Garlic rot.

I notice a couple (2 of 16) of my garlic plants are looking very sorry for themselves lately. Based on previous years if I lift them they will have a white / blue rot on them.

Is it likely to be white rot or simply just a bulb rotting ?

Other bulbs, 8" spacing look fine for now. I've had beans in this bed for the past 2 years before then it was grass. Garlic was from a proper supplier and not saved, planted tail end of last year.

I get that on occasion as well, an iffy bulb or two from a supplier that ends up rotting.

The rest look fine so I wouldn't worry about it.

I think it the odd bulb because if was a serious soil problem the other bulbs would be infected by now. I have seen this blue/white rot on bulbs such as daffs and tulips i have forgotten to plant.
