How long after you plant an onion do you get more onions?

Question

I found an onion in my fridge that had started to sprout a couple of tubers, so i planted it outside and the stalks are now about 2 foot tall,so i was just wondering when I should expect to harvest for eating ?

Answer 1

plant one onion you get one onion your talking shallots

Answer 2

As you describe it it looks to me the onion is trying to follow its natural cycle of life:
....starts as a seed/it grows (we humans harvest it at its best, interfering in its cycle) then while in storage if in contact with humidity and light it will try to continue to grow. If planted in the soil you will find it will eventually give you an Allium type flower from which to harvest new seed. Like everything else it has its own cycle of life!
The sets of onions you buy to plant have carefully been selected at the stage of this cycle to maximise yield for harvest but if left on the ground it too will fulfil its course except that for commercial reasons most plants we now buy may have been genetically altered and while it produces great harvest they will not produce seeds (simplest best example to use would be the seedless grape)..this could cause some problem in parts of the so called third world where if grain is grown for food is OK but there will still be the need to find resources for the next sawing as the grain produced would be sterile (good for food but cannot germinate).....
I have gone a little off the track of your Q , but you get my meaning and concern for these practises. Don't you?

Answer 3

3 months

Answer 4

Heh. Onions are sensitive to daylength. Planting one in the fall is probably counterproductive. But hey, what have you got to lose?

Answer 5

three to four months.
