growing fruit

I might not have a vege garden yet but things are growing well in the orchard which consists of:apple, plum, apricot, peach, nectarine, cranberry, guava, mandarin, pear, blueberry, blackberry, strawberry, tangerine, lemon, grape, olive, feijoa.
We don't do any spraying and most trees don't get watered much either but the lawn clippings are used for mulch around the base. Ocassionally they have a drink with some liquid pig poo.
Only problem is keeping away the possums and the birds.
