Title: Oak leaf blister on live oak tree
Answered by: Joe Marcus

QUESTION:

Our live oak tree has a bad case of oak leaf blister and is really in need of a trim. Will it hurt the tree if we have it trimmed now? Thanks.

ANSWER:

Oak Leaf Blister is more of a nuisance and an eyesore than an actual threat to infected trees. It would be better to wait until winter to trim your live oak, but if you do prune it now be sure and seal the wounds with a latex-based pruning paint to minimize the hazard to your trees from Oak Wilt infection.
