I have had an everbearing red raspberry patch for many years, unknown variety given to me by a friend. The past few years the patch has declined dramatically, with fewer, smaller friable berries, shorter canes, not responding to modest fertilizing. The foliage looks normal. I am assuming from doing a little reading that this is a virus infection and I will have to replant.
Questions: How far away from this row will I need to put the new plants to prevent re-infection?
Is it possible to prevent reinfection?
My yellow Fall Gold everbearing rasberries are about 50' from the above red raspberry patch, what can I do to protect them (they seem normal so far)?
I will be converting a lawn area to raspberry rows and want to make some raised beds with borders - will treated wood be an issue with raspberries? Suggested alternatives?
Last, what varieties would you recommend for PA?
