So Im seeing the tops of my shade leaves turning purple and yellowish. I think this is just a natural part of the life cycle, but I do have a question about another plant. The leaves turned yellow when it reached about 4 feet. It kicked out some flower, and just stopped growing. Most of the leaves turned yellow, but I could see no signs of borers, bugs, or diseases. It has been fed exactly the same as the other plants, one day it just locked. wondering if I should just take it out of the garden but it hasnt affected any of the other plants around it, should I just let it roll?
