Possible Outdoor Apricots and Peaches fruiting 2017

I have been asked many times which are the best fruiting varieties of Apricots and Peaches for the UK climate. Well this year is the first year I have started logging fruit set, with the prediction of a harvest.

Our situation as to where these are grown, is on a North facing slope, made up from heavy clay in the heart of the Midlands, UK. Our temperature zone is 8a that being -9.5 deg C to -12.2 deg C

Many of the trees are quite young and not have settled down into a production rhythm.
