Do Primocanes Bear Fruit The 2nd Year And Should I Remove Them After The 2nd Year?

Question

The article by Mary ellen ellis was unclear. I got starts for a thornless blackberry from a friend and was told that only 2nd year canes would bear fruit! SO I have pruned the last two seasons all old ( fruit bearing)canes by the end of the fall! I have not seen any production of the new canes in the fall? This years growth seems less vigourous then the previous year when new canes grew up to the gutters! So does only one type of cane grow each year,?, I have shared canes/starts with several friends last year but have not gotten any feedback. I need to go look at new growth from starts I shared last year and this year. I purchased some (3)Heritage Raspberries last year and then reordered 3 more when only one plant survived over the winter. So both types of canes produce fruit but one may grow bigge and not fruit until the 2nd year, but the 2nd will have more fruit over 2 seasons? ,

Answer 1

They will fruit every two years, and benefit from pruning out canes that have already fruited. The old cane that has fruited will not bear again. These two articles are a little more clear (although one has quite a bit of information that you won't need.)
