Best Tomatoes to Grow in Utah

Zone 5 offers a sweet spot for tomato growing – long enough summers to ripen full-size varieties, but short enough that you need to choose wisely. With your 155-day growing season stretching from late April through early October, you have excellent opportunities for both determinate and indeterminate varieties, but late-season types like some heirlooms can push their luck against that October 5th frost date. The key challenges you'll face are getting plants established after that final April frost risk and ensuring your longer-season varieties have time to produce before fall's arrival.

When selecting varieties for Zone 5, prioritize disease resistance and days to maturity over exotic varieties that might not finish. Look for tomatoes that mature in 70-85 days for your main crop, with some early varieties (60-70 days) to get that first harvest by mid-July. The varieties I've selected below have proven themselves in Zone 5 gardens – they handle the temperature swings of late spring, produce reliably through summer heat, and most importantly, they'll give you a solid harvest before frost threatens your plants.
