I break up avocado peel and toss it in my compost for extra aeration. Cynthia, I was told to break up/chop up avocado pits or they could grow. Avocado trees are so temperamental I just would rather not even try to deal with them yet. They grow well in our area, but fruiting is another matter. People will live no more than a few blocks apart, treat their avocado trees exactly the same way, with fertilizer, companion trees, watering, and climate, but one person's trees give an insane amount of fruit, and the other person's tree is beautiful, but gives nothing. My grandma had 3 trees for 15 yrs, never fruited, and when she gave them to someone who lives on the opposite side of the same town only 3 miles away, the things are now fruiting like fiends. I'll probably try my hand someday, but phooey! Not until I am ready, LOL!
