Onion neck rot is a disease of onions and shallots caused by the fungus Botrytis allii. Plants infected by the fungus usually appear perfectly healthy whilst the crop is growing. Symptoms are not usually seen on the bulbs until they have been in store for several weeks.

How do you keep onions from rotting?
Managing Soft Rot in Onions
- Avoid overwatering your onion plants, especially when it is hot out.

Farmers call this disorder “slippery skin,” so named because the inner part of the onion bulb can be easily slipped out by squeezing the bulb near its base. This problem is caused by a fungus or bacterium entering the onion bulb through the neck of the plant.

How do you protect shallots?
Seal them up with saran wrap or an airtight container. Fresh shallots will be edible up to 10 days when stored properly. However, if you prep and dry them, then wrap them in a mesh bag or mason jar, they can be stored for up to 9 months. This is what you do if you want to plant them again next year.
What happens if you overwater onions?

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.

They should be grown in full sun, but will tolerate partial shade. Shallots are soil tolerant growing well where the pH is between 5.0 and 7.0. It is always a good idea to have garden soil tested every few years to determine what if any amendments it might need.
How many shallots do you get from one plant?
Each seed will only produce one shallot bulb, so multi-seeded modules are a good way to produce a clump of bulbs. Harden off indoor-sown plants in spring, to acclimatise them to outdoor conditions, before transplanting into the ground.
Do shallots need to be cured?
Shallots can be eaten right from the garden without curing, but the curing process will enable the bulbs to keep better in storage and may also help to control the spread of diseases.
How should shallots be stored?
After the shallots have been cured, cut off the dry foliage, place the bulbs in a mesh bag and store the shallots in a cool (32 to 40 F), dry (60 to 70 percent relative humidity) location. When properly cured and stored, shallots can be successfully stored for six months or longer.
Do shallots multiply?
Shallots, sometimes referred to as potato onions, reproduce by forming a cluster of small bulbs instead of one large bulb. These multiplier onions are a cool-season perennial but are typically grown as annuals in the summer garden.
Should I water onions every day?
Onions need a lot of water, but the soil should never get soggy. 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.

What does baking soda do to onions?
When you add baking soda during cooking it changes the pH which increases the Maillard reaction causing the onions to brown more quickly. The higher pH also causes the onions to soften more quickly, which we cover below when we discuss the texture.
What does vinegar do to onions?
Then you just have to wait long enough for the vinegar to do its job, rinsing away the harsh sulfurous compounds, softening the onion, and giving it a pleasantly tart pop of flavor. If you use red wine vinegar, my personal favorite, the onions also turn an amazing hot-pink color.
