Black Spot, Green curled worms and rust
I have all three. All my roses have it. For whatever reason the only problem I ever had was powdery mildew for a few years after alot of rain and then that never came back, but then two years ago I started gettting the BS, rust and worms. My husband couldn't keep up with the chemical spraying and it wasn't effective. I've been trying to read some past posts on the above three but am getting very confused....My question is this: is there something organic out there that will help with all three or do I have to use different mixtures for the three different problems? I use the Murphy's oil soap and water trick and it's great with the insects and snails because being oily the critters don't stick to it. Thanks for your help.
