Attach the main canes to the wire with a clip or a slightly loose zip or twist tie. Black and Purple raspberries break buds from their crown or base and send out few, if any, suckers.
How do you transplant black raspberries?
Raspberries spread by roots and the new plants that pop up are often called ‘suckers’. You can transplant them. The key to success is, find a sucker at least a foot or two from the mother plant. Mark the halfway point between the sucker and the mother plant, and dig there first, cutting that section of root in two.

Individual canes grow vegetatively the first year, produce fruit the second year, and then die. You can cut second-year canes back to the ground after you’ve harvested all the fruit from it; each cane only produces fruit once.
Can black raspberries grow in shade?
Above: Black raspberries are relatively tolerant of shade, making them a useful fruit for gardens or terraces with fluctuating sun. I have grown them in as little as four hours of direct sun at the height of summer (seen here on our Harlem terrace).
What happens if you don’t prune raspberries?
The suckering nature of raspberry plants means that if left unpruned they become very congested, produce small fruits, and outgrow their allocated space. Also, the fruited stems will gradually become weaker each year and eventually die.
Are coffee grounds good for raspberry plants?
