Crumpled blackberry leaves
I posted this last year, but I never really got the answer that I was looking for. I get this both on my Chesters and also my Triple Crowns. I am familiar with aphids as they appear on my apple trees, but I just checked the leaves again, and I'm not seeing any signs of them. Any idea what this is? Thanks, -Glenn
Nice new growth:
