If you think you have a too small a garden to have an orchard - think again!
It is easy to grow dwarf varieties of fruit trees in good sized pots. I myself have an orchard in pots that consists of a manadrine tree, two dwarf apple trees, a miniature peach and orange (the tree is just miniature not the fruit.)
Growing fruit trees in pots is easy, all you need is a good sized pot and top quality potting mix. Good drainage is necessary and you can achieve this by placing some broken crocks into the bottom of your pot before adding the potting mix. Do not plant your tree deeper than it is in the pot you buy it in. You may need to add some support and occasionally feed with the appropriate food.
If your tree is new and young, it may take a couple of years to flower and fruit, then you will be able to enjoy your own organic fruit straight from your garden.
Go on, why not give it a go!
