My experience with the onion family is just chives. They all have beautiful lavendar seed tops. I'm trying to grow shallots this year. I planted the bulbs in March (zone 6b) and they are growing beautifully. They are all producing seeds on their top stalk. I don't want the seeds to fall into my limited vegetable gardening area. Would it hurt the plant and the crop if I cut the seed tops off?
On another note, I have 3 onions that I didn't harvest last year and they have grown enormously with, again, seed tops on the main stalk. If the seeds fall, won't onions grow from those seeds?
