Plant blackberry bushes in a sunny position in any well drained soil. Incorporate plenty of well rotted manure or garden compost into the ground prior to planting. When growing blackberry plants, support the stems on a framework of wires stretched between sturdy 1.8m (6’) posts, or trained against a trellis or wall.
Water well for the first year until blackberry plants are fully established. Train the stems onto their supports as they grow. Cover the plants with netting to protect the crop from birds as blackberry fruits begin to develop. Blackberries can be harvested from July onwards. In autumn, prune the canes which have fruited over summer to ground level. Canes which have not fruited should be ‘tied in’ to their supports. In spring, while the ground is moist, apply a mulch of well rotted manure or garden compost to the base of the canes to improve moisture retention throughout the summer.
