When to plant carrots in Delaware
Direct sow nantes carrot around Mar 24 — the Delaware statewide median, counted from a last spring frost of Apr 7 across 68 ZIP codes and 12 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.

What Delaware 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.
