The Benefits of Growing Mint Indoors

If you want to learn how to grow mint, you’ll be pleased to know that it’s very easy. Aside from the fact that you need very little space to grow mint at home, opting for this particular herb has other benefits, too.

Mint Plant Benefits

  • Growing mint indoors means the plant is less exposed to pests, so there is no need for insecticides or harsh chemicals to protect your crop
  • Mint is notoriously easy to grow – so it’s great for novice gardeners who want to try growing their own produce
  • Mint requires little aftercare
  • Mint is known for its hardiness (meaning it’s hard to kill!)
  • Growing mint indoors means you have easy access to the herb when using it for cooking

In short, mint is a great entry level herb to start growing indoors, and is a lower-cost gardening method than say, aquaponics, which is also great for small spaces, but a bit pricier to put together (if you are wondering how to grow mint indoors in water, however, aquaponics is the way to go).

Mint is hardy, it’s easy to grow, and it’s great for keeping in your kitchen! 

Plus, as an added bonus, there are other mint plant uses besides cooking; for example you can use mint leaves for skin conditions such as acne!

Potential Issues With Growing Mint

Of course, you can also try growing mint outdoors if you have access to a garden (and a relatively stable climate required for growing mint).

But this can carry its own problems.

Mint is a very aggressive plant, so when left to grow outdoors it has a tendency to take over and spread like a weed.

This means that it has to be kept under control, and requires due care and attention. But while it is a hardy herb, it isn’t without its vulnerabilities.

It can be susceptible to diseases such as mint rust, anthracnose and verticillium wilt.

There are also pests that mint can be vulnerable to (such as aphids, spider mites and mint root borers), but growing the plant indoors helps to minimise this risk.

Side note: If you’ve chosen mint because it’s hardy and easy to grow, you may also be interested growing flowering plants such as the cosmos flower – a great addition to any garden. 

What You’ll Need to Grow Mint Indoors

What You Need

  • Mint seedlings
  • Potting soil
  • Rich compost
  • Containers with drainage holes (as large as your space will allow)
  • Trays to place your containers on (baking trays work well)
  • Fertilizer (optional)
  • Windowsill space to grow your mint

When choosing a space to grow your containers of mint, try to select a windowsill that gets several hours of indirect sunlight throughout the day. A south facing location works well!

How to Grow Mint In a Pot

Growing and harvesting mint at home couldn’t be simpler. As long as you have some mint seedlings, soil, and the correct containers – you’re good to go!

Different types of mint plants grow differently. Spearmint grows upright; while peppermint tends to spread outward, so keep this in mind when deciding which type you will grow.

Step #1. Plan Your Space

Before you even begin to plant your mint containers, it’s worth taking a look at the space you’re working with.

Ideally, you will need to place your containers somewhere that gets adequate sunlight, with room for drainage trays (you don’t want water leaking all over the windowsill).

Step #2. Select Your Containers

When it comes to growing mint, you need to give the plant adequate space to grow.

Opt for rectangular containers so that you can fit them easily on the windowsill, and make sure there are drainage holes in the bottom.

Place them on trays so that the windowsill surface is protected (and remember to tip excess water away regularly).

Step #3. Choose Your Mint Seedlings

There are plenty of mint varieties to choose from.

Spearmint is a popular choice, but you can also opt for pineapple mint, chocolate mint, apple mint or peppermint.

Note, however, that it is very difficult to grow peppermint from seeds – so you’ll need to use cuttings if you opt for this variety.

Check out the mint plants for sale at your local gardening store, and see which you prefer.

Step #4. Prepare Your Planters

Fill each of your planters with potting soil or rich compost. It is recommended to use potting soil here, as the soil is often pasteurised to protect against pests and fungi.

Step #5. Plant Your Mint

Make indentations in the soil and place your mint seedlings inside. Make sure you don’t overcrowd the containers. Pack the soil around the seedling so the mint stands up on its own.

Step #6. Water and Fertilize

Water the mint seedling and use fertilizer if you wish. You can use fertilizer sticks or liquid fertilizer as per the packet instructions. Just note that too much fertilizer can affect the flavour of the mint.

How to Care for Mint Plants 

You might be wondering how often to water mint – but it’s actually an intuitive process.

Place the containers in your selected indoor space and water whenever the soil looks dry.

Mint needs to be kept moist, but not sodden – so test the soil with your finger before watering. You can also rotate your containers every couple of days to ensure your plants are soaking up sunlight on all sides. 

If you’re wondering how to harvest mint – it’s very easy! 

Mint takes about 90 days to reach full maturity, but you can keep pinching off leaves as the plant matures.

Or, you can harvest the entire plant, leaving a couple of inches for regrowth. It’s up to you. (If you want to preserve your own home grown produce, why not start here by checking this article on how to store fresh basil!)

While the above will work just fine, it should be noted that there are other methods for growing mint indoors. For example, you don’t need to grow mint from seedlings.

Some people grow mint from cuttings. They simply take a cutting of mint from an established plant, and pop it in a container of water.

When placed in sunlight, the cutting will start to grow new roots and can then be planted in soil.
