I don't know what you've tried but I've started several avocadoes by using toothpicks to suspend the pit halfway into a glass of water.

I've done that 3 or so times now and each time it just sits there and does nothing. Would be super cool though.

I raid the neighbors citrus trees (with permission) and also prickly pear cactus fruit to make fancier lemonade.

While I applaud your enthusiasm, this is a long term project as avocado trees take 10-15 years to mature and bear fruit.

I've done this, although in my cold climate it took months to throw out a root. Give it time.
