Hi, y'all. I'm just following along. I know nothing about the life cycle, etc. (Ok. I did take basic biology.) I worry that now that I'm growing milkweed, gregg's mistflower, bronze fennel and other such stuff, that I won't have enough for these guys to eat. I read somewhere that it can happen. Since I only have a small backyard perennial bed, I don't want to be the temptress who then starves her guests to death. Is there any way to know?
