Leafy vegetables usually can't be stored for a long time. If you put them in the refrigerator directly, they will turn yellow soon and their leaves will be wet and rotten. The most important thing to preserve this kind of vegetables is to retain water and avoid leaf rot at the same time. The simplest way is to use old newspapers, spray some water on the leaves, then wrap them in newspapers and put them in the fresh-keeping room of the refrigerator with the stems down in an upright position, which can effectively prolong the preservation time. You can also wrap the leafy vegetables after wetting the kitchen paper towels, and then put them in the refrigerator for cold storage, which can also slow down the water loss and keep them fresh.
