The leaves should come back so unless the cane turns black just leave it alone.

Yep it will releaf in time...

Next year when you first start seeing damage on a few leaves take action either by hand picking them off or spraying... Least toxic spray would be safers insect killing soap OR try spinosad...Spray in the evening as Spinosad can harm bees...Always follow directions..

I found a slug and snail bait (tiny pellets) last year that is safe to use around pets--Natria, by Bayer. My Miniature rose got decimated already this year so I was actually just out today applying this. HTH.

Although I'm not familiar with that particular product, I think that's for regular slugs, as in mollusks. It's for snails and slugs(snails without shells.) Rose slugs are the larvae of the saw fly, so I'm not so sure this product would work. I think you need an insecticide, if that's the route you're going to go. Jim gave some good, less toxic, suggestions. Some of my roses have been hit especially hard this year, too. So ugly, isn't it? Lisa

Different type of slug fun2learn as Lisa said...

Oh- I didn't realize that rose slugs were different. Do regular slugs and snails eat rose leaves?? Something has been chomping on mine!

Yes this is the time of year when rose slugs eat your leaves. Of course thru out the year there are other insects that will damage your leaves. I have never known why they call these thing slugs. They look like little green wormy things about the same color as the leaf. Usually found on the bottom of your leaves. Google rose slugs to see photos.

Thanks!
