Black Spots on Rose Bushes

To prevent black spots, insects, and mites on your roses use Fungaside 3 in 1, once a month. When watering your roses do not spray the entire bush. Moisture on the leaves increases the chance for black spots to develop. Use a soaker hose early in the morning or late in the evening to prevent sunburn. If you start to see signs of black spots increase Fungaside use, to 7-14 days for treatment until black spots diminish.
