2,4-D Drift on Blue Spruce: Trees Usually Recover

Herbicide Drift Damage on Blue Spruce: Wait and See

Pasture spraying caused 2,4-D drift on your 18-foot blue spruces. Foliage is wilted and brown. 2,4-D is a growth regulator—it curls new shoots, browns needles, drops buds. Spruce is most sensitive in spring during rapid growth.

Outlook

Exposed conifers normally recover. No treatment needed—just avoid further drift. Monitor for new growth next spring.
