1、 Soil

Paulownia grows better in some fertile soil. Avoid breeding in too sticky soil, which will affect the root respiration and growth of the plant. In addition, the large pots should be changed in time during the breeding period. When the seedlings are in the state of seedlings, they should be changed once a year. After the plants are formed, they should be changed once every 2-3 years

2、 Temperature

If you cultivate tung trees in a suitable temperature range, their growth state will be better. Try to maintain the temperature at about 15-30 ℃. If you can't reach the breeding temperature, don't let the temperature be too low or too high. In severe cold season, you need to put it indoors as soon as possible, and the room temperature should be maintained at about 5 ℃. If you raise it outdoors, you should pay attention to keeping warm

3、 Moisture

Watering should be reasonable during the maintenance period, and the specific watering amount is also different in different climates. In spring and autumn, it is usually watered once every 1-2 days, and in late autumn, it will be watered once every 2-3 days. Plants need more water in summer, so they should be watered more appropriately. In winter, the temperature is low, so they need to reduce the amount of water

4、 Precautions

The growth ability of Paulownia is very strong, so we should pay attention to pruning during breeding. In spring, it is mainly based on modeling. If the top growth is relatively high, we should appropriately cut the top, otherwise the beauty of the plant will be reduced
