If black spot continues to appear throughout the season, it could eventually weaken the plant.
One of the best ways to deter back spot is by picking up and destroying the fallen leaves to avoid reinfection.

Putting mulch around the base of the plant will also stop rain splashing black spot spores onto new growth.
