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 Strawberry Sundae hydrangea has never bloomed after 4 years. Please help me to get it to bloom before I dig it up and toss. We purchased The Original this spring, but it appears to be blooming white with hints of a very light blue. Was the plant mislabeled and actually a blushing bride or does this happen with The Original? I HAVE A BLOOMSTRUCK REBLOOMING HYDRANGEA AND IT SEEMS AS THOUGH THE BUDS HAVE DIED ON LAST YEAR’S GROWTH, BUT I DO HAVE NEW GROWTH COMING IN. SHOULD I BE WORRIED? What do you mean by mulching in the winter time to protect the early buds. My plant is 3 foot tall- do mean mulch the top of the dirt?
