Yesterday this rose bush had beautiful green leafs. Today, I find them with spots like it was sprayed. Can anyone help. No one has answered this post. Someone must have seen this on a rose bush. Omg someone is trying to kill my rose.
I once had some roses whose leaves turned white-ish, similar to yours. The cause was rose slugs, aka, sawflies. You will need to monitor during the day and night to confirm if you see any pests causing the damage. I used insecticidal soaps but I suppose you could just pick them up or spray horticultural oils.
