Lisa from Portland, Or writes,

How long before I see results with Crossbow Herbicide?

How long will it be before I know if my treatment with crossbow to eradicate emerging blackberry plants is effective? If they don't wither and die according to product specifications, how long before I can re-apply?


It can take two weeks or more for a burn down with  Crossbow Herbicide.  You can reapply 30 days after application if needed. .
