I'm planning out the future orchard, as it will likely be the first improvement we make. I'm no tree expert though and I'm having a little trouble digging up suitable information on all the different varieties. I was hoping someone here knows a good bit about heirloom fruit trees and can steer me to the best varieties and nurseries. Let's start with apples. I'll be in zone 3b/4a, so I need something cold-hardy. We'll want a wide selection to cover all purposes, preferably several exceptional varieties each of which excels in one area, such as cider apples, pie apples, fresh eating and storage. But how on earth am I to choose! Just so far the list has Baldwin, Cortland, Liberty, Northern Spy, Red Gravenstein, Winthrop Greening, Yellow Transparent and Kingston Black Cider. Being as I still have to fit other fruit and nut trees into the orchard, can anyone give me more information about these varieties and which ones they would choose to cover all bases?
