leaf burn on Hedychium?
I have a butterfly ginger that is shaded in the morning and late afternoon, but unfortunately gets full sun for a few hours around noon. Anyway, the bottom leaves, slowly around the edges first turn yellow, then brown, and it just slowly moves in from the edge. I've already removed four or five leaves from the bottom up, and it just keeps moving up. It almost is like a salt-burn...Is it from the hot sun? Or maybe from the sandy, probably alkaline soil that I have? I'm thinking it would prefer more peat and organic matter in the soil. Thanks for any advice.
