How to preserve lettuce? Lettuce is a healthy addition to any meal, but it can wilt quickly. The good news is, it’s fairly easy to preserve fresh lettuce for weeks or even months by implementing these simple tricks and techniques. By removing excess oxygen, sealing in freshness and keeping the lettuce away from other produce that gives off ethylene gas, you can make your greens last much longer.

What deficiency causes yellowing of leaves?

Wash your lettuce leaves thoroughly. Then, fill a sink or a bowl with cold water and submerge the leaves. Gently swish the leaves in the water to remove any dirt or grit that might be stuck on them. Remove the leaves and rinse them again before drying them completely. This can be done in a salad spinner or by laying them on a paper towel. Leaves that are damp or have a lot of grit will wilt more quickly than dry ones.

After washing and drying your lettuce, wrap it tightly in a sheet of paper towel or in a plastic bag. This will absorb some of the moisture that can cause it to wilt and spoil. It’s also a great way to keep your lettuce from bruising while in storage.

To keep your lettuce crisp for a long time, put it in a sturdy container that will protect the delicate leaves from bruising or being squished by other refrigerated foods. Line the container with a layer of paper towels, then scatter your lettuce on top. Then, seal the container in a vacuum sealer and label it with the date. This is a great trick to use for mesclun mixes and tender leafy vegetables like endive, arugula and watercress.
