Hi Sterelitza, Sorry about the delay in replying. For this year, once you see a bunch of grapes developing, count 3 leaves towards the growing tip and prune it there, just above the 3rd leaf, which will help the grapes to develop. It will keep sprouting more shoots from the junction of each of the 3 remaining leaves and stem, which you can pinch out as soon as you see them. The vine's energy will then go into the fruit instead of more leaves which it doesn't need. Next Winter, follow the vine from the root and cut every sideshoot off, leaving a short bit of it with 2 buds. What you are trying to achieve is one main vine, with lots of short side shoots. Each of these will grow next year and will be capable of producing one bunch of grapes. If it has already grown too high in the apple tree to prune, you could cut it back to a height you can reach, but only do that in mid-winter.
