The reason for the yellowing of leaves of Guanyin bamboo

Looking at the species called Guanyin bamboo on the Internet, there are not only differences in appearance, but also their own strengths. For novice flower lovers, hydroponic flowers seem to be easier to raise, and some may be so, but many friends always encounter the problem of yellowing leaves when cultivating Guanyin bamboo. Now we will briefly explain the solution to the yellowing leaves of Guanyin bamboo in the following picture.

The reasons for the yellow leaves of Guanyin bamboo and its solutions:

Water yellow: the young leaves are dark yellow and dull, the old leaves have no obvious change, the branches are small and yellow-green, and the new shoots are not long, indicating that they are overwatered. Remove the flowers from the pot and place them in a ventilated, cool, self-drying soil mass and then put them back into the basin.

Dry yellow: lack of water yellow and water-rich yellow, lack of water yellow for leaf tips or edges withered, dry, old leaves withered and yellow shedding from bottom to top, but the growth of new leaves is relatively normal. Pay attention to watering enough and thoroughly.

Burning yellow: strong sunlight shines directly on some shade-loving flowers (such as hanging orchids, hairpins, etc.), which can easily cause withered leaf tips and edges, and macula in the sunny part of the leaves. Just move to the shade.

Lack of light and yellow: put in a shady environment for a long time, the leaves can not get enough sunlight, can not form chlorophyll, the whole leaves turn yellow and then fall off, supplementary light can avoid the disease.

Fat yellow: flowers yellowing caused by excessive fertilization or excessive concentration, showing dry brown at the tip of new leaves, thick and dull leaves, and concave and convex, and old leaves are scorched yellow and fall off. Fertilizer should be stopped immediately and some fertilizers should be washed with a large amount of washing. Causes of yellowing of Phyllostachys pubescens leaves and its solution

Phoenix tail bamboo everyone likes, planting Phoenix tail bamboo is to bring fengshui and wealth to the family. The culture method of Phyllostachys pubescens needs to be treated cautiously. What if we find that the leaves of Phyllostachys pubescens are yellow in the planting process? Let's talk about the culture information of Phyllostachys pubescens.

Causes of yellowing of Phyllostachys pubescens leaves and its solution

The main results are as follows: (1) too much watering, the basin soil is too wet for a long time, resulting in lack of oxygen in the soil, causing part of the fibrous roots to rot, hindering normal respiration and absorption of water and nutrients, causing leaves to turn yellow and fall off. After the injury, the young leaves turn pale yellow, and then the old leaves gradually turn yellow. watering should be controlled immediately, fertilization should be suspended, and the soil should be often loosened to make the soil well ventilated.

(2) drought and dehydration. Flower cultivation leakage watering or long-term watering half waist water (that is, upper wet and lower dry) will affect nutrient absorption, and it is also easy to cause dull and dull leaves and drooping leaves. First, the lower old leaves aged, and gradually withered and yellowed off from the bottom up. At this time, a small amount of watering and spraying is needed to gradually recover and then turn to normal watering.

(3) to lose weight for a long time. There is no application of ammonia fertilizer or no change of soil for a long time, and there is a lack of nitrogen and other nutrients in the soil, resulting in thin branches and leaves and thin and yellow leaves. It is necessary to pour the pot in time and gradually apply rarefied mature liquid fertilizer or compound flower fertilizer into new loose and fertile culture soil.

(4) excessive fertilization. If you fertilize too much, the new leaves will be thick and uneven, and the dry tips of the old leaves will fall off. You should immediately stop fertilization and increase the amount of water to make the fertilizer flow out from the drainage hole at the bottom of the basin, or immediately pour the pot, rinse the soil block with water and then plant it again into the basin.

(5) hot and high temperature. In summer, if you put cool flowers (such as cyclamen, Golden Bell upside down, four Seasons Begonia) in a high temperature place to let the strong light shine directly, it is very easy to cause the young leaf tip and leaf edge to scorch, or the leaf yellow to fall off. Move to a well-ventilated shady place in time.

(6) excessive shading. If the sun-loving flowers are kept in shade or lack of light for a long time, it will cause the branches and leaves to grow, the leaves are thin and yellow, and they do not blossom or rarely bloom. Be careful to move the flowerpot to the sunny place

(7) soil and water is alkaline. There are more saline and alkali in soil and water in most areas of northern China, and flowers with acid-like soil are planted, such as rhododendron, camellia, Michelia, gardenia, orchid, magnolia, sweet-scented osmanthus and so on. Due to the lack of soluble iron and other elements that can be absorbed by the soil, the leaves will gradually turn yellow. Acid soil should be selected when planting, and alum fertilizer and water should be often watered during the growth period.

(8) whether it is airtight or not. If too much nitrogen fertilizer is applied, the branches and leaves will grow luxuriantly, coupled with the long-term unpruned, resulting in insufficient light in the inner chamber branches and leaves, which is easy to cause the leaves to yellowing and falling off. Reasonable fertilization should be applied and pruning should be strengthened to make it ventilated and transparent.

(9) dry air. When the indoor air is too dry, some flowers that like the humid environment, such as hanging orchids and orchids, often appear leaf tip dryness or leaf edge scorching and so on. Attention should be paid to water spraying, plastic film cover and other methods to increase air humidity.

(10) improper temperature. If the room temperature is too low in winter, the flowers are often vulnerable to cold damage, which leads to the yellowing of the leaves and death in severe cases. If the room temperature is too high, the transpiration of the plant is too high, and the root water and nutrients are in short supply, the leaves will turn yellow. Please pay attention to adjust the room temperature in time.

(11) the soil is sour. It is easy to lose acid and magnesium in southern red loam. planting flowers and trees with alkali-tolerant or mute soil, such as oleander, yellow poplar, Yingchun, etc., are often prone to green and yellowing between the veins of old leaves. Can apply calcium magnesium phosphate fertilizer or spray magnesium sulfate solution.

(12) pests and diseases. Leaf spot disease caused by fungi and other bacteria is easy to cause local necrosis of the leaves, yellow spots or patches appear, the whole leaves wither and fall off seriously, yellow and green mottle appears on the leaves after being infected by mosaic virus, and damaged by shell insects, red spiders and so on, the leaves will also become local yellow, or even the whole leaves will wither and fall off. All should be sprayed and prevented in time.

(13) strong sexual stimulation. The use of too high concentration of pesticides in the control of diseases and insect pests, or being polluted by toxic gases in the atmosphere, or suddenly watering cold water when the temperature is high, are easy to cause local yellowing and scorching of the leaf tip or leaf surface, or even death of the whole plant.

Causes and Solutions of yellowing leaves of Guanyin Bamboo

Throughout the species called Guanyin bamboo on the Internet, there are not only differences in appearance, but also their own advantages; for novice flower lovers, hydroponic flowers seem to be more relaxed and easy to raise, and some may be so, but many friends always encounter the problem of yellowing leaves when they cultivate Guanyin bamboo. Now we will briefly explain the solution to the yellowing leaves of Guanyin bamboo in the following picture.

The reasons for the yellow leaves of Guanyin bamboo and its solutions:

Water yellow: the young leaves are dark yellow and dull, the old leaves have no obvious change, the branches are small and yellow-green, and the new shoots are not long, indicating that they are overwatered. Remove the flowers from the pot and place them in a ventilated, cool, self-drying soil mass and then put them back into the basin.

Dry yellow: lack of water yellow is different from water-rich yellow, water-deficient yellow is leaf tip or edge withered, dry, old leaves withered and yellow shedding from bottom to top, but the growth of new leaves is relatively normal. Pay attention to watering enough and thoroughly.

Burning yellow: the strong sun shines directly on some shade-loving flowers (such as hanging orchids, hairpins, etc.), which can easily cause the withering of the leaves' tips and edges, and macula in the sunny part of the leaves. Just move to the shade.

Lack of light and yellow: put in a shady environment for a long time, the leaves can not get enough sunlight, can not form chlorophyll, the whole leaves turn yellow and then fall off, supplementary light can avoid the disease.

Fat yellow: flowers yellowing caused by excessive fertilization or excessive concentration, showing dry brown at the tip of new leaves, generally thick and dull, concave and convex, and old leaves are scorched yellow and shedding. Fertilizer should be stopped immediately and some fertilizers should be washed with a large amount of washing.

Lack of fat yellow: the color of the young leaves becomes lighter, yellow or light green, while the old leaves are more normal or gradually change from green to yellow. Check the basin soil, if there is a dry phenomenon should change the soil, usually apply thin fertilizer frequently and timely sprinkle some alum (Guanyin bamboo is Guanyin bamboo should be nitrogen-based fertilizer).

Cut root yellow: do not cut off the root in winter, so that it can not absorb water, the leaves will naturally turn yellow.

When raising Guanyin bamboo, you must pay attention to the common sense:

1. Peeling leaves: peel the leaves from the base of the cuttings to the mouth of the bottle before entering the bottle, not just to remove or cut off the leaves, but also to peel off the leaves attached to the stem. It can only be said to be stripped clean until you see a circle of bamboo knots exposed and its bluish-yellow skin, so that when changing water later, the stem will not have that slippery feeling, and the water will not stink easily. After peeling off the leaves, use a sharp knife to cut the base into an oblique notch, the incision should be smooth, in order to absorb water and nutrients.

2. Use water: water is used to raise Guanyin bamboo. Don't change all the water. Retain 1 / 3 of the water. Add two-thirds of the fresh water.

3, the depth of the water: do not put the water too deep, so as not to grow too much, as long as the height of the vase of 1 hand 2 or 3 hand 5 is fine (the construction is maintained with a transparent vase so that you can observe the growth of the roots and know the height of the water).

4. Display: do not put the Quan Yin bamboo in the place where the air conditioner is often blown, as this will make the leaves turn yellow.

5. Humidity: properly spraying water to increase air humidity to prevent dry leaves and yellow leaves.
