Fraxinus mandshurica is a common landscaping tree species, which is often used as the courtyard garden of urban streets, parks, communities, villas, courtyards and other places. Today, I will introduce the knowledge about ash tree protection.

First of all, Fraxinus mandshurica needs suitable soil and plenty of sunshine. Ash trees like dry and breathable soil, and their roots should not be soaked in water. Being wet for a long time can easily lead to diseases. The sunshine is strong in summer, so it needs to be watered in time. In winter, we should control the amount of watering and keep the environment dry. At the same time, in order to ensure the growth, ash trees need to apply compound fertilizer once a year to ensure the normal growth and development of trees.

Secondly, ash trees need pruning and shaping in time. Pruning ash trees should be done in spring. Cut off the dry or damaged branches and internal branches first, and then trim and shape the messy branches. The plastic ash tree will be more neat and beautiful, and the tree will be more robust and powerful. In addition, ash trees are often threatened by pests and diseases. Common diseases are root rot and branch blight. If these problems are found, scientific measures should be taken in time, such as proper crown opening, keeping ventilation and spraying pesticides frequently to prevent them.

Finally, ash tree is a kind of plant sensitive to environmental pollution. It needs to keep the air humidity and prevent it from being affected by heavily polluted areas.

To sum up, Fraxinus mandshurica, as a common urban greening tree species, has the characteristics of beauty, environmental protection and rapid growth. If we can maintain it scientifically, we can not only prolong the life of the tree, but also make it healthier, more energetic and make our life better.
