Crataegus phaenopyrum, commonly known as Washington hawthorn, is a deciduous tree in the Rosaceae family. Native to the southeastern United States, it is known for its attractive white flowers, red fruit, and vibrant fall foliage. The tree can reach heights of 25-30 feet and is often used in landscaping for its ornamental value. It undergoes a dormancy period during the winter months.
Washington hawthorn thrives in temperate climates and prefers full sun exposure. It requires moderate watering, allowing the soil to dry out partially between waterings. The tree does well in moderate temperatures and average humidity levels. Regular pruning is recommended to maintain its shape and health.
土壌
This tree prefers well-draining loamy soil with a slightly acidic to neutral pH. It can tolerate a range of soil types but performs best in fertile, well-drained soils. Ensure good drainage to prevent root rot.
肥料
A balanced fertilizer with an N-P-K ratio of 10-10-10 can be applied in early spring to support growth. Fertilize once a year to provide essential nutrients.
植え替え
If grown in a container, repotting should be done every 2-3 years or when the tree outgrows its pot. Choose a slightly larger pot with good drainage and fresh soil mix. Repot in early spring before new growth begins.
伝搬
Washington hawthorn can be propagated through seeds or cuttings. Seeds should be stratified before planting, while cuttings can be taken in late spring or early summer. Ensure the cuttings have a few leaves and are placed in a rooting medium.
剪定
Pruning should be done in late winter or early spring before new growth starts. Remove any dead, diseased, or crossing branches to maintain the tree's shape and health. Thinning the canopy can also improve air circulation.
毒性
Washington hawthorn is not known to be toxic to pets or humans. However, the thorns on the branches can cause physical injury, so handle with care.
追加
Washington hawthorn is valued for its ornamental qualities and wildlife benefits. The red berries attract birds, and the dense foliage provides shelter for various animals. It is also relatively resistant to pests and diseases, making it a low-maintenance choice for gardens and landscapes.
