Tall hedge for privacy that bears fruit?
My neighbor needs a tall privacy hedge between her and her other neighbor. She asked me what she could plant that would provide privacy and fruit at the same time. I told her about the columnar fruit trees, but those would not provide much privacy during the winter, and they are pricey. She would like something tall and narrow so it doesn't take up the rest of her yard.
Any ideas? We live in zone 5, clay soil, late spring frosts.
