How To Grow Catnip Indoors

Last Updated On: January 19, 2021

Catnip is a fantastic plant to grow indoors, and even better when you have a feline friend to share it with. Catnip is a relatively easy plant to grow, and does so quickly. While it can be grown both indoors and outdoors we’ll be focusing primarily on indoor and container growing. Many of these tips however are applicable regardless of where you grow. With that in mind, let’s jump right in and learn how to grow catnip indoors.

Potting

Catnip can be potted in a wide range of containers and do perfectly fine. It can be contained to a small windowsill container, but will quickly grow to fill large containers as well. Look to purchase a gardening pot of the size of plant you wish to grow and the catnip will grow to fill it.

When potting, you can start with seeds or seedlings, but you also have the option to take cuttings. This is a great way to start a fresh plant each year as you can simply take a bit of an existing plant and repot it. Give the cutting water and sunlight, and it will quickly blossom into a full grown plant.

While catnip is a perennial plant, many gardeners find it best to repot it each year, usually using a cutting from the previous year’s plant. This helps keep the plant strong and healthy. You don’t have to do this, but it can help keep your plant healthy year to year.

Lastly, as always, go with a high quality potting soil. Look for one that is well draining and your catnip plant will thank you for it.

Lighting

Catnip likes a good amount of light, but can do well in moderate light conditions as well. Look to get at least 5+ hours of bright sunlight, or around 8 hours of indirect sunlight. These are minimums to look for though, and a bit more will only help your plant.

If you notice your plant is looking leggy, it has long, weak stems, then it is not getting enough light. This is the plant’s natural response as it tries to “reach” for more light. The solution is simply to give it more light, and potentially add support to weak stems while it regains strength.

Watering and Feeding

Catnip plants enjoy being watered frequently, but don’t like sitting in moist soil. An ideal situation is watering every few days, while also providing well draining soil so that it doesn’t sit in soggy soil. Check that the top inch or so of the soil is dry every other day and water if it is.

Catnip is fairly resistant to droughts and wilting, and can spring back quickly even if it doesn’t receive water for some time. This gives you a little bit of wiggle room, and you should look underwater rather than overwater.

For feeding, use a blanched fertilizer and look to do so every 3-4 weeks during the growing season. For those in cooler climates you can stop fertilizing in late fall into winter, and then pick up again in the spring.

Other Tips

One last thing to keep in mind is that catnip will sometimes bolt or begin to flower. If you see flowers simply snip them off before they grow too large. This will encourage more leafy growth of the plant, which leads to more harvestable catnip.
