Sow in thick bands for baby greens or space farther apart for head lettuce. Sow seeds directly into the garden at a depth of 1/4 inch. Thin seedlings to 8 inches apart to allow adequate growth. You can also start seeds indoors and transplant them later. For continuous harvests, sow seeds every 2-3 weeks. In areas with high temperatures, provide some shade to prevent bolting.

This lettuce variety requires full sun to partial shade, 4-8 hours of sun daily. The soil should be kept consistently moist but well-drained, with about 1-2 inches of water per week. Mulching can help retain moisture and regulate soil temperature. Fertilize with a balanced fertilizer if necessary, although rich organic soil may not need additional feeding. Protect plants from extreme heat using shade cloths and from pests with appropriate measures. Harvest leaves as needed or cut the entire head when mature​.
