Black Spot Killer For Roses, Rose Bushes - cooking recipe

Ingredients

1 tablespoon cider vinegar
32 ounces water
32 ounces spray bottle

Preparation

Fill the spray bottle with tap water, add 1 tablespoon of vinegar and shake to mix.
Spray the effected bushes thoroughly every morning until the problem goes away. It's very important that you do it in the morning so the leaves dry. Spray undersides of leaves as best you can.
After you kill the black spot, spray the bush about once per week to avoid a recurrance.
