These colourful leafy greens belong to the Chenopodioideae family, which also includes beets and spinach. Swiss chard is much easier to grow than spinach. It thrives in any soil and has much better resistance to bolting during dry weather.
Most varieties overwinter reasonably well. A single spring sowing can provide fresh leaves from July through to the following year. The coloured stalks and leaves of many varieties are decorative enough to grace the flower border.

Chards covers a range of leafy vegetables known by many common names, including ruby chard, spinach beet, leaf beet, sea kale, silver beet and perpetual spinach. True spinach is prone to bolting in dry weather but the chards and beets are fairly trouble free. They will last in the ground for over a year as cut and grow again, so a small row is all you need.
This highly decorative vegetable is perfect for borders and containers. Providing all year round colour and good nutrition.
Chards prefer a fertile, moisture retentive well cultivated soil to thrive well but will grow in almost any soil, even poor ones.
Follow standard crop rotation rules by sowing in a different place each spring to maintain healthy plants. Choose a sunny sheltered site. Prepare the bed the previous autumn by digging in plenty of well rotted manure or compost. Chards prefer alkaline conditions, so add lime if the pH is below 6.5.
Apply a general purpose fertilizer two weeks before sowing. Finely rake and firm the soil before sowing or planting.
Sow from the end of April to the end August.
Direct sow, 1in (2.5cm) deep in rows around 16in (40cm) apart. Gradually thin plants to 8in (20cm) apart.
Alternatively, sow them a few weeks earlier in modules, in an unheated greenhouse or cold frame. Transplant when large enough to handle. Spacing 8in (20cm) apart.
Leaf beets also grow well in large pots and containers.

Keep the bed weed-free and well watered in dry weather. Remove any flower buds as soon as they appear.
A spring or summer sowing should provide leaves right through to the following June, when the tired plants can be dug up to make way for the next crop.
Cloche in November for harvesting during the winter months.
Generally trouble free, except for slug damage to young leaves.
Harvest approximately 8 to 12 weeks after sowing (depending on variety). Pick leaves regularly to encourage fresh growth. Don't harvest all the leaves at one time but remove a few of the outer leaves from each plant.
Because chard can be harvested fresh, all year round, there should be no need to store it.
The sweet stalks (chard) and peppery leaves can be steamed as a vegetable or eaten raw in salads when young.
Steam the fleshy leaves and stalks for 20 minutes or chop them into sections and boil for 15 minutes.
