Supposedly when harvesting onions, you are supposed to pull them and
leave them on the soil for a while. I can understand the need to ensure
that they are fully dry befors storing, but why leave them on possibly
damp, vernin infested soil?

I the past, I always laid them on an ols sheet on the patio, and moved
them into the garage or greenhouse overnight. Never has an problems
doing this, just curious as to the formal method.
