For some reason I have little mildew trouble. My plants came from a neighbor who always has mildew.
Mine are in full sun.
I'm curious if anyone else prunes them. About the first of June, when they are knee high, I cut them in half. They are much bushier and don't get knocked down by heavy rain. They flower 2 weeks later than un-pruned ones.
Here is what one bunch looks like today, a couple days away from peak.
