Choose the method by herb

The right method depends on the stem, not a tender-versus-woody label alone. Oregon State University Extension recommends upright water storage for parsley, cilantro, mint, oregano, and sage. University of Minnesota Extension also describes a damp-towel method for refrigerated herbs.

HerbPractical starting methodWhat to watch
Cilantro and parsleyStems in water, leaves above the waterline, loosely covered in the refrigeratorSubmerged leaves, crowded stems, or murky water
Mint, oregano, and sage with long stemsStems in water in the refrigerator; use a damp wrap if the bunch will not stand wellCrushed leaves or condensation trapped against the bunch
Rosemary, thyme, and tarragonBarely damp towel in a clean bag or container in the refrigeratorA towel that is dripping wet or completely dry
Dill, chives, and short loose stemsBarely damp towel in a clean bag or container in the refrigeratorBending, bruising, and wet clumps
Intact basil stemsStems in water at room temperature, away from heat and direct sunChilling damage, wilting, dark or watery leaves, and decay

These are starting points, not guarantees. A Pacific Northwest Extension storage guide lists about one week for parsley and cilantro and 7 to 10 days for fresh herbs in general. The guide calls those times useful guidelines rather than set rules. A bunch that was bruised, warm, or already yellowing may decline much sooner.

How to use the refrigerated jar method

Oregon State's cilantro guide gives the clearest version of this method: refrigerate the bunch upright in water and cover it loosely. The leaves stay out of the water while the cut stems can take up moisture.

  1. Choose a clean, stable jar that will not tip when the refrigerator door or shelf moves.
  2. Remove decayed leaves and trim damaged stem ends. Strip leaves that would sit below the waterline.
  3. Add enough clean water to cover the lower stems, not the leaves.
  4. Stand the bunch loosely in the jar. Do not cram in enough stems to block air between them.
  5. Cover the leaves loosely and refrigerate. Check the bunch whenever you use it, and replace water that becomes cloudy or dirty.

You do not need a special herb keeper or a precise cutting angle. Clean water, uncrowded stems, cold storage, and regular checks do the work. If leaves are packed below the water or the jar smells sour, clean the jar and inspect the bunch for decay.

How to use the damp-towel method

Short stems and sturdy sprigs are often easier to wrap than stand in a jar. Start with a clean towel that feels slightly damp but does not release water when squeezed. Lay the herbs in one loose layer, fold the towel around them, and refrigerate the bundle in a clean zip-close bag or container.

Check for condensation instead of sealing the bundle and forgetting it. Replace a towel that becomes dirty or wet, and lightly dampen one that has dried out. If the herbs were washed before storage, dry their surfaces first. A humid wrap can slow wilting, but free water trapped against leaves encourages breakdown.

This method is useful for rosemary, thyme, and tarragon because their short side stems are awkward in a jar. It also works for loose chives and dill. Do not press the bag flat or stack heavy food on top of it; bruised herbs lose aroma and decay faster.

Why basil is the exception

Basil is sensitive to refrigerator cold. The University of Minnesota harvest guide recommends keeping cut basil stems in water at room temperature. It gives five days as an estimated shelf life. UC Davis postharvest guidance also identifies basil as chilling sensitive.

Put intact stems in a clean jar with the leaves above the water. Keep it away from a sunny window, stove, dishwasher vent, or other warm spot. Check the water and leaves daily, and plan to use the bunch within roughly five days. That estimate is a meal-planning aid, not permission to keep deteriorating basil.

Room-temperature water is for an intact bunch of cut stems. FDA's general produce guidance says perishable herbs and all purchased pre-cut or packaged produce belong in a clean refrigerator at 40°F or below. Refrigerate chopped basil, pesto, and any package whose label calls for refrigeration.

Wash before use, or dry thoroughly before storage

FDA advises rinsing fresh produce under running water before preparing or eating it. Leave soap, detergent, and commercial produce wash for other jobs. Dry the herbs with a clean cloth or paper towel after washing. Rinsing can reduce surface bacteria, but it does not eliminate them.

For cilantro, Oregon State recommends rinsing just before use. This keeps extra water out of the storage jar and avoids trapping wet leaves under a cover. If you prefer to wash a whole bunch as soon as it comes home, drain it well and let surface water dry before setting up the jar or towel.

Packages marked "pre-washed" or "ready-to-eat" can be used without another wash. Keep herbs that may be eaten raw above raw meat, poultry, and seafood in the refrigerator, and use clean hands, tools, jars, and towels.

When should you use, trim, or discard herbs?

Freshness fades before every bunch becomes rotten. The University of Minnesota advises choosing herbs that are crisp, bright, and free of dry brown or yellowed areas. Mild wilting, dry edges, and weaker aroma signal quality loss. Trim those parts and use the sound leaves soon, preferably in a cooked dish where perfect texture matters less.

What you seeWhat it meansWhat to do
Leaves are limp but dry, with no mold or slimeWater loss and lower qualityTrim dry parts and use the sound leaves promptly
A few yellow or bruised leavesLocalized quality declineRemove them and inspect the rest of the bunch
Murky jar water or a soaked towelThe storage setup needs cleaningDiscard decayed pieces, wash the container, and replace the water or towel
Slime, watery breakdown, visible mold, or a rotten odorDecayDiscard the affected bunch and clean the container

UC Davis describes bacterial soft rot as a slimy breakdown and notes that fungal decay can cause watery tissue and visible spores. FDA advises throwing away produce that looks rotten. Do not use a calendar date, smell, or appearance as proof that mishandled food is safe; when a product has been recalled or its temperature history is suspect, follow the recall or discard guidance.

Freeze sound surplus for cooked dishes

Freezing is useful when the herbs are still sound but will not be used fresh. Texture softens after thawing, so frozen herbs fit soup, sauce, stew, or cooked filling better than a salad garnish.

Oregon State recommends removing clean, dry cilantro leaves from the main stems, freezing them in a single layer on a tray, and moving the frozen leaves to a labeled airtight container. Minnesota Extension also describes freezing whole leaves or sprigs in labeled bags, or freezing chopped herbs in ice-cube trays with water.

Freeze only herbs you would still use today. Freezing does not reverse mold, slime, or decay. For flavor choices after storage, compare fresh and dried herbs. For more produce-storage planning, see how to organize food in the refrigerator.
