I actually managed to get a 3 foot tree growing from an avocado seed but we moved and I lost it. Gotta start over. Apparently though, from what I researched, growing a tree from an avocado won’t yield avocados the same way avocado farms do.
Rethink the Walls Vertical gardens aren't new, but living walls have gained newfound popularity. If you don't want to tend a garden on a wall, you can use an espaliered tree to soften a patio's border.
