Harvesting

Lettuce heads can be picked 50 - 60 days after sowing. When cutting, remove the entire head at the base, the outer leaves may be loose, but the inner head should feel tight and firm. Once the head bolts (flowers), the lettuce taste bitter. Any stress (mostly dry and heat) can also lead to bitterness! Soak the leaves in salt water to help recover crispiness after picking and remove any critters.

Slugs and snails feed on the heads at night which results in ragged, chewed leaves and weak plants. Use commercial slug traps and bait or you can pick the slugs off the plant by hand. Keep the leaves dry to prevent rotting.
