Q: A guy on your radio show asked about growing softball-size onions. We planted Vidalia onions several years ago and they were a lot bigger than softballs!

A: I have no doubt your onions were big, but you likely started them from small “sets”: tiny bulbs that hadn’t started to grow. The radio caller had onions from last year’s garden that had sprouted and he wondered if they would continue to get larger. I advised that his onions might get a tiny bit bigger but he’d have better results starting with sets.
