What if Acer truncatum leaves keep falling?

Acer truncatum is a very good indoor plant. It is easy to survive and grow well in the greenhouse. However, in the process of family maintenance, it is easy to cause symptoms such as dead leaves, fallen leaves and dead branches, and sometimes it will die. For Acer truncatum, which is difficult to maintain, we should pay attention to the following aspects:

1. Water: water thoroughly at one time, but no water can accumulate; Potted soil should be kept moist and sprayed with water every day; Don't water Acer truncatum directly with tap water (that is, hard water). Our domestic water generally contains bleaching powder, which is alkaline. If watered directly, the soil in the basin will be salinized. If you water Acer truncatum with such water, you should also leave it for a period of time, and then water it after the substances in the water precipitate.

2. Temperature: The suitable temperature for Acer truncatum is 22-26℃.

3. Fertilization: ① Apply nitrogen fertilizer once a month, combined with watering;

② FeSO4 can be used to adjust the pH value when watering. Acer truncatum likes acidic humus soil, and the soil in the north is alkaline. In the process of maintaining Acer truncatum Bunge, we must pay attention to the pH of the soil. Water should be "dry when wet". Don't water the tap water directly. The tap water in the north is too "hard" (alkaline), and the soil of Acer truncatum likes acidity.

4. Soil: soil conditions should be checked frequently, and soil replacement can be considered if necessary; You should also loosen the soil regularly.

5. Other conditions: ① Lighting and ventilation: Acer truncatum is a shade-tolerant tree species, but it should also be given moderate lighting and ventilation. Scattered light is most suitable to be moved to the balcony and other places with good sunshine and ventilation for maintenance every once in a while;

(2) Put it in front of the windowsill in winter and let it grow under the light. It is optional in spring and autumn. It is very important to avoid direct sunlight and water it in summer. It is not allowed to water directly with tap water, because tap water contains disinfection substances such as chlorine. If it is watered with tap water, it is best to use it in the sun for a day.

Look at the picture, the leaves are black and yellow, lacking in fertilizer. It is better to supplement some fertilizers and pay attention to others.
