|I planted 4 knockout roses last year and right now they are full of flowers but the leaves are full of tiny holes. Could you suggest something to use on them (preferrably systemic). Also, I haven't fertilized them yet this spring. Is it too late to do this and could you recommend a product to use?

|Bayer 2-in-1 Systemic Rose & Flower Care feeds as well as controls insect pests; Bayer Systemic All-in-One Rose & Flower Care controls insects, prevents against diseases, and feeds your plants. Either one will help keep your roses healthy. Apply according to label directions.
