Repairing Lawn After Accidental Herbicide Application

Recovering from Weed-and-Grass Killer Damage

If a non-selective herbicide (like Roundup) was mistakenly applied to your lawn, yellow dead patches will appear. Recovery depends on the product's soil activity.

Steps to Repair

1. Check the label: Determine the herbicide's half-life. If it only works through foliage (not soil), you can reseed or plug immediately.
2. Water thoroughly: Flush the root zone to dilute any residual chemical.
3. Re-establish grass: For Bermuda, surrounding runners will fill in with water and fertilizer. For other grasses, reseed or plug dead areas and keep moist until established.

Important Note

If the product has soil activity (some Roundup formulations), wait until the label's recommended interval before reseeding to avoid killing new seedlings.

Time, water, and targeted re-planting will restore your lawn.
