The really hot weather of July and August is a good opportunity to give our oak trees a little trim. While it’s always a good idea to paint fresh wounds with an oil or latex paint, the heat at this time of year actually helps protect against oak wilt.
The form of fungus that spreads the disease and the insect that transports the spores of that fungus are nearly non-existent at this time of year.
When pruning, follow these rules to ensure proper pruning and prevent oak wilt:
Just keep in mind that if you lost the opportunity this summer, winter also affords the opportunity for more pruning. In fact, winter is the best time to prune all trees, except spring blooming trees.
Consult with a Certified or Licensed Arborist before doing any major pruning. Certified arborists may be found at the International Society of Arboriculture. Licensed arborists can be located by calling the City of San Antonio Department of Development Services, City Arborist.
