Chances are pretty good that if you have ever grown cilantro you ended up with coriander seeds at some point. Coriander is the fruit or seed from the cilantro plant, which is also sometimes called the coriander plant. Letting cilantro plants bolt is how to grow coriander. The bolted plants send out flowers and seed in high heat. Growing coriander is easy and rewards you with a seasoning that adds exotic interest to your dishes.

What are Coriander Seeds?

Coriander is a seasoning. It is a hard, round little seed that is a light brown color. Coriander seeds are ground and used in breads, Indian and Middle Eastern foods, Latin and Asian cuisine and is also a component of pickling spices. Cilantro seed answers the question, “What is Coriander?” The coriander plant goes to seed if it is planted when summer is in full swing. If you want cilantro for the citrusy leaves, you need to plant it when temperatures are still cool in spring.

How to Grow Coriander

Plant seeds in late spring to early summer. The plant needs rich, well-drained soil and a moderate amount of water. Sow in a full sun location for best production in loam or sandy soil. Space the seeds 8 to 10 inches (20 to 25 cm.) apart in rows 15 inches (37.5 cm.) apart. By midsummer, the coriander flowers will appear as white lacy umbels. In a couple of weeks the plant will set seed. Neglect is actually the best method of how to grow coriander.

The formation of coriander seeds is dependent upon day length, sunlight and temperatures. Cilantro has a short growing season in hot climates and bolts when it is finished growing. Plants grown in mid summer will bolt in only four to six weeks due to the high temperatures. The varieties of cilantro seed that do not say they are slow to bolt will produce the quickest coriander crop. Slow to bolt means the plants will not form seed quickly and are more suitable for the cilantro leaves.

How to Harvest Coriander from Cilantro Plants

Coriander seeds need to be harvested before they drop off the plant. The pretty little flowers are attractive to honeybees and butterflies and turn into the seeds after pollination. The seeds are tiny and will be loose on the stem when ripe. Place a bag under the old flower stem and cut it off. Shake the stem into the bag and the ripe seeds will fall in. The seeds are best used as soon as possible but can be stored in a tightly sealed container.

How to Use Coriander Seed

Coriander needs to be ground in a spice grinder or mortar and pestle for use in cooking. You can also toast the seeds to bring out the flavor or wrap them with other seasonings in cheese cloth as a bouquet garni. The ground seed is most often found in curry powders such as Taklia, which is an Arab condiment, and garam masala. It is used in soups, stews, baked goods, desserts and as a rub on meats.

How to Grow Coriander

Cuisines around the world use coriander and cilantro, but the distinction between the two can be confusing. In the U.S., cilantro is a plant with leaves used as an herb. Coriander refers to the seeds of the cilantro, which are dried and used as a spice.

Coriander seeds have a warm, spicy citrus flavor, and are often used in Indian, Asian, Middle-Eastern, and Mediterranean dishes. Humans used coriander as long ago as 7,000 years seeds were even found in ancient Egyptian tombs.

Growing Conditions for Coriander

The cilantro plant grows best in cool climates and needs full sun with partial afternoon shade. Cilantro also grows well in a container placed in a sunny spot. The soil should be loamy to ensure proper drainage. Cilantro grows well next to basil, mint, potatoes, and caraway.

Planting Coriander

Plant seeds or transfer seedlings two weeks after the last frost. Sow seeds a half inch deep in rows eight to 12 inches apart. Seeds will germinate best in temperatures of 50 to 70 degrees Fahrenheit. When seedlings are well established, thin the plants out to 12 inches apart.

Caring for Coriander

Mulch around cilantro plants to keep the soil moist and discourage weeds from growing. Cilantro usually doesn’t need fertilizing, but a liquid fertilizer can be used on young plants. While waiting for the plant to bloom, take advantage of having fresh cilantro. It is rare for cilantro plants to have pest or disease problems.

Harvesting Coriander Seeds

When the cilantro plant blooms, it will grow a tall central stalk—this is called bolting. Two or three weeks after flowering, the cilantro leaves will start to brown. When they do, cut off the stalk and hang it upside down in a cool, dark, warm place until the plant has completely dried. If the seeds do not fall off when dried completely, put the plant in a paper bag and shake it to separate the seeds. Sift out the seeds and store in an airtight container. Seeds can also be removed from the stems and dried in an oven at 100 degrees until they are light brown. Some recipes call for whole seeds, while others call for ground seeds. Grind seeds right before using them for the best flavor.

The soil has to be neutral and rich in organic matter and most especially aged manure or rather a compost as it provides a steady supply of nitrogen among other trace elements and this way promoting vegetative growth.

The soil should be crumbly in texture as it is also important to helps the plant to grow well.


Planting

Coriander grows much better from seed, because it doesn’t like to have its roots disturbed. If you decide to plant seedlings, be careful not to disturb their roots too much when you plant them out.

Try to plant bought seedlings as soon as possible after you get them home and remember to give them a good, deep watering to help them settle in. When you plant your seedlings out, add a small amount organic bone-meal to each hole.
