How to Grow Garlic (Lehsun) in Pots: Green Leaves and Bulbs
Wondering how to grow garlic at home? Push single cloves into a pot, pointy end up, in October or November, and you get two crops from one planting: green garlic leaves in about a month and full bulbs by March or April. Garlic (Lehsun) is slow but almost effortless. Below: the pot, the right cloves, the sowing steps, and the one moment when you must stop watering.
Quick facts
- Pot size: 10 to 15 litres, about 12 inches wide and at least 8 inches deep, for 6 to 8 cloves
- Sun: 6 hours or more for bulbs; 4 hours is enough for leaves
- Sowing months (plains): October and November
- First harvest: green leaves in 4 to 6 weeks; bulbs in 5 to 6 months
- Biggest mistake: watering right up to harvest, which rots the bulb skins

Can you really grow garlic in pots?
Yes, and it suits pots better than most vegetables. The roots are shallow, the plant stands upright and takes little room, and winter on a Lahore or Delhi balcony is exactly the cool spell it wants.
Be honest about the size of the reward, though. One clove becomes one bulb. A 12 inch pot gives you six to eight bulbs after five months, which is a few weeks of cooking, not a year’s supply. The leaves are the real bonus: mild, garlicky greens you can snip all winter while the bulbs form underneath.
Did you know? A garlic bulb only splits into separate cloves after it has felt a few weeks of cold. That’s why October planting works in the plains and a March planting usually gives one small, round, undivided bulb.
Which cloves should you plant, desi or Chinese?
Plant desi garlic if you can find it. The small, tight, purple or off-white local bulbs are already used to our short winter, and they sprout readily. The big, very white imported bulbs are bred for longer, colder seasons and often sulk here. Telling the two apart at the stall is covered in our guide to desi and Chinese garlic.
Choose the fattest outer cloves from a firm bulb. Thin inner cloves grow thin plants. Break the bulb apart only on planting day, and leave the papery skin on each clove.
The stall trick: look for a green tip
Shop garlic is sometimes treated or stored so that it won’t sprout, and such cloves can sit in soil for weeks doing nothing. So pick cloves that are already trying to grow: a green point showing at the tip, or a pale shoot visible when you peel back one skin. No sprouting bulb at hand? Keep a bulb in the fridge door for two to three weeks first. The chill wakes it up.
How to plant garlic from a clove, step by step
- Pick the pot. At least 8 inches (20 cm) deep with drainage holes. A 12 inch wide pot or a 15 litre grow bag holds 6 to 8 cloves.
- Fill with a loose mix. Roughly 2 parts garden soil, 1 part compost and 1 part coarse sand or cocopeat; the full recipe is in our potting mix guide. Stop 1 inch below the rim.
- Mark the spots. Space cloves about 4 inches (10 cm) apart and 2 inches in from the pot wall.
- Plant pointy end up. Push each clove in, flat root end down, until the tip sits about 1 inch (2.5 cm) under the surface. An upside down clove still grows, but slowly and crooked.
- Water once, well. Soak until water runs from the holes, then leave the pot in full sun.
- Wait 7 to 14 days. Green spears appear. Water only when the top inch of soil feels dry.
Green garlic in weeks, bulbs in months: which do you want?
You can have both from the same pot if you’re gentle.
For leaves: once the spears are 8 to 10 inches tall, usually 4 to 6 weeks after planting, snip one or two outer leaves from each plant with scissors. Take no more than a third. Chop them into omelettes, raita, daal tarka or paratha dough, exactly as you’d use spring onion greens. They taste of garlic without the bite.
For bulbs: every leaf feeds the bulb, so heavy cutting means smaller garlic. The simple fix is to plant two pots. Crowd one with cloves 2 inches apart and cut it freely for greens; space the other properly and barely touch it.
Watering, feeding and when to stop watering
Garlic likes steady, light moisture and hates wet feet. In a plains winter that usually means watering every 3 to 5 days; our watering guide for pots explains the finger test. Scratch a handful of compost into the surface once in December and once in late January. That’s all the feeding it needs.
From late February the lower leaves start to yellow. This is the signal, not a problem. When about a third of the leaves have turned, stop watering completely and let the pot dry for 10 to 14 days.
| What you see | Likely cause | What to do |
|---|---|---|
| No shoots after 3 weeks | Sleeping or treated cloves | Replant with cloves showing a green tip |
| Yellow tips in December | Soggy soil or no drainage | Water less, check the holes are open |
| Thin, floppy leaves | Too little sun | Move to the sunniest spot you have |
| One round bulb, no cloves | Planted late, not enough cold | Eat it; plant in October next time |
| Soft, mouldy bulb at harvest | Watered too close to harvest | Stop water when leaves yellow |
When to harvest garlic and how to dry it
In the plains, bulbs are ready in March or April, once roughly half the leaves have yellowed and the stems begin to flop. Don’t wait for every leaf to die: by then the outer skins have split and the bulb stores badly.
- Loosen first. Tip the dry pot on its side and crumble the soil away. Pulling by the stem snaps it.
- Brush, don’t wash. Rub off loose soil with your hands. Water at this stage invites mould.
- Dry in airy shade. Lay the plants in one layer, leaves still on, somewhere breezy and out of direct summer sun for 2 to 3 weeks.
- Trim and store. When the necks are papery and the leaves rustle, cut the stems 1 inch above the bulb and trim the roots. Keep the bulbs in a basket or mesh bag, never in a sealed box.
Hold back your two best bulbs for October. Garlic grown in your own pots for a few seasons settles into your balcony’s conditions.
Hills and coast: in Murree, Abbottabad or Shimla, plant in September or early October and harvest in May or June. In Karachi or Mumbai the winter is mild, so expect smaller bulbs and treat the greens as the main crop.
Garlic and its leaves are harmful to cats and dogs, so keep pots and trimmings away from pets that chew plants; other risky balcony plants are listed in our guide to poisonous plants around kids and pets. Never keep chopped garlic or garlic greens under oil at room temperature, because that can grow botulism bacteria; refrigerate and use within a few days. A wet 15 litre pot is heavy, so stand rooftop pots near walls or over beams, not in the middle of an old slab, and never balance one on a railing. Empty saucers after watering, as standing water breeds dengue mosquitoes. Throw away any bulb that is soft, mouldy or smells sour.
Growing garlic at home: common questions
How do you grow garlic from a clove?
Plant a single unpeeled clove pointy end up, about 1 inch deep, in loose soil in October or November. Water once, keep it in sun, and shoots appear in one to two weeks. Each clove grows into one whole bulb.
Can you grow garlic in pots?
Yes. Any pot at least 8 inches deep with drainage holes works. A 12 inch pot holds 6 to 8 cloves spaced about 4 inches apart.
How long does garlic take to grow?
Leaves are ready to snip in 4 to 6 weeks. Bulbs need 5 to 6 months, so an October planting in the plains is lifted in March or April.
Which month is best to plant garlic in Pakistan and India?
October to mid November in the plains. Hill areas plant a month earlier, in September or early October. Planting after December usually gives small bulbs that don’t divide into cloves.
When is garlic ready to harvest?
When about half the leaves have yellowed and the stems start to lean over. Check one bulb with your fingers first: it should feel full, with clear clove bumps under the skin.
What can I do with green garlic leaves?
Use them like spring onion greens. They’re good raw in raita and chutney, stirred into omelettes and fried rice, or kneaded into paratha dough. The flavour is milder than a clove.
Can I plant garlic from the kitchen basket?
Usually yes, if the cloves are firm. Local desi garlic sprouts most reliably. Cloves already showing a green tip are the safest choice, since some shop garlic is slow to wake.
Should I peel garlic before planting?
No. Leave the papery skin on each clove. It protects the clove from rot while the roots form.
Why are my garlic leaves turning yellow?
In December or January it usually means too much water or blocked drainage. From late February onward, yellowing lower leaves are normal and tell you harvest is near.
Can garlic grow indoors?
Leaves, yes; bulbs, rarely. A bright windowsill with about 4 hours of sun gives a steady supply of greens, but bulbs need full outdoor sun and winter cold.
How many bulbs does one clove give?
One. A clove grows into a single bulb, which holds several new cloves. Greens come as a bonus on the way.
Next pot to try: spring onions in pots and water, which share garlic’s season. More ideas sit in Zero-Waste Kitchen.
