First time growing Green onions :question

tomatodog(zone 10 So. FL.)March 21, 2013

I bought some onion sets and planted them they gro well and I love the green onion tops for my baked potatoes. I planted so many though that there are too many to eat, can I make them grow into larger onions by folding over the tops? Or do I need another variety or am I supposed to do something with tops of all varieties?

If the onions are short-day onions (likely if they are sold in FL) and if you thin them to at least 3 inches apart, they may bulb for you. That's what they are supposed to do. You don't need to do anything to the tops. When the onions are finished growing, the tops will fall over.

If you bought sets they are probably a bulbing variety of onion. You would need to thin them and let them form bulbs. But they might not do so at your latitude, especially if they are a "long-day" variety.

If they are allium cepa, they may bulb. But mostly what are sold as green onions in supermarkets (aka allium fistulosum, Japanese bunching onions, negi or welsh onions) are bunching onions, and will not bulb or only very slightly. If they are allium fistulosum, they can be grown as cut & come again perennials.

Here is a link that might be useful: http://en.wikipedia.org/wiki/Japanese_bunching_onion
