If you see black spot on your rose bushes, it’s too late to do anything about it — you’ll have to remove the diseased leaves and canes and throw them away. However, if you want to keep your roses from taking ill in the first place, it’s easy to cook up an organic preventative.

Mix one tablespoon of baking soda, one tablespoon of vegetable oil, and one tablespoon of Fels-Naphtha soap solution with a gallon of water, and spray the mixture on your rose bushes every couple of weeks. It’s imperative that you do this with any varieties that have yellow roses in their ancestry, as yellow roses are especially susceptible to black spot.
