Plant Cilantro for Flavor This Spring

by | Feb 18, 2021 | Gardening | 2 comments

Even though we are still in the winter months, now is the right time to plant cool weather herbs. The most popular of these is cilantro (Coriandrum sativum), the source of flavor for many Southwestern dishes such as pico de gallo, tacos, burritos, and…just about anything Tex-Mex.

Unlike heat-loving basil, another herb annual, cilantro is happy germinating in cool weather. For those of us living in the southern U.S. this means we need to treat it like a two-season annual.

The first season for cilantro begins in late February. Planting it now means you will be harvesting flavorful leaves during the warming spring days. Then when temperatures begin to exceed 90 degrees it switches gears, sets seed, and dies. You may have heard some gardeners call this “bolting”. By the Fourth of July it is ready to be pulled up and discarded. then after the heat of summer is past (about Labor Day), you can plant cilantro again for a second season of flavor.

Buying the Right Cilantro For You

These fresh green leaves may look like parsley but they are are cilantro, an herb with a flavor kick.

To maximize the amount of harvest from your young herbs look for “slow-bolt” varieties, which will increase production by two to three weeks. Recent introductions include ‘Calypso’ and ‘Marino’ cilantro. If you prefer a milder flavor in your foods, look for ‘Confetti’ cilantro which also has more finely divided leaves.

Essential Planting Guide For Herbs

When purchasing cilantro at the local nursery, take care not to confuse this herb with culantro (Eryngium foetidum), a Caribbean herb with prickly, strap-shaped leaves and a flavor similar to but definitely stronger than cilantro. You won’t be happy with the results – trust me.

Growing Cilantro From Seed

Cilantro seeds can be sown in late winter directly in the soil where you want them. Allow two weeks for seeds to germinate. Thin seedlings so they are 8 to10 inches apart. Whether you buy plants or seeds, take care to avoid damage to the central taproot if you transplant them. Cilantro is in the same family as carrots and will not be happy if it loses its central root. Water regularly and fertilize about every six weeks to encourage healthy growth.

The seeds of the cilantro plant are also known as coriander, a warming spice.

You can begin harvesting cilantro about five weeks after transplanting. Leaves are clipped from the outer area of the plant to allow the inner core to mature. Continue harvesting until the central flower stalk appears. Once that happens, the leaves become less flavorful.

Even though our gardens are still cold and mostly dormant, it’s time to start thinking about spring. Next chance you get, buy some cilantro seeds or plants and get your herb garden going now.

    My cilantro was amazing this winter. It was growing strong right before the arctic event happened in a dish type pot on the ground. I had harvested some right before the snow came. As the deep freeze descended, I assumed it was gone. After the snow, below zero temperatures, sunshine and thaw, I was totally amazed that the plant was not mush. There was snow partially covering the plants so I assume this provided enough insulation for it to survive. Even the exposed green leaves suffered minor frostbite. I’m still amazed and those same plants are ready for another snipping. Is this unusual?

      Cilantro is a cool-weather herb unlike the other popular annual, basil. In freezing weather, basil will die – end of story. But plants like cilantro may lose their above-ground leaves but rejuvenate from the underground root crown. Good for you!
