Spruce Galls

What are Spruce Galls?

Gall Adelgids cause wood galls to form on spruce tree branches. The galls, which change from green in early summer to brown in late summer, are pineapple-shaped and resemble cones.

Keeping Gall Adelgids in Check

• Water plants weekly when rainfall is less than one inch. Plants with an adequate moisture supply are naturally more resistant to insect and disease problems.
• Fertilize adequately to promote healthy plants.
