What is good rose bug spray – knockout variety?
I have three bushes in front of property with English lavender between each. Half day sunshine. I thought they were pest resistant. Leaves have holes of different sizes. Sprayed with ammonia and dish soap mixture - Has not stopped the bugs from eating them.
I like to use Bayer Tree and shrub granules. It has some fertilizer in it and also a systemic that moves up throughout the rosebush through the root system. Apply per label directions for Ornamental shrubs. They also have a Rose and Flower granules but I like the tree and shrub better. As far as sprays go, you could use the Bayer Complete Insecticide spray.
