how to kill raspberry virus?
I have 2 raspberry patches that have yielded poorly the last 2 years. I suspect I have one or more of the dreaded raspberry viruses and have already bought plants to start a new raspberrry patch in virgin soil away from the existing plantings.
Assuming I have a 3rd year of low yields my plan is to burn the plants and plant the existing raspberry beds with something new.
So .. what if anything should I do to kill any virus that might remain in the soil after removal of the affected raspberrry plants?
