Plant Empire® Ice Dragon® Spiraea in well-drained soil with full sun to partial shade. Space plants 3-4 feet apart. Water regularly during the first growing season to establish a deep, extensive root system. Once established, water as needed, especially during dry spells. 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 cold and wind.
