How to Grow Purslane (Kulfa) in Pots From Seed or a Bunch
Purslane (kulfa) is so easy that farmers spend their summers pulling it out. If you want to know how to grow purslane on purpose, scatter seed on warm, damp soil or just push a stem cutting into a pot, put it in full sun, and you’ll be cutting a bowl of sour, juicy greens in about a month. The real skill is harvesting it the right way so it keeps coming.
Kulfa at a glance
- Plant: Portulaca oleracea, a fleshy summer annual that seeds itself
- Sow: March to August in the plains (by city below)
- Pot: any wide pot 8 to 10 inches across (4 to 6 litres), or a shallow grow bag
- Mix: 2 parts soil, 1 part sand, 1 part compost
- Sun: 6 hours or more; it loves heat
- Germination: roughly a week to ten days in warm soil
- First cut: about 4 to 6 weeks from seed, 2 to 3 weeks from cuttings

Is it the edible kulfa or a lookalike?
NC State extension describes purslane as a low, mat forming succulent with smooth reddish stems, fleshy paddle shaped leaves bunched at the tips, and small yellow flowers that open only in the morning. Two plants get mixed up with it.
- Spotted spurge (dhoodhi): thin, flat leaves on wiry stems, and white milky sap when snapped. Kulfa’s sap is clear. The milky one is not food.
- Ornamental moss rose (gul e dopahri): needle shaped leaves and big bright flowers. Related, but grow it for colour.
When to sow purslane, by city
| Zone | Sowing window | Note |
|---|---|---|
| Karachi, coastal | February to September | Nearly year round; slows in the short winter |
| Multan, Sukkur, Bahawalpur | March to April, again July to August | Survives 45C, but leaves turn tough without water |
| Lahore, Faisalabad, Delhi | Late March to August | Monsoon sowings grow fastest |
| Islamabad, Peshawar | April to August | Wait for warm nights |
| Hills | May to July | Short season only |
Cold kills it. Once nights drop near 10C in November, the plants fade; let the last ones drop seed and they return next spring.
Two ways to start: seed or cuttings
From seed
- Fill a wide pot with the mix and water it well.
- Mix a pinch of the dust fine black seed with a spoon of dry sand.
- Scatter it on the surface. Do not bury it; purslane seed needs light.
- Mist gently every day until sprouts show, usually within ten days in warm weather.
- Thin so plants stand about 10 to 15 cm apart.
Seed from tukhm e khurfa sold at pansari shops sometimes sprouts if it’s fresh, but packaged vegetable seed is more reliable.
From cuttings (the faster route)
- Buy a bunch of kulfa from the sabzi wala, or snip a 10 cm tip from a friend’s plant.
- Strip the lower leaves and push 3 cm of stem into moist mix.
- Keep it in bright shade for three or four days.
- Roots form within a week; move it into full sun.
This is the same trick used for mint and tulsi in our free herbs from cuttings guide, and it often beats seed by weeks.
Care: easy, but not neglect
- Water: it is drought tough, but tender leaves need regular water. In May and June, water pots daily; in the monsoon, only when the top is dry.
- Soil: anything that drains. Rich soil gives bigger, softer leaves.
- Feeding: a handful of compost per pot each month is plenty. Avoid heavy nitrogen sprays on a crop you eat raw.
- Flowers: pinch off flower buds if you want leaves; flowering plants turn tougher and set seed fast.
Cut for a bushier plant
Cut the top 8 to 10 cm of each stem, just above a pair of leaves, instead of pulling the whole plant. Two new shoots grow from each cut, and a single pot keeps producing for months.
Leaves turning yellow and other problems
| Sign | Cause | Fix |
|---|---|---|
| Yellow, soft, rotting stems | Waterlogging in the monsoon | More sand; skip watering in rain |
| Lower leaves yellow, plant flowering hard | End of life or hunger | Cut back and feed compost, or sow fresh |
| Curling leaves, sticky tips | Aphids | Hose off; neem soap spray, wash before eating |
| Holes and chewed stems | Caterpillars or snails | Hand pick in the evening |
| White patches | Mildew in still, humid weather | Space plants; remove affected stems |
When and how to harvest
Start cutting when the plant has spread to about the width of your hand, around four to six weeks from seed. Pick in the morning, when stems are crisp. Young tips are the best eating; thick old stems are stringy. Kulfa wilts quickly, so cook it the same day. For saag recipes and cooking ideas, see chaulai and kulfa saag.
Purslane contains soluble oxalates, like spinach. People with a history of kidney stones or kidney disease should ask their doctor how much leafy greens like this suit them, and everyone gets less oxalate by cooking it and draining the water. NC State extension lists it as a low severity problem for cats, dogs and horses, so keep pets from grazing it. Never forage kulfa from roadsides, drains or sprayed fields, and never eat a lookalike with milky sap.
Grow it or skip it?
Grow it anywhere hot. It is the best pot green for a sun blasted roof in Multan or Karachi, where spinach and methi give up in summer, and a top choice in our beginner kitchen garden list. Skip it only in the hills in winter. For more summer crops, browse Kitchen Garden.
Kulfa growing questions
How fast does purslane grow from seed?
You can usually start cutting in four to six weeks in warm weather. Cuttings get you there in two to three weeks.
Kulfa ke beej kaise lagaye?
Mix the tiny seed with sand, scatter it on damp soil without covering it, and mist daily. It sprouts in about a week in warm weather.
Can I grow purslane from store bought kulfa?
Yes. Stems from a fresh bunch root easily in moist soil within a week. It is the quickest way to start.
Does purslane come back every year?
It is an annual, but it drops so much seed that it usually returns by itself each spring in the same pot or bed.
Should I let purslane flower?
For eating, pinch the buds. Let one plant flower late in the season if you want free seed for next year.
Can purslane grow in partial shade?
It survives, but grows leggy with thin leaves. Six hours of direct sun gives the thick, juicy stems you want.
Is purslane a weed or a vegetable?
Both. It is a common field weed and an old summer vegetable in Pakistan, India and the Mediterranean.
How often should I water purslane in pots?
Daily in a hot spell, less in the monsoon. It survives drought but stays tender only with steady water.
Is purslane safe for dogs and cats?
It is listed as a mild problem for pets because of its oxalates. Keep pots out of reach of animals that chew plants.
