First of all, water
Alsophila spinulosa is drought-tolerant, but long-term drought will cause trees to shrink and affect their growth. During the high temperature in summer, paulownia trees should be watered in time to keep the soil moist and avoid the ground soil being too dry.
Second, fertilization.
For paulownia trees, the principle of less is more appropriate. It is suitable to apply organic fertilizer in spring and autumn, but not too much. The type and dosage of fertilizer can be adjusted according to the specific situation of trees.
Third, keep the trunk clean.
Paulownia tree is a deciduous tree, which will give off a lot of yellow leaves in spring and autumn. These fallen leaves will form a thick pile of leaves on the trees, which will make the trees have poor air permeability and affect their normal growth. In order to avoid this situation, we need to clean up fallen leaves and dead branches in time in spring and autumn every year.
Fourth, trim the branches and leaves.
The branches of paulownia trees are very dense. Without pruning for a long time, the branches and leaves will be intertwined, which will hinder the normal growth of trees and produce unhealthy growth patterns. Therefore, according to the actual situation, it is necessary to prune in time to remove miscellaneous branches and dry and weak branches and leaves.
In a word, although paulownia tree belongs to one of drought-tolerant varieties, it needs to pay attention to key points such as watering, fertilizing, keeping the trunk clean and pruning branches and leaves during maintenance. In the usual daily management, we should be responsible for the meticulous care and maintenance of paulownia trees, so that it can grow healthily and bring more green vitality to our lives.
