Can I plant some plants that leaf-cutter bees like to cut, so I can reduce damage to my roses?

I've heard leaf-cutter bees are very beneficial to the garden and aren't harmful, they just make roses look terrible. There must be tons in my garden because my roses don't have just a few holes, they are quite ragged. Are there other plants they would use instead if I planted them? Or will that just create an even bigger population and they'll still ruin half of my rose leaves? Thanks

The leaf-cutter bee does cut leaves for it's nest.

Control


Insecticides are ineffective for prevention of leaf cutting. The only known control of leaf injuries is to cover susceptible plants with cheesecloth or other loose netting during periods when leafcutter bees are most active. Numbers of leafcutter bees in an area can be reduced if breeding sites are eliminated, although these might be difficult to detect. Look for rotting boards, with sawdust pushed out of excavated tunnels, or thick stemmed plants with hollowed openings. Leafcutter bees can be prevented from tunneling into rose canes by sealing exposed pith as canes are pruned. This can be easily achieved by placing a thumb tack, bit of sealing wax or white glue on the opening.
Reply:Bees or ants. Bees do not cut leaves. They simply drink nectar and collect pollen to make honey and beeswax. Ants actually cut leaves to make a fungus as their food supply. May want to try some stuff like baking soda to keep the ants away. Some stuff you may find at a hardware store. Plants with big leaves like ferns may be more inviting to the insects.
Reply:Might be Japanese Beetle. plant WHITE geraniums in between roses, it works
Reply:go to the hardware store there is a spray you can buy to spray your roses to get rid of the bugs that would be the easiest thing to do.
