I want to add, put in some nitrogen fixing trees or shrubs if you can, such as siberian
pea shrub (mine's only small, but very decorative) or laburnum with its beautiful yellow flowers; laburnum is toxic, but is a lovely tree and insects love it. There's also goumi, which I don't have personal
experience with, but it's both edible and N-fixing.
And there's bamboo which I'm obsessed with at the moment; you can eat the shoots, and its timber is very useful all over the garden; the birds adore it, and it's just lovely to look at and listen to.
I would also add plenty of insectory plants and flowers to help you with your pollination and to also add beauty; I would suggest buddleia (not edible, but a butterfly magnet!), calendula (edible), nasturtium (edible), daffodils (not edible, but attracts early bees to your early-flowering fruit trees), lupin (not edible, but N-fixing), borage (edible).
