I have no idea if the tree is drafted or not.It started fruiting about a month ago.I picked one apple to see if it's ripe but it's not and the birds are already eating it.Some are even dropping on the ground.
Sorry - I meant grafted! Has another part of an apple tree been grafted to this one?
I would put netting over your apple tree. Hardware stores sell netting big enough to cover the tree for under $20 - and you will get to eat your apples. After I put netting over our raspberry canes, we actually got to eat some delicious raspberries and the birds got much less!
