How to Grow Pudina (Mint) in a Pot: Cuttings, Heat, Yellow Leaves
Buy one bunch of pudina, keep six of the thickest stems, and you have a mint pot for years. That’s the whole secret of how to grow mint plant at home in a pot: root market stems in water, plant them in a wide, shallow pot, give them morning sun and afternoon shade in summer, and cut the plant back hard whenever it gets tall and thin. Below is the full method, plus what yellow, black, leggy or flowering mint is trying to tell you.
Before you start
- Start from: fresh market stems, not seeds.
- Rooting time: about 7 to 14 days in water.
- Pot: wide rather than deep, at least 30 cm across and 15 to 20 cm deep, with a drainage hole.
- Sun: 4 to 6 hours of morning sun; shade after midday once days pass about 38°C.
- Water: when the top 2 cm of soil feels dry, which in May and June can mean every day.
- First harvest: roughly 4 to 6 weeks after planting.

How to grow mint plant from stem (the market-bunch method)
Mint grows new roots from its nodes, the little joints where pairs of leaves come out of the stem. Seeds are slow and fussy, and most mint seed doesn’t grow true to the parent, so nearly everyone in Pakistan and India starts from a kitchen bunch.
Pick a fresh bunch with firm, green stems and no black slime at the cut ends; thick stems root fastest.
- Choose 6 to 8 healthy stems, each about 10 to 15 cm long.
- Snip each one just below a node with clean scissors.
- Strip the leaves from the bottom 5 cm, so no leaf sits under water and rots.
- Stand the stems in a glass or bottle with 5 to 6 cm of plain tap water, on a bright windowsill out of harsh direct sun.
- Change the water every 2 days. It stays fresh, and it stops mosquitoes breeding in it.
- White roots appear in about a week. Plant when they’re 3 to 5 cm long, usually by day 10 to 14.
- Plant 4 to 6 rooted stems in one pot, 2 to 3 cm deep, firm the soil around them and water until it drains out of the bottom.
- Keep the new pot in bright shade for 4 to 5 days, then move it into morning sun.
Bottle or pot?
“How to grow pudina plant at home in a bottle” is a popular search. Mint lives in water for a few weeks, but plain water has almost no food in it, so the leaves turn small and pale. Treat the bottle as a nursery and move the plants into soil once the roots are long.
Pot, soil and sun: getting the basics right
Why width matters more than depth
Mint spreads sideways by runners, which are stems that creep along or just under the surface and root as they go. In a wide pot the runners fill the space and you get a thick carpet of leaves. In a tall, narrow pot they hit the wall, circle round, and the plant crowds itself out within a season. A 30 to 40 cm wide pot, or a rectangular window box, suits mint far better than a deep bucket.
Pot or ground? A pot, for most homes: in an open bed mint runs everywhere and swamps its neighbours.
A simple mix
Use 2 parts garden soil or ready potting mix to 1 part compost, with a handful of coarse sand if your soil is heavy clay. It should hold moisture but never stay muddy. Mint hates standing water more than it hates dry weather.
Mint plant care in summer
Mint is a cool-season herb by nature. In Lahore, Karachi, Delhi or Multan, a pot on a bare roof in June is simply too hot, and the leaves scorch and crisp within days. Give it morning sun, which it loves, and bright shade from about noon once the thermometer passes 38°C. Standing the pot on a brick rather than hot concrete, or under a cheap green shade net, keeps the roots cooler.
In winter, after frost in colder parts of Punjab, the top may brown off. Give it full sun, water less, and new shoots come up in February.
Watering and feeding without drowning it
Check with a finger, not a timetable. If the top 2 cm is dry, water deeply until it runs out of the drainage hole, then empty the saucer. In summer that may be every morning; in winter, every 4 to 5 days. A plant that wilts at 3 pm and perks up by evening is just coping with heat; one still limp in cool morning air needs water, or its roots are rotting.
Mint is a leaf crop, so what it needs most is nitrogen, the nutrient that builds green leaves. It doesn’t need much. A handful of compost or vermicompost scratched into the top of the pot every 4 to 6 weeks in the growing season is plenty. From the kitchen, rinsed used chai patti (no milk, no sugar) dug lightly into the soil is a fair, gentle choice, and cooled plain water from washing rice is harmless. Banana peel mostly offers potassium, which helps flowers and fruit more than leaves, so it isn’t the best match for mint. You’ll find more scrap-by-plant ideas in our Zero-Waste Kitchen section.
Why is my mint plant turning yellow, black or leggy?
Most mint problems come down to water, light and an overcrowded pot.
| What you see | Likely reason | What to do |
|---|---|---|
| Lower leaves turning yellow | Soggy soil, or a hungry, root-bound pot | Let the top dry, check the hole, add compost or repot |
| Whole plant yellow and limp | Waterlogged roots | Stop watering, tip out the saucer, repot if it smells sour |
| Stems black at the base | Root or stem rot | Cut away black parts, re-root healthy tips in water |
| Brown, crispy edges | Afternoon sun or dry spells | Afternoon shade, more regular watering |
| Orange dots under leaves | Mint rust (a fungus) | Remove affected stems, bin them, don’t compost |
| Tall, thin, few leaves | Too little light, never pinched | More sun, cut back by half |
Why is my mint plant so leggy?
Mint stretches towards light. Indoors, or behind a grille in deep shade, it grows long stems with wide gaps between the leaves. Move it to brighter light and cut every stem back to about 5 cm; within two or three weeks new, bushy shoots come up from the base.
Why is my mint plant flowering?
Long, hot days and a crowded pot push mint to flower. Small spikes of lilac or white flowers appear at the tips, and leaf growth slows while the plant puts its energy into seed. Pinch the flower spikes off as soon as you see them, or cut the whole plant back hard, and it goes back to making leaves.
Why is my mint plant covered in flies?
Tiny black flies over the soil are fungus gnats, which breed in wet soil; let the top dry out between waterings. Tiny white flies that burst off the undersides of the leaves are whitefly; wash the leaves under a strong spray of water every few days.
Cutting back, repotting and harvesting so it keeps coming
Mint grows back faster the more you cut it. Always snip just above a pair of leaves, because two new shoots grow from that node and the plant gets bushier. Take the top third of the stems at a time, never everything, and let the pot recover for a week or two.
Every two months or so in the growing season, give it a proper haircut: cut all stems down to 5 cm above the soil, water, and add a little compost. It looks bare for a fortnight and then comes back thicker. Do the same after flowering.
Once a year, ideally in February or March, or in September after the worst heat, tip the plant out. You’ll find a solid mat of roots, often dead in the middle. Cut the root ball into three or four pieces with a knife, replant the healthiest piece in fresh mix, and give the rest away. That yearly split is why a pot of mint can last a decade.
Once you have more leaves than you can use, our pudina kitchen guide covers drying, chutney and storage. If you’re unsure which mint you’re growing, peppermint vs spearmint explains the difference in smell and use.
Myth: mint needs lots of water and full sun all day
Both halves are half true. Mint does like steady moisture, but it drowns quickly in a pot without drainage, and more mint pots die from soggy soil than from a missed watering. And in cooler countries mint happily takes sun all day; in a South Asian May it can’t.
Did you know? Mint stems are square when you roll them between your fingers, a family trait it shares with tulsi and other herbs of the mint family. And peppermint is a natural cross between water mint and spearmint, which is why it rarely makes good seed of its own.
Cuttings in glasses of water and saucers under pots are perfect mosquito nurseries, including the mosquito that spreads dengue, so change the water every 2 days and empty saucers after watering. See dengue symptoms and prevention for the full breeding-site list. Pets: a cat or dog nibbling a few mint leaves is not usually a worry, though a large amount can upset their stomach. Peppermint oil and other concentrated mint oils are a different matter: they’re harmful to cats and dogs, so never put them on a pet, its bedding or in a diffuser near it. Wash leaves under running water before eating, and never spray insect killers on a plant you’re picking for chutney. If anyone gets sprayed chemicals in the eyes or swallows them, call a doctor or poison helpline straight away.
Mint plant questions people ask
How to grow mint plant at home in a pot fastest?
Root thick market stems in water, then plant 4 to 6 rooted stems together in one wide pot. A crowded start fills the pot in weeks, where a single stem takes months. Morning sun, steady moisture and a light feed of compost keep it growing quickly.
How long does mint take to root in water?
Usually 7 to 14 days in warm weather, and closer to three weeks in cold months.
Why is my mint plant dying in summer?
Usually heat and afternoon sun, sometimes combined with a pot that dries out by noon. Move it to morning sun and midday shade, water every morning if the top 2 cm is dry, and stand the pot off hot concrete. Cut it back and it often recovers once nights cool down.
Why is my mint plant turning yellow?
Most often the soil stays too wet or the pot has become full of roots and run out of food. Check the drainage hole, let the top dry between waterings, and add compost. If the pot hasn’t been split for a year, divide and repot it.
Can I grow mint from seeds?
You can, but it’s slow, and many mints don’t grow true from seed. Market stems give you the exact flavour you bought in about two weeks.
Does mint plant need fertilizer?
Only a little. A handful of compost every 4 to 6 weeks in spring, summer and autumn is enough. Heavy feeding makes soft growth with a weaker smell.
Is mint safe for cats and dogs?
A few leaves are generally not a problem, though eating a lot can cause vomiting or loose stools. Concentrated mint and peppermint oils are the real danger for pets. Keep bottles of oil well away and never use them on animals.
Can mint grow indoors?
It can survive on a very bright windowsill, but it tends to go leggy and pale indoors. A balcony or window ledge with 4 hours of morning sun gives far better leaves. Rotate an indoor pot weekly so it doesn’t lean.
