Raking Pine Straw Over Pre-Emergent: No Problem

Raking pine straw off a Bermuda lawn after pre-emergent application won't significantly reduce the herbicide's effectiveness. Research shows even core aeration—which disturbs soil far more aggressively—has minimal impact on pre-emergent activity.

Practical Implication

You can maintain a clean lawn appearance without compromising weed prevention. The pre-emergent barrier remains intact at the soil surface where it stops weed seed germination.
