Backyard Aquaponics
A place to discuss aquaponics

Well, I remember someone telling me a long time ago (in the 70's) that you could plant the end of the green onion with roots that you cut off and it will grow.

I never tried it, but I am trying something different. It may not work.

I took the end of an onion the Queen cut off of a green onion and gave me to put in the BSF Larva Harvester with other scraps. I took the end of the onion and quartered it into 4 pieces and planted all 4 pieces in my grow bed.

Does anybody think it will work, or did in kill it when I cut it up?

Hmmm... you might be lucky to get one or 2.
You seem to have picked the right timing

Depends on how long the bit is that you cut off: 12cm would work fine, but 1cm is, in my mind, very questionable. Quartering it would make it less likely, I think.

Note: this is all based on the fact that I've never seen one of our onion cut-offs grow.
