Causes and treatments for yellowing leaves of elmleaf plum

1. Insufficient light

Reason: Prunus armeniaca is light-loving and prefers to grow in an environment with plenty of sunlight. Especially during the growing period, it must be maintained in a full-sunlight environment. If there is insufficient light, it will affect its normal growth, the plant will be very small, the branches and leaves will turn yellow, and the number of flowers will decrease.

Measures: If it is in the growing season, it needs to be moved to a full-sun environment for maintenance. Be sure to shade it when the midday sun is strongest. Adequate sunlight will speed up its recovery and growth.

2. Excessive water

Reason: Prunus armeniaca is drought-tolerant but not water-tolerant. If you water it too much, water will accumulate in the soil and the roots will not be able to breathe. The nutrients in the potting soil cannot be absorbed and transmitted to all parts of the plant in time, which will lead to malnutrition inside the plant and yellowing of the branches and leaves on the outside of the plant.

Measures: The plants need to be dug out, the water from the roots needs to be drained, and the rotten roots need to be cut off. After the roots have dried, replace the soil with neutral to slightly alkaline sandy loam and replant it.

3. Insufficient nutrients

Reason: Prunus armeniaca likes fertilizer and is resistant to strong fertilizer, so it has a strong demand for fertilizer. Sufficient nutrients can encourage it to bloom more and more colorful flowers and grow faster. If you do not pay attention to fertilizing during normal maintenance, it will grow slowly due to lack of nutrients, suffer from malnutrition, and its branches and leaves will gradually turn yellow.

Measures: Apply fertilizer in time, but not at a high concentration. When planting, you can apply some decomposed cow and horse manure as base fertilizer, and apply thin fertilizer water every ten days during the growing period. Fertilize once in spring after the flowers fall and before winter.
