Hi, Lucy. My parents grew sun chokes for years, and sometimes they did get quite a bit of PM on the leaves. They were often pretty crowded ( thinning was never Dad's strong suit), which of course probably contributed. But in the autumn, we just went ahead and dug the tubers up anyway, and always had plenty. They weren't grown near anything which we were worried about sharing the PM, so just didn't worry too much about it. I don't know what to do to limit it, but I suppose that I may get more experience soon, as I am planting some sun chokes here at my place this year, and here we do have a tendency for PM on curcurbit crops. I will let you know how it goes. Did you cut down your sunchoke plants to avoid the PM spreading to other crops? Is there a space on your land that is far enough from other PM susceptible crops that you can afford to just let them finish out the season, even with the PM on their leaves?
