We have been wondering whether, when, and how to prune our raspberries.
We want to ensure that our patch remains healthy and will produce next year. We also want to cull the herd a little as they are running a little out of control. After a little research, here’s what I found.
First thing, there are two kinds of canes–the first year canes, that don’t produce fruit, and the second year canes. These are the producers. I guess there are a couple other kinds as well–third year and beyond–these I guess just need to be pruned off, and dead ones that definitely need to be removed.
For the living, you need to prune in late winter or early spring.
So you have to identify the new and old ones. I did not find much information as to how to make this distinction other than somehow remembering which produced fruit and which did not. But, this says to look for ones with “grayish peeling bark” Cutting the canes involves trimming them down to about four inches from the ground.
Then you need to trim back the suckers. These are smaller canes that seem to be a result of an attempt by the plants to spread.
Other things we need to do:
- tie the canes up to some string, or maybe to the fence
- try to limit the number of plants and get them into some kind of orderly row
Pruning seems to be important and should allow for new plants to come up. Its also a good way to prevent disease.
