Roses are among the most beautiful flowers in the home landscape or garden.
Blackspot is one of the most common and serious fungal diseases on rose plantings throughout Kansas. The leafspot lesions are roughly circular and have distinctive irregular, feathery margins. Individual leaves may develop multiple leafspots. At the beginning of the growing season, blackspot will start to develop on the lower leaves and will move upward through the plant as the season progresses. Infected foliage eventually turns yellow and falls off the plant.
