Powdery mildew – grow resistant varieties where possible
Squash vine borers – grow resistant varieties where possible, experiment with non-surgical methods
Cucumbers: did well, excellent yield (many dozens) – give a bit less real estate, grow pickling type on arbor next year
Pumpkins: disappointing yield (@ 12), lots of powdery mildew
Watermelons: good yield (@ 20), some vine withering, a few rotted and a few were harvested too late
Winter Squash (Delicata): disappointing yield (@ 12), lots of vine borers – give more space?
Zucchini & Zephyr (Summer Squash): good yield, compact plants worked well in space
