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 Did cutting flowers last year in the fall to dry in vases cause my hydrangeas to not produce any flowers this year? My endless summer hydrangea is looking a little bit wilted. Some of the flower buds are bending down. I felt the soil and it is moist. We had a thunderstorm last night with strong wind for about 1-2 hours. Could that be the reason why? Is there anything I should do at this point? Thank you and any insight is appreciated:) Do any hydrangeas do well in moist soil? I planted three The Original Hydrangeas and one is not flourishing like the other two. It does get more sun 6-7hrs a day starting 1st thing in morning. It is flowering but some of the leaves are turning brown. I don’t see any bugs. Live in eastern Virginia. Used peat moss and Holly Tone when planted.
