In North India, winter is actually a good growing season for many vegetables and flowers. But cold nights, occasional frost in some areas, foggy days and dry winds still affect plants in pots, which are more exposed than plants in the ground. Our guide to starting a balcony garden in a rented flat covers the basics; this is the winter version.

Know which plants need protection

Tropical plants such as some ornamental foliage plants, and summer vegetables like chillies and brinjal, struggle in cold weather. Winter crops and hardy flowers thrive.

Move pots for light and warmth

Winter sun is lower and weaker. Move pots to the sunniest spot you have, and closer to the wall, which stores warmth from the day and protects plants from wind. Group pots together so they shelter each other.

Protect from cold nights

  • Cover sensitive plants with a light cloth or old bedsheet on very cold nights, removing it in the morning
  • Lift pots off cold floors with bricks or pot feet
  • Wrap pots in sacking or old cloth to insulate roots

Water less, but do not forget

Plants need less water in winter because evaporation is lower and growth slows. Water in the morning so the soil is not cold and wet overnight. Check soil before watering; overwatering in winter often causes root rot.

Clean leaves

In smoggy cities, a film of dust and soot can settle on leaves and reduce the light they receive. Wipe large leaves gently or rinse plants occasionally.

What to grow in winter

  • Vegetables: spinach, methi, coriander, radish, carrots, lettuce, peas and spring onions
  • Flowers: marigold, calendula, petunia, pansy and dianthus
  • Herbs: coriander and mint, with tulsi brought into a sheltered spot

Feed the soil

Add compost before sowing winter crops. Leaf mould made from autumn leaves, as described in our leaf composting guide, makes an excellent addition to winter potting mixes.

Plan for spring

Winter is a good time to clean pots, repair trellises and save seeds. A little preparation now means a balcony ready to burst into life when the warmth returns.

Frequently asked

Do I need to buy anything to get started?

No. Every method here begins with what is already in your cupboards. We only recommend a purchase when something has genuinely worn out, and we say what it should cost.

How do you test the things you write about?

Minimum four weeks of ordinary household use, with notes. For anything involving energy or money we use a plug-in meter and record the readings before and after.

Are your recommendations paid for?

Never. Brands cannot buy placement. Some outbound links are affiliate links, which we mark, and they do not change what makes the list.

What if a method doesn't work in my home?

Write to us. A surprising amount of our best material comes from readers explaining why something failed in a flat, a shared house or a very cold winter.
