Peach trees. Orange trees.
Last year I had a good crop of peaches. Nice and firm and full colour. But for some reason although the crop was looking good we did not get one peach that we could eat. The tree is 12 months old.They were too hard. Also, I have aa orange tree that the leaves are turning yellow and there is holes in the leaves. This tree is also a young tree. Any help would be appreciated. Keith Pull

New Zealand should be able to support citrus growth but may have not had a long enough cold period for your peaches. Some varieties require a certain number of hours below freezing to produce a crop, and during warmer years, may not produce.
Now As far as the holes go... This could be a number of things from insect to fungal damage. Here is more information:
