Babyleaf is a convenient way of describing the optimum growth stage of many different leafy vegetables when cut to provide an individual leaf for salads. This is normally within the range 8-14cm in size. The popularity of bagged salads in recent years has risen sharply due the excellent quality of the components, and over 90% of households in the UK regularly buy their salads in this form. Viridis Hortus screen many hundreds of varieties for their suitability for the babyleaf market, examining leaf size and shape, speed of growth, size of cut area (normally stem thickness) ease of harvest, flavour, colour and general appearance, and of course shelf life after harvest.
Mustard 'Red Giant' is lovely as a baby leaf, raw or cooked in stir fries and soups. This is the spiciest of the mustard leaves and tastes of horseradish.
Sow these little and often and use them in a baby leaf salad, or full size in stir fries. I love a winter salad made up of these mixed with milder lettuce, topped with a crispy skinned and succulent duck breast.
They look and taste fantastic and will grow outside through the winter, even under snow.
Mustard grows best in a sunny position in a fertile soil. It can be sown directly into open ground or can be planted into grow bags. If grown for babyleaf it can be sown into small containers or even windowboxes. Choose a well-drained container that's at least 10 to 15cm (4 to 6in) deep. Containers may need to be watered a couple times a day when temperatures begin to warm. If growing micro-greens, seeds can be planted in shallow flats and harvested about 10 to 21 days after planting. If given adequate light, they can also be grown indoors during the winter.
Sowing: Sow under cover February to May or sow direct April to October
Mustard seeds can be sown practically year round. Plant little and often, every two weeks for continuous supply. Seeds germinate in 5 to 10 days at temperatures between 7 to 30°C (45 to 85°F)
Sow sparingly in shallow drills 6 to 12mm (¼ to ½ in) deep. Space seeds 2.5cm (1in) apart for cut-and-come-again salad or 20 to 25cm (8 to 10in) for whole plant production. Adequate spacing is most important when growing plants to full size. This is easy to accomplish by simply thinning plants as they begin to get crowded in the garden.
Mustard greens are primarily a cool season vegetable and are at their peak in late spring to early summer. Keep well watered especially in summer. Hot weather causes the plants to bolt and their greens to turn unpleasantly bitter.
An autumn crop is often planted because mustard is frost-resistant and easily overwinters in temperate areas. Protect late sowings with cloches and the plants will keep growing throughout the winter and continue to grow vigorously when temperatures warm and daylight increases.
Harvesting: 20 days for babyleaf, 45 days to maturity
Mustard plants can be harvested for baby leaf once the leaves are 5cm (2in) tall. For milder leaves, pick young, they are best cropped at around 15cm (6in) for salads.
The plants will grow to around 30 to 45cm (12 to 18in) tall. Mature leaves can be boiled or steamed or braised in a pot with a little butter and garlic.
Use scissors or a knife rather than pulling the leaves to avoid damaging the plant. Keep picking regularly to prevent flowers running to seed. Pull and compost the plants once hot weather arrives in the summer, as mustard greens become tough and bitter
Suitable for the vegetable garden, allotments and containers.
Be prepared to water well and supplement feed with high-potash feed during season. Regular feeding is recommended.
