Delicious in salsa, guacamole, and various soups, cilantro is a versatile annual herb which is easy to grow indoors right on your kitchen windowsill. With a cilantro plant readily available, you can do quick clippings of this fresh herb seconds before you want to cook with it to get the best and strongest flavor. Growing cilantro indoors only requires a few basic supplies and minimal upkeep, so if you know you enjoy the taste of cilantro and will use it often, consider growing more than one plant so you'll always have enough on hand.
Fill the bottom of an unglazed, terra cotta pot with enough gravel to cover the drainage holes. Mix together a blend of two-thirds potting soil and one-third sand and use it to fill the pot up to the rim.
Plant a few seeds in the center of the pot half an inch deep. Cover the seeds over with soil lightly without pushing the seeds down and set the pot in a sunny window that receives at least five to six hours of direct sunlight each day.
Water to saturate the soil and continue to water the pot well every two days for the first two weeks as the seeds germinate. After the first two weeks, water the plant weekly by adding water until it begins to pool in the saucer.
Fertilize every two weeks with a 20-20-20 fertilizer according to the manufacturer's instructions. This should encourage foliage growth, giving you more leaves and stems to cook with.
Harvest the cilantro as often as you want to cook with it by snipping a stem 3 inches from the base of the plant. Use as many stems as needed for your recipe.
