Lettuce Seeds,
Chadwick's Rodan

Chadwick's Rodan lettuce should be planted in early spring or late summer for a fall harvest. This variety does well in USDA Hardiness Zones 4-9. You can start seeds indoors 4-6 weeks before the last expected frost date or directly sow them outdoors 2-4 weeks before the last frost. For fall planting, sow seeds in late summer, ensuring there is enough time before the first frost for full growth​​.

To start Chadwick's Rodan lettuce indoors, sow seeds 1/4 inch deep in seed trays filled with a quality seed-starting mix. After germination, thin seedlings to 8 inches apart before transplanting them outdoors. Gradually harden off seedlings by exposing them to outdoor conditions over a week before transplanting them to their permanent location​. For direct sowing, plant seeds 1/4 inch deep as well, in well-prepared soil, keeping them moist until germination.

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​.

• 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.
