All-Purpose, Safe Rose & Plant Spray

Bye-bye black spot

Originally published one year ago. Updated to include the addition of Neem oil as an option.

Below are the directions for mixing up a safe spray to treat black spot on roses and discourage aphids and other insects. I use this spray weekly on my roses. I also use it if I see mildew or other fungal type disease on any plant.

You need:
  • 1 ½ Tablespoon baking soda
  • 2 Tablespoon vegetable oil (you can also use Neem oil)
  • 1 ½ Tablespoon liquid soap
  • 1 Gallon Water
  • 1 Tablespoon Vinegar

I mix all the ingredients in an inexpensive pressure sprayer. These are normally on sale for $12 to $15 dollars.

Plan to spray early in the morning before temperatures reach 80 degrees. I also like to spray on days when no rain is expected so the mixture has time to dry.

Regular use greatly reduces the incidence of black spot. I have also successfully used this spray to combat white flies.

Give it a try in your garden and let me know how it works for you!
