Swiss Chards in Barrelhill Green

Sow seeds around 19th February - 10th July in shallow drills at 2–3 cm. Sow a fresh batch every 21 days for a long picking season, and thin the seedlings later rather than crowding the row.

Once the seedlings have their first true leaves, thin them to the strongest plants at 30 cm apart. Use the thinnings in the kitchen if they come away cleanly, and water the row after thinning to settle the roots.

From 14th May, check plants often for slugs and snails, especially in damp weather. Put down barriers, traps, or hand-pick at dusk, and keep the row clear of weeds and debris so young leaves are less exposed.

From 21st May to 19th February, water whenever the soil starts to dry at the surface. Keep moisture even, especially in warm spells, because dry checks can make plants run to seed and leaves turn tough.

Start cutting from 9th July once plants are well rooted and have enough leaf growth. Pick the outer leaves first and leave the centre growing, or cut the whole plant if you want a one-off harvest. Keep picking through to 21st March and the plants will keep producing new leaves.
