When I pruned my little apple tree in winter I stuck the prunings in the ground (don't ask me why!). Now I have noticed that they are leafing up, which presumably means that they have rooted. This leads me to my question, which is, will these go on to produce little apple trees? Can I train them into cordons or similar, or will I be wasting my time. I appreciate that apples are normally grown on a different rootstock, so maybe they won't be vigorous enough. The variety is Worcester Permain, by the way. Any advice will be very welcome as I am a bit of a novice when it comes to fruit.
