Something is eating tge leaves of my rose bush. The bush was well established when I bought the house 25 years ago and I have done little to nuture it during that time. Occassional watering and pruning it back each fall. This spring something is devoring the leaves. I looked several times for aphids but did not find any. After searching the web I discovered rose slugs and found them on my bush. There doesn't seem to be many but several canes have leaves that look like lace. Will this old bush die?
