My phlox is in full sun so that may be the problem. As far as fertilizing, I have used that new product for Miracle Gro that you shake on and it's time realeased for 3 mths. I have given all my
plants lots of water every day because we have been going through a dry spell. As far as the soil requirements, perhaps I should add some manure and peat moss although the
plants around it are thriving. Anything is worth a try. I may divide the
plant after it
flowers to give it more air circulation. Thanks guys for your advise.
