The following is John Spencer's recipe for removing mold and mildew from roses:

Ingredients:

  • 1 tbs baking soda
  • 2 tbs insecticidal soap
  • 2 tbs vinegar

Adding the vinegar last (lest you have an unwanted chemical reaction), mix the three ingredients in a cup of water. Add the concoction to a gallon of water. Spray the solution on the roses.
