Zucchini in a Zone 5 season

Zone 5 gives about 154 frost-free days. Zucchini needs roughly 55 days from sowing. That leaves about 99 days of slack, so there is room for a late start or a second planting.

How to grow zucchini

Sow zucchini once the soil is warm. One or two plants feed a family: pick young and often. In humid weather give the plants room, so the leaves dry quickly.
