Plant Chroma Chameleon Common Ninebark in well-drained soil with full sun to partial shade. Space plants 4-6 feet apart. Water regularly during the first growing season to establish a deep, extensive root system. Once established, reduce frequency, allowing soil to dry between waterings. Prune in late winter or early spring to maintain shape and encourage new growth. Fertilize in early spring with a balanced, slow-release fertilizer. Protect from extreme heat and cold.
