I just planted my vegetable garden but I'm really late for onions. My understanding is that I can plant onion seeds this late but will only get green onions this season. I'm assuming that part's correct.
My question is...if I plant from seeds now, what can I harvest for next season? Seeds or sets? I had been thinking sets, but as I'm reading various info this morning, I'm thinking it might be better to collect the seeds for planting next year? Or maybe it's just better to buy seeds over the winter and start then?
