What Will Happen To My Landscape?

Gall infested tips cannot produce new growth the following year. Heavy infestations may cause minor retardation of tree growth and some distortion over time. Spruces drop their third and fourth year old needles every year. Should this inner needle drop catch up with a gall infested area, the entire branch will be lost.

What Can I Do About Spruce Gall?

Prune off the unsightly infested or previous infested tips. Chemical control must occur before galls begin to form. Because these sprays can cause injury to certain plants, read the label thoroughly before using and apply according to the directions. Apply insecticide treatments in fall, after the overwintering females have settled on the plants or, most commonly, in spring. Spring applications are most effective if made before the insects have begun to swell with eggs, which typically occurs in late April. Pruning away spruce gall can be a timely and unpleasant weekend activity.
