Tips for how to grow cilantro from seed in a pot indoors or out.  Find instructions for how to plant cilantro seeds in a pot and for how often to seed cilantro.

Cilantro, also called coriander, is easy to grow once you know your technique. Cilantro grows quickly and should be succession seeded every 2 or 3 weeks to maintain a constant, fresh supply for your household. In warmer climates cilantro can be grown year round and continuously seed itself. In cooler climates, like my zone 3 growing climate, cilantro will go to seed in the fall and you may have an abundance of small plants all ready for harvest at the same time next year! I have found some varieties do not form proper seed heads. I'm guessing these are hybrid varieties. If you have a heritage variety you will be able to easily collect the brown round seeds off the plant in the fall. You can also choose to let the seeds fall but you may end up with a problem of out of control cilantro! Once cilantro is cut down for use the plant will put more energy into seed growth and you will not have much more leaf growth. That is the reason the frequent seeding cycles are beneficial.

How to Plant Cilantro in a Pot

You can plant cilantro seeds as close as one one or two inches apart for young harvest. I use a 6 inch round pot and place about 10 seeds on top of the soil, then cover those with a 1 cm. layer of soil. The seeds take 7 to 10 days to germinate and month to maturity for leaf harvest. Seeds can be soaked for 24 hours prior to planting them to encourage quicker sprouting. Keep soil moist until plants germinate (or sprout).

When to Plant Cilantro Seeds

Cilantro can be planted in a pot at any time! I like to plant my cilantro seeds as soon as I have my indoor plants started in the spring (the end of January). These first cilantro seeds are grown to maturity indoors in a pot for a handy kitchen supply. If you have indoor grow lights you can grow cilantro all through the winter! (Check out My Favourite Products for Growing Indoors!) When growing cilantro in your garden during the hot summer months the plant has a tendency to bolt. To prevent this plant your cilantro in partial shade in a cool part of your garden.

I have used both these seed varieties to grow cilantro from seed in a pot indoors or outdoors.

Coriander - Cilantro Seed

Coriander is the name of the seed while cilantro is the name of the leaf. To save the coriander seeds, allow the seeds to dry and turn brown on the plant prior to harvesting the seeds. These seeds can be used to flavour food or for next year's cilantro planting! For more on saving seeds check out A Beginners Guide to Saving Seeds.
