鲁本 (Reuben) 黑莓品种

My Reuben plant in one-year mode (bearing on primocanes only). I cut off all stems in late fall.
The main disadvantages - very prickly blackberry variety, low yield. Advantages - Reuben blooms and bears fruit until first frost.

Reuben Blackberry: A New Amazing Vatiety.
No Dig Organic Allotment Kitchen Garden And Fruit Orchard
 

We have 2 Reuben plants, now in their second year. We live in North Yorkshire and the plants are at the top end of our South-facing garden, protected from the north by our greenhouses.
Early this year I cut down the first year's canes. Growth of new canes, 5 on each plant has been very vigorous, with lots of flowers. Fruit set well, but late, and is now only ripening in mid October. Fortunately the Autumn has been mild so far so we are gathering a little fruit, (HUGE, sweet and flavourful) but most is still green and will inevitably be cut off by the first sharp frost.
I did double dig the narrow, long beds, incorporating a lot of well rooted compost and manure into the clay soil. In future years I think I will drop fleece screens from the eaves of the greenhouses to extend the ripening period.

Low-height moderately vigorous bushes. Two-season harvesting. Berries are not big or medium size, closer to small. Taste is sweet and acid (50 on 50). Aroma is typical. Really gives fruit up to late fall. My plant is similar to Prime-Ark 45, but fruit are smaller. New replacement canes can be very thorny. Some drupelets often were red, even other are ripened.
