When to Plant Zucchini in Vermont

Growing Zucchini in Vermont: Complete Guide

Zucchini (Cucurbita pepo) is a warm-season crop that needs a head start indoors before Vermont's last frost. Most Vermont gardeners begin seeds indoors around Sunday, April 12, 2026 and move transplants outside around Sunday, May 24, 2026, after the risk of frost has passed.

Because Vermont stretches across 5 USDA hardiness zones (4a, 4b, 5a, 5b, 6a), planting windows can shift by as much as six to eight weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 50 days to maturity, Zucchini needs the indoor head start that Vermont's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Zucchini requires full sun (6-8 hours) and regular (1-2 inches/week) moisture. In the Northeast, cool summers and moderate humidity can slow warm-season crops, so choose a sheltered, south-facing spot to maximise heat.
