Stay on top of rose pests and disease. If you notice a black spot, pick off affected leaves right away so it doesn't spread. Aphids can be managed in their early stages with organic insecticidal soap or a quick blast of water, while caterpillars, if noticed quickly, can be picked off and relocated to a wild area of the garden. Remember, caterpillars do become moths and butterflies, which are valuable pollinators for our vegetable gardens.If you want to avoid any pest problems yet still enjoy roses in your garden, modern landscape roses (as seen above) such as Knockout, Drift, Oso Easy and Flower Carpet roses create a long-lasting flower display in the garden, yet need little care and fussing to do well. They're even well suited to a totally no-spray garden.
