weed control (spraying timelines) #942201

Asked August 11, 2026, 9:37 PM EDT

I have future Christmas trees and a lavender field which are both sprayed during the season for weed control. Is it beneficial to do a fall spraying to possibly get ahead of the next season of weeds?

Expert Response

Yes, it would be very beneficial to do a fall herbicide application to control weeds prior to planting Christmas trees.  A broad spectrum post-emergent herbicide would be ideal.  A product such as glyphosate would a possible option that would fit in that category.  More information on weed control options in Christmas tree production can be found here: Weed Control in Christmas Trees - E3237 - Christmas Trees Also, Bill Lindberg is the MSU Christmas tree Extension educator and can help address more questions,<personal data hidden>.
