Spring isn't here yet but I'm gonna start an avocado seed. They are free. All you have to go do is go to www.wegmans.com and buy an avocado.
avacados
They are far larger than most vegetable seeds.
All you need is a bowl, a seed and some skewers
use the skewers to support the seed so the bottom soaks in water until it sprouts.
I used a clear bowl so I could see what is going on.
after 24 hours not much as happened....
