Description

The Japanese blackberry is distinguished by its red-streaked, sticky canes and glossy orange‑red fruit that taste like small raspberries. It is a decorative shrub that climbs well on fences or trellises. In some areas it can become invasive, so give it a limited location.

Care instructions

Plant the blackberry in a sunny to semi‑shaded spot in humus-rich soil and tie the long canes to the trellis. It bears on two‑year‑old wood, prune away spent canes after harvest. Keep the growth in check by removing suckers in the hedge and harvest the sweet berries from July onward.
