sticking agents) often improve how well the product works.
Factors That Improve or Reduce Quality
The quality of your weed killer depends on how well it’s made and how you use it.
Quality Boosters: Products with higher concentrations of the active ingredient often provide better results, meaning you use less product overall. Weed killers formulated to resist washing away quickly from rain or watering are also higher quality.
Quality Reducers: Poorly mixed or old products can be ineffective. If a liquid product has separated in the bottle, it might not work correctly. Furthermore, using a product meant for cool-season grasses (like Fescue) on Bermuda grass will almost certainly damage or kill your lawn.
User Experience and Use Cases
How easy the product is to use greatly affects your success.
Ease of Use: Ready-to-use spray bottles are great for small jobs or quick touch-ups. Concentrate formulas are more economical for large lawns but require careful mixing with a sprayer tank.
Use Cases: If you have a major crabgrass invasion, you need a strong pre-emergent applied before the weather gets hot. If you see a few dandelions popping up in July, a quick spot treatment with a selective liquid spray is the best choice. Always follow the label instructions regarding temperature and watering before and after application. Applying herbicides when temperatures are too high can stress the Bermuda grass and increase the risk of damage.
10 Frequently Asked Questions (FAQ) About Bermuda Grass Weed Killers
Q: Can I use standard weed killer on my Bermuda grass?
A: No, not all of them. You must use a selective weed killer that is specifically labeled as safe for use on Bermuda grass. Other products can turn your lawn yellow or kill it.
Q: When is the best time to apply pre-emergent weed killer?
A: Apply pre-emergents in early spring, usually when soil temperatures reach 55 degrees Fahrenheit for several days in a row. This stops seeds like crabgrass before they sprout.
Q: How long after spraying must I wait to water my lawn?
A: This varies by product. Most require the spray to dry completely, usually 2 to 4 hours, before rain or watering. Check the product label carefully.
Q: Will this kill clover growing in my Bermuda lawn?
A: If the product lists clover (a broadleaf weed) as a target, yes. Ensure your product is a broadleaf killer.
Q: Can I apply fertilizer and weed killer at the same time?
A: It is usually best to separate these applications by a week or two. Some combination products exist, but applying them separately often yields better results for both.
Q: What should I do if the weeds look worse after applying the killer?
A: Post-emergent killers often cause weeds to curl, yellow, or wilt within a few days. This means the product is working. If the Bermuda grass turns yellow, you may have applied too much or the temperature was too high.
Q: Are granular or liquid weed killers better for Bermuda grass?
A: Liquids often provide faster contact killing. Granules work well when spread evenly and watered in, offering longer residual control. Neither is universally better; it depends on your preference and watering schedule.
Q: Do I need to wear special gear?
A: Yes. Always wear long pants, closed-toe shoes, and gloves. If you are spraying a concentrate, eye protection is also highly recommended.
Q: How often should I reapply post-emergent killer?
A: Reapply only when you see new weeds growing, following the minimum reapplication interval listed on the label (usually every 2–4 weeks).
Q: Can I use a weed killer if my Bermuda grass is stressed or dormant?
A: Avoid applying most herbicides when the grass is actively growing but stressed by drought or extreme heat. Wait until the grass is healthy or fully dormant (brown) for the safest results.
