Growing The Indestructible Mint Indoors

Mint is one of the most popular herbs there is to grow. It’s in the cool, cheery taste of candy canes on Christmas trees. In the warm comfort that is mint tea. It’s even in the summery fizz of the classic mojito. It’s in everything.

Thankfully, it’s easy to grow indoors! Even with just a few store-bought sprigs and a jar of water, you can enjoy mint in a few weeks!

I meant that title, by the way. Mint is the crawling, sweet herb that is almost impossible to be killed by anyone.

I am the exception. I did kill mint plants. Twice. To find out how and avoid my mistakes when growing mint indoors, you’ll have to keep reading.

Growing Mint Indoors

A little of Mint Mythology:

Did you know that mint got its name from Greek mythology? According to the varying tales, a water nymph named Menthe caught the eyes of Hades. And Persephone was not a fan of it. So she stomped on Menthe until she turned into a fragrant crawling plant.

Ouch.

I guess the many varying tales explain the bajillion varieties of mint to choose to grow indoors. Well, there are at least 18 cultivated varieties. The most popular are Peppermint and Spearmint. But there are also other varieties like apple mint, chocolate mint, and catnip!

But that still leaves one crucial question…

Where Do You Get Mint Plants?

You can get mint plants from many different places!

Most nurseries, home improvement stores, and farms sell many varieties of mint. In the summer, it lines the shelves with other herbs like basil, thyme, and rosemary. Mint spreads like crazy, so getting only one plant will last you a lifetime.

But what about if it’s cold outside, and you can’t find it anywhere? Not a worry! Supermarkets usually sell sprigs of herbs in their produce section, which are perfect for propagating into new mint plants for your home! I don’t understand why people buy fresh herbs from grocery stores when they can grow their own.

Growing plants from seed are usually preferable, but growing from mind seeds create mint that isn’t true to seed. Even buying from very reputable nurseries doesn’t guarantee successful mint.

Requirements for Growing Mint Indoors

While mint is a plant that can withstand almost anything, it still has preferences and requirements. Mint doesn’t demand much, so doing the bare minimum can be enough to make your indoor mint flourish. I’ve made almost every mistake in this article (and have learned from other gardening mistakes), so I’m quite familiar with what mint can handle.

Sun

Mint is a plant that does best in partial sun, but it can tolerate full sun. I keep my mint on the eastern side of my house, and it flourishes just fine! Without enough sun, your mint will become spindly and sickly.

Space

Never plant mint in an uncontained area or the same pot with another plant. It will take it over before you know it. Seriously, I know someone who accidentally left some mint on their lawn, and they still can’t get rid of it to this day no matter what they do.

As I’ve said before, mint spreads like wildfire. So how deep a pot isn’t as important as how wide it is. A pot that’s at least 8 inches wide is the minimum amount of room for your mint to grow freely. Make sure it has drainage holes so it doesn’t become waterlogged. Speaking of water…

Watering

Don’t treat mint like a succulent. That is, don’t leave the soil to dry completely and then soak it. That is certified mint torture, and your mint will become wilt and dry up.

But on the other extreme, you need to drink lots of water every day. Your mint plant, however, doesn’t. Mint roots need room to breathe, so drowning them in water is as bad as not watering your mint at all.

This is the mistake that double killed my mint plants. By watering the plant so much, the roots and plants started to rot. Once the roots start rotting, it’s hard to recover the plant. Rotten mint smells as bad as it sounds. My entire room smelled like skunky mint until I threw the mint out.

So how often should you water your mint plant? The best way to find out is through your hands. Stick half of your finger (or a wooden skewer if you don’t want to ruin your nails) into the soil.

If it comes out noticibly dry, then its time to water. But don’t water so much that water seeps from the bottom of the pot. If it starts to, no biggie, mint is resilent and forgiving. Which brings us to our next section…

Soil

Every plant loves good well-draining soil, and mint is no exception. It gives the roots space to breathe and prevents waterlogging.

Store-bought container soil is okay for mint. But if your want the best for your plant, you can make your own!

Fertilizer

With growing mint indoors, a little bit of fertilizer goes a long way. Too much of it can cause the flavor to diminish. Every four to six weeks, feed it with water-soluble fertilizer or sprinkle a bit of Epsom salt.

Caring for Your Mint

The only other thing you need for growing happy mint indoors is to prune it regularly. Pruning mint regularly encourages bushier growth and keeps it from flowering. Flowering mint causes the flavor and taste to be less intense. And your mint can also become tired and become spindly, so take care of your mint!

Small tip: If your mint is getting spindly and tired, just cut everything down to nubs. It’ll feel cruel and will hurt (emotionally), but your mint plant will thank you. Your mint will be just fine and grow back strong and vigorously!
