Planting & Care

Plant your Slim™ Bottlebrush in a location receiving full sun with well-draining soil, digging a hole twice the width of the root ball. Water thoroughly after planting, then maintain consistent soil moisture while allowing it to dry slightly between waterings; apply mulch to conserve moisture and regulate soil temperature. Feed with a balanced, slow-release fertilizer each spring, and prune after flowering ends to maintain its compact silhouette and encourage dense branching. This evergreen is remarkably tolerant of heat and drought conditions once its root system is established, making it an excellent choice for water-conscious landscapes.
