1、 The temperature is too high

Avocado is afraid of heat. If the temperature is too high, the leaves of the plant are easy to lose too much water, resulting in wilting and yellowing. Usually in summer, we should do a good job in cooling, spray water around, and absorb heat through water evaporation, which can play a cooling effect. At the same time, pay attention to ventilation to avoid breeding bacteria in too humid environment. In addition, air circulation can also cool down

2、 The light is too strong

Avocado leaves are prone to sunburn after exposure to strong light, resulting in their yellowing. As the plant itself likes light, it needs to ensure sufficient light, but it needs appropriate shade in the afternoon to avoid long-term exposure to strong light. If it is placed in the semi shade, the plant will not get light, and wilt will also appear, which will affect the flowering and fruiting

3、 Too little watering

Avocado likes to be wet, so insufficient water will lead to withered and yellow leaves. If it is caused by water shortage, it is necessary to replenish water to the plant in time. Regularly check the dryness and wetness of the soil. Generally, when the topsoil is slightly dry, it can be watered to maintain about 60% of the soil moisture. But don't pour too much water. This plant is not resistant to waterlogging. Too much water is easy to rot its roots

4、 Too much fertilizer

Too much fertilizer or too much fertilizer is needed for the growth of the plant, which will easily affect the growth of the plant. In this case, it is necessary to wash the basin soil immediately and wash away the excess fertilizer. In addition, if the situation is serious, it is necessary to change the pots and soil of the plants and trim the burned roots
