Red Oakleaf Lettuce Overview

Oakleaf lettuce is cool weather loose-leaf crop, so make sure they are not exposed to too much sun or very hot weather. The flavour of freshly picked lettuce from the garden beats bought lettuces any day. Lettuce plants also serve as a wonderful ornamental in gardens and use the different textures and colors to make patterns in your vegetable patch!

Common problems with Red Oakleaf Lettuce

Slugs and snails chew smooth-edged holes in outer leaves. Collect them with a gloved hand during drizzly weather, evenings or trap them in pit traps baited with beer. You also can spray cold coffee on slug-infested plants to stop feeding. Birds love the red varieties too. Remove leaves touching the soil to prevent rot spreading.

How to harvest Red Oakleaf Lettuce

Harvest as soon as the leaves are large enough to use. Don't wait too long, as the lettuce eventually develops a bitter flavor and woody texture. Harvest older leaves first, using clean kitchen shears to cut the individual leaves from the stem or whole plants to ground level. Harvest about 30 - 45 days after sowing. Any heat or dry stress will lead to bitterness!
