I am a new gardener, so I recognize that I might be inadvertently killing my plants. I recently planted some garden phlox. I followed the instructions exactly and have been carefully watering them. Most are doing well, but a few seem to be dying on me. Some of the lower leaves are yellowing and drying out. Also, the flowers are dying and new buds are not forming. I have no clue what I am doing wrong.
A week and a half ago we had a big storm and all my perennials took a beating. Some of the phlox seem to have never recovered. They almost look like they are windblown....with the exception of those scary yellow and brown leaves.
I know that they can mildew but I looked up a picture of that and it doesn't look like what is happening.
I live in Georgia and we have had temperatures in mid-90's everyday. Can they get too much sun? Thanks for any help.
