Mike from Eagle Creek, Or writes
At this time, should I wait for new growth to start or can I apply Crossbow at anytime of the year for blackberry bushes and vines? What part of the plant should I apply the Crossbow spray to?
Yes Crossbow Herbicide can be used to kill dormant blackberry bushes and vines. You would apply to thoroughly wet upper and lower stems including the root collar and any ground sprouts. Treat at any time when the brush is dormant and the bark is dry. Best results have been obtained with late winter to early spring applications.
