(Best months for growing Coriander in New Zealand - cool/mountain regions)

P = Sow seed

  • 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 beside): Dill, Chervil, Anise, Cabbages, Carrots
  • Avoid growing close to: Fennel
  • Coriander/Cilantro
  • 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.

Can I grow cilantro indoors starting the end of July? Or, outdoors only?

You can plant cilantro all year; during cooler season you may start in tray/cups whatever method and plant out when it's about one inch tall. And if you have hot weather like us in California, you can direct sow the seeds anyplace in the garden, walk around and take a good look see, anyplace where there's shade, drop some seeds. I direct sow in my containers under the zucchini, around the tomatoes, under the marigolds (my marigolds are three feet tall), basically, anyplace in the shade, and remember, cilantro is cut and come again, pick often, because if you let it grow to coriander (to seed-can grow to five feet tall), then you can save the seeds after you let the plant dry out save the flowers because they become seeds. You can get hundreds of seeds from just one plant. Good luck!

Hi there I live close to the mountains in Central North Island and its quite a damp and cold climate. It also gets frosts here. Am wondering if its still okay to try grow Coriander in the garden (and cover on frosty nights) or if its better to grow inside due to the colder climate? Thanks

Hi there, I grow coriander in the garden over winter here in Christchurch where we get many frosts. This season my coriander has been frozen solid many mornings and has fared well, being even more prolific than in the autumn. I find corriander for me is a winter herb to grow. Good luck.

Check the planting guide here for cool/mountain climate. The big white P (planting time) in the green monthly boxes at the top of the page. If you have frosts from NOV to FEB then give it a miss.

I have been growing coriander in Middlemarch for the past three years, and it gets through the winter with no damage. Plants from seed direct sown in autumn, while small, have handled frosts of minus 12 as well as regular minus 5 degrees. All the late summer and autumn self sown seed is looking good. (Sept). I am constantly surprised by its easy handling of extreme winter temperatures. Using my own seed now from original Kings Seeds - 'Indian Summer' ironically.

-- sounds a very good idea, but I don't' have huge garden so basically I know what I am growing. I just grow what I like to eat. ( I wish if I can grow some chicken and meat but yah doesn't work this way) . well, they are very big parsley seed. they look like parsley seeds but they are probably 3 times as big. I will sow them next week and see in a few months what are they if they ever grow. ---------------

Gardening throws up many different things at us. The thing is to think about it from a different angle. All you can do is what you say, try planting them. I just tried planting seeds from a hybrid corn variety, they say they might not throw true to type. I had bicolour corn and yes I grew yellow corn, whitish corn and the yellow and white mix and I don't think it tasted as good as the hybrid. So I won't do that again. All about trying and learning.
