Planting Swiss Chard

Swiss chard is a cool weather crop, but can also tolerate warmer conditions, albeit with slower growing times. Plant seeds 1cm (1/2") deep, 5cm (2") apart with 45cm (18") between rows. Swiss chard prefers well-draining soil rich in organic matter, and performs best in full sun but will also tolerate partial shade.

Growing Swiss Chard

Once the seedlings reach 5cm (2") tall, thin them to allow roughly 15cm (6") between each plant. The thinned seedlings can be replanted elsewhere, or used in salads. Water consistently to prevent the flavour from becoming bitter; keep the soil moist but not wet, and consider mulching to help preserve moisture. Swiss chard doesn't require any fertilising, but could benefit from a balanced fertiliser a month after germinating.

Row covers can help to protect from pests such as slugs, snails, and birds. Additionally, check the underside of the leaves regularly for aphids.

Harvesting Swiss Chard

Plants can be harvested from once they reach 15cm (6") tall. Cut the outer leaves as you need them, 2cm (1") above the soil, as this will encourage new growth. Swiss chard can be stored loosely in a bag in the refrigerator after rinsing the leaves.
