Hi, first of all I want to apologize for any grammatical errors, but I'm Italian and I can not speak English very well. But, returning to the raspberries: I have two plants of raspberries in a large container filled with good potting soil. I do not water them often, only when the soil is not moist. nevertheless, a plant began making of dry and brown leaves. what can it be ? which is the reason for this? I have already seen this in other websites and forums but no one was able to give an answer.
Thank you so much
