Black spot (Diplocarpon rosae) is a fungal disease causing distinctive black spots with fringed yellow margins on rose leaves, leading to premature leaf drop. It thrives in humid conditions. Control involves prompt removal and destruction of affected leaves (do not compost). Ensure good air circulation, prune out congested growth, and choose resistant rose varieties. Fungicides can be used as a preventative measure in susceptible varieties, but cultural practices are key.
