How to Start a Vegetable Garden from Seed in Utah

When to Start Seeds in Utah

Utah's growing zones range from 4b to 8a. Start seeds indoors 6-8 weeks before the last frost date. In northern Utah, this means starting seeds in March. In southern Utah, you can begin in February.

Choosing the Right Vegetable Seeds

Select varieties suited to Utah's climate. Tomatoes, peppers, and squash thrive in warm summers. Leafy greens and root vegetables do well in spring and fall. Look for short-season varieties for high elevations.

Seed Starting Indoors

Use sterile seed-starting mix and containers with drainage. Plant seeds at the depth specified on the packet. Keep soil moist and warm (65-75°F). Provide bright light once seeds germinate, using grow lights if needed.

Hardening Off and Transplanting

Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days. Transplant after the danger of frost has passed and soil temperatures have warmed.
