Sow cumin in a sunny bed that already drains. [1] Cover the seed about a quarter inch, or up to a half inch in a loose bed. [2] The taproot does not like a move, so sow it where it will stay. [3] Sun and watering after planting are on How to Grow Cumin.

When do I plant cumin?

One to two weeks after the last frost, once nights stay above about 50°F. Sow it where it will stay.

How to plant cumin

Sow after frost, cover the seed about a quarter inch, keep the seedbed moist until it sprouts, then thin to about 4 to 8 inches.

  1. Choose a full-sun bed of loam that drains. Work in a little compost if the soil is heavy clay, so water does not sit on the roots.
  2. Soak the seed for about eight hours if you want faster sprouting, then sow in groups a few seeds together. Cover about a quarter inch. [4]
  3. Keep the seedbed moist until it sprouts, usually in 7 to 14 days. Do not let a crust dry out over the seed.
  4. Thin when seedlings are about two inches tall so plants stand about 4 to 8 inches apart. Leave them close enough that the stems can lean on each other.
  5. If the summer is short, start the seed four to eight weeks before the last frost in a biodegradable pot, then bury that pot whole once nights stay above about 60°F. Do not tease the taproot out of a plastic cell.

How far apart do I plant cumin?

Thin seedlings to about 4 to 8 inches. Sow them close enough that the slender stems can hold each other up.

What fails at planting

Moving a seedling with a long taproot is the main reason a transplant sulks. Do not bury the seed an inch down, and do not sow into cold soil that still holds frost.

If you bent the taproot, sow a fresh row after frost, barely covered, and leave it where it is.

FAQ

Should I start cumin indoors and transplant?

Only if the summer is short. Start in a biodegradable pot and bury the whole pot once nights stay warm. Do not slide a seedling out of a plastic cell and bend the taproot.

Can I grow cumin from grocery-jar seeds?

Sometimes, if the seed is fresh and was not heat-treated. Garden seed is the surer start. Sow it where the plant will grow.

Can I grow cumin from cuttings?

No. Sow seed. A cutting is not a reliable way to start this herb.
