Have you ever tried to grow an avocado? You know, with the toothpicks and the jar of water and the hope and dreams of your very own avocado tree? With avocados??? No, it's never worked for me either. So the other day I went to dump the compost and wha------? No less than 10 (TEN!) avocado trees growing. Right here in Ohio.
Sometimes when you're just not trying so hard, it happens.
