Olivia from Dunn, Nc writes

Can lime-sulfur spray be used when roses are fully leafed & blooming?

Hope to spray mulch to control/overcome blackspot. Preventing mites would be doubly helpful! If 1/2 oz/gal is used, will it cause defoliation?

Answer:

Hi-Yield Improved Lime Sulfur Spray states on the product label for summer foilage spraying: Apply 1/2 fl. oz. per gallon of water.  Apply at 10 to 15 day intervals in Growing Season for blackspot and red spider mites on roses.
