What Actually Shortens A Vegetable's Life In Your Kitchen

Most home storage problems come down to moisture, air and bad neighbours.

Vegetables deteriorate for a few predictable reasons, and knowing them lets you work out how to store something you have never bought before. They lose water and go limp. They sit in trapped moisture and spoil. They keep respiring and using themselves up, faster when warm. And some of them release a ripening gas that hurries along everything nearby, which is why a bag of ripening fruit next to your leaves is a quietly destructive arrangement. Separate the gassy ripeners from the sensitive greens and you solve a surprising number of problems at once.

From those causes the handling follows. Leaves want humidity without wet: wrapped loosely with a cloth to catch condensation rather than sealed in a bag with water pooling in the corner. Roots want cool and dark and no light, because light is what turns some of them green and bitter. Alliums and squashes want dry air and space around them, not a sealed drawer. Herbs with soft stems behave like cut flowers and are happiest standing in a little water. Anything already washed is on a shorter clock, because you have added surface water, so wash at the point of cooking rather than the point of unpacking.

Two more habits pay for themselves. Take vegetables out of the plastic they came in, or at least open it, because sealed plastic holds the moisture they release right against them. And trim before storing where it makes sense: leafy tops left on a root keep drawing water out of it, so separate them and use the tops in their own right. On anything to do with safe holding of food, follow current food safety guidance rather than kitchen lore, and when something looks or smells wrong, do not argue with it.
