Q.Orange dust on our wild blackberry bushes.
We have wild blackberry bushes in Gaylord, mi. We had this problem 8 years ago when we first moved here and I don’t remember how we dealt with it. We have not had cool weather just the opposite very hot and muggy. The worst ones are outside of the garden area but there is one inside. Should I carefully cut it and remove it? They are a bugger to pull out and I am afraid of spreading the disease. We started a garden year’s ago that did not do well so when the blackberry bushes started taking over I thought cool that will be our backyard patch. This should be the best year ever and I don’t want to loose it.

This would be blackberry rust. It is only treatable, and will not be cured. This article will help: https://www.gardeningknowhow.com/edible/fruits/blackberries/blackberry-orange-rust-treatment.htm
