Really, you know that some fruits or vegetables are not stored together and it is wrong if you do? For example, if you want avocados to last longer, never put them next to bananas. This is also true with other fruits, while there are some vegetables that need special storage in order to keep them fresh for more days.
See below:
Cucumbers are always stored in the refrigerator alone.
Apples are never stored with oranges. Place them in different places in the refrigerator.
It is also wrong to have potatoes in the same basket as onions. Always have them separately.

Tomatoes "hate" the fridge. It is better to have them out of it.
