Japanese Flowering Cherry: A Guide to Growing and Care
Overview
Japanese flowering cherry trees (Prunus serrulata) are beloved for their stunning pink blossoms that herald the arrival of spring. These fast-growing, ornamental trees are a popular choice for home landscapes, parks, and gardens. While they are relatively easy to care for, there are some specific requirements to ensure they thrive.
Growing Conditions
Japanese flowering cherry trees prefer well-drained, loamy soil with a neutral pH. They require full sun for optimal blooming, but can tolerate partial shade. These trees are hardy in USDA hardiness zones 5b to 8a, and can withstand temperatures as low as -10 degrees Fahrenheit.
Planting
Plant Japanese flowering cherry trees in early fall to give them time to establish a strong root system before winter. Choose a planting site with well-drained soil and full sun. Dig a hole twice as wide as the root ball and just as deep. Place the tree in the hole and backfill with a mixture of soil and compost. Water deeply to settle the soil.
Watering and Fertilizing
Japanese flowering cherry trees require regular watering, especially during the hot summer months. Water deeply, allowing the water to penetrate to the roots. Once established, these trees can tolerate short droughts. Fertilize annually in the spring with a fertilizer specifically formulated for cherry trees.
Pruning
Japanese flowering cherry trees require minimal pruning. Remove any dead or diseased branches, and prune to shape the tree as desired. Avoid excessive pruning, as this can make the tree more susceptible to pests and diseases.
Propagation
Japanese flowering cherry trees are typically grafted onto a hardier rootstock. Propagating them from seed is not usually successful. However, stem cuttings can be taken in the summer months.
Pests and Diseases
Japanese flowering cherry trees are susceptible to a number of pests and diseases, including aphids, scale insects, and Japanese beetles. They can also be affected by leaf spot, powdery mildew, and fire blight. Regular inspection and prompt treatment are essential for keeping these problems under control.
Common Problems
One common problem with Japanese flowering cherry trees is bark splitting. This can be caused by a number of factors, including drought, sunscald, and mechanical damage. It is important to treat bark splits promptly to prevent further damage.
Uses in the Landscape
Japanese flowering cherry trees are versatile and can be used in a variety of landscape settings. They make beautiful shade trees for small spaces, and can also be planted as specimen trees for spring display. Smaller cultivars can be grown in containers.
Additional Tips
- Japanese flowering cherry trees are toxic to pets and humans, so it is important to plant them away from areas where children and pets frequent.
- These trees are relatively short-lived, with an average lifespan of 15 to 25 years. However, with proper care, they can live for much longer.
- Japanese flowering cherry trees do not typically bear fruit. If you are looking for a cherry tree that produces fruit, choose a cultivar of the sweet cherry group (Prunus avium) or tart/sour cherry group (Prunus cerasus).
