I have a Stark pear tree that I purchased in a pot at a nursery, that I planted in May three yrs ago. It only puts on about two inches of growth and just sits there the rest of the summer. I have a bare rooted pear tree that I planted the same time and it is growing like crazy. I treat them the same. They get light ,,everything the same. The tree that won't grow is a Moonglow. Anything I can do to get it growing? Or,,,just a crummy tree? Plant more pear trees I guess,.and hope you get a good one.
