Lettuce Seeds,
Gustav's Salad

Gustav's Salad lettuce can be sown indoors 4-6 weeks before the last expected frost date. Transplant seedlings outdoors after the last frost, ensuring they are hardened off properly. For a fall harvest, start seeds in late summer. This variety is suitable for USDA hardiness zones 3-11, making it quite versatile.

Sow seeds 1/4 inch deep in seed trays or directly in the garden, spacing the rows about 12 inches apart. Sow in thick bands for baby greens or space 8 inches apart for head lettuce. For continuous harvests, sow seeds every two weeks. In areas with high bird activity, consider using netting to protect the seeds. It’s beneficial to water the soil thoroughly before sowing, especially on hot days, to enhance germination rates​​.

Maintaining soil fertility is key to thriving lettuce. Use a balanced fertilizer, preferably one high in nitrogen, such as fish emulsion or composted manure. Regularly check for pests like aphids and slugs, and apply organic pest control methods if needed. Harvest the outer leaves as needed or cut the entire head at maturity, around 50 days after planting. Providing shade during peak summer heat can help prevent bolting and ensure tender leaves​.

• 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.
