Seasonal planting calendar for terrace gardens in India — month-by-month guide
A seasonal planting calendar for Indian terrace gardens saves you from sowing tomatoes in June (when they'll fry in heat), planting coriander in July (when monsoon fungus will kill it), or expecting spinach in September (when the soil is still warm). India's climate does not follow a single European-style growing season — it runs three overlapping crop seasons, each with its own logic, and terrace gardeners in cities like Lucknow, Delhi, Kanpur, and Jaipur need to time their sowings carefully to get a harvest worth the effort.
This guide covers all 12 months in detail: what to sow, what to transplant, what to harvest, and what tasks to focus on. It also explains the three Indian growing seasons, maps out regional differences from Punjab to Tamil Nadu, and lists the best crops for each season in grow bags and rooftop containers. Whether you have a small balcony or a 500 sq ft terrace, this calendar gives you a practical framework to follow month by month.
The three Indian growing seasons explained
Indian agriculture and home gardening both run on three seasons. Understanding these is the foundation of everything else in this calendar.
Kharif — the monsoon season (June to October)
Kharif crops are sown at the start of the southwest monsoon, usually in June, and harvested between September and November. These crops love heat and moisture. In Lucknow, the monsoon arrives around June 20–25 most years; in Kerala it arrives by June 1. On your terrace, kharif is the season for chilli, okra (bhindi), ridge gourd, bottle gourd, bitter gourd, brinjal (baingan), cowpea, and herbs like basil and lemongrass.
The main challenge on a terrace during kharif is waterlogging. Grow bags and containers drain better than garden beds, which is actually an advantage — but you still need to ensure drainage holes are clear and that your terrace doesn't pool water around pots. Heavy rain can also leach nutrients from grow bags fast, so fortnightly liquid feeding with a diluted NPK fertiliser (like Iffco Sagarika or a homemade jeevamrit solution) keeps plants going through the wet months.
See our best crops for monsoon season guide for a complete rundown.
Rabi — the winter season (November to March)
Rabi crops are sown after the monsoon ends, typically in October–November when soil temperatures drop below 25°C. These crops grow slowly through the cool winter and are harvested from January onward. North India — Lucknow, Delhi, Agra, Kanpur — gets cold nights (4–8°C in January) that are ideal for leafy greens, root vegetables, and brassicas.
In grow bags on a terrace, rabi is the most rewarding season. Tomatoes, spinach, methi (fenugreek), coriander, carrots, radish, peas, cauliflower, and palak all thrive in containers through October–February. Pest pressure is low compared to kharif, humidity is manageable, and the crops grow steadily without bolting.
For North India-specific guidance, see our winter vegetables for North India guide. For tomatoes specifically, read the tomato growing guide.
Zaid — the summer season (March to June)
Zaid is the short hot-weather season between rabi harvest and kharif sowing. For terrace gardeners in North India, this is the hardest season — Lucknow hits 44–46°C in May–June. Most cool-season crops have bolted or died by March, and it's too early for monsoon crops. Shade cloth (50% density) over your terrace helps. Some cucumbers, bitter gourd, and heat-tolerant herbs (tulsi, lemongrass) can handle zaid. Start chilli and capsicum seedlings indoors in May for transplanting at kharif onset.
South Indian gardeners (Tamil Nadu, Karnataka, Kerala) have a gentler zaid because coastal humidity moderates peak temperatures — they can continue growing tomatoes and some leafy greens through March–April.
Month-by-month planting guide
January
Primary season: Peak rabi
What to sow: Radish (20-day varieties like Pusa Chetki work even in January), fenugreek (methi), spinach, coriander (in shaded spots).
What to transplant: Tomato seedlings started in November are ready to move to final 20L grow bags now. Cauliflower and cabbage transplants if started in December.
What to harvest: First tomatoes from October transplants, spinach, methi, radish, carrot (if sown in October–November), peas.
Key tasks: Keep 2L of water per plant per day for tomatoes in grow bags — cold air dries pots faster than warm soil. Watch for aphid clusters on tomato stems; a spray of neem oil (5 ml per litre of water, every 5–7 days) controls them without chemicals. Protect pots from frost in Lucknow/Delhi using old newspaper wraps around grow bags on nights below 5°C.
February
Primary season: Late rabi — warm up begins
What to sow: Start chilli and capsicum seeds indoors now in seedling trays filled with cocopeat + perlite (1:1). Lucknow gardeners who start chilli in February get transplant-ready seedlings by April. Also sow cucumber and ridge gourd seeds in small 2L pots — they'll be ready for bigger bags by March–April.
What to transplant: Final batches of tomato transplants. Last chance for leafy green transplants in North India before heat arrives.
What to harvest: Peak harvest month for rabi crops. Tomatoes, spinach, coriander, methi, peas, carrots all come in together.
Key tasks: Pinch off tomato suckers weekly to channel energy into fruit. Begin hardening off chilli seedlings that were started in January. Feed grow bags with a compost top-dress (2–3 handfuls of vermicompost per 20L bag) before the growing season transitions.
March
Primary season: Zaid begins / late rabi ends
What to sow: Bitter gourd, cucumber (sow directly in 20L bags now), some heat-tolerant okra varieties. In South India, start kharif crops like okra and cowpea outdoors from mid-March.
What to transplant: Chilli seedlings started in January (they should be 10–12 cm tall with 4–6 true leaves). Move to 15–20L grow bags.
What to harvest: Final rabi harvests — spinach tends to bolt in March heat, so harvest everything remaining. Tomatoes continue if planted in October; they'll slow by April.
Key tasks: Set up shade cloth (50% block) over the terrace before April heat hits. Lucknow temperatures routinely cross 38°C by late March. Shift sensitive pots (spinach, lettuce) to east-facing positions that get morning sun only. Deep-water all grow bags — smaller 10L bags may need 1L of water twice daily in warm spells.
April
Primary season: Zaid — hot and dry
What to sow: Okra (bhindi) can be direct-sown in 20L bags in North India now. Bitter gourd and ridge gourd if not done in March. Basil seeds germinate fast in April heat (5–7 days at 28–30°C).
What to transplant: Chilli and capsicum transplants from February sowings.
What to harvest: Cucumbers (from March sowings), bitter gourd, late tomatoes. Most rabi crops are finished.
Key tasks: Shade cloth is essential. Mulch the top of grow bags with dry leaves or cocopeat to reduce moisture loss — 20L grow bags can lose 1.5–2L to evaporation daily at 40°C without mulching. Move pots off exposed concrete (heat radiates up from the floor) using wooden pallets or plastic stands.
May
Primary season: Peak zaid — peak heat
What to sow: Start kharif seedlings indoors now so they're ready for June–July transplanting. Sow chilli, brinjal, tomato in seedling trays indoors — do not direct-sow outdoors yet. Okra can still be direct-sown in North India through mid-May if you can protect seedlings from afternoon heat.
What to transplant: Hold off on sensitive transplants — the heat is extreme. Move only established okra, bitter gourd, and basil into final containers.
What to harvest: Okra (from April sowings), bitter gourd, cucumbers, basil (pinch regularly to delay flowering).
Key tasks: Water twice daily — morning and early evening. Never water in the afternoon on hot days; water droplets on leaves under direct sun can cause scorch. Install drip rings or use self-watering pots if you travel. Check grow bags daily for soil shrinkage away from bag walls — this channels water down the sides rather than into the root zone. See our what to grow in June in India guide for transition planning.
June
Primary season: Kharif begins — monsoon sowing
What to sow: This is the start of the main kharif sowing window for North India. Direct-sow okra, cowpea, ridge gourd, and bottle gourd into 20L grow bags. Sow basil and lemongrass for herb gardens. In Lucknow, wait until after June 20 (typical monsoon onset) before sowing moisture-sensitive crops like gourds, since pre-monsoon dry spells can wilt young seedlings.
What to transplant: Chilli, brinjal, and tomato seedlings started in May are ready to move to final bags. Also see our chilli and capsicum guide for transplanting tips.
What to harvest: Okra, bitter gourd, cucumbers from zaid plantings.
Key tasks: Clear grow bags of finished rabi or zaid plants and refresh potting mix. Top up each 20L bag with 3–4 litres of fresh cocopeat + compost before replanting kharif crops. Check that drainage holes at the base of all bags and pots are unblocked before monsoon arrives.
July
Primary season: Peak kharif — full monsoon
What to sow: Second round of okra, ridge gourd, bottle gourd, and cowpea for extended harvest. Sow bitter gourd seeds directly in 20L bags if not done in June. See our what to plant in July guide for the full kharif crop list.
What to transplant: Any remaining chilli and brinjal seedlings. Late tomato transplants in South India (Tamil Nadu gardeners can transplant tomatoes in July–August for a November harvest).
What to harvest: First flush of okra (40–50 days from June sowing), ridge gourd, cowpea.
Key tasks: Stake all climbing plants — gourd vines in grow bags need a strong trellis or wall support. Use jute twine rather than nylon, which cuts into soft stems. Remove yellowing lower leaves on chilli plants to improve airflow and reduce fungal risk during high-humidity monsoon months. Feed every 14 days with diluted NPK liquid fertiliser (19:19:19 at 1g per litre of water) since heavy rain leaches nutrients from grow bags quickly.
August
Primary season: Mid kharif — steady monsoon
What to sow: Start early rabi seedlings indoors in August — tomatoes and capsicum sown in seedling trays in late August will be transplant-ready by October. This is one of the most important sowing windows of the year for North Indian terrace gardeners.
What to transplant: Nothing major this month — focus on kharif crop maintenance.
What to harvest: Ridge gourd, bottle gourd, bitter gourd, okra in full production. Chilli plants (from June transplants) begin fruiting.
Key tasks: Watch for powdery mildew on gourd leaves in August — it appears as white dusty patches. Spray a solution of potassium bicarbonate (5g per litre) every 7 days as a preventative. If fruit borer damage appears on chilli (holes in fruit), switch to Bacillus thuringiensis (Bt) spray — available as Delfin or Dipel from agro-supply stores in Lucknow.
September
Primary season: Late kharif / pre-rabi prep
What to sow: Sow rabi crops that prefer a longer head start — coriander, fenugreek, and spinach can be direct-sown in grow bags from late September in North India as temperatures begin to ease.
What to transplant: Tomato seedlings sown in August can be transplanted into final 20L grow bags from mid-September onward. This is prime time for the Lucknow tomato season.
What to harvest: Okra, gourds, chilli, brinjal all in peak production.
Key tasks: Begin refreshing potting mix in grow bags that will be used for rabi crops. Remove old kharif plants only once they stop producing — okra and chilli can continue into October if healthy. Deep clean empty bags: empty, dry in sun for 3 days, mix in fresh vermicompost, and refill.
October
Primary season: Kharif ends / rabi begins
What to sow: Prime time for rabi direct-sowing: radish, spinach, methi, coriander, palak. Sow peas (matar) in North India from mid-October — they need a long cool season to flower.
What to transplant: Tomato transplants from August sowings go to final bags this month — this is the main transplanting window for the Lucknow tomato season. Cauliflower and broccoli transplants if started in September.
What to harvest: Final kharif harvest — chilli, brinjal, okra, gourds. Harvest everything before the first cold snap.
Key tasks: Clear kharif plants. Refresh all grow bags. Begin setting up windbreaks for exposed north-facing terraces in Lucknow — cold northerly winds in November–January can stress plants in grow bags faster than in-ground plants. Arrange taller bags (gourds, tomatoes) to shelter smaller herb pots.
November
Primary season: Established rabi season
What to sow: Direct-sow carrots, radish, turnip, and beet in deep grow bags (minimum 30 cm depth). Sow methi and spinach for regular harvest. Start tomato seedlings indoors for a February transplant if you want a late-winter crop.
What to transplant: Second round of tomato transplants into final bags. Cauliflower, cabbage transplants.
What to harvest: First radish (20-day varieties), spinach, methi, coriander (from September/October sowings). Tomatoes from October transplants show first flowers.
Key tasks: Monitor for aphids in the cool dry weather — they cluster on new growth of tomatoes and brassicas. Neem oil spray (5 ml per litre, every 5 days) keeps populations down. Reduce watering frequency now — grow bags retain moisture longer in cool weather and overwatering causes root rot.
December
Primary season: Deep rabi — cool and dry
What to sow: Final sowing of radish and leafy greens before the coldest weeks. Sow pea seeds if not done in October–November.
What to transplant: Move any remaining tomato transplants (from October sowings) to final bags before cold nights begin.
What to harvest: Spinach, methi, radish, coriander in full swing. Peas begin podding. First tomatoes from October transplants in warmer years.
Key tasks: Protect grow bags from night temperatures below 5°C in Lucknow/Delhi. Wrap bags with old gunny sacks or bubble wrap on cold nights. A layer of dry straw mulch on top of grow bags insulates roots. Check soil moisture by finger-dip: water only when the top 2 cm is dry — winter overwatering is the most common reason rabi crops fail on terraces.
Regional differences across India
Different cities and states have different monsoon timing, temperature ranges, and frost risk. Use this table to adjust the calendar above to your location.
| Region | Cities | Key adjustment |
|---|---|---|
| North India | Lucknow, Delhi, Kanpur, Agra, Jaipur | Primary reference throughout this guide. Frost risk Nov–Jan. Kharif June 20 – Oct. Rabi Oct – Mar. Hot zaid Apr–Jun. |
| Punjab / Haryana | Amritsar, Ludhiana, Chandigarh, Hisar | Slightly earlier kharif sowing (June 10–15 in Punjab). More severe winter — protect grow bags below 3°C. Mustard and garlic are popular rabi additions. |
| Western India | Ahmedabad, Rajkot, Jodhpur | Hot and dry. Skip most zaid crops except okra — extreme heat in May. Monsoon arrives later (July in Rajasthan). Rabi season is excellent — cool dry winters are ideal for tomato and leafy greens. |
| South India | Chennai, Bengaluru, Hyderabad | Northeast monsoon (Oct–Dec) is the main rain season — kharif timing shifts. Bengaluru's moderate climate allows tomatoes nearly year-round. Tamil Nadu gardeners transplant tomatoes July–August for a Nov–Jan harvest. No frost risk. |
| East India | Kolkata, Patna, Bhubaneswar | High humidity year-round. Fungal disease pressure is higher — increase neem oil spray frequency to every 5 days. Monsoon arrives May–June. Winters mild; some rabi crops (peas, carrots) need higher-altitude areas for best results. |
| Maharashtra | Mumbai, Pune, Nashik | Mumbai coastal humidity makes kharif pest pressure high. Pune's cooler elevation is better for rabi crops. Monsoon arrives early (June 1–5 in Mumbai). |

Season-specific tips
Surviving the monsoon (June–October)
Terrace gardens face different monsoon challenges than balcony or indoor gardens. Standing water on the terrace floor damages grow bag fabric and creates mosquito breeding spots. Raise all bags onto wooden pallets or plastic crates — even a 10 cm elevation makes a difference. Inspect drainage holes weekly; cocopeat can block them if it washes down over time.
Nutrient leaching is a real problem when 50–100 mm of rain falls in a week. Even well-buffered cocopeat potting mixes lose nitrogen and potassium fast. Feed with liquid fertiliser (diluted NPK 19:19:19 at 1g per litre, 500 ml per 20L bag) every 14 days throughout kharif. If leaves yellow in August despite rain, add iron chelate (like Multiplex Chelamin, ₹120–150 for a 100g packet from Dehaat or local agro stores).
Watch for fungal issues from mid-August: downy mildew on cucumbers, leaf curl on chilli, blight on tomato. Space containers 30–40 cm apart for airflow. Remove affected leaves immediately and do not compost them.
Getting through winter without frost damage (November–February)
Most of North India does not get hard frost, but temperatures below 5°C for several nights can damage tomato flowers, chilli roots in thin grow bags, and tender transplants. Key protection steps:
Move 10–15L grow bags indoors or under a transparent polycarbonate sheet on forecast frost nights. For large 20–25L bags that cannot be moved, wrap the sides with bubble wrap and cover the top with an old cotton bedsheet or shade cloth. Do not use plastic sheeting directly on leaves — it traps moisture and causes fungal disease. Remove covers by 9 AM once temperatures rise.
Avoid overwatering in winter. Rabi crops in grow bags need watering every 2–3 days on average, not daily. Check by pushing a finger 3 cm into the mix — if it feels moist, skip that day's watering. Root rot from overwatering kills more rabi crops on terraces than frost.
Managing summer heat (March–June)
The zaid season on a North Indian rooftop is brutal. Black grow bags in direct sun can reach 50–55°C at the soil surface, which is lethal for roots. Switch to white or silver-coloured grow bags for zaid, or wrap black bags in white fabric. Move bags to east-facing positions that get morning sun and afternoon shade.
Water at 6 AM and 6 PM — never midday. Mulch the top of each bag with 3–5 cm of dry straw or cocopeat to cut evaporation by 40–50%. If you're away for the weekend, a simple wick irrigation system (a 2L bottle with a small hole in the cap, inverted into the soil) can keep moisture levels stable for 24–36 hours.
Shade cloth rated at 50% block (available from Dehaat or Ugaoo for ₹80–150 per sq metre) is the single most effective investment for zaid terrace gardening. It drops leaf surface temperature by 6–8°C and reduces watering needs significantly.
If your plants show symptoms like wilting, leaf spots, or stunted growth at any season, use the Plant Doctor for a quick photo-based diagnosis before reaching for a spray.
Frequently asked questions
What should I plant on my terrace in January in Lucknow?
January is peak rabi season in Lucknow. Plant or maintain tomatoes (from October transplants), spinach, methi, coriander, and radish. You can still sow radish (20-day varieties) and methi directly into 10L grow bags. Tomatoes will be fruiting if planted in October. Keep water at 1–2L per 20L bag per day and watch for aphids on young leaves — spray neem oil at 5 ml per litre every 5–7 days.
Which vegetables grow best in monsoon on a terrace?
Okra (bhindi), ridge gourd, bottle gourd, bitter gourd, brinjal, and chilli are the best kharif crops for terrace containers in India. All thrive with 20L grow bags, good drainage, and fortnightly liquid feeding. Avoid leafy greens like spinach and coriander during the peak monsoon months (July–September) — the high humidity causes damping off and fungal leaf diseases quickly.
Can I grow tomatoes year-round on a North Indian terrace?
Not easily. Tomatoes need 18–28°C for fruiting. In Lucknow, the ideal window is October transplant → January–March harvest (rabi), and a shorter August transplant → November harvest window. From April through August, heat and humidity cause flower drop and blossom-end rot. Focus tomato growing on the October–March window for best yields. For full guidance, see our tomato growing guide.
How big a grow bag do I need for each vegetable?
The minimum sizes that work on terraces: 20L for tomatoes, chilli, capsicum, brinjal, okra, and gourds; 10L for methi, spinach, coriander, and small herbs; 30 cm depth minimum for carrots and radish (use purpose-made deep grow bags or large buckets). Shallow decorative pots under 8L rarely produce a meaningful harvest for fruiting vegetables — they overheat, dry out too fast, and restrict root development.
What is the best time to sow chilli seeds in India?
For North India (Lucknow, Delhi, UP), sow chilli seeds in seedling trays in February for an April transplant into final bags, or in May for a June–July transplant timed to the monsoon. Chilli sown in May and transplanted at monsoon onset benefits from rain and moderate temperatures for establishment. See our chilli and capsicum guide for step-by-step sowing instructions using cocopeat and perlite.
How do I protect my terrace plants from summer heat in May–June?
Install 50% shade cloth over the terrace, shift pots to east-facing positions (morning sun only), mulch grow bag tops with 3–5 cm of dry straw or cocopeat, and water twice daily at 6 AM and 6 PM. Use white or silver grow bags rather than black ones — black bags in direct sun can reach 55°C at the soil surface. Raise bags off the concrete floor onto wooden pallets to prevent heat transfer from the terrace floor.
