Apples need cool temperatures to retain their freshness when stored for a long time. While cold temperatures alone are enough to keep apples fresh for weeks, with a little extra care, you can store apples for up to several months.
Steps
Short term storage

Choose to preserve fresh apples. [1] X Research Source Check the number of apples you have selected and separate bruised or soft ones from those that are still fresh. A bruised apple can actually spoil the others if left together, because apples release large amounts of ethylene gas when crushed. Therefore, you should not store crushed apples with fresh apples.

Arrange the crushed apples on the dining table. When left in a basket at room temperature, these apples can stay fresh for about 2 days. This is only a short period of time, of course, but crushed apples should be eaten immediately no matter how you store them, as partially crushed apples will rot faster.
- If the apple cannot be eaten because it is too crushed, you should throw it in the trash or if you live in a rural area and have a large garden, you can leave it out in the garden for other animals to eat. Even if there are no animals to eat, when apples spoil, they will be a food source for many insects and other creatures living in the soil.

Place fresh apples in the fridge. [2] X Research Source Apples will stay fresh for a long time when stored at cold temperatures. Most modern refrigerators have a fruit storage compartment or a cooler; If your refrigerator has this type of compartment, store the apples there. If you don’t have one, you can put the apples in an uncovered plastic container and place them deep inside the refrigerator, where temperatures are usually coldest.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/dc/Store-Apples-Step-4-Version-3.jpg/v4-728px-Store-Apples-Step-4- Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/dc/Store-Apples-Step-4-Version-3.jpg/v4-728px-Store- Apples-Step-4-Version-3.jpg”,”smallWidth”:460,”smallHeight”:306,”bigWidth”:728,”bigHeight”:484,”licensing”:”<div class=”mw-parser -output”></div>”}
Cover the apples with damp paper towels when they are refrigerated. In addition to cold temperatures, apples also need a little extra moisture to stay fresh. Place a damp paper towel over the apples to provide enough moisture, but if you’re covering the apples with wet paper towels, make sure you don’t leave them in an airtight container or drawer.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/77/Store-Apples-Step-5-Version-3.jpg/v4-728px-Store-Apples-Step-5- Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/77/Store-Apples-Step-5-Version-3.jpg/v4-728px-Store- Apples-Step-5-Version-3.jpg”,”smallWidth”:460,”smallHeight”:306,”bigWidth”:728,”bigHeight”:484,”licensing”:”<div class=”mw-parser -output”></div>”}
Monitor temperature when possible. If you have a temperature control system for the cooler, you should set the temperature between -1°C and 2°C. This is the ideal temperature to store apples. Storing apples in colder conditions will cause the cells to burst, making the apples soft and inedible; while storing apples in warmer conditions at 12°C can make apples ripen twice as fast.
- If there is no thermostat system that allows you to control the temperature numerically, but has a basic knob that allows you to make the refrigerator or freezer cooler or warmer, place a thermometer in the drawer and adjust the temperature. Adjust the knob until the thermometer shows a number in the appropriate temperature range.

Apple tracking. Stored this way, apples will stay fresh for about 3 weeks.
Long-term storage

Preserving apples to keep for a long time. Sour, thick-skinned apples such as Jonathans, Rome, Melrose, Fuji, and Granny Smiths are the best choices. Sweet, thin-skinned apples like Red Delicious or Gpden Delicious often don’t give the desired results.
- Also, you need to make sure the apples are still fresh. Apples with soft spots or bruises produce a lot of ethylene gas, which causes nearby apples to spoil faster than normal and interferes with your apple preservation efforts.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/4/4b/Store-Apples-Step-8-Version-3.jpg/v4-728px-Store-Apples-Step-8- Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/4/4b/Store-Apples-Step-8-Version-3.jpg/v4-728px-Store- Apples-Step-8-Version-3.jpg”,”smallWidth”:460,”smallHeight”:306,”bigWidth”:728,”bigHeight”:484,”licensing”:”<div class=”mw-parser -output”></div>”}
Wrap each apple. [3] X Research Source Even fresh apples produce some ethylene gas; Therefore, apples that touch each other during storage usually spoil faster. In addition, if an apple rots while in storage, it can spread to nearby apples, causing all of them to spoil faster. Wrap each apple individually to prevent damage from touching apples.
- Tear a newspaper page in half and arrange the quarters in a pile. Choose paper that only has black ink because colored ink contains toxic heavy metals.
- Place an apple on top of a stack of newspapers. Take the top sheet of paper to wrap the apple, gently fold the corners to seal the apple. However, do not fold the paper too closely as you will tear the paper. The goal of this step is to keep the apples from touching each other, not to block the air around the apples.
- Continue wrapping each apple in newspaper until you run out of apples.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/7a/Store-Apples-Step-9-Version-3.jpg/v4-728px-Store-Apples-Step-9- Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/7a/Store-Apples-Step-9-Version-3.jpg/v4-728px-Store- Apples-Step-9-Version-3.jpg”,”smallWidth”:460,”smallHeight”:306,”bigWidth”:728,”bigHeight”:484,”licensing”:”<div class=”mw-parser -output”></div>”}
Seal wooden crates or cartons. [4] X Research Source Apple containers do not have to be completely sealed, as you will still need to allow air to circulate around the apples during storage, but the amount of air should be limited. Sealing the bin also helps regulate the temperature of the apples and the amount of air in circulation. Use straw or plastic liner with small holes to line it around the crate.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/1c/Store-Apples-Step-10-Version-3.jpg/v4-728px-Store-Apples-Step-10- Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/1c/Store-Apples-Step-10-Version-3.jpg/v4-728px-Store- Apples-Step-10-Version-3.jpg”,”smallWidth”:460,”smallHeight”:318,”bigWidth”:728,”bigHeight”:503,”licensing”:”<div class=”mw-parser -output”></div>”}
Place apples in a sealed container. Stack the apples side by side, making sure the newspaper doesn’t peel off and the skins of the apples don’t touch each other.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/9/9f/Store-Apples-Step-11-Version-3.jpg/v4-728px-Store-Apples-Step-11- Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/9/9f/Store-Apples-Step-11-Version-3.jpg/v4-728px-Store- Apples-Step-11-Version-3.jpg”,”smallWidth”:460,”smallHeight”:306,”bigWidth”:728,”bigHeight”:484,”licensing”:”<div class=”mw-parser -output”></div>”}
Store apples in a cool place. Agricultural storage is often used to preserve apples, but an air-conditioned room or somewhere in the house with a cool temperature is also effective. However, the average temperature for storing apples shouldn’t be below freezing, as the freezing process will rupture the apple’s cells, leaving them soft when thawed.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/66/Store-Apples-Step-12-Version-3.jpg/v4-728px-Store-Apples-Step-12- Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/66/Store-Apples-Step-12-Version-3.jpg/v4-728px-Store- Apples-Step-12-Version-3.jpg”,”smallWidth”:460,”smallHeight”:305,”bigWidth”:728,”bigHeight”:482,”licensing”:”<div class=”mw-parser -output”></div>”}
Do not store apples near potatoes. Cooked potatoes will produce gas, and this gas can cause apples to spoil faster. You can also put these two crops in the same room or storage area, but don’t put them next to each other.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/be/Store-Apples-Step-13-Version-3.jpg/v4-728px-Store-Apples-Step-13- Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/be/Store-Apples-Step-13-Version-3.jpg/v4-728px-Store- Apples-Step-13-Version-3.jpg”,”smallWidth”:460,”smallHeight”:313,”bigWidth”:728,”bigHeight”:495,”licensing”:”<div class=”mw-parser -output”></div>”}
Check the apple after a few months. Stored this way, apples can stay fresh for several months, but will begin to spoil soon after.
