How to make your vegetables last longer in the refrigerator

Intact. Cut off any soft or bad bits before storing

Whole. Keep them whole when you store them. Chop and prepare them just before serving

Dry. Keep them dry. If you wash leaves or other vegetables, dry them before putting them in the refrigerator. If you put them in a container, lay them on a paper towel

Vacuum. There are several vacuum pump containers available. Whilst they are fiddly and take up more space, they are effective. They let you store all kinds of fresh foods, not only salads, for several times longer

I use a vacuum pump to keep my opened bottles of wine intact. If there is half a bottle left after a meal, I insert the rubber stopper that has a one-way valve in it, attach the hand pump, and pump until feeling resistance. The wine will last for several days in the vacuum
