I have a large lilac bush that is surrounded by Canadian thistle. If I spay the thistle next to the lilac bush, will it hurt my lilac bush?
Q4 Plus Turf Herbicide can potentially cause harm to desired plants like lilac. I would carefully spot spray areas near the lilac bush, and also wrap the lilac bush in a large garbage bag to protect it from any drift spray.
