When to plant carrots in Oregon
Direct sow nantes carrot around Mar 28 — the Oregon statewide median, counted from a last spring frost of Apr 11 across 398 ZIP codes and 155 NOAA stations.
The rule: Direct sow two weeks before the last frost and keep the top half-inch of soil damp for the 14–21 days it takes to germinate.
Oregon carrots, by step
Statewide median last frost Apr 11, first fall frost Oct 30, 2027 season. Each cultivar's own indoor lead time and days to maturity, same engine as the Plan Builder.

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 Oregon's ZIP codes resolve to; 30 of 428 ZIPs have no datable freeze and are left out.

What Oregon carrots need
Scarlet Nantes Carrot Seed
The carrot that makes a fermented habanero sauce work. It brings sweetness and body so the sauce has texture without thickener and heat without being one-dimensional.
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.
Rapitest Soil Test Kit
In-ground growers are guessing until they test. pH outside 6.0–6.8 locks nutrients out no matter how much fertiliser you add, and no amount of feeding fixes that.
3-in-1 Soil Moisture / Light / pH Tester
Used for one thing — is the root zone actually dry six inches down — it prevents both halves of the most common container failure. Ignore the pH scale on it entirely.
Garden Harvest Basket with Tool Caddy
A harvest basket that doubles as a colander means the hose rinse happens in the garden, and the dirt stays outside. On a 20-pound tomato day that is a genuine time saving.
