A widely used ornamental landscape plant, Anthony Waterer spirea is a flowering deciduous shrub that originates from Japan and China. This hardy, easy to grow shrub has a dense, rounded habit and bears soft clusters of dark pink flowers in mid to late summer. Spent flowers can be removed to extend flowering. Its newly emerging foliage is red-purple in color and matures to bright green.
Best grown in full sun and tolerant of a wide range of soils, ‘Anthony Waterer’ is a highly versatile landscape shrub that looks great in mixed borders, hedges or planted in masses.
Plant in spring or fall. Space plants 2 to 15 feet apart, depending on the expected mature size of the plant. Dig a hole only as deep as the root ball and 2 to 3 times as wide. If your soil is in very poor condition, amend the soil you’ve removed from the hole with a small amount of compost. Otherwise don’t amend it at all. Carefully remove the plant from the container and set it in the hole. Fill in around the root ball with soil until the hole is about half filled. Then firm the soil and water thoroughly. Fill the hole with the remaining soil and water again. Form a raised ridge of soil around the perimeter of the hole so it acts like a berm to help hold in water.
Apply a layer of compost under the tree each spring, spreading it out to the dripline (the area under the outermost branches). Add a 2-inch layer of mulch to retain moisture and control weeds. Water plants during the summer if rainfall is less than 1 inch per week. Deadheading spent flowers will sometimes induce a second flowering. Most spireas can be pruned after flowering to reduce height and maintain the desired shape. However, Japanese and bumald spireas should be pruned in early spring to promote the best flowering. Remove dead, diseased, and broken branches anytime. Spireas can be severely pruned and will grow and flower again.
