How to Grow Chard

When To Sow: March-April (indoors);
April-August (direct seed)
Harvest: May–November

Germination: 7–14 days
Full Sun to Partial Shade.

Chard (also known as Swiss chard or silverbeet) thrives in rich, well-drained soil with a pH between 6.0 and 7.0. It’s a versatile and forgiving crop, making it a great option for beginner gardeners.

Starting Indoors

Sow seeds in modules or small pots from March to early April at a depth of ½ inch (1.25 cm). Cover with soil and firm gently. Once seedlings have at least two true leaves, pot on into individual containers. Harden off gradually before transplanting outdoors from late April onward.

Direct Seed

For a longer harvesting window, you can direct sow outdoors from mid-April through to late August. Sow thinly in rows spaced 30–45cm (12–18”) apart. Thin seedlings to 20–30cm (8–12”) once established. Successional sowing every few weeks ensures a continuous crop into autumn.

Chard doesn’t mind a bit of heat but will benefit from some afternoon shade during hot summers to prevent wilting and leaf scorch.

Maintenance

• Keep beds weed-free to reduce competition. Mulching helps retain moisture and discourage weed growth.
• Water consistently, especially during dry spells. While chard is drought-tolerant once established, irregular watering can lead to tough, bitter leaves.
• Watch for slugs and snails on young seedlings. Use cloches or organic deterrents if needed.
• Feed soil with compost or manure before planting. A midseason liquid feed (like seaweed extract) helps boost growth.
• Remove flowering stalks to extend leaf production.

Harvesting

Begin harvesting baby leaves at 10–15cm (4–6”) tall, or let them mature and pick outer leaves as needed. Always harvest from the outside in to let the centre regrow.

You can also cut the whole plant 2 inches above the base—it often regrows.

Harvest regularly to avoid tough, stringy leaves.

Companion Planting

Chard grows well with carrots, onions, beans, radishes, and brassicas. It benefits from the shade and weed suppression provided by cabbage family members. Avoid planting near potatoes, which may compete for nutrients.
