What's causing this distortion?
Blackberry psyllid? I just cut the old cane that I had tip rooted (new shoot doing fine) that CAES said had spur blight. While inspecting the other canes I found 1 new (but very thick) primocane in another roow that had twisted all around. The canes there are pretty thick. Leaves are distorted and dark green.
CAES mentioned the portion of dead cane I'd brought in had scale - could this cause this deformed growth? What's best to do - cut the cane off where it starts to twist, or cut it off at the soil line?
If this is some sort of pest (I know JBs are coming out, starting to chew on the leaves, might also have aphids) what's a good organic solution? I really don't want to use Pyganic b/c it contains rotenone and the rows are right near the house.
