When to Plant Beet in Colorado

Growing Beet in Colorado: Complete Guide

Beet (Beta vulgaris) is a crop that grows best when sown directly in the garden. Depending on your zone, the right time to direct sow in Colorado falls between February 27, 2027 (Zone 7a) and April 3, 2027 (Zone 4a), once soil temperatures are consistently warm enough for germination.

Because Colorado stretches across 7 USDA hardiness zones (4a, 4b, 5a, 5b, 6a, 6b, 7a), 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 55 days to maturity, Beet fits comfortably within Colorado's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Beet requires full sun to partial shade and regular (1 inch/week) moisture. Mountain-state gardens contend with short seasons and intense UV at elevation — cold nights can persist well into June at higher altitudes.
