Growing Cilantro In Containers



In a previous post, I discussed basic cilantro/coriander growing techniques but didn't address the option of growing cilantro in a container. Cilantro has a taproot, which means that it roots deeply. This makes it a poor candidate for transplanting, and pretty much also means that it needs a deep pot. The other option is to grow it in a soilless medium like a hydroponics setup.

Growing Cilantro Indoors


I've kept cilantro indoors successfully  in a southern facing window using a 12 inch pot planted out with shallow rooted herbs like chives. That way I maximize the use of the large pot and still manage to give the cilantro what it needs. Everybody ends up healthy and happy.

Cilantro likes a sunny location, but avoid placing it right next to a window in high heat regions, especially during the hottest part of the summer.  The combination of light and heat will likely burn cilantro's delicate leaves.  Placing plants a foot or two from the windowpane is a good precaution. If heat from the window is uncomfortable for you, it will probably damage plants that aren't desert hardy (like cactus and succulents). 

If you try keeping plants in a less light intensive spot, like in an eastern facing window, make sure you can see the shadow of your hand when the light's shining. Bright light for around six hours a day should be adequate.

Grow Cilantro Indoors
Prefer a quality potting mix, and keep the plants evenly moist but not wet.  Cilantro will tend to get leggy, so harvest a third of the top growth at a time after young plants reach 6 to 8 inches. Harvest again when that much grows back.  You'll be able to harvest multiple times throughout the summer months.


Potted Cilantro Outdoors


To keep cilantro on my deck in summer, I mulch the plant well, including a layer of shredded newspaper. I also improvise a water reservoir using a two-liter bottle. Here's how:

I plug the opening at the neck of the bottle with a small piece of kitchen sponge, cut out the bottom of the bottle and then upend it into the pot. When I fill the bottle with water in the morning, it keeps the soil moist during the hottest part of the afternoon.

Another problem with cilantro is that it's prone to bolting. To keep leaf production up and delay the onset of flowering, pinch back flowers before they fully develop and harvest leaves regularly. There are a few other bolting avoidance tips you can follow, too. My post: How to Keep Plants from Bolting will tell you more.

  1. I love Cilantro, it smells and taste good too. I will try your hydroponics setup, hope to get a change harvesting indoor herbs soon.
    Cheers!

  2. Can you tell me how to prune the different types of lavender. I am growing several kinds in one bed. It is very hot here. The winters are usually pretty mild (no snow) and we may have two or three days of freezing weather a coupld of times per winter.
