Yes. A dormant spray of Lime-Sulfur applied after the roses have become dormant in fall or before they begin to grow in spring can, to a great degree, eliminate disease and insects that “winter over” on the plant. This is especially worthwhile if stem canker is a problem in the garden. The one caution is applying dormant spray is that the temperature must be 40 degrees or higher for 3 to 4 hours after the spray is applied.
