There’s 2 canes looped around from one plant on the trellis. We had a long hot summer and I gave the plant all the water and fertilizer it could want. The canes just seemed to keep growing and growing, they’re probably 15-16 feet long. Next year should be even better since the primo canes coming up now are even thicker (5/8"?) than those from last season.
Here in the Fraser Valley Black berries grow wild and thrive so it makes sense that it would do good in this soil and climate.
