So I got this onion that has just sprouted in my fridge like 3 or 4 inches. I want to plant the darn thing. Anyone got any ideas of the best way to do it.Like do I plant the whole onion or cut off the sprout then plant it.Before I plant it, cause I got about another month before I can put stuff in the ground, should I put it in a bowl of water in the window, which is what I did or what?I like gardening, it is fun to watch things grow. I've been doing it for a few years. I try to plant different things and some the same. I can't wait till it is time to plant stuff.

You need to plant the whole thing, with the onion just below the surface and the sprout above. You could do it in water if you wish, but plain water supplies no nutrients and should only be temporary. You can plant it in soil in a pot and keep it indoors by a window until it is warm enough outside.

Onions are biennial. That is it takes two years for them to go through the entire life process and form seeds. The onion you have, if it is of any size, is already a year old and will produce seeds rather than an edible onion. You sometimes see onions "sets", baby onions if you will, that have had their first year growing process interrupted. Replants those, with proper water and fertilizer, will yield an edible onion.
Your best bet is to just use the onion in cooking before it sprouts any more.

Good advice.. It's been over 30 years since we grew onions at our ranch as a kid. I was thinking, how can you grow an onion from an onion? You reminded me that we planted tiny little seeds. If I remember corrctly, they were like tiny black poppy seeds.
