When to harvest potato onions...

11 years ago

I planted potato onions last September. They did well all winter here in norhtern CT and have flowered but are still standing tall. I've harvested a few and they tend to be small, from large scallion to about the size of my thumb - should I leave them in and if so for how long? I was expecting some of these to be at least golf ball size or so.
