How to Grow Cool-Season Salad Greens

Seeds sprout within 5-10 days. Seedlings develop their first true leaves and establish a shallow root system.

Keep soil moist but not waterlogged. Provide cool conditions (50-65°F). Thin seedlings to proper spacing once they have 2-3 true leaves. Provide bright light to prevent leggy growth.

Plants develop multiple leaves and form a rosette or head structure. Leaves expand rapidly in cool weather.

Maintain consistent moisture and cool temperatures. Begin leaf harvesting when plants are 4-6 inches tall (for cut-and-come-again greens). Provide balanced fertilization every 2-3 weeks if needed. Watch for bolting in warm spells.

Plants produce abundant harvestable leaves. Outer leaves are ready for picking while inner leaves continue developing.

Harvest outer leaves regularly to encourage continued leaf production. Use scissors or hands to avoid damaging the plant. Most varieties can be harvested multiple times. Keep soil consistently moist during this phase.

Plants reach full size with dense leaf production. Varieties like romaine and endive form tight heads.

Continue regular harvesting to delay bolting. Reduce watering slightly if rain is adequate. Monitor for pests and diseases. In warmer weather, provide afternoon shade.

Plants develop a central flower stalk, and leaves become bitter and tougher. This marks the end of the harvest season.

Once bolting begins, quality declines rapidly. Harvest remaining leaves and remove plants to make room for fall or summer crops. Cool weather delays bolting; hot weather accelerates it.
