Your Guide to Choosing the Best Broadleaf Herbicide for Lawns
A beautiful, green lawn free from pesky weeds like dandelions and clover is the dream for many homeowners. Broadleaf herbicides are the tools you need to achieve this. But with so many options available, how do you pick the right one? This guide breaks down what matters most when buying a broadleaf herbicide for your lawn.
Key Features to Look For
When shopping, focus on these important features. They tell you how well the product will work for your specific needs.
1. Selective Action
- What it means: A good broadleaf herbicide targets broadleaf weeds (weeds with wide leaves) but leaves your grass unharmed.
- Why it matters: You want to kill the weeds, not your desirable turfgrass like fescue or bluegrass. Look for labels that specifically mention safety for your lawn type.
2. Weed Spectrum Coverage
- What it means: This lists all the weeds the product is designed to kill.
- Why it matters: Check the label! If you have stubborn ground ivy or plantain, make sure those weeds are listed as controllable.
3. Application Type (Liquid vs. Granular)
- Liquid: Mixes with water and sprays on. It often works faster.
- Granular: Looks like fertilizer pellets. You spread it with a spreader. It often lasts longer in the soil.
4. Speed of Results
- Some products work quickly, showing results in just a few days. Others take longer but might offer longer residual control (preventing new weeds).
Important Materials: Understanding the Ingredients
The ingredients are the engine of the herbicide. Most effective broadleaf killers use a combination of chemicals to attack the weeds from different angles. You will often see names like 2,4-D, Dicamba, or MCPP/MCPA.
- Active Ingredients: These are the chemicals that actually do the killing. Check the ratio of these ingredients. More potent formulas usually have higher concentrations or a combination of three active ingredients for broad-spectrum control.
- Inert Ingredients: These help the active ingredients stick to the weed leaves or mix properly in the water. They don’t kill the weeds, but they help the active ingredients do their job better.
Factors That Improve or Reduce Quality
The quality of an herbicide depends on how effectively it performs under real-world conditions.
Factors That Improve Quality:
- Rainfastness: How quickly the product dries and sticks to the weed so that rain won’t wash it away immediately. Look for products rated as “rainfast within one hour.”
- Temperature Range: High-quality products work well across a wider temperature range, giving you more flexibility when applying.
- Concentration: Higher concentrations generally mean you get more killing power per bottle, making it more economical.
Factors That Reduce Quality:
- Improper Mixing: If you use too little water with a concentrate, the product might be too strong and could potentially burn the grass.
- Old or Stored Product: Herbicides can lose effectiveness if stored incorrectly (like in freezing temperatures or extreme heat). Always check the expiration date.
User Experience and Use Cases
Think about how you plan to use the product. Your experience will change based on your tools and your lawn’s current condition.
- Spot Treating vs. Broadcast Application: If you only have a few weeds, a ready-to-use spray bottle (spot treating) is easier. If your lawn is covered, a concentrate you mix and apply with a large sprayer (broadcast) is more efficient.
- Lawn Maturity: Newer lawns or grass seedlings are very sensitive. Always choose the mildest, safest formula for young turf.
- Ease of Use: Granular products are often simpler for beginners because they don’t require mixing. Liquid concentrates require careful measuring.
10 Frequently Asked Questions (FAQ) About Broadleaf Herbicides
Q: When is the best time of year to apply broadleaf herbicide?
A: Fall is often the best time. Weeds are actively pulling nutrients down to their roots, which helps the herbicide travel deeper and kill the entire plant, including the root.
Q: Can I use broadleaf herbicide when it’s hot outside?
A: Generally, no. Most labels advise against application when temperatures are above 85°F (about 30°C). High heat increases the risk of damaging your desirable grass.
Q: How long should I wait before mowing after applying?
A: You should wait at least two days after application before mowing. This gives the herbicide time to be absorbed by the weed leaves.
Q: Is it safe to let my dog walk on the lawn after treatment?
A: Wait until the treated area is completely dry. This usually takes a few hours. Always check the specific product label for the required re-entry interval.
Q: Will this kill clover?
A: Yes, most quality broadleaf herbicides are specifically designed to control clover, which is a very common broadleaf weed.
Q: How long does it take to see results?
A: Results vary, but you often start seeing yellowing or curling of the weed leaves within 3 to 7 days.
Q: Can I use this product near my flower beds?
A: Be very careful. Drift (spray landing where it shouldn’t) can harm desirable flowers and shrubs. Use a shield or apply granular products very carefully when near sensitive plants.
Q: Do I need to water the lawn after applying granular herbicide?
A: Yes, usually. Watering activates the chemicals in granular products, helping them start working and moving them into the soil around the weed roots.
Q: What if it rains right after I spray?
A: If the product is not rainfast yet, the rain might wash the herbicide off the leaves. You may need to reapply based on the label instructions, but usually, wait at least 24 hours.
Q: Can I use this on a new lawn (sod or seeding)?
A: No. Wait until the grass has been mowed at least three times (usually 4 to 6 weeks old) before applying any weed killer to prevent killing the new grass.
