Why have my roses got leaf curl and dying on new growth.
I have recently sprayed all twelve rose bushes with Bayer Garden Provado Ultimate Bug Killer, resulting in new growth getting leaf curl and becoming limp. This is mainly on recently purchased roses. The established climbing rose has burn marks and curling on the leaves. I used the concentrate as described on the container, with a pump spray. Please advise on further treatment to save these lovely plants. Thank you. Ken S
