How to grow and keep Coriander happy
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. 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.
It has been said that cilantro, once harvested, stays fresher longer with the roots left intact.
