Moderately firm lettuce heads with a reddish tinge on the edges of the leaves.
Lettuce thrives well in all types of garden soil. Sow flat and thin every 2-3 weeks in order to harvest leaves year round. Transplant once lettuce is about 5 cm in height. Avoid planting too deep. Lettuce thrives particularly well in moderate temperatures and abundant light. Frequent watering is crucial to promote rapid growth and tender leaves. Water carefully once the lettuce firms up and the heads begin to close.
