Rhubarb is among the first fresh harvests from home gardens. You can start picking the tart, red stalks as early as April and May. Traditionally, the harvest ends on June 24, St. John’s Day. Until then, the question remains: How do you store rhubarb properly?
Due to its tart flavor, rhubarb is especially popular for pies, compotes, or jams. Once harvested, the stalks quickly lose freshness. To keep the vegetable crisp and flavorful longer, it’s important to store rhubarb correctly.
Never Use Metal or Aluminum Foil for Storage!
Rhubarb contains a lot of oxalic acid. This acid gives the plant its distinctive taste and serves as a natural pest deterrent. This is a crucial fact for storing this vegetable. Oxalic acid can react with metal or aluminum foil, altering the taste of the rhubarb. Additionally, substances from the material can leach out. Therefore, never store rhubarb with aluminum foil or uncoated metal, as advised by the Consumer Center.
Store Rhubarb in a Cool Place
The best place to keep rhubarb is in a cool location. Suitable options include the vegetable drawer of the refrigerator or a cool cellar. Leave the rhubarb uncut and loosely wrap it in a damp cloth. Do not remove the skin, as it protects the stalks from drying out.
Avoid airtight packaging. Moisture can quickly accumulate, promoting mold growth.
How Long Does Rhubarb Stay Fresh After Harvest?
Freshly harvested rhubarb lasts about three days in the refrigerator. Rhubarb is mostly water. If stored too warm or dry, the vegetable quickly loses moisture. It’s important to minimize moisture loss; otherwise, the stalks become soft and fibrous. A damp cloth can help prevent this.
The rule of thumb is: Process rhubarb right after harvesting or purchasing for the best flavor.
By the way: Slightly soft rhubarb is usually still edible. It’s suitable for compote or jam, for example. However, be cautious with moldy spots or if the stalks emit an unpleasant odor. In that case, it’s better to discard the vegetable.

Can You Freeze Rhubarb?
Yes, you can freeze the plant. To do this, wash the stalks thoroughly, peel them, and cut them into pieces. Then blanch or cook the vegetable. Rhubarb keeps for about twelve months in the freezer.
Tip: To prevent the pieces from sticking together, you can pre-freeze them on a tray and then transfer them to a freezer bag or container.
How to Recognize Fresh Rhubarb
To store rhubarb well, always look for fresh stalks at the supermarket. You can recognize them by their firmness and tautness, with a smooth, slightly shiny surface. The vegetable should also shine with vibrant colors: Depending on the variety, the stalks range from green to deep red.
If you find soft spots and dried-out ends, it’s a sign that the rhubarb is no longer fresh.
