Cover surrounding plants, foliage and landscaping with plastic sheeting. The cleaning solution used to remove black mold can harm or kill them.
Fill a bucket with equal parts chlorine bleach and water.
Dip a stiff scrub brush into the solution. Scrub the moldy spots on the brick vigorously with the brush and bleach. Rinse the scrub brush in the bleach solution frequently.
Let the bleach sit on the moldy spots of brick for about two hours. Rinse the brick thoroughly with water from the garden hose.
