When to plant cilantro in Delaware
Direct sow cilantro 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 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.

What these cilantro become
What Delaware 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.
