I have a problem with my grape vine. It is 6 years old and for the first two years did not fruit, third year a few grapes and 4th year a lot of grapes, 5th year only two bunches very small, this year two flower shoots, the first one died and the second one now looks pretty poor. The growth is vigourous and healthy. I am sure that I have pruned them correctly, I have fertilized them and watered them as and when required. I have no idea what grape it is except it is red. I live in Turkey on the coast near to Bodrum. Winters wet but very little if any frost, temperature can reach up to forty in the height of summer. Please any help very gratefully received. Jill
