When to Plant Beefsteak Tomato in Utah

Growing Beefsteak Tomato in Utah: Complete Guide

Beefsteak Tomato (Solanum lycopersicum) is a warm-season crop that needs a head start indoors before Utah's last frost. Most Utah gardeners begin seeds indoors around Sunday, March 14, 2027 and move transplants outside around Sunday, May 9, 2027, after the risk of frost has passed.

Because Utah stretches across 9 USDA hardiness zones (4a, 5a, 5b, 6a, 6b, 7a, 7b, 8a, 8b), 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 85 days to maturity, Beefsteak Tomato needs the indoor head start that Utah's growing season requires. Starting indoors ensures you have strong transplants ready the moment outdoor conditions are right.

Beefsteak Tomato requires full sun (6-8 hours) and regular (1-2 inches/week) moisture. In the arid Southwest, intense sun and low humidity mean irrigation is essential; mulch to prevent rapid soil moisture loss.
