Things you need to grow mint indoors

If you want to grow healthy mint indoors, you must provide your herb with the following.

1. Water

Learning how to grow mint indoors also requires your knowledge about their water needs.

Fortunately, mint is one of those herbs that are not too demanding and sensitive regarding water. You can overwater or underwater it and still thrive. However, giving your mint indoors a balanced water supply would be better.

That means you just need to water them if the soil feels and looks dry. Make sure that the soil is always moist but never too wet. You can water it every other day rather than once a week. 

Likewise, keep the potting mix slightly acidic. Add peat moss or composted cow manure to help balance the pH levels.

2. Sunlight

Make sure your mint has at least six hours of sunlight daily. If you don’t have direct sunlight in the room where your mint is growing, get an artificial light bulb that gives off full-spectrum light like those used for houseplants. 

You can also try putting your mint near a window where there’s direct sunlight coming through. Just make sure that it doesn’t get too hot!

Growing mint in the soil is one of the widely used ways. Here’s how to do it.

  • You can use plastics and decorative pots but avoid using clay pots.

2. How to grow mint indoors in water?

You can also grow mint indoors using water. This method does not need potting soil, which means less mess, no watering needed, and your mint will never get fungus gnats. But you need to know that mint won’t live forever in water. That means this method is only applicable if you want an occasional harvest.

  • Do not use nutrient solutions. Instead, use a balanced formula.

Pests of mint indoors to watch out for

Mint is a great addition to the garden but can also be grown indoors. If you’re interested in doing so, keep in mind that pests can affect your mint plants.

Spider mites

These tiny bugs are hard to see and can quickly destroy your mint plants because they suck out their sap. Spider mites are also difficult to get rid of. They can survive even when no food or water is available.


This little bug sucks out the sap from your mint plant and leaves behind honeydew, which attracts ants and other insects that feed on it. You’ll know if you have whiteflies because they leave behind a sticky residue on your plants’ leaves, stems, and flowers.


The best way to prevent these pests from infesting your mint plants is to keep them healthy by watering regularly and fertilizing once every two weeks with compost tea or liquid seaweed fertilizer (10-15-30). Make sure that you don’t overwater or underwater your plant and try not to overcrowd them!
