Chard is easy to care for once established, needing regular watering in dry spells to keep the leaves tender and prevent bolting. Remove weeds around the plants to reduce competition, and apply a mulch to help retain soil moisture.
Harvest outer leaves regularly by cutting them near the base, allowing the central growth to keep producing fresh leaves over a long season. Both young leaves and mature stems can be picked, with frequent harvesting encouraging further growth.
Chard is hardy and will often stand through winter, especially with a little protection, giving a valuable supply of greens when other crops are scarce.
