I am pulling my hair out on this one. This is beebalm. It was very green when I brought it home. Several of my perennials in my new garden are turning weird colors. The leaves started getting pale and then yellowish then orangish, then PURPLE! I believe my Ph is normal. I am doing some spoil tests [very difficult] and what I know so far is nitrogen is very low. I know that can cause leaves to yellow, but PURPLE? ...will post another photo of a young tree that is doing the same thing.
