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 Pleeeeease help. SOS… I need help because my hydrangeas continue to decline. It looks like they are spiraling just down now. I have attached today’s picture. They’ve been in morning sun/pm shade, moist, and last week I did add 1/2 oz of bone meal and 1/2 oz de-acidifier to soil. Thoroughly wet it afterwards. I’m trying not to give up…. help please. Will my hydrangea bloom with a couple hours of afternoon filtered sun? I am in zone 6. Can raspberry endless summer grow in full afternoon sun? I planted my Endless Summer Hydrangea about 2 weeks ago and it did really well for the first week and now it’s becoming less and less healthy. When I planted the hydrangea the tag said it would tolerate full or partial sun, so I planted it an area that receives full sun for about 10 hours a day. I also put a small amount of the fertilizer into the hole. I have watered it well daily since i planted it. The leaves and blooms are turning purplish and then brown and dry. I trimmed the dead leaves and blooms off very carefully and it’s continuously declining. I’m thinking I should transplant it to an area with more shade and am wondering if this would be ok to do if it’s done at a time of day that is not sunny and hot.
