I occasionally have some avocado seeds taken from my gobbled down avocados. I stuck one in my toad tank and now it has a 3 inch sprout emanating from its top.
I wonder if I stuck some in the ground outside if they'd turn into trees without issue... or if they'd croak (that's Hillbilly Latin for die) as soon as the weather got too hot or too cold. I hear they work fine in nice weather from 65-85 Fahrenheit or so, which is what it is most of the year here... but occasionally it hits 105 in the Summer, and 18-20 in the winter, so I don't know what would happen. It's not like I have anything better to do with the seeds, (other than using them as cheap imitation ping pong balls), but if any of you have had success with Avocados, I'd like to hear it.
