Planting of Catalpa

The planting of Catalpa can be carried out in spring and autumn. Before planting, the planting hole should be dug. In addition, planting with soil ball can improve the survival rate. However, pay attention not to plant too deep, which will lead to stuffy buds. During planting, you should also apply some rotten base fertilizer and mix it with the planting soil. After planting, water the head water once, and then water it once three days and five days later

Water and fertilizer management of Catalpa

In the daily maintenance, we should pay attention to the water management of Catalpa trees. In addition to the first three water poured after planting, we should also choose to pour water twice between May and October. When there is more precipitation in summer, it is not too dry, so we don't need to water. In winter, we should also apply antifreeze water. After the plant has been in use for four years, it only needs to be watered with green water and antifreeze water. In addition, catalpa trees like fertilizer. When planting, apply enough base fertilizer and some urea in May, which can make the plant lush and accelerate the growth

Shaping and pruning of Catalpa

Because catalpa has strong sprouting power, it is resistant to pruning. When the new branches reach about 30cm in spring, select the appropriate main branches and cut off the redundant branches. The newly extracted buds should also be erased during the growth period. If you want to expand the crown, you need to truncate the main branches and leave the outer buds

Precautions for catalpa culture

Catalpa trees are also vulnerable to pests and diseases. Common pests include stink bug, poison moth, Paulownia beetle, catalpa bark beetle and wild borer, which can be controlled by spraying insecticides. In addition, the common disease of Catalpa is anthrax, which is easy to occur under high temperature and poor ventilation. Therefore, in addition to spraying pesticides, we should also pay attention to the water and fertilizer management of Catalpa to improve the disease resistance of the plant< span>
