Apartment gardening means growing plants without a garden — in pots on a balcony, in containers by a window, or on a sunny sill. It is the only kind of gardening many people can do, and it works well if you match the plants to the light you actually have rather than the light you wish you had. A sunny balcony can grow tomatoes, peppers and herbs; a shady one can grow lettuce, spinach and ferns; a bright windowsill can grow a herb garden all year. This guide covers the rules, the light, the containers and the crops that suit apartment life.
Start by checking the rules and the structure. If you rent, check your tenancy agreement and ask your landlord about balcony planting, because some agreements restrict it. If you are in a block of flats, check the building rules: some do not allow pots on balcony rails, hanging baskets over the edge, or anything that could fall. Check the weight limit of your balcony before you fill it with large pots of wet soil — wet soil is heavy, and a balcony is not designed to hold the weight of a garden bed. Never place pots on a narrow rail where they could fall, and make sure nothing can drip or fall onto people below. Water carefully so it does not run onto a neighbour's balcony.
Light: the deciding factor
Light decides what you can grow. Watch your balcony and windows through a day and count the hours of direct sun. A south-facing balcony in the northern hemisphere gets the most sun and suits tomatoes, peppers, chillies, basil and other sun-lovers. An east-facing balcony gets morning sun and suits most vegetables and herbs. A west-facing balcony gets strong afternoon sun, which is good but can overheat pots. A north-facing balcony gets little direct sun and suits leafy greens, herbs such as mint and parsley, and shade-tolerant flowers and ferns. If your windows are small or shaded by other buildings, a windowsill herb garden and shade-tolerant houseplants are a better bet than vegetables — see our windowsill gardening guide and our indoor herb garden guide.
If light is limited, a grow light can help, especially in winter. A simple LED grow light over a shelf of herbs or seedlings can make the difference between plants that survive and plants that thrive, and our grow lights guide explains how to choose and use one in general terms, while the grow light calculator helps you work out coverage for your space. Do not expect a grow light to turn a dark flat into a greenhouse: it works best as a supplement for a bright windowsill, not as a replacement for real daylight.
Containers for apartments
Choose containers that suit a small, shared space. Lightweight plastic pots, fabric grow bags and wooden troughs are easier to move and put less load on a balcony than heavy terracotta or stone. Every container must have drainage holes, and every container needs a saucer or tray underneath so water does not drip onto the balcony floor or a neighbour below. Self-watering pots are worth considering in a flat, because they hold a reservoir of water and keep plants watered for days — useful if you work long hours or travel. Use a good potting mix, not garden soil, which is too heavy and drains badly in pots — our potting mix recipe gives a simple homemade mix. See our container gardening guide for the full detail on pots, soil and watering.
Wind is a real problem on balconies, especially on higher floors. Wind dries pots out fast, snaps tall plants, and can blow light pots over. Choose low, wide pots rather than tall narrow ones, group pots together so they shelter each other, and use a windbreak such as a trellis, a screen or a row of tough plants on the windward side. Stake tall plants such as tomatoes firmly, and avoid top-heavy plants in exposed spots. If your balcony is very windy, focus on low, tough crops such as herbs, lettuce and strawberries rather than tall tomatoes.
What to grow in an apartment
Herbs are the best apartment crop: basil, parsley, chives, mint, thyme and rosemary all grow well in pots, need little space, and are used fresh in cooking almost every day. Mint must be grown in its own pot, because it spreads aggressively — see growing mint, growing basil and growing rosemary. Salad leaves, spinach, radishes and spring onions are fast, easy and productive in troughs — see growing lettuce, growing spinach and growing radishes. Cherry tomatoes, chillies and peppers grow well in large pots on a sunny balcony — see growing tomatoes. Strawberries grow well in pots, troughs and hanging baskets, and they are easy to pick — see growing strawberries. For flowers, petunias, geraniums, marigolds and trailing lobelia suit pots and baskets — see growing marigolds. Houseplants such as pothos, spider plants and snake plants suit indoor spaces with less light, and many are covered in our houseplant guides.
Grow what you eat. A small balcony should be filled with the herbs and salads your household uses every week, not with crops nobody likes. Cut-and-come-again lettuce and herbs give months of harvest from one planting, which is ideal when space is limited. Sow a little and often — a small trough of lettuce every two or three weeks — so you always have something ready to pick. Our small space gardening guide covers succession sowing and vertical growing in detail.
Watering, feeding and pests in a flat
Pots dry out fast, especially on a sunny or windy balcony, and a pot in full sun on a hot day may need water daily. Water in the morning, water the soil rather than the leaves, and check the soil with a finger before watering. Empty saucers after watering so pots are not standing in water, which rots roots. Feed container plants regularly through the growing season with a balanced liquid feed, because a pot's food runs out quickly, but feed herbs lightly — they taste better in poorer soil. Mulching the surface of pots with gravel or bark helps hold moisture in.
Pests still find balcony gardens: aphids, whitefly and spider mites are the most common. Check the undersides of leaves regularly, knock aphids off with water, and remove badly affected leaves. Avoid sprays indoors or on a balcony where spray could drift to neighbours, and use the pest identifier helper if you are unsure what you are looking at. Bring tender plants indoors before the first frost, and use the frost date calculator to check your local dates. If you are unsure what will grow in your conditions, check your local extension service for advice.
Common mistakes
The most common apartment gardening mistakes are overloading a balcony with heavy pots, putting pots where they can fall, choosing sun-loving crops for a shady balcony, using pots with no drainage, forgetting to water in wind and sun, and growing crops nobody eats. Another is starting too big: a balcony crammed with pots is hard to water, hard to move around, and hard to enjoy. Start with three to five pots, learn what your light and wind allow, and add more as you gain confidence. A small balcony garden you can manage is far better than a large one that becomes a chore.
Frequently asked questions
Can I grow vegetables in a flat with no balcony?
Yes, if you have a bright windowsill. Herbs, salad leaves, spring onions and chillies can all grow on a sunny sill, and a grow light can help in winter. A north-facing flat with little direct sun will suit herbs such as mint and parsley and leafy greens better than fruiting crops such as tomatoes.
How do I stop water dripping onto my neighbours?
Use saucers or trays under every pot, water slowly so the soil absorbs it, and empty saucers after watering. Self-watering pots also reduce dripping. Never water so heavily that water runs off the balcony, and avoid watering from above where it can splash over the edge.
What is the best herb garden for an apartment?
Basil, parsley, chives, mint and thyme in separate small pots on the sunniest windowsill or balcony you have. Mint must have its own pot. They are used fresh almost daily, they need little space, and they forgive beginner mistakes. See our indoor herb garden guide for the full setup.
Do I need a grow light for apartment gardening?
Only if your light is limited. A bright south-facing windowsill or balcony usually needs no extra light in summer. In winter, or in a flat with small or shaded windows, a grow light over herbs or seedlings helps. See our grow lights guide for how to choose and use one.
Is balcony gardening safe in a rented flat?
Usually yes, if you follow the rules: check your tenancy agreement and building rules, respect weight limits, keep pots off rails and away from edges, and make sure nothing can fall or drip onto people below. If in doubt, ask your landlord or building manager before you start.
