I must be on my 100th avocado seed that is not not growing I am getting pissed of with it and think all the avocados I am eating must be man made with dud seeds put in for effect. aaarrrrgggghhhhhhh
I'm pretty sure I've heard that these are hard as hell to germinate. Maybe give this a read if you haven't already: http://www.ehow.com/how_2205595_grow-avocado-pit.html
Maybe try and get some cuttings as well. Good luck!
