Q.Avocado Trees
If you root an avocado seed from an avocado you buy at the grocery store, when the tree grows, will it have fruit on it? Or do you have to graft the tree? Or something else? If you use the tree as a house plant, how should you trim it to keep it from growing too tall for the house? What size flower pot should it be planted in?
