Use of dormant oil on fruit trees
I have about a dozen fruit trees and two of them had problems last year that are treatable with dormant oil. I sprayed once about 2 weeks ago, and now the trees are starting to bud. I'd like to do a follow-up spraying. I have heard two things about dormant oil: 1) you can spray any time, and 2) you shouldn't spray when they are budding. Anyone care to comment on which is correct?
