Causes and treatments for yellow leaves of purple cherry plum

1. Scientific fertilization

Reason: Prunus armeniaca is a fertilizer-loving plant. Insufficient fertilizer will cause poor leaf development and yellow leaves. However, do not apply too much fertilizer. If the concentration is too high, root rot may occur and the leaves may turn yellow.

Treatment: The growth process of Prunus armeniaca consumes a lot of nutrients. The nutrients in the soil alone are far from enough, and nutrients need to be supplemented by fertilizers, which should be applied about once every 15 days. Fertilizers should be of milder types, such as human urine, compost, beer water, etc.

2. Increase Lighting

Reason: The demand for light of Prunus armeniaca is relatively high. Insufficient light will affect its ornamental value, and yellow leaves may appear due to the obstruction of photosynthesis.

Solution: It has a high demand for light. It needs 6 hours of light a day to meet its needs for sunlight. Try to place it in a sunny place, such as a balcony, window, etc. But be careful not to expose it to the scorching sun.

3. Reasonable watering

Reason: Purple cherry plum likes dry and ventilated environment, and cannot adapt to moist and humid growing environment. Excessive drought, waterlogging and poor soil drainage can easily cause yellow leaves.

Solution: Observe its growth status. If it is short of water, water it in time, control the amount, and not too thoroughly. If root rot occurs during the rainy season, it should be pruned in time. Watering should be based on the "watering when dry and watering when wet" method. When watering is needed, the amount of water does not need to be too large, just make sure the soil is completely moist.
