Herbicide Drift Killed Part of Your Hedge: Assessment and Recovery Steps

Likely Scenario

Neighbor sprayed weed killer under 30–40 yr hedge. Hedge parts brown, branches snap dry. Probably a contact herbicide (not soil-active). Damage is done; won't spread further.

Steps

1. Ask neighbor for herbicide name; check mode of action (Google).
2. Prune dead branches.
3. Water deeply to dilute any residual chemical.
4. If roots intact, hedge should resprout from base.
