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.

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 Alaska's ZIP codes resolve to; 16 of 146 ZIPs have no datable freeze and are left out.

What Alaska cilantro need

SeedsThe cultivar decides the sauce. Everything downstream is damage control.
  • 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.

StartSoil temperature and light intensity, indoors, weeks before your frost date.
  • 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.

GrowRoot volume, nutrition and structure. Where most home crops actually fail.
  • 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.

ProtectFrost, hornworms, aphids, and the fungal pressure that follows a wet July.
  • 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.

HarvestTiming, handling, and weighing what you actually got.
  • 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.
