What's the matter with the yellow leaves of elm, three reasons for the yellow leaves falling off and the treatment strategies?

The yellow leaves of elm fall off because of too much water, too low temperature and insufficient nutrients. Remember to water the elm tree dry but not wet. Even in high temperature season, fertilize it every 10 ~ 15 days. Generally, it is mainly composed of decomposed organic fertilizer or cake fertilizer and water. In the process of maintenance, elm can be changed every two years, and it is best to maintain it indoors when the temperature is low in winter.

Causes of yellow leaves falling off of elm

Too much water: watering the elm tree too much water will cause its yellow leaves to fall off. Elm is afraid of waterlogging. If it is watered too much or it is not drained in time after being caught in the rain, its roots will be damaged and its leaves will turn yellow.

Low temperature: Elm likes warm growing environment, and its cold tolerance is relatively poor. If the temperature of the cultivation environment is too low, it will freeze, affect the growth of leaves, and then appear physiological yellow leaves.

Insufficient nutrients: elm likes fertilizer. If they don't apply enough fertilizer during the growing period or don't change the soil for a long time, they will all lack the nutrients needed for plant growth, and then the yellow leaves will fall off.
