My neighbor has 4 acres of old growth forest that is mostly oak. The property on the other side of his has been hit hard by oak wilt. It is moving our way. What is the best plan to stop its spread?

Several things you can do to help prevent oak wilt, prune only in winter, best time when the tree(s) is still dormant. Normally. the use of pruning sealants are not recommended because it interferes with the trees natural healing process. Oaks however, whether pruned or damaged by weather or whatever in the growing season, should be sealed so as not to attract the fungus carrying insect, which sometimes can happen within minutes after exposure.
Next is watch your trees regularly for anything unusual such as premature leaf drop
especially at the top, and especially if there are a number of oaks near each other. If oak wilt is suspected, you want to know positively as the disease can be
transferred to other oaks by underground root transmission.
