Black spot is a fungus that primarily affects roses but can also be found on other ornamental and garden plants. It can be found on flowers, fruits, and leaves and is problematic when the weather is hot and humid. Problems are greatest when leaves stay wet for 6 hours or more.
The other reason could be some insect.
The best remedy is spraying Neem Oil.
