When to plant cilantro in Hawaii
Most of Hawaii has no datable 32 °F freeze, so the cilantro dates here run on the Zone 11+ schedule the Plan Builder uses for heat-limited gardens: direct sow around Jan 1.
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.
Hawaii cilantro, by step
Zone 11+ planning dates, 2027 season. Each cultivar's own indoor lead time and days to maturity, same engine as the Plan Builder.
| Cultivar | Start indoors | Sow | First harvest | Days |
|---|---|---|---|---|
| CilantroSlow Bolt (Coriandrum sativum) | Direct sow | Jan 1 | Feb 15 | 45 from sow |
Tight means first harvest lands within two weeks of the median first fall frost. 96 of Hawaii's 97 ZIP codes have no datable freeze in NOAA's 1991–2020 normals, so these rows use the Zone 11+ planning average for the state's median zone (12b).

What these cilantro become
What Hawaii 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.
