Lovely strong and healthy thornless blackberry plants. About 40-60cm professionally tied up with canes, in a deep 2 litre sized pot.
Domestic Blackberries are more productive and better behaved than their wild relatives, and can be trained in a variety of ways – they will happily ramble over arches and pergolas, or up a trellis or wall. If you are short on space there are compact, thornless types of blackberry that will grow perfectly well in containers.
Blackberries can tolerate light shade, but they will be more productive in a sunny, sheltered site. They prefer moisture-retentive, but free-draining soil. If you have chalky, sandy, or heavy clay soil, improve with plenty of bulky organic matter (two bucketfuls per sq m) before planting.
They are usually bought as container-grown plants. A single plant can be incredibly productive, but if you plant more make sure they have plenty of room. Spacing depends on the vigour of the cultivar, ranging from 2.5m (8ft) to 4.5m (13ft) apart. When planting, cover the rootball with about 8cm (3in) of soil.
