Brown leaves on tops of Lilies
I have about 20 lilies in a small garden on the southeast-facing side of my house. They are grouped together and almost all are doing fine except 3, they just started getting brown leaves near the tops of the stalks. Can anyone tell me what is cauing it and what I can do to stop it? The soil is mostly clay though I added peat moss and topsoil to this garden before planting anything to try to alleviate some problems.
