Apples haven't lost their leaves yet.
So it's almost January and my apple trees haven't lost their leaves. My anna apple tree's leaves are yellowing and I believe it is because it is beginning to lose them, but my Fuji apple has shown no signs of any change (In fact, it's kinda looked the exact same for the last 6 months... no growth past July pretty much). Last year Anna lost hardly any of her leaves.
What should I do about this? What about pruning?
