I am trying to grow an onion plant from an onion bulb after learning vegetative propagation.
I do in this way:
- Phase 1: Put the onion on a piece of wet tissue, wait for it to grow a shoot with a leaf.
- Phase 2: Put the prepared onion into a box with soil.
However, I never manage to get the onion to grow a leaf. Grey rot appears on the onion after a few days and flies soon dance around it.
Any suggestion of how to not get rot on the onion or any method for the onion to grow a new leaf?
