Second, watering too wet is easy to cause the young leaves to yellow and die, the best appropriate pine pot soil is conducive to the drainage of water in the pot, which is conducive to the recovery and growth of the root system and reduces the symptoms of leaf loss of yellow cypress orchid.
3. After winter, the indoor moisture is too dry due to new water loss and dry falling, which can increase the indoor humidity, such as opening doors and windows at intervals or spraying water on the leaf surface or spraying water on the topsoil of the pot to increase humidity and reduce the problem of leaf water loss and falling.
Lack of fertilizer, proper shade at noon, dry and watered, watering is better, it is better to add some plant growth nutrient solution when watering, and it is better to spray potassium dihydrogen phosphate on leaves frequently
There are two main reasons why the seeds of potted plants are more likely to turn yellow than the source, the first is because a domestic hydroponic plant is directly taken from tap water, and the lack of potassium in the water will lead to insufficient chlorophyll synthesis and yellowing of the leaves. The second reason is that soaking plant roots in water for too long may cause root rot, lack of oxygen, and exacerbate the deterioration of water quality. Eventually, the leaves turn yellow.
You're asking what to do if the leaves of a plant become like this. >>>More
It is infested by a pest called red spider.
Spider mites are a common destroyer in the process of cultivating flowers, and the insects are very small, less than 1 millimeter, which is not easy to detect. The way to harm is to suck the juice into the leaves with mouthparts, so that the chlorophyll is damaged, and the leaves appear gray-yellow spots or patches, and the leaves are orange, fall off, and even fall light. Insects mostly swarm on the back of flower leaves and spin silk nets to cause damage. >>>More
