How to Grow Cauliflower at Home (Gobi): Avoid Button Heads
Cauliflower is the fussiest of the winter cabbages, and the honest answer to how to grow cauliflower at home is: match the variety to the month. Raise seedlings in a tray from late August to October, move each one at four to six weeks old into its own 15 to 20 litre pot, keep it growing without a single check (no drying out, no hunger), and cut the white head about 60 to 70 days after transplanting, before it loosens. Get the month wrong and you’ll get a “button”, a tiny head on a small plant.
The short version
- Method: seed in a nursery tray, then transplant; cuttings and grafting aren’t used
- Nursery sowing (Punjab and Delhi plains): late August to October, by variety type
- Transplant: seedlings 4 to 6 weeks old, with 4 to 5 true leaves
- Pot: 15 to 20 litres (12 to 14 inch wide and deep), one plant each
- Sun: 6 hours
- Harvest: roughly 60 to 70 days after transplanting

Why does variety and timing matter so much?
Gobi forms its head (the curd) only within a fairly narrow comfortable temperature band, and it reacts badly to stress from heat, cold or thirst. That’s why seed packets in South Asia are sold as early, mid and late types. Early types tolerate warmer weather and go in first; late “snowball” types need the cold heart of winter. A late type sown in August sulks; an early type sown in November buttons.
| Zone | Nursery sowing | Best bet |
|---|---|---|
| Punjab plains: Lahore, Faisalabad, Delhi | Late August (early types) to October (late types) | Mid-season types sown in September are the easiest start |
| Hot dry: Multan, Bahawalpur, Sukkur | September to October | Mid types; protect from late heat in February |
| Coastal humid: Karachi | September to November | Early and mid types; the mild winter is short of cold |
| Sub-humid: Islamabad, Peshawar | August to September | Mid to late types |
| Hills | Spring to early summer | Snowball types |
Read the packet. If it says nothing about season, ask the seed shop whether it’s an early, mid or late (aghaiti, darmiyani, pichhaiti) type for your area.
How to raise strong seedlings
- Fill a seedling tray or a shallow tub with fine, moist mix: half compost, half cocopeat or sifted soil.
- Sow seeds 0.5 to 1 cm deep, 2 to 3 cm apart. Keep in bright shade until they sprout in about a week.
- Move into morning sun once up. Water with a fine rose so you don’t knock them flat.
- At 4 to 6 weeks, with 4 to 5 true leaves, transplant in the evening. Older, root-bound seedlings are a common cause of buttoning, so don’t hold them back in the tray.
- Plant each seedling slightly deeper than it sat, firm the soil around it, water well and shade it for two days.
Pot, mix and feeding: cauliflower is hungry
One plant per 15 to 20 litre pot or grow bag, or 45 cm apart in a bed. Use a rich mix: 2 parts soil, 1 part well-rotted compost, plus a handful of sand for drainage (see our potting mix ratio). Firm the soil well; loose fluffy mix lets the plant rock and stall.
Nitrogen shortage is a classic cause of button heads. Mix two handfuls of compost in at planting and add one more every three weeks. A balanced NPK at label rate three weeks after transplanting helps in pots, where nutrients wash out quickly. Pale, purple-tinged lower leaves usually mean the plant is hungry.
Watering through hot spells and frost nights
Steady moisture is the rule. In a warm October, a pot in sun may need water daily; in December and January, every 3 to 5 days. One weekend of dry soil can stunt the head for good. On frost nights in Lahore or Islamabad, water in the afternoon and drape a sheet over the plants; long cold snaps after the plant is big can push it to bolt. Karachi growers fight the opposite: give light afternoon shade if a hot spell arrives as heads form.
The leaf-tie for a white head
The moment a head the size of a coin appears, fold two or three big outer leaves over it and hold them with a rubber band or a clothes peg. Sunlight turns curds yellow and fuzzy; shade keeps them white and tight. Check under the leaves every two days. Self-blanching varieties fold their own leaves and don’t need it.
Why is my cauliflower not forming a head?
- Button heads: nitrogen shortage, an early type planted late, or old seedlings transplanted.
- No head, all leaves: too warm for that type, or still too young. Give a mid type time into December.
- Loose, grainy, “ricey” head: left too long or a hot spell; cut sooner next time.
- Yellow, purple-tinged head: sun exposure; tie leaves over it.
Pests and diseases, organic first
| Problem | Signs | First response |
|---|---|---|
| Diamondback moth and cabbage caterpillars | Holes, green droppings, small green caterpillars | Hand pick daily; fine net over young plants |
| Aphids | Grey clusters under leaves | Water jet, then a neem oil spray |
| Cutworms | New seedling cut at soil level | A paper collar round the stem at planting |
| Leaf spot or blight | Brown ringed spots | Remove spotted leaves, water the soil only |
| Yellow lower leaves | Old leaves, pale and dropping | Natural, or hunger: feed compost |
Caterpillars hide inside the head and between leaf stalks. After harvest, soak the head in salted water; our gobi cleaning guide shows how.
When do you cut the head?
Cut when the head is full, white and tightly packed, before the curds start to separate into little branches. In pots that may be 10 to 15 cm across, smaller than market gobi, and that’s fine. Cut with a sharp knife and leave a ring of leaves around it; it keeps better. Don’t wait for “a bit bigger” once it starts to loosen.
Grow it or skip it?
Maybe. Grow it if you enjoy a challenge and can water daily; a fresh, tight home gobi is a proud thing. Skip it as a first crop: palak, methi, mooli and beetroot forgive much more. One plant per 20 litre pot also means a balcony gives only a few heads, so the ground suits it better. Easier starters are in our first five plants guide and the Kitchen Garden hub.
Caterpillars tempt people into strong pesticides on a leafy crop eaten within days. Start with hand picking and nets. If you ever use a chemical, read the full label, wear gloves and a mask, keep children and pets away, and wait the stated days before cutting. Keep fertiliser bags and sprays locked away from children. Wash the head well before cooking, and keep pots off parapet edges.
Cauliflower growing questions
Can cauliflower be grown in pots?
Yes, one plant per 15 to 20 litre pot with rich mix and steady watering. Heads are often smaller than market ones.
What is the best time to plant cauliflower in Pakistan?
Sow the nursery from late August to October in the Punjab plains depending on variety type, then transplant 4 to 6 weeks later.
Why is my cauliflower head so small?
That’s buttoning: usually nitrogen shortage, an early variety sown late, old seedlings or a dry spell.
How long does cauliflower take to grow?
About 60 to 70 days from transplanting for many varieties, plus 4 to 6 weeks in the nursery.
Why are my cauliflower leaves turning yellow?
Old lower leaves yellow naturally. Widespread yellowing usually means hunger or waterlogging.
Why did my cauliflower turn yellow and fuzzy?
Sunlight on the head, or left too long. Tie leaves over young heads and cut on time.
Can I grow cauliflower from a cutting of the stem?
Not in practice. Grow it from seed.
Do I need to tie cauliflower leaves?
For most varieties, yes, once a coin-sized head shows. Self-blanching types don’t need it.
Can cauliflower grow in summer?
Not in the plains. Heat stops heads forming. Hills grow it in summer.
