My raspberries got off to a good start this spring with growth on last year's canes and lots of new canes poking up from the soil. But the spider mites came back too and they've pretty much destroyed most of the leaves. Newer growth appears to be ok for now but eventually the mites will move up there too. I tried to spray them into oblivion a few times with the last of my neem oil and that might have slowed their progress but the damage was done. I've considered some insecticidal soap but I think it's too late.
