I planted a Phlox paniculata 'White Admiral' not so long ago, it looked healthy and started to flower lovely white flowers but then gradually and suddenly the flowers shriveled up and fell off. Some of the leaves also started to get a lot of black spots around their edge. Not all the flowers have died,...yet, and the plant looks sturdy. Just curious if I'm doing something wrong. Couldn't find any info about it on this site so i decided to ask yourself.
I have an area of approx 1m X 4m in my garden that i want to place a flower bed. The area of that section of garden does suffer from bad drainage, the grass is very patchy and muddy to walk on when wet weather and the area is fully shaded. For my flower bed i'd like to be sure of what compost to use and what shrubs, plants, flowers grow well in these conditions and look very well. Low maintenance is also good, Im a beginner
