Thank You for the tips. Last year I did put a fan on them but ended up with the same results and I don’t recall any rain or watering being done towards the end of their season. Humidity may be an issue as you mentioned because I did dry them in the garage which, incidentally, is air conditioned although I didn’t think to use it for onion drying. Odd though, to me anyway, that my garlic does well being dried the same way as I’ve done the onions. BTW, do you dry your onions in the sun or shade? I read conflicting recommendations on this.When you have rot between the layers that may be the long green tops broke and water from irrigation or rain got down into the plant. I've trimmed my onions down before out in the garden to increase bulb growth but you need to make sure no moisture gets in the open tops before the plant seals itself at thep base. Or the humidity is high where you cure them at. A fan circulating where you are drying them in say a garage. I hope you try again and are successful!
