There are some perfectly round small holes in the leaves and some in the smaller buds .. The tan areas do have a lace appearance . Is there anything I can use to deter these insects? This particular rose doesn't get bayer product and such because it's very close to many of my nectar plants and also some lady bug favorites, so I try not to spray it for insects , just disease. I have milkweeds/ yarrow/ joe pye just beyond this bed and I'm very careful not to spray near my butterfly plants.

You have to look on the underside of the affected leaves to see if they are still there. Probably not.
Most of us have rose slugs every year. Wasps and other predators usually control them. Next spring, watch for the damage and wipe the tiny worms off the underside with your thumb. If you can't keep up with that, spray the affected areas with a spinosad product, reaching the underside of the leaves with thorough coverage.




Definitely more than one thing going on here. For PM you can get a fungicide spray. It will keep it from getting worse but the leaves already with it on them will not clear up. You'll need to wash those off. Just use a good hard spray of water and that will also help to dislodge the rose slugs that are putting holes in the leaves. Make sure to spray up under the leaves to get the back sides where the slugs are.


I've had the same problem this spring. Had to prune the dickens out of everyone, and there's very minimal new growth from the canes I left. Most (about 90%) of the new growth were new canes from the graft, and on the plants exposed to the highest wind velocities I have lost over 70% of each of those new canes.
I tried to blame it on critters, but after the 3rd go-around I was able to stand on the deck & watch the damage occur on the last bout of storms.




I think for us in the SE, it was the combination of the cool wet summer we had and then the brutal winter. Everyone I know has lost not only roses, but all kinds of shrubs. On of my neighbors has a nice bed of hollies that have not come back. Usually these don't even lose their leaves.
I hear you about the Dr Huey roots. I had to dig up some dead roses and the roots (which were alive and well) were HUGE. I am sure I didn't get them all and will be fighting off suckers for awhile.

I have 5 new tree roses on my back deck and I noticed all 5 of them have half eaten holes on the leaves. I've read here it's the cutter bees doing the damage. I sprayed something on the trees for insects so now I'm worried I may have hurt the bee and given it poison to take back to the nest. Any answers for me?

Thanks, everyone!

Many garden centers, home improvement stores which have "garden departments", even Dollar Store type outlets sell packages of thin bamboo stakes, usually stained green. They range from a foot to six feet in length, are packaged in plastic bags and sell usually for under $5. Often the shortest lengths contain about a dozen with the longer ones containing six. They're perfect for staking the errant single stems of plants such as you describe. Kim






This was interesting and it didn't quite come out right.
But these are the colours as how they appear from further back to me.
The one colour I see most often I have no pictures of.
Go figure.
Ordphien,
Thank you. This rose is so unusual compared to the much of what I see. I find myself drawn to it. The comments on this thread, and your images have been helpful.
