Keep things like garlic and onions in ventilated bags
Don’t store onions and garlic in the fridge. Instead, store them in a cool, dry, well-ventilated space. Make sure also to store them away from potatoes, as onions will cause the potatoes to rot! Onions and garlic have a very dry outer layer that protects them.
Storing them in the fridge, which is cold and lacks air circulation, is a surefire way to end up with soft, moldy onions. Paper bags provide a perfect environment for onions and garlic, allowing them to breathe while keeping them out of direct light.
