How to Sow and Plant
+
Sow Butterhead Lettuce seeds indoors from February to March in a seedbed under glass, or directly outdoors from March to August in rows spaced 30 cm apart. Cover seeds lightly with soil, as they require shallow sowing. Maintain soil moisture and looseness for optimal conditions. After seedlings reach 2-4 cm, thin them to 30 cm spacing within the row to allow room for firm, tender heads to develop. Ideal germination occurs at 15-20ºC; avoid temperatures above 20ºC to reduce bolting risk. Choose a shady position in warm weather to support successful sprouting and growth.
Maintain moist, loose soil and keep temperatures below 18ºC to encourage steady growth and prevent premature bolting. Ensure plants have adequate spacing of 30 cm to allow airflow and healthy development. Provide partial shade during warmer days to protect tender leaves and extend the harvest period. Regularly remove excess seedlings when they reach 2-4 cm tall to promote strong, compact heads. Consistent moisture and cooler conditions will support the formation of firm, succulent butterhead lettuce heads, ideal for fresh salads throughout the warmer months.
