Growing Salad Leaves in Containers

Crop

Salad leaves are quick, compact and ideal for containers, bringing fresh harvests close to the kitchen. You can sow small batches from spring into autumn and pick individual leaves as needed. Troughs, window boxes and shallow pots work well, especially where a vegetable bed is not available.

How to do it

Fill a trough or shallow pot with peat-free multipurpose compost, leaving a 2 cm watering gap. Sow seed thinly across the surface, cover lightly and water with a fine rose. Keep the compost consistently moist but not waterlogged. Once seedlings are large enough, thin crowded patches and use the thinnings in salads. Sow a fresh small container every two or three weeks for a continuing supply. Place summer pots where they receive morning sun and some afternoon shade if possible, as heat encourages plants to bolt. Harvest outer leaves with scissors, leaving the centre to regrow, or cut whole rows a few centimetres above the compost.

Best plants

Mixed salad leaves, loose-leaf lettuce, rocket, mizuna, mustard greens, baby spinach and pak choi all suit containers. Choose cut-and-come-again mixes for repeated picking. In cooler or shadier spaces, lettuce, spinach and parsley are reliable. Radishes and spring onions can share a deeper trough, provided there is enough room and regular water for every crop.

Tips

Sow little and often rather than one large batch, as leaves are best when young and tender. Keep pots close to a tap or water butt because dry compost makes flavour sharper and hastens bolting. Protect young sowings from slugs where necessary. Wash harvested leaves and pick them just before serving for the freshest texture.
