The agapanthus plant, also known as the lily of the Nile, produces clusters of blooms in blue, white or violet. Blooms generally appear from late spring to early fall. The name agapanthus is Greek and means love flower. The plant is a perennial and will grow again year after year. They grow best in zones 8a to 11, but can be grown in other areas with proper care.
Plant the agapanthus in a location that has full sun for most of the day. The soil should not be too acidic and should be loose to allow for proper drainage.
Water the agapanthus enough to keep the soil moist. Do not allow the soil to stay soggy. Do not allow it to dry out for a long period of time. Reduce watering during colder months.
Fertilize the agapanthus twice a month during spring and summer. Use a general purpose fertilizer and dilute it to half the strength that is recommended on the packaging using water. If preferred, a slow-release fertilizer can be used once in early spring instead.
Prune any damaged or dead foliage to allow new leaves to grow. Pruning to shape the plant should only be done in spring and summer. Regular pruning is not necessary and should be done sparingly.
During the winter months a layer of mulch should be applied to protect the roots from frost. Remove the mulch once warmer weather resumes.
