Help w/ expirement: Get onion to flower for seeds in 1 season
So - my fun project for this year that I need help with is to grow some onions from seed (which were started last week indoors)... grow large enough to harvest, try to make them go dormant for 2-4 weeks, replant and get them to bolt to produce seeds.
Winters are long here, and I have trouble getting onions to overwinter for spring planting...strictly for producing seeds.
1) How large does my bulb have to be before I harvest?
2) I am guessing the quickest way to make this go dormant is a couple weeks in the fridge? Other ideas?
3) Is there a good way to "re-awaken" the onion to start the bolting process?
Last year, I was able to get some onions to bolt indoors in september... and they threw up 4-6 shoots over a couple month period...but never the big bolt with the seedhead.
I would love suggestions to grow a large enough onion and get it to bolt in the same year!
