How to Grow Deer Tongue
Lactuca sativa
Deer Tongue lettuce offers a tender, sweet flavor that thrives in cool weather. Gardeners prize this variety for its exceptional heat tolerance and bolt resistance, making it an easy choice for extended harvests from early spring through late fall.
Starting Deer Tongue: indoors or direct sow?
🏠 Start indoors 3 weeks before your last spring frost, then move the seedlings outside.
If starting indoors, harden off seedlings gradually before transplanting them outdoors once they are two to six weeks past the last frost date.
Soil, care & harvest
Prepare loose, fertile soil with a pH between 6.0 and 7.5 to encourage strong roots. As a cool-season crop, sow seeds directly outdoors or start indoors two to six weeks before your last expected frost date. Press seeds gently into the soil surface without covering them deeply, as they need light to germinate effectively within seven to twelve days.
Space plants ten to twelve inches apart to ensure proper air circulation and head formation. While Deer Tongue is drought tolerant once established, provide one to one-and-a-half inches of water weekly during active growth. Apply a light layer of mulch around the base to retain moisture and suppress weeds, but avoid piling it against the stems.
Monitor for slugs and aphids, though this variety is naturally resistant to most pests. Downy mildew and bacterial leaf spot are rare issues; ensure good airflow to prevent fungal growth. Harvest outer leaves when the plant reaches maturity in forty-five to fifty-five days after sowing, allowing for a continuous supply of fresh greens.
