When to plant cilantro in Utah
Direct sow cilantro around Apr 21 — the Utah statewide median, counted from a last spring frost of May 5 across 295 ZIP codes and 136 NOAA stations.
The rule: Direct sow in 60–70 °F soil, a short row every two weeks from four weeks before the last frost until the heat arrives, then again from late summer.
Utah cilantro, by step
Statewide median last frost May 5, first fall frost Oct 10, 2027 season. Each cultivar's own indoor lead time and days to maturity, same engine as the Plan Builder.

|---|---|---|---|---|
| CilantroSlow Bolt (Coriandrum sativum) | Direct sow | Apr 21 | Jun 5 | 45 from sow |
Tight means first harvest lands within two weeks of the median first fall frost. Statewide dates are the ZIP-weighted median of every NOAA 1991–2020 station Utah's ZIP codes resolve to; 3 of 298 ZIPs have no datable freeze and are left out.

What these cilantro become
What Utah cilantro need
Cilantro / Coriander Seed
Bolts in a heartbeat and there is nothing you can do about it — so you succession-sow instead of fighting it. Non-negotiable in salsa verde and zhoug.
Organic Seed Starter Potting MixMust have
Seed-starting mix is not potting soil with a nicer label — it is finer, lighter, and low in nutrients on purpose, because a seedling's first roots want air and moisture, not fertiliser.
Ocean Forest Potting SoilMust have
Pre-charged with enough nutrition to carry a transplant for its first month without feeding, which is exactly the window when most container plants stall.
5-Gallon Fabric Grow Bags, 5-Pack
Fabric pots air-prune roots and drain faster than a plastic pot can, which is the entire reason container tomatoes fail. Five gallons is the honest minimum for a pepper; a tomato wants ten.
AG-30 Frost Protection Row Cover
AG-30 buys roughly 6 °F of frost protection while passing about 70% of light — enough to carry a crop through an early-October cold snap that would otherwise end your season two weeks short.
6" Micro-Tip Pruning SnipsMust have
Ninety percent of sauce-garden cutting is snipping a pepper stem or a basil node, and a fine-tipped snip does it better than any pruner. Pulling peppers by hand tears the branch.
