Question WHEN IS THE BEST TIME TO PLANT CREEPING PHLOX? Answer Creeping phlox is a tough plant! You can plant it either spring or fall. If you plant it now, you will be able to enjoy it early spring when it flowers. Tags: CareDesignFAQProjects Related Questions My Blushing Bride has so many small flower heads. It may be preventing it from growing large flowers. Should I prune some of the small heads? I bought a crabapple tree about two weeks ago and it has still to show any new growth. How long does it take to show any and how do I know it is actually healthy? How do I dead head your roses? We just planted 3 of them. Thank you. It just snowed 6” on my Easy Elegance Rose bush. Was I supposed to cut back, cover or remove from the ground for winter?
