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.
Get your seedlings off to a good start with their very own little greenhouse! The bottom part of a plastic soda bottle makes for the perfect little dome to cover your little pots with. This would be a fun project to get the kids involved with.
