Will Roundup Kill Rose of Sharon?
Q: If I spray Roundup on the little plants around my rose of Sharon will it kill the tree?
A: It’s not likely. The sprouts are typically from individual seedlings that sprouted this past spring. They are not attached to the main plant. Be cautious though and examine closely those nearest the trunk. If they are sprouts from the roots of the mother plant, the weedkiller could travel from the sprout back to the original.
