|Aren't these roots beautiful?|
I've been doing that with my onions and potato peels and things are coming along rather nicely.
Sprouting the onions turned out to be easier than I expected: all I had to do was to put the onion end into a cup half full of water with the bottom end down on a window sill. Every time I use an onion, that's where the bottom end ends up.
I change the water every other day. I'm going to allow the onion roots to continue to grow until the bulbs are ready for transplanting.
Yesterday I also started to plant my potato crop in a big metal half-tank. I used to compost scraps and bits of grass in the tank back in the day, which I never got to use in the garden.
So now I have very rich soil for the beginning of the potato tank. Wish me luck! I've never successfully grown potatoes.
