The Q&A Archives: Holes In Middle Of Rose Leaves

Question: I am wondering what could be eating the foliage on my rose bushes and not even touching the roses itself, could it be bees, worms?

Answer: This late in the season I'd rule out leaf cutter bees (they remove neat little semi-circles from leaf edges in the spring and early summer months )and concentrate on caterpillars as the culprits. Some feed at night which might be why you haven't actually seen the critters, just the damage. You can inspect the undersides of the leaves to see if you can find small worms - and squish or rub them off the leaves. Your roses will begin to lose their leaves as the weather turns colder so no treatment is necessary. Just be sure to rake and remove fallen leaves so pests do not have a cozy place to spend the winter. Next spring your roses should produce healthy new foliage.
