How to Grow Mint at Home: The Easiest Herb for Beginners

If you have never grown anything before, start with mint. It is fast, forgiving, and so eager to grow that the main challenge is stopping it from spreading. Get a pot with drainage, a bright-ish spot, and a rough watering rhythm, and you will have fresh mint for months.

Mint asks for very little: its own pot, a bit of light, and steady water.

Why mint is the perfect first plant

  • It roots itself. Drop a cutting in a glass of water and it grows roots on its own. No seeds, no special gear.
  • It is hard to kill. Mint shrugs off missed waterings and less-than-perfect light better than almost any herb.
  • It grows fast. Within a few weeks a single stem becomes a full, bushy pot.
  • You will actually use it. Tea, chutney, lemonade, salads, garnishes. The more you pick, the more it grows.

The easiest way to start: a cutting in water

You do not need seeds. If you can get one healthy sprig of mint, from a grocery bunch, a friend’s plant, or a nursery, you can grow a whole plant.

  1. Snip a stem about 10 cm long, cutting just below a point where leaves join the stem.
  2. Pull off the lower leaves so the bottom half of the stem is bare.
  3. Stand it in a glass of water on a bright windowsill, keeping the leaves above the waterline.
  4. Change the water every 2 to 3 days so it stays fresh.
  5. In about a week you will see white roots. Once they are a couple of centimetres long, plant the cutting in a pot.
Tip: Start two or three cuttings at once. They root so easily that you will have spare plants to pot up or give away.

Growing mint from seed

Seeds work too, they are just slower. Scatter a few on moist potting soil, cover with a thin dusting of soil, keep it lightly damp, and expect sprouts in 10 to 15 days. Thin to the strongest seedlings so they have room. Most beginners find cuttings faster and more reliable, so use seeds only if that is what you have.

The one rule that saves your other plants: its own pot

Mint spreads through underground runners and will happily choke out anything sharing its container. Always give mint its own pot. A pot 15 to 20 cm wide with a drainage hole is plenty. This single habit prevents the most common mint complaint: “it took over everything.”

Light and watering

Mint is refreshingly relaxed about light. 3 to 5 hours of sun a day keeps it full and flavourful, but it tolerates partial shade better than basil or tomatoes, so a less-sunny windowsill is fine.

Watering is where beginners slip. Mint likes soil that stays lightly moist, but not soggy. Use the finger test:

  • Push a finger about 3 cm into the soil.
  • Damp? Wait.
  • Dry? Water at the base until a little drains from the bottom.
Watch out: A small pot on a hot, windy day can dry out fast. In a heatwave, check mint daily and water in the cool of the morning.

Pinch it to keep it bushy

The trick to a full plant instead of a few long, floppy stems is the same as basil: pinch the top. When a stem has several sets of leaves, pinch out the very top just above a leaf pair. The plant responds by branching sideways, giving you twice the leaves. Harvest from the top little and often, and it will thank you with more growth.

Common mint problems (and quick fixes)

  • Long, thin, floppy stems → not enough light or not enough pinching. Move it brighter and start pinching the tops.
  • Yellowing lower leaves → usually soggy soil. Let it dry out more between waterings and check the drainage hole. Our guide on why leaves turn yellow walks through every cause.
  • Pale orange spots under the leaves → mint rust. Remove affected leaves, improve airflow, and avoid wetting the foliage.
  • Woody, sparse growth after a few months → give it a hard trim down to a few centimetres and it will flush back fresh.

Growing mint indoors

Mint is one of the best herbs for an indoor windowsill. Give it your brightest spot, keep it away from cold drafts and radiators, and never let the pot sit in a saucer of water. Indoors it dries out more slowly, so lean on the finger test rather than a fixed schedule.

Once your mint is established, the same habits that keep basil bushy and healthy apply here: good light, careful watering, and regular pinching. New to all of this? Start with our complete beginner’s guide to growing food at home.

Frequently asked questions

How long does mint take to grow?

A cutting in water grows roots in about a week. Once potted, you can start picking leaves in around 3 to 4 weeks, and it keeps producing for months.

Can I grow mint from a cutting?

Yes, and it is the easiest way. Snip a 10 cm stem, remove the lower leaves, and stand it in a glass of water on a windowsill. Roots appear in about a week, then move it to a pot.

How much sun does mint need?

Mint is happy with 3 to 5 hours of sun a day and tolerates partial shade better than most herbs, which makes it great for less-sunny windows and balconies.

Why is my mint taking over everything?

Mint spreads by underground runners and will crowd out anything sharing its pot. Always grow it in its own container to keep it in check.

Why is my mint dying?

The usual causes are soggy soil from overwatering, or bone-dry soil in a small pot on a hot day. Use a pot with a drainage hole and water when the top few centimetres feel dry.
