cross pollination of apple trees
I have two dwarf apple trees which have crossed over. One variety is call greensleaves and has not fruited for 3 years until last year. The other tree is more like a braeburn, which I prefer. Now both varieties are growing on both trees. My problem is that the greensleaves variety has so much mildew on it that it affects the fruit. I do give the trees a winter wash but still get the mildew on the greensleaves but not on the braeburn variety. If I cut down the offending tree would the remaining tree revert to it's original variety? Help!
