What to do if the leaves of pine red plum turn yellow

1. Reasons

Summer heat burns

Pine Red Plum likes plenty of sunlight, but the temperature is too high in summer and the sunlight is too strong. Long-term high temperature and scorching sun exposure can cause burns and local water loss on the leaves of the Pine Red Plum, which will cause the leaves to dry out and turn yellow.

Excessive dehydration

The principle of watering pine red plum is to water it when the soil in the pot is dry, and water it thoroughly each time.

If the soil in the pot of pine red plum is too dry, the leaves will lack the necessary water, which will also cause the leaves of pine red plum to wither.

Overfertilization

If too much fertilizer is applied to the pine red plum, the roots will be burned and the leaves of the pine red plum will turn yellow.

Soil compaction and salinization

Problems such as soil compaction and salinization can cause root damage to the pine red plum, resulting in yellowing of the pine red plum leaves.

Temperature is too low

The temperature is too low in winter and the plant is not placed in the greenhouse for maintenance in time, causing frostbite on the plant. This is also one of the reasons why the leaves of the plant turn yellow.

2. What to do

Summer shade

In hot summer weather, you can place the pine red plum in a cool place to absorb the scattered light from the sun.

Reasonable watering

During the growing period of Prunus armeniaca, the soil in the pot should be kept moist. In the hot summer weather, you can spray water mist around the Prunus armeniaca to increase the air humidity.

Moderate fertilization

During the growing period of pine red plum, apply decomposed thin liquid fertilizer once every 1 to 2 months, and water it appropriately to keep the potting soil moist.

Controlling soil composition

Pine red plum is suitable for growing in slightly acidic soil that is rich in humus, loose, fertile and well-drained.

When the soil is too alkaline, use 5% ferrous sulfate solution to improve it, and the pH value should be between 6.5 and 7.0.

Maintaining Temperature

The cold resistance of Prunus armeniaca is not very strong, and the temperature must be kept above -1℃ in winter. Therefore, it can only be grown in pots for viewing in the north, but can be planted directly in the open field in the south.
