1. Water thoroughly and spray the roses with plain water first.

2. Pour one heap or 4 teaspoons of baking soda into one gallon of water. Add a few drops of dishwashing liquid (or a teaspoon of flea dog shampoo) to help the mixture "stick" or "stay-put" and a few drops of baby oil. Mix thoroughly, and mix again if you set it down for awhile.

3. Pour into a pump spray bottle and spray your rose foliage with this mixture. Repeat once or twice a month to prevent fungus growth.

4.Works best if you spray in the morning or evening, not during the day under full sun.
