Pruning Live Oaks

bjb817July 31, 2009

It's my understanding that other than the dead of winter, the dead of summer is the best time to prune Live Oaks. Is it true that the beetles that spead Oak Wilt aren't as common when it's this hot?

I also hear alot of conflicting advice about whether or not to use pruning paint. It seems that when you prune an Oak at one of the recommended times it's not as critical as if you do it at a less opportune time.

FWIW, there's never been any Oak wilt in the neighborhood to date.

I went to a seminar on oak wilt a couple of years ago and remember being told that cuts should be painted. In fact we were encouraged to paint wounds from branches that broke off in storms.

June 1st was given as the date after which it's okay to prune live oaks. As you said, summer is not as optimal as winter.

The presenter, who was a county extension agent, emphasized how important it is to plant other types of trees. That way if a neighborhood loses its live oaks to the disease, it's not left treeless. Plus, the disease spreads through the roots, too, so groves of live oaks are more at risk. Diversify!

You might want to check with your county extension office in case the recommendations have changed in past few years.
