My grandmother threw 3 avocado seed things into her compost and they all rooted. She put them into pots and gave them to me because I was unsuccessful at rooting some in water. It's possible, my sister did it, but It has never worked for me. Anyway, Of those three I managed to keep one alive. It's not much taller than last year. It had a bit of drama over christmas... leaving it with only a few sections of leaves. I didn't take any photos of that.
