Thanks, Arlyn. My raised garden is very fertile. I grow great vegetables there, year after year. The garlic is my "cash" crop and I sell all that I grow. I like my iris flowers but these plants are not what I grow much off. I am in the tropical plant business and have over 1000 tropical plants, mostly orchids. If the irises had not been gifted to me last year, I would have none of them. I will take all your advice, and just leave them be.
