How to Deadhead Agapanthus

Agapanthus, more commonly known as the lily-of-the-Nile, produces umbels of large flowers during the summer months. The flowers resemble lilies when in full bloom and come in a range of colors depending on the agapanthus variety. Deadheading, which removes the old wilted flowers, prevents the agapanthus from setting seeds. Seed formation diverts plant energy from flower bud formation, limiting the amount of blooms on your plants. By deadheading you encourage your agapanthus to produce more flowers through the summer season.

1. • 1

     Pinch off the individual blossoms in each flowering umbel after they begin to wilt. Grasp the base of the flower between your thumb and forefinger and break it off at its base.

     Cut off the entire umbel once all the flowers buds at the top finish blooming. Cut off the entire stem with shears, making the cut where the stem emerges from the foliage near the base of the plant.

     Inspect the agapanthus once a week for dead or declining blooms and umbels. Deadhead as needed, by removing individual flowers or entire stalks, throughout the summer months.
