Oak Wilt, a deadly vascular disease that attacks all species of Oak trees, has been spotted in Hudson. Oak Wilt begins with wilting and browning in the upper tree canopy usually in mid-to late summer.

The disease can be spread over land by beetles that pick up fungal spores and carry them to healthy trees that have been recently pruned. It also can spread underground between neighboring trees through root grafts.

To help prevent the spread of Oak Wilt, avoid pruning Oak trees during the growing season (April 1 to Nov. 1) If pruning must be done, use wound dressing spray to seal the cuts.

Maintenance pruning should be done between Nov. 1 to March 31.

Trees also can be treated with preventative applications of a systemic fungicide which should be administered by an experienced, professional tree service.
