The reason for the yellowing of pine red plum leaves how to deal with the yellowing of pine red plum leaves

Songhong plum is a very beautiful plant, breeding will be pleasing to the eye, but sometimes there are some conditions in plant culture, such as yellowing leaves. How should we deal with this situation?

The main results are as follows: 1. Soil consolidation leads to yellowing (salinization) of pine red plum leaves: soil consolidation, or salinization, will cause damage to the roots of pine red plum, resulting in yellowing of pine red plum leaves.

Solution: pine red plum is suitable for growing in slightly acidic soil rich in humus, loose and fertile, and well drained. When the soil alkalinity is too high, 5% ferrous sulfate solution should be used to improve the soil, and the pH value should be in the range of 6.57.0.

2. Long-term lack of water leads to yellowing of pine red plum leaves (dry yellow): the dry basin soil of pine red plum will lead to withered leaves of pine red plum. It is necessary to keep the basin soil moist during the growing period of pine red plum. On hot days in summer, water can be sprayed around pine red plum to increase air humidity. It can also achieve the heating effect.

Solution: the watering principle of Songhongmei is to see that the basin soil is dry and then water it, and every time it is watered thoroughly.

3. Sun exposure leads to yellowing of Songhongmei leaves: Songhongmei likes plenty of sunshine, but it should be shaded under the hot summer sun. Long-term high temperature and scorching sun exposure will lead to burns and local water loss of Songhongmei leaves, resulting in yellowing of leaves.

Solution: in hot summer weather, you can put Songhongmei in a cool place with scattered light.

4. Too low temperature leads to yellowing of Songhongmei leaves: too low temperature in winter leads to frostbite and yellowing of Songhongmei.

Solution: the cold tolerance of Songhongmei is not very strong, and the temperature should be kept above-1 ℃ in winter, so it can only be watched in pot in the north, but I can plant it directly in the south.

5. Excessive fertilization of Songhongmei leads to yellowing of leaves (fat yellow): excessive fertilization of Songhongmei will cause Songhongmei to burn roots and cause Songhongmei leaves to turn yellow.

Solution: during the growing period of Songhongmei, apply mature dilute liquid fertilizer every 1 to 2 months, water properly at ordinary times, and moisturize the basin soil.
