Question From: Littleton, Colorado, United States
Q: Broad leaf lindon tree: leaf presents w/ vertical green growths w/ red tips. When crushed open no obvious worm or eggs visible to naked eye
A: I believe they are galls. They will not harm the tree, so ignore them. However, to be sure I would take some samples in to a nursery that specializes in trees for another opinion. Best And Happy Yardening, Nancy
