Established red raspberries

Raspberry    Pennsylvania

I have a 25 foot row of ever bearing raspberries and a row of summer bearing raspberries. The rows are parallel to one another, and about 5 feet apart. They were planted 6 years ago. Last year, I noticed the centers of the rows looking rather sparse. Now, it is clear that about one third of the center of each row is gone! Can I simply plant new plants in this empty space? Is there a way to propagate new plants from what is still there and growing? Also, the winter was very harsh. Could the plants have been killed by extreme weather?

Guillermo commented,
When you say that the center has become sparse, do you mean the whole row in an even way (as if now you would have two rows separated from the initial row)? if that's the case, I think the solution (and the cause) is in the prunning technique used.
over 5 years ago.


Do you know the actual variety? Then you can also know how cold they can be and still be healthy. Though most raspberries are hardy in cold, some even holding up well as low as negative twenty degrees Fahrenheit.
The gaps may just be from allowing the rows to spread? I know that raspberries need to be pruned to help regulate growth and production, and some need to be completely pruned down. This is to help air flow, sun, and nutrients get to the plants, helps prevent diseases, and makes it easier to pick.
I've only worked with Joan Js (fall bearer) and Canbys (summer bearers). For Canbys we prune out the two year old, dead, and diseased canes to make room for healthy fruit bearing canes and tie up the remaining canes for added support. You can add more plants or propagate from existing canes. Though you don't want to over crowd your plants. It may not be a good idea to plant new plants in if it will over crowd your existing plants. Joan Js we prune all canes to an inch in right before spring, tying them up as they grow new canes. We remove the cut canes to prevent pests and diseases from occurring.
How wide are your rows? Keeping your rows within a two feet width also helps to prevent diseases and makes it easier to pick the berries.
