Pre-Emergent – Diminishing Activity?
Q: I put pre-emergent on my common Bermuda lawn a couple of weeks ago. My pine trees drop a ton of pine straw. Would raking interfere with the action of the pre-emergent? Jen Marion, email
A: I don’t think you’d have a problem raking up the pine straw. Several studies have shown that even aerating a lawn does little to diminish pre-emergent activity.
