Rolled Up Edges of Redbud Tree – Critter
Q: What critter would roll up the edges of my redbud tree leaves?
A: It’s the work of a redbud leaffolder. A small moth lay eggs on the edge of a leaf. When they hatch, the grubs fold the edge of the leaf over themselves for protection. They feed on the leaf and it dries out. When many leaves are affected, redbud trees are very unattractive. Since the damage is usually sporadic on trees, you could choose to let natural predators do most of the work for you. If your tree is in a prominent position, spray it with Bacillus thuringiensis (Caterpillar Attack, Caterpillar Killer, etc) in late April and again in late May.
