Young apple tree pruning
Hello all, my friend has a young apple tree (2yr old I think from memory and about 4ft tall). We need to know how to prune it this Winter but although the RHS site says reduce main branches by a third and leave any young laterals completely alone, my RHS encyclopedia (20 yrs old!) says to reduce laterals. I'm really confused. The tree only has about 4 or 5 'branches' coming from the main stem (each are only about 18inches long) with each branch having some smaller branches growing off them (are these the young laterals?). I know to remove the three d's and crossing or inward facing wood but after that we're a bit stumped. Any help would be appreciated. Many thanks.
