How to Grow Gotu Kola (Brahmi Booti) and Spot the Lookalikes
Most people asking how to grow gotu kola have already killed one pot by letting it dry out. This creeping herb is a pond edge plant: give it a shallow, wide pot, damp soil all the time, and bright shade instead of hard sun, and it will run over the rim within a season. The bigger trap comes first, though. Half the plants sold as “brahmi” in nurseries are a different herb entirely.
Quick facts
- Plant: Centella asiatica (gotu kola, mandukaparni, often sold as brahmi booti), a low creeping perennial
- Plant out: February to April or July to September in the plains
- Pot: shallow and wide, 10 to 12 inches across and 6 inches deep (about 5 to 8 litres), or a tray
- Mix: 2 parts soil, 1 part compost, 1 part cocopeat, kept moist
- Light: 3 to 4 hours of morning sun, then bright shade
- Propagate: rooted runners; seed is slow and unreliable
- First harvest: about 6 to 8 weeks after a runner settles

How to identify gotu kola (and what gets sold in its place)
Learn the leaf before you buy. North Carolina State extension describes it as a stolon spreading plant with smooth, fan shaped to nearly round leaves, toothed at the edge, each on a stalk often longer than the leaf. Flowers are tiny, white to pink, hidden near the soil.
| Plant | Leaf | Flower and feel |
|---|---|---|
| Gotu kola (Centella) | Round to kidney shaped, scalloped edge, long stalk | Tiny pink or white, hidden; mild green, slightly bitter smell |
| Bacopa (jal brahmi) | Small, oval, thick and succulent, stalkless, paired along the stem | Pale white to lilac bells, easy to see |
| Dollarweed (Hydrocotyle) | Round like a coin, stalk joins the middle of the leaf | Small white clusters on taller stalks |
| Dichondra | Smaller kidney shaped leaves, smooth edge, soft hairs | Minute greenish flowers |
The naming muddle is a whole story of its own; our gotu kola and brahmi confusion post untangles it, and brahmi booti (bacopa) covers the other plant.
The stalk test at the nursery
Turn a leaf over. If the stalk joins the leaf at a notch on its edge, like a kidney bean, it is probably gotu kola. If it joins in the dead centre like an umbrella, it is a Hydrocotyle pennywort. If there is no stalk at all and the leaves are thick and paired, it is bacopa.
Propagation that works: runners, not seed
Gotu kola spreads by runners that root wherever a node touches damp soil. One healthy clump can fill several pots by autumn.
- Find a runner with two or three nodes and small white roots under them.
- Cut it free with a clean blade, keeping the roots.
- Lay it flat on moist mix and press each node into the surface; pin with a bent wire if needed.
- Keep it in shade and constantly damp for two weeks.
- New leaves mean it has taken; then give morning sun.
Rooting is high in warm, humid months and slow in winter. Seed is tiny, patchy to germinate and rarely sold true to name, so skip it. The same pinning trick works for mint; see propagate herbs from cuttings.
Where gotu kola grows best in Pakistan and North India
| Zone | How it does | Main tip |
|---|---|---|
| Karachi, coastal | Easy all year | Shade at midday; rinse salt build up monthly |
| Lahore, Faisalabad, Delhi | Good spring and monsoon; sulks in June and January | Move to shade from May; shelter from frost |
| Multan, Sukkur, Bahawalpur | Hard in summer | North facing spot, tray of water under the pot |
| Islamabad, Peshawar | Good from March to October | Indoors or veranda on frost nights |
| Hills | Summer only | Bring a pot indoors for winter |
Care: water, light and food
- Summer water: stand the pot in a tray with 1 to 2 cm of water from April to September, so the mix wicks moisture up. Change the tray water every two or three days so mosquitoes cannot breed.
- Winter water: remove the tray; keep the soil moist, not swampy. Frost blackens leaves, but the runners usually regrow in spring.
- Light: leaves turn yellow and crisp in full afternoon sun. Morning light gives the thickest mat.
- Feeding: a thin layer of compost on top every six weeks in the growing season. Strong chemical fertilisers burn the shallow roots.
- Repotting: divide every spring or the centre thins out.
Common problems
- Brown edges: dry soil or hot sun; move and water more.
- Rotting in winter: waterlogged and cold; drain the tray, let it breathe.
- Holes in leaves: snails and slugs at night; pick them off by torchlight, or circle the pot with dry ash.
- Aphids under new leaves: wash off; neem soap spray if they return.
When to harvest gotu kola
Start picking once the mat covers most of the pot. Cut leaves with their stalks, taking no more than a third at once, and the plant refills in two to three weeks. Morning picking gives the freshest leaves. Wash well, since this plant grows low and splashes with soil.
In Sri Lanka, Kerala and Southeast Asia, the leaves are traditionally eaten as a shredded salad (gotu kola sambol) or in drinks. Any health uses belong to tradition, and the linked posts carry the cautions.
Never pick gotu kola from drains, roadside ditches or polluted ponds: the plant takes up heavy metals from contaminated soil. Pregnant or breastfeeding women, people with liver disease, and anyone taking regular medicines should talk to their doctor before using it beyond an occasional salad leaf. Stop and get medical advice for skin rash, yellowing of eyes or stomach pain after eating it. NC State lists it as potentially poisonous, so keep pots away from grazing pets.
Grow it or skip it?
Grow it if you have a shady balcony, a damp corner or a bathroom window ledge in the warmer months. It is one of the few herbs that prefers the shade most flats have. Skip it if you can only offer a hot, west facing roof in Multan. More herbs and food plants are in Kitchen Garden, and the right soil blend is in our potting mix guide.
Gotu kola growing questions
Is gotu kola the same as brahmi?
Not botanically. In parts of India gotu kola is called brahmi, but the brahmi of Ayurvedic texts is usually bacopa, a different plant with small, thick, stalkless leaves.
How do I grow gotu kola from a cutting?
Use a runner piece with rooted nodes, pin it on damp mix in shade, and keep it wet for two weeks. New leaves mean success.
Can gotu kola grow indoors?
Yes, on a bright windowsill with some direct morning sun. Without enough light it gets leggy, with long stalks and small leaves.
Why is my gotu kola dying in summer?
Usually heat plus dry soil. Move it to shade and stand the pot in a shallow water tray through the hot months.
Can I grow gotu kola from seed?
It is possible but slow and patchy, and seed is rarely labelled reliably. Runners are far easier.
Does gotu kola need full sun?
No. In the plains, morning sun with afternoon shade gives the best leaves; full sun in May and June scorches it.
Where can I find gotu kola plants in Pakistan?
Some nurseries carry it under brahmi, mandukaparni or pennywort; check the leaf shape and stalk before paying.
Is gotu kola invasive?
In damp ground it spreads quickly by runners. Grow it in a pot unless you want it everywhere.
How often can I harvest gotu kola?
Every two to three weeks in the growing season, taking up to a third of the leaves each time.
