Q: Hello, I attended one of your sessions at English Gardens this spring and you mentioned a product which should be used in the fall when the root systems for next year are growing for the pest "bishop's weed". Could you please provide the name of this product or chemical? Thank you!
Jill, The product is Roundup. Read the instructions carefully. It will kill or damage any plant it touches and this includes trees and shrubs. Happy Yardening, Nancy
