How to grow Coriander

Coriandrum sativum

Grows best in well cultivated soil in a sunny position. Cilantro is a short lived plant and is very prone to bolting – so having seeds started at different times to ensure a crop all summer long is best. Every two weeks sow the seeds so you will have a continuous cilantro crop. When flower heads appear cut them off to extend the life of the plant.

Cilantro grows best under cool conditions while hot weather encourages it to flower. Cilantro will withstand temperatures as low as 10 F°, which makes it an excellent fall crop.

Cilantro is ready to be harvested as soon as the plant is 4 – 6 inches tall, which can take 40 to 60 days after planting. It can take up to 120 days to produce mature seed (coriander).

If the older, outside leaves are harvested, the plant will continue to produce new foliage until it goes to seed.
Cilantro can also be harvested by pulling out the whole plant.
Some ethnic groups prefer to buy the plant with the roots intact.
Some Asian groups will use the roots in their cuisine – for example, in some Thai dishes.

It has been said that cilantro, once harvested, stays fresher longer with the roots left intact.

Growing Coriander from seed

This plant is best left not transplanted, so sow directly into soil outdoors after the last frost, or start indoors in peat pellets that can be directly planted without disturbing the roots.

Can be grown in containers.

Aim to sow 0.23 inches (0.6 cm) deep and try to ensure a gap of at least 5.85 inches (15.0 cm). Soil temperature should be kept higher than 21°C / 70°F to ensure good germination.

Transplanting Coriander

Best not to transplant – but if you do, make sure that you don’t damage the roots when moving.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Coriander is a hardy plant.

Harvesting Coriander

Cut the outer leaves first and let the smaller ones grow.You can harvest 2-3 times.The other way some people would do is just wait until they are big enough(not when flower) then they just take the whole thing out of the soil.

Note* If you pick too late it will flower and if it does then it will taste really bitter/sour.

Seed Saving Coriander

Let one of your plants flower and then when the seeds dries up you can just shake the plant a little then they will easily fall off / pick off the seeds over a paper bag.This is another way: let the seeds drop their seeds onto the soil on their own and then you can get more cilantro in just a few weeks but if you really just want the seeds just wait till they are dry and then pick the dried(the seeds should look yellowish brown color).

Seed viability is three years.
