If your rose leaves have circular black spots on them and yellowing around the spots sometimes, your roses have the black spot fungus disease.

Controlling Disease The Natural Way

Here are some of the most common "natural" products.

BAKING SODA: This is a home remedy for black spot and powdery mildew. Keep out of fish ponds. Mix with one gallon water and horticultural oil. 2 teaspoons of baking soda and 2 teaspoons oil.

NEEM OIL: I really recommend this product. I use it myself after my major yearly pruning. It's a botanical insecticide derived from the bark of a tree that's native to India. Spray the canes after pruning and also the soil underneath the rose. It repels pests and causes them to stop feeding. It's also effective for black spot and powdery mildew. Might not work as well in very hot weather.
