Lettuce Seeds,
Devil's Ear

Devil's Ear lettuce is best planted in early spring or late summer for a fall harvest. It will do well in USDA Hardiness Zones 4-9. Start seeds indoors 4-6 weeks before the last expected frost or sow them directly outdoors 2-4 weeks before the last frost. For a continuous supply, practice succession planting every two to three weeks throughout the growing season​.

Sow seeds 1/4 inch deep in seed trays with a quality seed-starting mix to start indoors or directly sow outside in well-prepared soil. Sow in thick bands for baby greens or space farther apart, about 8 inches, for head lettuce. Keep the soil moist until germination occurs. If starting indoors, harden off seedlings by gradually exposing them to outdoor conditions over a week before transplanting them to their permanent location.

Devil's Ear lettuce requires partial shade. Maintain consistent soil moisture, providing about 1-2 inches of water per week. Mulching can help retain moisture and regulate soil temperature. Fertilize with a balanced fertilizer if necessary, but rich, organic soil typically does 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​.

• Lettuce is a self-pollinating annual, making it an easy crop for seed saving.
• Choose the best and healthiest plants and allow them to send up flower stalks.
• Once seed heads are dried and have turned a yellowish-tan color, cut the entire stalk and place in a bag.
• Crush the seed heads in the bag and separate the chaff.
• Store in an airtight container in the refrigerator for up to 4 years.
