I am having difficulty figuring out what is going on with my rose bushes!! There seem to be several problems all at once, and I hoping it is from the same source and one that is curable.
- leaves are curing up
- spots along the stems - they are brown with a little shine to them and are almost scab like. they are more like "lines" then "spots"
- blacking along the veins in the leaves
- yellowing of leaves
- some leaves have a purple hue to them
- on the back of some leaves there are the same brown shiny lines to them
I don't see any infestation of bugs. I planted garlic/thyme around the rose bushes to help keep the aphids away. It has been raining lately, but this problem has been going on for months - even in the heat of summer. I keep trimming back the infected leaves/stems, but soon there will be nothing left. It seems even my hearty knock outs are beginning to show signs now too.
I have looked hours on end on the internet to try to figure this out.. and nothing!! Please help! I am so frustrated!
