p.98 Bush fruit
There are several types of bush fruit, all of which will do well in containers. You can choose from brambles (Rosaceae family), such as raspberries and blackberries, or currants and gooseberries (Grossulariaceae family).
You will need to provide a suitable support framework for raspberries and blackberries , both of which are best grown against a sunny wall. Use a simple trellis system of posts and wires. The greatest yield of fruit will be obtained if you trian the new canes horizontally along the wires, tying them in with string or twist ties.
