Growing more in a small garden
A small garden can be surprisingly productive. A single 4 × 8 ft raised bed can grow a steady supply of salad greens, herbs and a few tomato plants, and a sunny balcony can hold a dozen containers. The trick is to plan the space, build good soil and grow upwards where you can.
This section covers raised beds, flower beds, container and balcony gardens, and vegetable garden layouts for small yards, with honest costs and step-by-step tips.
1. Start with the sun
Most vegetables and many flowers need at least six hours of direct sun a day. Watch your space through a full day before you build anything. Shadier corners suit leafy greens, herbs like mint and parsley, ferns and hostas.
2. Build better soil
Raised beds and containers let you control the soil, which is often the biggest win in a small garden. Fill beds with a mix of good topsoil and compost, and top up each season as the soil settles. Our raised bed soil calculator tells you exactly how many cubic feet, cubic yards or bags to buy.
3. Grow up, not out
Trellises, arches and wall planters turn vertical space into growing space. Climbing beans, peas, cucumbers and small squash all grow happily up a trellis, which leaves the bed below free for lower crops.
4. Mulch to save water and weeding
A layer of mulch around plants holds moisture, keeps soil temperature steady and smothers weeds. Two to three inches is a common depth for most beds. Use the mulch calculator to work out how many bags you need.
Small garden ideas to try
- Raised beds: a 4 ft wide bed lets you reach the middle from both sides without stepping on the soil.
- Flower beds: a curved edge and plants in groups of three or five look fuller than single plants in a row.
- Container and balcony gardens: choose pots with drainage holes, group them for humidity, and check the weight limits of balconies.
- Vegetable garden layout: put tall crops on the north side of the bed so they do not shade shorter ones.
- Companion planting: flowers such as marigolds and herbs such as basil are popular companions for vegetables and bring in pollinators.

Small garden FAQ
How deep should a raised garden bed be?
Many vegetables and flowers grow well in 8 to 12 inches of soil. Deep-rooted crops such as carrots, parsnips and tomatoes do better with 12 inches or more.
How much soil do I need for a 4 × 8 raised bed?
At 12 inches deep, a 4 × 8 ft bed holds 32 cubic feet of soil, which is about 1.2 cubic yards or 22 bags of 1.5 cubic feet. Many gardeners add around 10% for settling.
What can I grow in a small garden?
Salad greens, herbs, radishes, bush beans, cherry tomatoes, peppers and strawberries all do well in small beds and containers. Climbing crops such as peas and cucumbers save space when grown up a trellis.
How much sun does a vegetable garden need?
Most fruiting vegetables need at least six hours of direct sun a day. Leafy greens and many herbs can cope with less.
