The leaves on my knockout roses have holes in them. What causes this? The roses are coming up beautifully.

    It sounds like you have an insect munching on your roses. Some beetles have long pointy snouts and drill into the leaves to suck out the juices. Spraying the rosebushes with a good insecticide or giving them some Bayer Tree and Shrub granules should get things taken care of.
