I bought a dormant oil spray kit for my fruit trees & it said on the box to use on Roses. Made sense & I spray it on everything with bark… raspberries, rose of Sharon x 2 & roses x12. Beautiful flowers all summer, mid summer got some aphids & fungus… made a spray with nemo oil. Dormant spray goes on before buds open, I just did again this spring
