Onions in storage can rot if they are kept too cold, or too hot. They need cool temperatures (ideally 40-50°F) in order to store for the maximum amount of time. Avoid storing any onions with signs of botrytis or mushy rot at the point of harvest as these can infect entire crops in storage.
Why are my onions rotting so quickly?
The lack of sunlight reduces changes in temperature and humidity, two factors that can cause them to go bad faster. It’s best to store regular onions in a cool, dry, dark and well-ventilated room. Places that may provide these conditions include a cellar, pantry, basement or garage.
How do you keep onions from rotting?
Managing Soft Rot in Onions
- Avoid overwatering your onion plants, especially when it is hot out.
- Make sure your onions are planted in ground that drains well and that you give them space for airflow and to dry out between waterings.
- Avoid damage to the entire plant while the bulb is developing.
Why are my onions going Mouldy?
Onion downy mildew is caused by the fungus-like (Oomycete) organism Peronospora destructor, which infects first the leaves and later bulbs of onions and shallots in mild, humid weather in late spring and summer. Some perennial onions such as chives may also be infected. It is worse in cool wet seasons and in wet areas.
What happens if you overwater onions?
Overwatered onions quickly develop yellow foliage. The tops will soon fall over if the plants keep getting too much water. The onion bulb and roots will then begin to rot, unless the plant can fully dry out. Once the rot sets in, you cannot salvage your onion plants.
Why do onions turn to mush?
If they’re too thick, the outsides of the onions might get mushy before the middle is cooked through; if they’re too thin, they might burn too easily or cook before they have attained the right flavor.
How often do onions need to be watered?
Ideal onion water needs are to irrigate to a depth of an inch (2.5 cm.) once a week rather than a light sprinkling each day. If you are watering onions with a hose or sprinkler, water in the morning rather than during the heat of the day, which will just end up being evaporated. Overhead watering can spell trouble.
Is it safe to cut mold off an onion?

You will want to water occasionally but thoroughly, applying about one inch of water each time. We recommend using the “knuckle rule” to tell when it’s time to water. Stick your finger into the ground near the plants; if you can’t feel moisture up to your first knuckle, it’s time to water.
Why onions should not be refrigerated?
In case of refrigerating peeled onions, the moisture and cold temperature inside the fridge can make them lose their crunch and turn soggy, which makes way for pathogens to develop and this reduces the nutrient level and leads to bacterial growth.
Should onions be refrigerated?
