Rose questions for my rose expert friends, folks...
Last year, my roses had terrible black spot. It was worse because I didn't know what it was so I didn't treat it until it was pretty far gone. This year, I'm trying to be a little more pro-active so sprayed them yesterday with an organic fungicide/insecticide/miticide. They look MUCH better than last year. A few leaves had black spot so I removed them.
HOWEVER, some leaves have rusty brown spots -- is that another type of fungus?
Also, something is eating holes in the leaves... An insect of some sort?
Besides spraying, anything else I could do?
I'm determined to bring these roses back to full health. They've been fed with rose food too.
Thanks in advance, guys!

With this heat, humidity and rains, fungus are rampant this year
Rust is yet another species of fungus and must be treated as such.
Fungicides will arrest the problem, but not get rid of what is already there.
Pick off foliage if you can.
Regular treatments will keep it under control.
Insecticide may be needed for holes.
Hydrangea may have burn spots from water sitting on foliage and working much like a magnifying glass with the sun and scorches the tender leaf.
A common problem with rain and over head watering.
Hope this helps.
