Planting & Care

Sow Komatsuna seeds directly in the garden or in containers about 1/4 inch deep, spacing seeds 1-2 inches apart initially. Thin seedlings to the recommended spacing once they are a few inches tall. For a continuous supply, sow seeds every 2-3 weeks during the growing season. Keep the soil evenly moist but not waterlogged, and provide consistent moisture to encourage tender growth.

Komatsuna thrives in cool weather and can be planted in early spring and again in late summer for a fall crop. Mulch around plants to retain moisture and suppress weeds. Harvest outer leaves first or cut the entire plant at the base for a cut-and-come-again harvest. Monitor for common pests like aphids and flea beetles, and use row covers if necessary.
