Overview
Kwanzan cherry trees – or Prunus serrulata – are ornamental cherries that are popular in many Japanese gardens. Native to Japan, the tree can reach heights of up to 15 meters and should be planted in sun-filled spots. The tree is noteworthy for its showy blossoms, and leaf shape. In spring, the tree produces an abundance of red or pink flowers that attract bees and other pollinators.
History
Originally founded in Japan, the tree was discovered in Tokyo by a Japanese botanist in 1876, and officially adopted as a natural monument in 1953. Since then, the popularity of Kwanzan cherry trees has spread around the world, with many landscapes and parks featuring the tree. It is now a popular choice for gardeners who want to add a striking display of colour to their garden.
Leaves and Blossoms
Kwanzan cherry trees are prized for their showy and abundant blossoms, as well as their attractive leaves. The tree displays a variety of heart-shaped and ovate leaves, ranging in colour from bright green to deep red. The leaves are also quite glossy, providing a reflective sheen when the light hits them in the right way.
In spring, the tree puts on a stunning show of bright red or pink flowers. The flowers are delicate and bell-shaped, clustered together in tight bunches. They offer visual appeal, drawing the eye and creating a stunning effect. With their delicate petals and vibrant colour, the flowers really stand out against the tree’s lush green foliage.
Pollination and Disease Resistance
The cherry blossoms are known for being hardy and very adaptable, making them ideal for a range of growing conditions. They are highly resistant to most diseases and pests, which makes them a low-maintenance choice for gardeners. Thanks to their abundant flowers, the tree is very attractive to bees and other pollinators, making them a great way to encourage biodiversity in the garden.
Pruning
The Kwanzan cherry tree should be pruned regularly in order to encourage its optimal shape and growth. It’s important to remove any dead or diseased branches, as well as to encourage a dense canopy by thinning it out. Pruning should be done in early summer, while the tree is still relatively dormant.
Soil Requirements
Kwanzan cherry trees thrive in moist and well-drained soil, such as loamy soils. The tree doesn’t tolerate damp and boggy conditions, so avoid planting it in spots where the drainage is poor. To promote healthy growth, the tree should be fertilized regularly with an organic fertilizer and mulched with a layer of wood chips or bark.
Location
The tree should be planted in a sunny spot to ensure it receives enough sunlight to thrive. Kwanzan cherry is a deciduous tree, meaning it will drop its leaves in the fall and winter. It should also be planted in a sheltered spot to protect it from strong winds, as well as extreme temperatures.
In Summary
Kwanzan cherry trees are an ideal choice for gardeners who want to enjoy a showy display of flowers in the spring. With their glossy leaves and abundant blossoms, the tree is a great way to bring a unique look to the garden. For best results, the tree should be planted in a sunny spot, with well-drained soil and in a sheltered location. With regular pruning and mulching, Kwanzan cherry trees can be kept in good condition and look stunning in the garden.
Uses in Landscaping
Kwanzan cherry trees are a popular choice for landscapes, as they offer a striking display of colour in the spring. The trees can be used to create a distinctive look and make an area stand out. They are also an ideal choice for creating a natural hedge, as they can be spaced close together to form a dense wall.
In Japanese Culture
In Japanese culture, the tree is highly regarded for its beauty and symbolism of renewal. In fact, cherry blossoms have been a major part of Japanese culture for centuries, with annual festivals dedicated to the flowering of this beautiful tree. The tree is often associated with love and celebration, and its blossoms typically represent the fragility and fleeting nature of life.
Pruning and Drying
In order to enjoy the stunning display of blooms for a longer period of time, the tree can be pruned judiciously and the blooms can also be dried. Pruning allows the tree to keep a more natural shape while also preserving the blooms. For drying, the petals should be carefully picked off and left on a flat surface indoors to air-dry. After drying, the petals can then be saved and preserved to adorn crafts and decorations.
Pests and Diseases
Kwanzan cherry trees are generally hardy and resistant to most pests and diseases. However, they can be susceptible to certain diseases and pests, especially if planted in a moist or poorly drained spot. Common diseases include black knot, leaf spot, and powdery mildew. Common pests such as aphids, mites, and scale can also affect the tree.
Winter Protection
When the tree is dormant in winter, it should be protected from extreme temperatures and winds. Mulching is an effective way to protect the root system of the tree, and help to conserve soil moisture. Pruning should also be kept to a minimum during winter, as it can cause damage to the tree if done incorrectly.
