The Fortune Tree, also known as Malabarah, means that raising this tree has a fortune, so many people are willing to plant a tree at home or in the company. At this fast-paced life, not everyone has that much time to take care of these plants, so it is easy to get sick, the leaves appear yellow and other symptoms, and Xiao Bian today to learn fiscal leaves hair with yellow How to do it.
In addition to the yellowing of the leaves of the money tree, due to excessive watering, it may be caused by the following reasons:
1) Long-term de-fertilization, no long-term application of nitrogen fertilizer or no change of pots and water, lack of nutrients such as nitrogen in water, resulting in thin leaves and thin yellow leaves. Need to be replaced with new culture water in a timely manner and gradually increase the use of thin rotten liquid fertilizer or compound fertilizer.
2) Excessive fertilization, too much fertilization will lead to new leaf hypertrophy, and more uneven, old leaves dry Jiao Huang fall off, should immediately stop the fertilization, increase the amount of water exchange, so that the loss of fertilizer, or immediately down the pot, rinse with water after the ball Then replant into the basin.
3) Hot and high temperature, if the flowers are placed in a hot place for direct sunlight, it is easy to cause the young leaves tip and leaf margin coking, or leaves yellow off. Move to a well-ventilated shade in time.
4) Excessive shade. If the flowers are kept in shade or in poor light for a long period of time, the leaves will be yellow.
5) Alkaline water and soil, because the water lacks soluble iron and other elements that can be absorbed by it, the leaves will gradually turn yellow. Acid water and soil are used for planting, and fertilizer and water are often poured during growth.
6) The airtightness is not ventilated. If too much nitrogen fertilizer is applied, the branches and leaves grow into luxuriant growth, and long-term untrimmed, resulting in insufficient light of the inner leaf, which may cause the yellow leaves to fall off. Fertilizer should be applied properly and trimmed to make it light and airy.
7) When the air is dry and the indoor air is excessively dry, the flowers tend to have dry tips or leaf scorch. Care should be taken to increase air humidity by spraying water, plastic film cover, etc.
8) The temperature is not appropriate, the room temperature in winter is too low, and the flowers are subjected to cold damage. As a result, the leaves are yellow, and they die when they are severely yellow. If the room temperature is too high, the transpiration of the plant is excessive, and the supply of water nutrients in the root will be in short supply, and the leaves will also turn yellow. Please pay attention to adjust the room temperature in time.
9) Diseases and insect pests, leaf spot caused by fungi and other pathogens, easy to make partial leaf necrosis, yellow spots or plaques, severe yellow leaves off the whole leaf, after the mosaic virus appeared yellow green leaves Embeded mottled; suffer from scale insects, red spiders, etc.
10) Strong stimuli, the use of excessive pesticide concentrations in the prevention and control of pests and diseases, or contamination by toxic gases in the atmosphere, or sudden watering of cold water when the temperature is high, can easily cause yellow tipping and dryness of the tip or leaves, or even the death of whole plants. Therefore, German Yoko suggested that we should pay attention to the rational use of pesticides and try to eliminate air pollution sources.
If the money tree has no leaves, then you simply cut the top of the tree underneath the last bud. In the spring, the new leaves it grows will grow neatly, just like you just bought it. In the same way, the above is about several reasons why the leaves of Pachira fulgens have yellowed and withered.
