Hi Ya’ll I’ve been lerking the shadows for a bit and have looked at lots of conversations on here. I became obsessed with apple trees and grafting about 2 years ago. Luckily I have family land & they have let me install an orchard that in the end will be around 100 trees, it’ll be mostly apple with a single line of pears for fun.
I don’t have any particular rhyme or reason for what varieties i’ve decided to use other than I’m having a ton of fun. They are all extremely young non fruiting trees at this point. I can say that so far my personal favorite apple is a Cortland however i’ve yet to try 99% of the apple varieties I’m growing, so its going to be such a new experience once these start to fruit. 
My current growing list so far include (* means I have tasted this variety)
