We have an avocado tree we started from a seed four years ago. It's over six foot tall now but still have it in a pot. We just stuck toothpicks in the seed and suspended it in a glass of water on the kitchen windowsill. This is the second time we've gotten one to grow. My mom used to try this too but never got a plant.
This is inspiring. I buy avocados almost every week, 2 for $1 at Groc. Outlet. They are small avocados.
Sometimes I get the huge ones at Costco if I need a whole bag of them. Maybe the larger ones would be better to grow??
Does your 6 foot tall one grow any avocados on it?
