Summer Vegetables to Grow in Pakistan: What to Sow Feb to April
The summer vegetables to grow in Pakistan and North India are the heat lovers: bhindi (okra), lauki, tori, karela, tinda, kheera (cucumber), melons, chillies, brinjal and chaulai. In the Punjab plains most go in from mid February to March; Karachi can start earlier, Islamabad a few weeks later, and Multan must sow early because April is already hot. The trick is getting them flowering before the May and June heat, which drops flowers and stalls fruit.
The short version
- Official window (Punjab): February to March for okra, cucumber, melons and watermelon; mid February to April for karela; March to April for tinda; brinjal nursery mid February
- Easiest for beginners: bhindi, lauki, chaulai
- Sun: 6 to 8 hours; less sun means fewer flowers
- Pots: 15 to 20 litres (12 inch) for bhindi and chillies; 25 to 40 litres or a grow bag for gourds
- Watch out for: heat over about 32°C during flowering, which cuts fruit set in tomato, pepper and the gourd family

Why March sowing matters more than the plant you pick
Summer crops need warm soil to germinate, so January sowing outdoors in Lahore or Delhi fails in cold, damp soil. Wait too long and the plants are just starting to flower as afternoons climb past 40°C. Extension researchers at South Dakota State University note that heat above about 32°C can leave tomato and pepper pollen unable to fertilise flowers, and that cucumbers and squash produce more male flowers in hot weather, so fewer fruit form. Our summers make that the normal May experience. Sowing in the right fortnight puts flowers ahead of the worst heat.
What to sow, by zone
| Vegetable | Karachi / Multan | Lahore / Islamabad | Notes |
|---|---|---|---|
| Bhindi (okra) | Plant Feb / Plant Feb | Plant late Feb to Mar / Plant Mar | Toughest in heat; second sowing June to July |
| Lauki (bottle gourd) | Plant / Plant | Plant / Plant Mar | Needs a trellis or roof edge to climb |
| Tori (ridge or sponge gourd) | Plant / Plant | Plant / Plant | Pick young; old fruits turn fibrous |
| Karela (bitter gourd) | Plant / Plant | Plant to April / Plant | Soak seed overnight to speed germination |
| Tinda | Maybe / Plant | Plant Mar to Apr / Plant | Dislikes Karachi’s humidity; mildew-prone |
| Kheera (cucumber) | Plant / Maybe | Plant / Plant | Bitter and misshapen in extreme heat |
| Melon, watermelon | Maybe / Plant | Maybe in pots / Maybe | Need space and big containers; ground is better |
| Brinjal (baingan) | Plant / Plant | Plant / Maybe | Raise a nursery mid February, transplant after a month or so |
| Chillies | Plant / Maybe | Plant / Plant | Flowers drop in peak heat, fruit again in autumn |
| Chaulai (amaranth leaves) | Plant / Plant | Plant / Plant | Fastest; leaves in a few weeks |
| Tomato | Maybe / Skip | Maybe / Maybe | A spring sowing struggles in heat; autumn is better |
Month windows follow the Punjab Agriculture Department’s variety and sowing table for the plains; Karachi and Multan notes reflect their earlier warmth.
How to sow summer vegetables in pots and beds
- Soak hard seeds. Bhindi, karela, lauki and tori seeds sprout faster after 8 to 12 hours in plain water.
- Sow direct where possible. Gourds dislike root disturbance. Push two seeds about 2 to 3 cm deep, and keep the stronger seedling.
- Use a rich, airy mix. About half garden soil, a quarter compost and a quarter cocopeat or coarse sand, with a handful of extra compost for gourds. See our potting mix ratio guide.
- Give climbers support from day one. A trellis, string net or roof railing for lauki, tori and karela. Our rooftop gourd trellis guide covers the build.
- Mulch once seedlings are a hand tall. Dry leaves or straw keep the soil cooler and cut evaporation sharply in April and May.
- Feed lightly, then for fruit. Compost at sowing; once flowers appear, a fertiliser lower in nitrogen and higher in potassium supports fruit. Too much nitrogen gives giant leaves and few gourds.
Hand pollinate gourds at breakfast
If your lauki or tori makes plenty of flowers but tiny fruits shrivel, bees are not visiting enough. Gourd flowers open early and close fast in heat. Before 9 am, pick a male flower (thin stalk, no bump), peel back its petals, and dab its pollen onto the centre of a female flower (the one with a tiny gourd behind it). One minute a day often turns a fruitless vine into a productive one on a high roof.
Common summer problems and the first organic response
| Problem | Likely cause | First response |
|---|---|---|
| Flowers drop, no fruit | Heat, poor pollination | Hand pollinate early; afternoon shade net |
| White powder on leaves | Powdery mildew | Remove worst leaves, water at the base, improve air flow |
| Small green or black insects under leaves | Aphids | Water jet, then a mild soap or neem spray in the evening |
| Holes and maggots in gourds | Fruit fly | Pick and bin damaged fruit; cover young fruit with paper bags |
| Yellow mosaic on bhindi leaves | Whitefly spread virus | Pull infected plants early; yellow sticky cards for whitefly |
When to harvest
Pick bhindi when pods are about finger length and snap cleanly; a day too late and they turn woody. Lauki and tori are best young and tender, when a fingernail dents the skin easily. Karela is picked green and firm before it yellows. Cucumbers are ready when evenly green and firm. Regular picking keeps plants flowering.
Neem oil is for plants only and must never be given to children by mouth; store sprays high and in original bottles (our neem oil spray guide gives the ratio). For any chemical spray, read the label, wear gloves and a mask, keep children and pets off until dry, and wait the stated days before picking. A lauki or tori that tastes unusually bitter should be spat out and thrown away, not cooked or juiced; bitter gourd-family fruits other than karela can cause serious stomach illness. Empty water from saucers and trays to stop dengue mosquitoes breeding, and water rooftop plants at dawn, not in the midday sun, for your own sake too.
Summer vegetable questions
Which summer vegetables to grow in Pakistan?
Bhindi, lauki, tori, karela, tinda, cucumber, chillies, brinjal, chaulai and melons. Sow most of them from February to March in the plains.
Summer vegetables to grow in Pakistan list for pots?
Bhindi, chillies, chaulai and brinjal in 15 to 20 litre pots; lauki, tori and karela in bigger tubs or grow bags with a trellis.
Summer vegetables to grow in Pakistan for beginners?
Bhindi and chaulai are the most forgiving, followed by lauki. They germinate fast and handle heat better than tomatoes or cucumbers.
Can I sow vegetables in April in Lahore?
Yes, chaulai, karela, tinda and a late bhindi still work. Melons and tomatoes sown in April usually struggle as May heat arrives.
Why are my bhindi plants not growing?
Cold soil, too little sun or waterlogged pots. Bhindi needs warm soil and 6 or more hours of sun. Sowing too early in February is a common cause.
Why do my lauki flowers fall off?
The first flowers are mostly male and fall naturally. If female flowers also drop, the cause is usually poor pollination or heat. Hand pollinate in the morning.
Can tomatoes be grown in summer in Pakistan?
Spring tomatoes can work if they flower before May. In peak heat fruit set fails. Most plains gardeners get better results from an autumn crop; see our tomato in a pot guide.
Which plants to avoid at home in summer?
Avoid sowing leafy winter crops like dhania and palak; they bolt in heat. Also avoid tiny pots on hot roofs, which cook the roots.
When is the second summer sowing?
The Punjab Agriculture Department lists second sowings of bhindi in June to July and cucumber in July, once the monsoon cools nights.
