When to Plant:
Directly sow seeds outdoors in mid spring.
Prepare the site several weeks prior to planting with potash or wood ash. Enrich the soil with plenty of compost, as chard needs adequate nutrition to thrive. It prefers full sun but can tolerate some shade.
Each plant should be 10-12 inches apart in rows 2 feet apart.
Swiss chard requires adequate amounts of water to grow well.
When to Harvest:
You can pick leaves after they have reached around 6 inches in length, usually about 60 days after sowing. For a continuous harvest, only pick the outer leaves.
