Please help...something is damaging my roses
I have noticed this problem for the past two weeks and it seems to be getting worse. I have been spraying Bayer disease control every week, to build up the immunity, and then I was going to continue with a every two week spraying regimen. I am wondering if this is damage from the spray (it's also been hot hear in the upper 80's), or if this is something else. I have fertilized them, but it was about 2 months ago. I have also notice mole/vole tunnels in my rose beds. Please help! It's much appreciated...
As far as the blooms go, they are all normal, it's the leaves that show damage. New growth hasn't shown any damage so far. The leaves start out with a yellow and the leaves end up turing brown around the edges. This is occurring on most of my roses...
Here are the pictures:
new growth looking healthy
Thanks so much!
