When to Pick Swiss Chard
Harvest Swiss chard when outer leaves are 8 to 12 inches long, often 30 to 45 days after sowing for baby leaves and 50 to 60 days for full size. Cut each stem at the soil line. Leave the inner leaves. The plant will keep making new ones until a hard freeze, and in mild winters it can hold even longer.
Chard handles heat better than spinach, so August harvests are normal. Hot spells can make leaves tough; pick smaller and keep water even. See the Swiss chard plant page and the Swiss chard growing season guide.
How to Harvest
- Take a few outer leaves per plant, two times a week.
- Cut, do not tear, so the crown stays intact.
- Baby chard at 4 to 6 inches is tender for salads.
- If the plant bolts (sends a flower stalk), harvest the remaining leaves. Flavor holds better than bolting lettuce.
Fall Planting
You can still sow chard in August in zones 6 to 8 for a fall crop. It is more heat-tolerant than spinach, which makes it a good late-summer green. Space plants about 12 inches apart.
Next Steps
Pick the outer leaves this week even if you do not need a full bunch. That keeps the plant producing. If a row is exhausted, replace it with fall lettuce or garlic.
