Growing cilantro indoors may be as successful and flavorful as raising cilantro in your backyard if you give it a touch of extra care. You can have immense success in growing it inside with just a little extra consideration.
When growing cilantro indoors, you ought to supply it with extra nutrition than when outside. Because the roots of the plants are restricted and can't access the needed soil for nutrients as it would in an outdoor garden. You should use a standard garden mixture with some extra sand in it to allow for proper drainage. Also, add a liquid fish emulsion or chemical fertilizer such as 20-20-20 to add in the extra nutrients required. Use fertilizer at one half strength every other week when the plants are actively growing.
Watering the cilantro thoroughly is more imperative than watering frequently when growing cilantro indoors. Water until the water comes out of the drainage holes at the bottom of the container. Check the soil frequently, even daily. But, only water cilantro growing indoors when the soil is totally dry to your touch. During the summer months this may be more often than throughout the winter months depending on the moisture of your house.
It is vital when growing cilantro indoors that the plant has access to full sun 4 to 5 hours each and every day. Indoors, growing cilantro will be more successful if you use a growing light.
Cilantro is a short lived herb, even under the best of growing conditions. Pruning it regularly will help in delaying bolting, but cilantro will bolt sooner or later no matter how much or how often you prune it. You should plant new seeds about every six weeks to keep a steady supply during all of the growing season.
