The most common reason fresh herbs quickly turn yellow and spoil in the refrigerator is that their leaves are thin and vulnerable to water loss. The leaf surfaces of herbs such as parsley and dill are much thinner than those of vegetables; this makes them lose water faster and more prone to rot when moisture collects on the surface. The second important factor is bagging them while they are wet after washing; water left on the leaves turns into trapped moisture inside the bag and speeds up spoilage.
Why does the thin structure of the leaves matter so much?
Unlike thick-skinned vegetables, fresh herb leaves have a very thin surface structure; they release water quickly, and the leaves may begin to wilt slightly within just a few hours. Cells that lose water gradually change color and turn yellow. The thin leaves are also vulnerable to mechanical damage; herbs crushed or bruised inside a bag darken and spoil much faster than those that remain intact.
Why does storing herbs wet after washing speed up spoilage?
If herbs are bagged after washing without being dried thoroughly, water droplets left on the leaves evaporate and condense inside the bag, creating a consistently damp environment. This moisture provides ideal conditions for mold and bacteria to grow. For this reason, drying the herbs thoroughly before storage or leaving them out to air-dry for a few hours greatly reduces moisture buildup in the bag.
Which herbs spoil faster than others?
Thin-leaved herbs such as dill and parsley may turn yellow and spoil within a few days, while woody-stemmed herbs such as thyme and rosemary can stay fresh for weeks. Mint also spoils quickly because of its thin leaves. This difference comes from the water-holding capacity of the leaf surface; woody-stemmed herbs lose water much more slowly.
Does storing herbs in a glass of water really work?
Cut the stem ends of bunches of parsley or dill and place them in a glass of water, then loosely cover the leaves with a bag. Like cut flowers, this significantly slows water loss from the leaves. When the glass is kept in the refrigerator and the water is changed every day, this method usually keeps the herbs fresh for up to a week. In the glass method, it is important not to crowd the herbs so their leaves touch the bag or water, allowing air to continue circulating.
Other ways to keep fresh herbs longer
Wrapping washed and thoroughly dried herbs in a paper towel and storing them in a loosely closed container in the refrigerator can produce results similar to the glass method because the paper absorbs excess moisture. Finely chop the herbs and freeze them in ice cube trays with a small amount of water as another way to preserve them long term. Frozen herbs cannot be used as a garnish in the same way as fresh herbs, but they retain most of their aroma when added during the cooking stage of soups, sauces, and other dishes. Freezing some of a large bunch is a practical way to prevent waste from spoilage. Sorting through herbs as soon as you bring them home and removing crushed or yellowed leaves may also help the rest of the bunch last longer; one spoiled leaf may quickly spread to neighboring leaves it touches. Although checking and sorting the bunch leaf by leaf takes some time, it is a small investment that can prevent the rest of the bunch from spoiling and being discarded entirely.

Maydanozu sap uçlarını suya batırıp üzerine gevşek bir poşet geçirdikten sonra buzdolabına koydum, iki hafta boyunca hiç sararmadan taze kaldı; daha önce aynı demet birkaç günde çürüyüp atılıyordu.
