First time poster and here it goes! My question is about applying dormant oil. I had a customer call me about treating all his trees/shrubs. I was under the impression that the leaves needed to have fallen before applying dormant oil. My customer informed me that tg/cm always applied his DO at this time of year. Am i mistaken on having the leaves off the trees or was he misinformed? He pretty much told me in other words that tg/cl would know best being a big company and all. Whos right here and what should i do? Treat now or wait until the leaves fall. Any help on this would be greatly appreciated.
