My black eyed Susans are growing quickly ( 12-18 inches now) and crowding out my Sweet Williams. Can I cut them back some to keep the other flowers from being smothered, or will that keep the BAS from blooming? I can just pull them up, but I think I need them for after the Sweet Williams stop blooming. If I do trim the back how tall should I leave them? If I cut them almost to the ground will they start over?? Thanks!
