Disease or fungus or what on wild blackberries
I'm very new to gardening. I'm told I've got wild blackberries growing in the backyard at the edge of the woods. They looked fine until a few weeks ago when the leaves got spotty, turned brown and started dying. What is this? Should I do something about it?
Hi- although it's difficult to see individual leaves in your photo we think your plant is wineberry (based on the large number and color of the prickles) Wineberry photos:
The leaf edge burning symptom, random chlorotic spots, and relatively rapid decline of the entire plant suggests some type of pesticide spray (herbicide?) injury, rather than a plant disease or insect pest. It's possible that very wet or dry soil conditions could also be contributing to the symptoms. In any case, this is a highly invasive, non-native plant and should be removed.
