I have a couple of places where I am growing onions at the allotment - some in raised beds with a mix of compost/manure/soil which are doing great, and some just straight in the ground which is sandy/loamy soil which aren't so big.
I noticed that there was one in a raised bed that was yellowing, so I pulled it up and found that it was rotting inside, so I threw it away and put it down as a 'bad apple'.
Today I have just found another, but this time one that is in the ground, I pulled it up and again found that it was slimy just above the roots.
Is this something to worry about? The onions in the bed in question are absolutely huge, and I certainly don't want to lose them to a disease.
