The leaves of Ping an tree are yellowing, wilting and falling leaves to see if they are the following reasons.

Ping an tree means peace and auspiciousness, and the tree is dignified and its leaves are bright green, so it is deeply loved by many flower friends. Family breeding Ping an tree, the most common problem is the leaf yellowing, wilting and defoliation phenomenon, roughly for the following reasons.

1. Too much watering, stagnant water in the basin or long-term lack of water. Ping an trees like to grow in a moist environment, but no water can be accumulated in the basin. Long-term stagnant water will lead to root suffocation, unable to provide nutrients to the tree, resulting in yellowing and wilting of leaves and a large number of fallen leaves. Long-term lack of water can also lead to leaf wilting and sagging. Watering the safe tree is suggested to see dry and wet. If the basin soil is hardened and the water permeability is not good, it can loosen the soil in the basin without harming the root system and increase the water permeability and air permeability of the soil. During the low temperature period in winter, the climate is dry, reduce watering, spray more water on leaves, and stop fertilizing.

two。 The air is not humid enough. Phalaenopsis abounds in the original living environment of Ping an Tree, and flower friends who have raised Phalaenopsis all know that Phalaenopsis has higher requirements for environmental humidity. Therefore, the family breeding Ping an tree, but also try to create a warm and humid living environment for it. The most suitable growth temperature of Ping an tree is 20: 30 ℃, and the air humidity is about 80%. Therefore, during the high temperature period in summer, you can spray water to the leaves every day to cool down; during the low temperature period in winter, when the climate is dry, you should also spray the leaves regularly to humidify the tree body to prevent yellow leaves from falling.

3. Light is too strong or too weak. The original living environment of Ping an tree is in the jungle and likes to have enough scattered light. Excessive light in summer should shade the trees to prevent the leaves from wilting and sagging caused by strong light exposure. Long-term shade will also cause the leaves can not fully carry out photosynthesis, resulting in leaves yellowing, lack of spirit. If you are in courtyard farming, you can put it under a shaded tree, and enough oblique light can meet its growth needs. For indoor breeding, it is recommended that it be moved to a ventilated and astigmatic place from time to time to appropriately increase the photosynthetic area to prevent the leaves from yellowing and falling off caused by long-term shade.

4. Chlorosis caused by iron deficiency. This is easy to distinguish. If your young leaves of Ping an tree are yellow at the edges, and the veins are green, and the whole leaf is a typical grid structure, it means that the plant is iron deficient. Serious iron deficiency will cause a large area of yellow leaves and defoliation until death. The root of the plant can be irrigated with ferrous sulfate solution of 1RU 2000 every 7 days, with an interval of 7 days, and it can be significantly improved after 3 times. Ping an tree likes slightly acidic soil, in addition to the slightly acidic soil with rotten leaf soil or pine needle soil, long-term tap water watering flowers will also cause soil alkalinization. It is recommended to irrigate the plant with ferrous sulfate solution of 1% ferrous sulfate once a month to prevent iron deficiency yellowing of leaves.

5. Fat damage or lack of fertilizer. Ping an trees like fertilizer, but excessive fertilization or long-term application of fertilizer is easy to cause root burning. When the root system is damaged, it will yellowing and wilting on the leaves; lack of fertilizer will lead to insufficient nutrient supply of leaves, resulting in varying degrees of wilting or leaf sagging. It is generally suggested that from early spring to early autumn, the plant can be treated with rotten bean cake water or alum fertilizer once a month, or a comprehensive compound fertilizer with nitrogen, phosphorus and potassium can be used to meet its growth needs. At the end of autumn and the beginning of winter, when the temperature dropped, the plants were applied phosphorus and potassium fertilizer twice, each time at an interval of about half a month, in order to enhance the ability of the tree to resist disease and cold.
