Boysonberries are vining brambles which are a cross between raspberries, blackberries and logonberries. They were first developed in the 1920s in the US, however Mapua is more recent NZ-bred variety. It is heavy producing and used for commercial cropping, but also great for home gardeners. Canes are vigorous and can reach up to 2m high and spread 1.5–2m wide. Large, tasty dark purple berries are produced on the second year canes. The canes/vines are thornless – what a blessing! And produce in time for Christmas – another blessing – bring out the pav! Cropping should continue through January, possibly into February. Deciduous.
11cm pot
Plant in a sunny spot unless you are in a super sunny region, in which case part-shade in the afternoon may be suitable. The soil should be free-draining and well-nourished. As with most berry plants, it’s important to keep up the watering through summer dry spells to ensure a good crop. The plants should ideally be spaced 150cm apart and trained along a trellis or wire for ease of maintenance.
The stems or canes go through a two year cycle. In the first year, a new stem, the ‘primocane’, reaches a height of 1.5 metres or more and produces leaves but not flowers. In late summer – early autumn, prune off 10cm of the terminal growth of the canes to help initiate the production of fruiting spurs the next year. In the second year, this cane is a known as a ‘floricane’, and the lateral buds open to produce flowering laterals. After these canes have fruited they should be pruned off right from the base, in autumn or winter. Also remove any dead, damaged and/or congested canes. All strong canes produced in spring and summer should be tied up, and thin, weak canes, or ones heading into your pathways should be pruned off.
Both blackberries and raspberries are high in nutritional and medicinal compounds, the likelihood is that boysenberries have inherited these traits, but i would refer you to the information on these other fruits.

Jo has a passion for growing herbs but is not a qualified herbalist and has no medical background.
We are lucky to have Patricia Beagle working here at times, who is qualified, and some of her advice does appear on these pages, but herbs act differently for different people and can interact with other medicines. We therefore always recommend that you consult with your own qualified health-care practitioner before using herbal products, particularly if you are pregnant, nursing or on any medications.
