Planting & Care

Sow Red Romaine lettuce seeds directly in the garden as soon as the soil can be worked in spring, or in late summer for a fall crop. Plant seeds 1/4 inch deep and keep the soil evenly moist until germination. Thin seedlings to 8-12 inches apart to allow heads to develop fully. For a continuous harvest, succession sow every 2-3 weeks.

Provide consistent moisture and mulch to keep roots cool. Lettuce benefits from partial shade in warmer climates to prevent bolting. Harvest outer leaves or whole heads when they reach desired size. With proper care, you can enjoy fresh, homegrown Red Romaine throughout the growing season.
