I have a hobby of growing Avocado Pears from seed , they make nice house plants & my current one is 3 ft high. They do take a long time to germinate, but it's fun to do.I currently have 3 on the go, small but ok, I water sparingly from the bottom of the pot as I believe they don't like to be to wet.
I am an avid watcher of G W , but not a 'keen' gardener, but it's a great interest to watch. Continued success Les Kerr Derby
