Spot-treat broadleaf weeds with a 2,4-D herbicide

What to Do

Once broadleaf weeds like dandelions, clover, and plantain are actively growing in spring, spot-spray them with a 2,4-D based post-emergent herbicide. Apply when daytime temps are between 60-85°F and no rain is expected for 24 hours.

Why It Works

2,4-D is a selective herbicide that kills broadleaf weeds without harming grass. It is absorbed through the leaves and disrupts the weed's growth hormones, causing it to twist, wilt, and die within 1-2 weeks. It is the most widely used lawn herbicide worldwide.

Tips

• Spot-spraying is more targeted and uses less chemical than broadcast applications.
• Products like Weed B Gon and Trimec combine 2,4-D with other active ingredients for broader weed control.
• Avoid spraying near vegetable gardens, ornamental plants, or when wind exceeds 5 mph.
