All of the Apples and Pears we use are from local orchards in somerset, we have 5 of our own orchards which is enough for about 70-80% of what we need. all the orchards we have are un-sprayed ,not fertilised and generally have sheep in to keep the grass short.
A standard perry pear orchard planted in 2000, the trees grow much larger than the apple trees but take nearly 50 years to fully grow.
A couple of pictures on the blossom from the apple orchards.
