watering

Black-eyed Susans should be watered regularly but moderately. Water once or twice per week depending on the weather; if it’s hot and/or dry, water more often. Check the soil moisture with your finger before watering to make sure it’s dry. Give the plant a good soak until water {runoff} comes out the bottom of the pot. Let the soil dry out in between waterings. Avoid overwatering as it may lead to root rot.

sunlight

Black-eyed Susan (Rudbeckia hirta 'Cappuccino') plants prefer full sun during the growing season - at least 6 hours each day. Morning sunlight is best, as it allows the plant to dry out and stay warm after a morning dew. During the summer months, plants should receive extensive sun for optimum blooming. During the winter months, they should be protected from the sun to some degree as the sun's intense rays can damage the flowers and leaves.

pruning

Black-eyed Susan (Rudbeckia hirta 'Cappuccino') should be pruned in the late winter to early spring season, before new growth appears. Prune off the dead foliage and stems from the previous season, which will help to promote new growth and blooms. Since this plant is a biennial, it would be best to establish a rejuvenation program, in which you cut back the plant by up to 1-third of its total height every 2-3 years. This practice will give you lush foliage and an abundance of blooms.
