hi, We live at about 1300 feet in, very windy, North Wales. when we first moved here I bought some apple trees from a local nursery, at the checkout the cashier said 'I know where you live, these wont grow there'..... I bought them anyway and have had decent harvests from them ever-since, where been here 14 years now. Shelter is key, we spent a lot of time planting trees to create shelter and are now able to grow most things..... we're a bit slower than lower down, but not massively so. raspberries and blackcurrants grow brilliantly up here too.
