S = Plant undercover in seed trays. P = Plant direct in garden where they are to grow.


  • Easy to grow. Sow in garden. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 50°F and 77°F. (Show °C/cm)
  • Space plants: Thin to 18 inches
  • Harvest in 30-45 days.
  • Compatible with (can grow in same bed): Dill, Chervil, Anise, Cabbages, Carrots
  • Avoid growing in same bed: Fennel
  • Coriander flowers

Broadcast sow and thin to 45 cm apart. Grows to about 60cm. Harvest 30 -45 days A half-hardy herb with feathery leaves. . Grows more reliably from seeds as coriander is liable to bolt to flower and seed when seedlings are transplanted.

Coriander is frost tender but it doesn't like extreme heat. So in temperate zones grow coriander during summer, in sub-tropical/tropical zones grow it during the cooler season.

Needs a sunny spot and mulch to prevent drying out. Keep very well watered. If they dry out, then they will bolt to seed. Plant in successions (planting new seed every few weeks) to get a continuous supply.

Culinary hints - cooking and eating Coriander

Use the leaves to flavour hot meals or add fresh to salads.
The seeds can be dried and ground up for curries.

Coriender is excellent for flavour. My wife loves so I grow it in my garden to keep her smiling. This year in mid September it stated giving seed. I did not uproot them. let them grow and mature seed. On the other side i seed coriender from my previous seed stock, it was. excellent germination. plants were growing very well. I was aware that October will be harsh. My tomato plants were the first to shed leaves. Fruits were rottenning . I took old hose pipe and cut them in 5 feet pieces. To give strength to the soft pipe I inserted bamboos sticks in them and then made the hoops over the crop. I covered the rows of coriander with pipe hoops and plastic sheets of painter. I could able to save and survive my coriender tender plants. I measured temp of in and out on very sunny day. It was 29oc inside and it was 22oc out. I told my daughter my plants are burning inside i must ventilate. I opened the ends of hoop also lifted sides of plastic. My question is when to ventilate, how often, what should be the thickness of plastic sheet.Is thickness is important. yes, I forgot. when my plants matured in september 15, I seeded the seed in soil to if they germinate or not My all seed germinated. so I concluded the coriender seeds does not have any dormant or dormancy period before sowing.

I love coriander, I have been told that it has phytochemicals that reduce the feelings of guilt in people. Can anyone tell me if this is at all true?

It is true, coriander is high in many vitamins and minerals, folic acid, 5-hydroxytryptophan, and is one of the highest natural sources of S-adenosyl-L-methionine. Because coriander is generally not cooked for long these chemicals are not degraded as they often are in other foods. Each of these on their own have been proven to reduce the feelings of guilt, but when combined like this they appear to have a far greater impact.

I too do that with supermarket shallots (keep the ends and plant them out - into a pot - and they do fine). I'm also wanting to try it with coriander roots (from supermarket). Will keep you posted on the results of the experiment.

Post a question, comment or tip about Coriander

I have tried many times to grown coriander with no luck. I keep persevering because I like it so much. Every time I plant it, it goes to seed within a very short time without giving me a crop. Have asked the "experts" who give me various bits of advice i.e. not too much water, not too much sun etc etc. We get heavy frosts in my area. How can I stop this plant from going to seed?
