Judy - The spores start on the tips of the leaves? I'd honestly never noticed that. I usually start seeing the rust along the base of the leaves and it seems to spread from there. It will cover the leaves within a week. I didn't see any spores on most of those plants. Some yes has some minor spores along the base and middle of the plant, but I didn't see any spores on the tips. The tips looked as green and nice as the rest of the plant. I wonder if these 2 new garden beds has anything to do with the lack of rust being that these are the very first plants grown in them?
