Blue Spruce Tip Curl: 2,4-D Herbicide Drift, Not Root Uptake

Blue spruce tips turning pink after phenoxy herbicide (2,4-D) use underneath. Owner asks recovery odds after soil flushing.

Liquid 2,4-D: No Root Uptake

Does not move in soil, not absorbed by roots. Damage only from direct foliar contact.

Worst case: some needle curl/burn on sprayed tips. Tree recovers fully. Flushing soil unnecessary.

"Weed & feed" granules ARE root-absorbed and damage trees.

Spot treatment per label = safe.
