|Notice the black canes on the left and the healthy green ones on the right. What is going on?|
My sense is that I overwatered these guys and created a fungal disease. Canker?
Here is where you all might have something to say.......
I trimmed the bushes to the ground leaving the main canes shorter and then I moved the irrigation tube. All suggestions were to remove the black canes so that they didn't infect other canes....well that made me cut the bushes severely as a lot of black canes were attached to the main node. I will put some fertilizer down and this may be a waste of time? I am new to roses and they are treated a bit differently than some of our other plants....so I'm wondering, am I doing the right thing? Help!!:)
