Fruit trees come in versatile sizes. We have trees to fit virtually any size plot. They begin as step over trees only a foot or so tall, then Espalier and Fan Trained Trees that spread out and Cordons that grow quite narrow, up against a wall. We have fruit on rootstock from 5ft to 15ft.
It’s no harder to plant a fruit bush than a basic garden shrub. A little farm yard manure and Sulphate of Potash (feed rich in Potassium) annually will help them produce successfully.
Red Currants, Black Currants and Gooseberries are lovely to sprinkle on summer deserts, straight from the garden. Protect them from the birds with a net, and you should get to enjoy them. Raspberries planted as canes, may need replacing every few years, but they are well worth the effort. Blueberries like lime free soil so they are ideal to grow in pots. Strawberries look fabulous on the patio, why not plant them in traditional strawberry planters. My top tip would have to be, plant plenty of the same variety for a reasonable crop.
