The elm tree is a common tall tree species widely used in park and residential area landscaping. In addition to its high ornamental value, the bark and leaves of the elm tree can also be used as medicine, with good medicinal effects. Let's take a closer look at the elm leaves!
【Uses of Elm Leaves】
Elm leaves have the effects of clearing heat, detoxification, and cooling blood. They are mainly used to treat painful sores and excessive bleeding during menstruation. They can also be used to treat eczema or pustular sores. If these symptoms occur, you can choose this traditional Chinese medicine for treatment. Fresh leaves can be crushed and applied externally, or you can choose to soak them in water. However, during the treatment, avoid consuming fishy foods to prevent worsening of clinical symptoms.
【Differences between Elm and Elm Trees】
1. The leaves are different. The serrations on the sides of elm leaves are irregular, while elm leaves are generally symmetrical. Elm leaves are usually smaller and thicker, while elm leaves are usually larger and thinner. The serrations on the edges of elm leaves are unique peach-shaped serrations, while elm trees do not have this feature.
2. The flowers are different. Elm trees have bisexual flowers, while elm trees have unisexual flowers. Male flowers of elm trees usually grow on the lower part of new branches, while female flowers usually grow on the upper part of new branches.
3. The barks are different. The bark of elm trees is gray or dark gray. The bark of young trees is relatively smooth, while the bark of old trees is rough and longitudinally cracked, making it rough and strip-like. The bark of elm trees is gray or reddish-brown, and the young branches are covered with white soft hairs.
【Growth Environment of Elm Trees】
Elm trees are widely used in park landscaping. They can be used for flower appreciation, leaf appreciation, and their branches are tall and upright. Elm trees can be planted in groups to form a landscape flower sea, or a single tree can be planted as a unique landscape feature, which can be coordinated with landscape rockeries, resulting in beautiful scenery.
Maintenance throughout the year is simple, mainly involving pruning the crown, fertilizing, removing weeds, and controlling pests. Elm trees are less prone to diseases and pests. The main prevention measure is to prevent the larvae of large green caterpillars from eating the leaves.
Elm trees have moderate tolerance to drought. They can withstand mild and moderate drought, but they cannot survive severe drought. Their drought resistance is not as good as that of ginkgo trees and willow trees with long root systems.
Elm trees can also grow in various types of soil. They are not strict in soil requirements and can grow in loess soil, black clay soil, and sandy soil. However, the soil should have good drainage and be flat. It should be able to prevent water from accumulating on the ground during continuous rainfall in summer and drain water rapidly. Slightly saline-alkaline soil is also suitable for growth.
