Growing Squash in Kentucky: Complete Guide
Squash (Cucurbita moschata) is a crop that grows best when sown directly in the garden. In Kentucky, the right time to direct sow is around Wednesday, March 4, 2026, once soil temperatures are consistently warm enough for germination.
Because Kentucky stretches across 4 USDA hardiness zones (6a, 6b, 7a, 7b), planting windows can shift by as much as two to four 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 90 days to maturity, Squash fits comfortably within Kentucky's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.
Squash requires full sun (6-8 hours) and regular (1 inch/week) moisture. Most of Kentucky receives adequate sunlight during the growing season, though gardeners in humid eastern regions should watch for fungal issues and ensure good air circulation.
