How to grow Coriander / Cilantro (Coriandrum)

If planning to grow Coriandrum / Cilantro outdoors from the off it is best to sow out the seed every two weeks at a depth of 1 cm from the last frost of spring until the autumn.

Coriander likes to grow in an area that has plenty of sunlight, and prefers a rich soil of pH 6 to 7.

If you plan to grow seedlings of coriander indoors then they should be grown in peat pots and prepared about 6 to 7 weeks before you plan to put them out, from early spring onwards.

Alternatively you can grow them indoors all year around.

Harvesting Coriander / Cilantro

Both the leaves and seeds of Coriandrum can be used in cooking. Coriander seeds should be harvested by covering the stalks and seeds in a paper bag, tape the bottom of it, and allow the coriander seed to set.
