How to Preserve Your Harvest
Harvesting vegetables and greens in autumn is a wonderful time. Naturally, you want to keep your produce fresh and flavorful for as long as possible. Here are a few key tips to help you properly store your harvest:

General Guidelines
- Storage Duration
Different vegetables have different shelf lives. Root vegetables and pumpkins can last up to 6 months in a cellar, while juicy vegetables last only a few weeks. The storage location also matters — vegetables usually keep longer in a cool cellar than in the refrigerator. - Cleaning and Preparation
Know which vegetables and greens can or should be washed and dried before storage — and which absolutely shouldn’t. As a rule, vegetables are only washed before eating or freezing. Always remove any damaged or decaying produce before storage. - Ideal Storage Conditions
Always consider the type of crop. In general, vegetables are stored in a cool basement or cellar, or in the refrigerator (vegetable drawer or freezer). - Individual Packaging
Ideally, each type of vegetable should have its own packaging — separate containers, boxes, or crates. In some cases, vacuum packaging is also a good option. - Plastic Contact
Avoid plastic bags unless they allow air flow — condensation can build up and lead to rot. Some exceptions apply, especially when using vacuum-sealable plastic containers. - Humidity Control
Some vegetables require specific humidity levels. In such cases, place a damp paper towel inside the packaging to help retain the right moisture. - Storage Check-ups
Regularly inspect your produce and remove anything starting to spoil. Rot spreads quickly and can ruin neighboring fruits and vegetables.
Root Vegetables (Potatoes, Carrots, Beets, Onions, Celery)
- Storage Time: 4–6 months. Celery: 1 month.
In the fridge: Potatoes last 2–3 months, carrots and celery 2–4 weeks. - Store in a cool, dry place at 0°C to 4°C. The ideal spot is a cellar or basement.
- Sweet potatoes should be stored at around +13°C — cold temperatures ruin the taste, so avoid the fridge.
- Avoid storing any damaged roots or those with blue discoloration. Remove any showing signs of mold or decay.
- Onions and garlic keep best in a dark, cool, dry place to prevent sprouting.
- Carrots and celery keep longer in containers with slightly damp paper.
- One of the best ways to store carrots is in boxes filled with sand. Stand them upright in the sand, which helps regulate moisture and prevents both drying out and rot.
Tomatoes:
- Store tomatoes at room temperature in a dark place until fully ripe. Then, you can move them to the fridge — but low temperatures may affect flavor.
- Do not wash before storing.
- Ripe tomatoes stay fresh for 3–5 days. After that, it’s best to freeze or preserve them.
- Make sure tomatoes are dry before storing.
- Store separately from other produce — they emit ethylene gas, which accelerates spoilage.
- Have a surplus of cherry tomatoes? Freeze them whole: wash, dry, and place them on parchment or a tray, then transfer to a freezer-safe container once frozen.
Cucumbers:
- Shelf life: 1–2 weeks. After that, it’s best to preserve or freeze them.
- Do not wash before storing. If dirty, simply wipe with a dry cloth.
- Store in a plastic bag or container with a damp paper towel inside, but leave it slightly open.
- Optimal refrigerator temperature: 7°C to 10°C.
- Keep cucumbers away from ethylene-producing fruits (like tomatoes, apples, bananas, apricots) to prevent early spoilage.
- To freeze: wash, dry, slice into rounds, freeze on a tray, then transfer slices to a freezer bag.
Eggplants and Bell Peppers
- Stay fresh for 1–2 weeks. Beyond that, preserve or freeze.
- Do not wash before storage — only before use.
- Store in the fridge in plastic bags.
- To freeze: wash, slice, and place in freezer-safe bags.
Pumpkins and Zucchini
- Fresh pumpkins store up to 3 months; zucchini: 2 weeks.
- Store in a cool, dry space.
- Pumpkins: 10°C to 15°C
- Zucchini: 0°C to 4°C
- Pumpkins: 10°C to 15°C
- Ensure the space is well-ventilated.
- Both can be washed, dried, sliced, and frozen for long-term use.
Broccoli, Cauliflower, and Other Cabbage Crops
- Stay fresh for 1–2 weeks.
- Do not wash before storing to avoid early wilting or rotting.
- Store in plastic bags in the fridge (0–4°C) or in a cool basement.
Fresh Herbs (Dill, Parsley, Basil)
- Fresh herbs keep for 1–2 weeks.
- To extend shelf life: place the stems in water and cover the herbs with a plastic bag, then store in the fridge.
- For freezing: wash, dry thoroughly, and turn the herbs frequently during drying.
- Another method: chop herbs, place in ice cube trays, fill with water, and freeze. Store the frozen cubes in the freezer for later use.|
