Calpa trees have temperature requirements and are suitable for planting in the south. If the temperature exceeds 20 degrees, water should be applied every other day. If the temperature is low, water should be applied once or twice a week. When planting, mix base fertilizer into the soil, and then frequently apply manure to the soil. The planting place should be facing the sun, and the lighting time should be no less than eight hours.

1. Maintenance methods

1. Maintenance methods

1. Temperature: Its normal temperature is between fifteen and twenty-five degrees. It is neither cold nor heat-resistant. It is suitable for planting in the south because the plant is relatively large. For breeding in the north, it is difficult to implement antifreeze measures.

2. Watering: It likes a slightly humid environment. Therefore, it is necessary to keep water in the soil for a long time, but there should be no accumulation of water. Under normal circumstances, if the temperature exceeds 20 degrees, watering should be done every other day. If the temperature is relatively low, watering once or twice a week is sufficient.

3. Fertilization: It likes fertilizer, except when planting In addition to adding base fertilizer to the soil, you also need to frequently add fertilizers with mild fertilizer effects such as manure, bone meal, and retting fertilizer to the soil. This will help promote the growth of plant branches and leaves.

4. Lighting: It is suitable for a sunny environment To grow, the planting place should be chosen in a sunny place, and the lighting time should not be less than eight hours a day.

2. Breeding skills

1 Propagation: Catalpa trees can be propagated using the root burial method. The propagation time is selected in late March. Roots that are one to two centimeters thick and 15 to 20 centimeters in length are selected from plants that are strong and have a diameter at breast height of more than 15 centimeters. Cut the strips diagonally, make sure the cuts are smooth, and bury them diagonally into the soil. After burying, press the soil tightly and allow it to be drained once.

2. Pruning: It has strong germination ability and needs Prune often. In spring, select three to four main trunks and cut off all the others. After a period of time, if new sprouts grow on the main trunk, all should be removed. This can concentrate nutrients and ensure the plant's shape.

3. Problem diagnosis

1 . Insect pests: It is more susceptible to pests such as Paulownia tortoise shell. When the insects are still in the larval stage, you need to spray 3000 times of high-osmosis fenoxycarb emulsifiable concentrate once or twice a week.

2. Disease: Catalpa trees are prone to disease when the climate is humid. If the plant is infected with anthracnose, the leaves will fall off when the disease occurs, so ventilation needs to be strengthened during the maintenance process. If the plant is infected with anthracnose, it can be sprayed with polyclonal cleaning agent.

4. Other questions

1 , Toxicity: It is non-toxic. Not only is it not toxic, the bark can also be used, and the leaves have detoxification effects.

2. Whether it is suitable for indoor breeding: if it has been treated The latter potted plants can be grown indoors. If they have not been treated, it is not recommended to be grown indoors because they grow too fast and the plants are too large to be suitable for home cultivation.
