The leaves of the peacock arrowroot are yellow:
Peacock arrowroot prefers semi-shade, does not tolerate direct sunlight, and adapts to grow in a warm and humid environment. Too much water, too little sunlight, too much or too little fertilizer will cause yellowing of leaves, but the yellowing situation is different, and the causes should be carefully observed and analyzed, and corrected. Aqua:
The young leaves are dark yellow and dull, the old leaves have no obvious changes, the branches are small yellow-green, and the new shoots are shrunk and not long, indicating excessive watering. Depot the flowers, put them in a ventilated and cool shade, and dry the soil ball before putting them back into the pot.
Dry yellow: the yellow of lack of water is not the same as the yellow of more water, the yellow of lack of water is the withering and dry leaf tips or edges, and the old leaves are withered and yellow from the bottom to the top, but the growth of new leaves is relatively normal. Pay attention to watering when watering enough, water thoroughly.
Burning yellow: strong sunlight directly shines on some shade-loving flowers (such as spider plant, peacock arrowroot, hosta, etc.), which is easy to cause the leaf tips and leaf edges of flowers to wither, and the sunny part of the leaves appears yellow spots. Move to the pubic area.
Lack of light yellow: If the leaves are shaded for a long time, the leaves cannot get enough sunlight to form chlorophyll, and the whole leaves turn yellow and then fall off, and the disease can be avoided by supplementing light.
Fat yellow: the yellowing of flowers caused by excessive fertilization or excessive concentration is manifested in the dry brown appearance at the top of the new leaves, the general leaf surface is thick and dull, and the concave and convex are not stretched, and the old leaves are scorched and yellow. Fertilization should be stopped immediately, and part of the fertilizer should be washed with plenty of washing in severe cases.
Lack of fat yellow: It is manifested in the color of young leaves becoming lighter, yellow or light green, while old leaves are more normal or gradually turning from green to yellow. Check the potting soil, if there is a dry knot, the soil should be changed, the thin fertilizer should be applied frequently and some alum water should be poured in a timely manner ("peacock arrowroot" is a fertilizer that should be applied to foliage plants with nitrogen fertilizer).
Pest control. There are fewer diseases and insect pests of peacock arrowroot, but if the ventilation is poor and the air is dry, scale insects will also occur, and imidacloprid series drugs should be sprayed for control.
Leaf spot disease yellow-brown, in the early stage of the disease near the edge of the leaf or leaf ** formation of small yellow spots, and gradually expand, the color deepens, turn yellow-brown, there is a more obvious halo around the lesion, with the expansion of the lesion, the leaf gradually withered, atrophied, so that it falls off and dies. The causative agent is the spores of the semi-known bacterium Descor. The causes of the disease are high temperature and humidity, poor air circulation, too dense placement of plants, many weeds and rotten leaves in the cultivation environment, excessive application of nitrogen fertilizer, and plant growth.
People with young tissues are prone to the disease. The control method is to strengthen fertilizer and water management, appropriately increase phosphorus and potassium fertilizer, and apply less nitrogen fertilizer to promote the growth of plants and enhance their own resistance. Remove diseased leaves and weeds in time to reduce the source of infection.
The placement of plants is not easy to be too dense, proper ventilation and light transmission, reduce the humidity of the environment, and reduce the incidence of disease. Spray protection at onset. The potions are:
50% carbendazim 600 times to 800 times; or 75% chlorothalonil 600 times to 800 times; 50% mancozeb 500 times to 600 times every 7 to 10 days. The various drugs should work alternately to prevent the bacteria from developing resistance.

The yellow leaves of peacock arrowroot are usually caused by excessive watering, too much sunlight, or improper fertilization.
Peacock arrowroot prefers a semi-shady environment, avoid direct sunlight, and adapt to growing in a warm and humid environment. A certain degree of shade should be given during home maintenance, and the temperature should be controlled to make 12 29, and the temperature should be maintained at 16 18 in winter. Spring and summer are the peak growing seasons, which require greater air humidity and can be sprayed in time.
Peacock arrowroot does not have high requirements for soil, ordinary loose soil is enough, but it is required to be moderately moist, and fertilizer is applied once every 2 weeks during the growing season. In winter, the soil can be slightly drier and cooler, and the frequency of fertilization is reduced. Peacock arrowroot can be propagated by rooting, cuttings and other methods, which is simple to operate and has a high survival rate.

Symptoms Peacock arrowroot likes a semi-shady environment, strong sunlight shines directly on the shade-loving peacock arrowroot, and the servant is easy to cause the leaf tips and leaf margins of flowers to wither, and the sunrise part will appear yellow spots.
Solution: You don't need to deal with it too much, just move it to a cool place in time. If the yellowing is severe, remove the leaves directly.
Symptoms If the leaves are shaded for a long time, the leaves do not get enough sunlight to form chlorophyll, and the nutrients for the growth of the plant themselves are insufficient, and the whole leaves turn yellow and then fall off.
Solution Supplemental light can avoid yellowing of leaves, but the process of supplemental light should be gradual and pay attention to avoid strong light.
Symptoms The young leaves are dark yellow and dull, and there is no obvious change in the old leaves, but the branches are small yellow-green, and the new shoots are shrunk and not long, indicating excessive watering.
Solution If the potting soil is in a wet state, you can depot the plant, dry the potting soil in the sun, replant it after the potting soil dries, and then pay attention to the appropriate amount of watering.
Symptoms Leaf tips or edges are withered and dry, and old leaves are yellow and fall off from bottom to top, but new leaves grow normally.
Solution: Pay attention to watering when watering enough, water thoroughly. If it is not clear whether it is watered enough, you can use a bamboo skewer to insert it into the soil, and when there is more soil on the surface of the bamboo skewer, it indicates that the potting soil is wet and does not need to be watered, on the contrary, it is necessary to replenish water in time.
Symptoms Excessive fertilization or excessive concentration or application of unrotted fertilizer, resulting in yellowing of flower leaves, manifested in dry brown at the top of new leaves, generally thick and dull leaf surface, and uneven and uneven, old leaves are scorched and peeled off.
Solution Fertilization should be stopped immediately, if the potted fertilizer is serious, it can be diluted by watering, or the plant can be directly depotted, mixed with new soil, and the fertilizer can be diluted.
Symptoms Peacock arrowroot lack of fertilizer will inevitably grow poorly. It is manifested as the color of young leaves becoming lighter, yellow or light green, while old leaves are more normal or gradually turning from green to yellow.
Solution Check the potting soil, if there is a dry knot phenomenon, the soil should be replaced, usually thin fertilizer is applied frequently and some alum water is poured in a timely manner, and nitrogen fertilizer-based fertilizer is applied.

After the leaves of the peacock arrowroot turn yellow and wither, use sharp scissors to cut off the yellowed branches. In addition, during the cultivation of peacock arrowroot, it is necessary to regularly spray water mist around it to moisten it. During the daily maintenance of peacock arrowroot, the ambient temperature is controlled at 20, and the insulation treatment is carried out in winter.
Every time you apply fertilizer (or trim fertilizer), dilute the fertilizer with water before watering to avoid drying and yellowing of the leaves of the peacock arrowroot.
Prune the leaves. After the leaves of the peacock arrowroot turn yellow and wilt, the yellow and dry parts of the leaves should be properly pruned. Pruning the dry part of the leaf can keep the green color of the leaf and avoid the continuous spread of the dry part, resulting in a dry state of the entire leaf.
Water properly. After the leaves of the peacock arrowroot are dried, in addition to pruning the dry parts, it is also necessary to adjust the watering frequency leakage and watering method. If the leaves are curled and dry due to too little watering, hydrate immediately.
In the daily maintenance process of peacock arrowroot, it is necessary to frequently use a sprinkler can to sprinkle water around the leaves to avoid the phenomenon of dead leaves again.
Control the temperature. Peacock arrowroot is suitable for growing in a warm environment. If the temperature is too low, it will cause frostbite on the roots of A. mabacock, resulting in curling and drying of A. mazard leaves. Therefore, in winter, the peacock arrowroot can be moved indoors for maintenance to ensure the ventilation of the environment.
Proper fertilization. The curled dry leaves of the peacock arrowroot can also be caused by over-fertilization. Excessive fertilization will lead to excess nutrients in the soil, resulting in fertilizer damage, so that the roots of peacock arrowroot can not absorb nutrients normally, unable to transport nutrients to the leaves, resulting in curling of peacock arrowroot leaves.
At this point, water can be poured into the soil to dilute the fertilizer in the soil. Dilute the fertilizer in the soil.

Depending on the characteristics of its occurrence, there are the following situations:
One is water yellow. Caused by over-frequent watering, it is characterized by no obvious change in old leaves and yellowing of young leaves; This should be done with immediate water control;
The second is dry yellow. Caused by lack of water and drought, it is characterized by the first yellow leaves from the bottom up, if the lack of water for a long time, the whole plant will be yellow, and even die, should be watered in time;
The third is fat yellow. Caused by excessive fertilization or high concentration; It is characterized by thick, shiny, and uneven young leaves; Fertilizer, cultivation and watering should be controlled;
Fourth, hungry yellow. It is caused by insufficient fertilizer, low concentration of fertilizer, and long fertilization interval; It is characterized by the first yellow of young leaves and young stems, and if you do not fertilize in time after seeing this phenomenon, it will also cause the whole plant yellow leaves or even die; For flowers lacking fertilizer, avoid applying a large amount of thick seed manure at a time, so as not to cause root burning;
Fifth, iron deficiency yellow leaves. Due to the great change of soil fertility and renting capacity conditions in greenhouses, woody flowers in greenhouses often appear yellow leaves, which are characterized by obvious young leaves, light old leaves, yellow mesophyll, green leaf veins, and the formation of a typical network. It can be solved by applying ferrous sulfate aqueous solution, and the method is: 7 parts of cake fertilizer, 5 parts of ferrous sulfate, and 200 parts of water are prepared into multiple liquid water.
