I am concerned about the spread as well. I dug up as much of a spreading tree as possible but I need to kill the roots. If I spray directly onto roots and around soil, How long must I wait to plant vegetables?
Crossbow Herbicide will stay in the soil and could veggies for up to 2 years. It's possible you could use Tordon. We recommend to contact Dow 800-992-5994 option 4 the manufacturer of both products for the best one to suit your treatment.
