I created a raised bed about 2 years ago , it 4 blocks high and 4 feet wide and 25 feet long and has at least 18 to 20 inches of good top soil in it.

I grow a variety of veg but for the past 2 years onions both ordinary and red and shallots have not kept for more than a month or 2 after lifting them in August.

They appear to start rotting from the neck down.

Can anyone give me a reason why this should occur

Regards

Matt

could be neck rot It is caused by a fungus which usually infects mature plants through the neck tissues or through wounds in the bulbs. The disease is most common on the bulbs after harvesting,a dense grey mold develops between the onion scales. Sometimes hard, black bodies (sclerotia) will form around the neck. Usually soft-rot bacteria invade causing the bulb to break down into a soft mass; often accompanied with a foul sulfur odor.
