Butternuts: good yield, needed fertilizer mid-season.
Cucumbers: good yield, but short season due to wilt/mildew. Distributed cucumbers weren’t as productive or disease resistant this season. Heavy feeder, give frequent fertilizer.
Delicata: hit with borers, but still reasonably productive.
Pumpkins: good yield despite borers, needed mid-season fertilizing. Mildew/wilt left a few small immature pumpkins.
Watermelon: seedlings almost wiped out by mechanical damage, only one melon.
Zucchini: seedlings were strong, plants hit hard by borers, but good, long yield from both varieties, try starting a second crop earlier than in 2017. Consider covering squash with insect screen until the first blossoms emerge to reduce chance of moths laying eggs. I agree that it would be good to try an insect screen experiment next year, possibly with not all of the plants because of space concerns.
