How To Control Black Spot Of Roses - Rose Tree Black Spot Fungus Disease

Gardeners who want to keep their rose garden the envy of the neighborhood should plan to keep black spot fungus disease under control. Black spot is rose "public enemy number one" and commonly makes its appearance in the spring following warm, wet weather.

Symptoms of black spot begin on leaves as small, pin-head sized black or dark brown spots which are circular in shape. The spots increase in size, and infected leaves eventually turn yellow and fall from the plant.
