Spots on rose bush leaves
We inherited a pretty white floribunda (I think) rose in a large pot. After all the new leaves popped out they all got these small brown spots on the top side of the leaves. I sprayed the plant with an organic plant bug spray and a couple days later all the leaves had fallen off. Now the plant has all new leaves and they are beginning to get the same brown spots. Does anyone have any idea what they are and how to get rid of them? Thanks!
