Green Bumps On Mulberry Leaves

Question

My neighbor just hacked away at a wild non-fruiting mulberry tree adjacent to my property. She insisted the green bumps were insect eggs. I don’t think they are since not all leaves have them and the leaves were mot chewed by anything. Actually is was a really healthy looking tree. She destroyed half of the tree. What are the green bumps that look like small peas on the underside of the leaves. What can I do to undo some of the damage she caused. That is after I clean up the mess of leaves and branches.

Answer 1

She is right. They are insect eggs, and even mature specimens on occasion.

Galls are, usually, harmless in most cases, though.

Mulberry trees will really enjoy a thorough pruning, so she did no harm in doing so.
