Various Apple Trees are available.  They are about 6 years old and all have had apples on them in the past.  They are trained to have low growing branches so fruit will be easier to reach.  They are mostly on M111 rootstock. Most will have fruit on them this summer. They are a similar size to a 24 inch container.
