This colorful‑leaf lettuce produces loose, ruffled leaves painted in rich reddish‑purple tones. Young tender leaves carry a mild, delicate flavor, making them an excellent choice for fresh salads, sandwiches and side dishes. Apart from edible value, its striking foliage also brings decorative visual interest to vegetable beds.
These vegetable seeds thrive under cool‑temperature conditions. High heat will trigger bolting and turn leaves bitter. Keep consistent soil moisture to encourage soft, tender leaf growth. You can harvest outer leaves gradually for repeated picking, instead of pulling the whole plant at one time. Good air circulation helps reduce leaf‑rot risk during humid growing periods. Planting Instructions Soil Preparation Choose sunny planting spots. Use fertile loose loam soil mixed with well‑rotted organic compost. Break up soil clumps for fine seedbed. Avoid waterlogged low‑lying areas. Neutral soil pH delivers best growth performance.
Seed Pre‑treatment No cold stratification required. Brief seed soaking for several hours can boost germination speed.
Sowing Method Sow in early spring or autumn. Scatter seeds thinly on soil surface and cover with a very thin soil layer. Keep 10‑15 cm spacing between plants after thinning. Both direct field sowing and indoor seed‑tray seedling raising work well.
Germination Condition Optimal germination temperature:12‑20°C. Seedlings emerge within 7‑12 days. Keep seed‑starting substrate slightly moist, avoid over‑watering.
Daily Maintenance Full sun or partial light shade is acceptable. Maintain even soil moisture; do not allow long‑term drought. Apply light‑dose nitrogen‑rich fertilizer during leaf‑growing stage. Remove weeds regularly. Watch for aphids and slugs. Harvest outer mature leaves continuously for extended picking time.

FAQ Q1: Why does lettuce turn bitter? A1: Continuous high temperature causes bolting, which brings bitter flavor; plant in cool spring or autumn. Q2: Can I pick leaves repeatedly? A2: Yes, harvest outer leaves and keep inner core intact, so the plant keeps producing new foliage. Q3: Is full sunlight mandatory for lettuce? A3: It tolerates light partial shade, yet adequate sunlight promotes vigorous leaf growth. Q4: How deep should lettuce seeds be buried? A4: Only cover with a thin layer of soil; too deep covering will suppress germination. Q5: What pests frequently trouble leaf lettuce? A5: Aphids and slugs are common threats, keep good ventilation and observe plant status frequently.
