What to do if the leaves of the anchovy bamboo are yellow and dry

The yellowing and dryness of the leaves of the anchovy bamboo should be solved according to the specific yellowing colorWater yellow: the young leaves of Anchovy bamboo have no light and no change in the old leaves, and the plants should be replanted after being depotted and dried; Dry yellow: too little watering, the old leaves from top to bottom yellow and fall off, should increase the amount of water, water thoroughly and so on.

1. Performance: water yellow

It is manifested in the young leaves of Anchovy bamboo, the old leaves do not change obviously, the branches are gradually smaller, and the new shoots develop wilted.

Solution: Place the flowers in a dry and ventilated place for maintenance, and wait for them to dry and put them back into the potting soil.

2. Performance: dry yellow

Too little watering will also lead to the phenomenon of yellowing of leaves, too little watering, the edges of the leaves are dry, and the old leaves gradually turn yellow and fall off from top to bottom, but the growth of new leaves is still relatively normal.

Solution: Pay attention to watering more often, just water thoroughly.

3. Performance: burnt yellow

Exposure to strong sunlight can cause yellowing of leaves, which is manifested as leaf tips, dry leaf margins, and color-changing spots on leaf parts.

Solution: Place the burned anchovy bamboo in a cool and dry place.

4. Performance: fat yellow

Excessive fertilization of plants will also cause the phenomenon of yellowing of flowers, which is mainly manifested in the appearance of brown at the top of the leaves of the plant, generally the leaf surface is thick and luster, and uneven, and the old leaves are yellow and falling.

Solution: Stop fertilizing the bamboo, if the disease is severe, you can use clean water to irrigate, and drain the water, gradually reduce the concentration of fertilizer.

The yellowing of the leaves of the anchovy may be caused by water accumulation in the soil, and it is necessary to drain the water in time and reduce the frequency of watering. If the light is too strong and the temperature is too high, you need to avoid direct sunlight and sprinkle water to cool down. If fertilization is improper, it needs to be fertilized scientifically.

If it is caused by pests and diseases, it needs to be sprayed and treated in time and scientifically maintained.

If the light is too strong, it will directly lead to scorched leaves, you can give proper shade, put not so strong light in the living room, and dry air is also one of the main reasons, the seller said that watering once in two or three days means that you will water the soil when it is dry, not dry and not watered, if it goes on like this, the soil is often wet, which will directly lead to rotten roots. Spray the blades, every two to three days, the front and back should be sprayed. It should be placed in a place where the sun is exposed to the sun for a short period of time, but not for a long time.

The leaves have dried up and cannot be preserved by water, so they can grow well since the new leaves.

The leaves of the phoenix are yellow and dry, which is leaf blight.

Leaf blight mostly occurs from the leaf edge and leaf tip, the lesions are irregular from small to large, reddish-brown to gray-brown, the lesions are connected into large blight, the dry area reaches 1 3 to 1 2 of the leaves, and there is a darker band than the lesions at the edge. The boundary between disease and health is clear. It is common in plants and can occur from July to October. The lower leaves of the plant are severely diseased.

High temperature, humidity and poor ventilation are conducive to the occurrence of diseases. The disease is more severe when the plant growth is weak.

The diseased leaves turn yellow at the beginning, and the yellow part gradually turns brown and dies. It extends from local to the whole leaf vein, showing brown to reddish-brown leaf margin lesions, with wavy edges and dark color. The disease-healthy junction is pronounced, and the outer edge sometimes has a shallow yellow band of varying widths and narrowness, and then the lesion gradually extends to the base of the leaf until the whole leaf turns brown to grayish-brown.

This is followed by the appearance of black villi or small black dots on the dorsal or frontal surface of the diseased leaves.

Prevention and control methods. In autumn, the diseased leaves are completely removed and burned intensively to reduce the infection of the following year**.

Strengthen cultivation management and control the occurrence of diseases. The planting land should be well drained, the soil should be fertile, and organic fertilizers and phosphorus and potassium fertilizers should be added. Control the planting density to ventilate and transmit light, reduce foliar moisture, and reduce the chance of infestation. Changed to spraying.

Drip irrigation or running water irrigation to reduce the spread of germs.

During the growing season, in areas with severe disease, from late June to the beginning of the disease, spray once every 10 days or so, and spray several times in a row can effectively prevent and control it. Commonly used agents are 1 to 1 to 100 times Bordeaux solution, 50% tobuzin 500 to 800 times liquid, 50% carbendazim wettable powder 1000 times (or 40% suspension 600 to 800 times, % benzlet 1000 to 1500 times, 65% zebsen 500 times solution, etc., which can be used or alternately.

The tips of the leaves of the anchovy bamboo are yellow and dry, and the solution is as follows:

1. Reduce light.

If the anchovy bamboo is exposed to the sun for a long time, the strong sunlight will burn the leaves, then the leaves will turn yellow, at this time it is necessary to reduce the light, and move it to a cool and ventilated place for maintenance.

2. Stop watering.

If you find that the leaves of the phoenix are yellow, and the new shoots show small leaves, and they are not in a state of going up, then it means that there is too much water in the soil, and you need to stop watering immediately and move it to a cool place slowly.

3. Keep warm.

Winter breeding in the outdoor anchovy bamboo is also easy to appear leaf yellowing phenomenon, mostly due to freezing, the lowest temperature of the anchovy bamboo should not be lower than 0, in the winter of the north it will be placed outdoors is easy to be frostbitten, so to keep warm in time, it is best to move it to indoor maintenance.

4. Stop fertilizing.

Too much fertilization will also cause the leaves of the anchovy bamboo to turn yellow, and the new leaves will also show uneven phenomenon, the old Qiaoqiao leaky branches and leaves will be scorched and yellow and fall off, at this time should stop fertilization in time, if necessary, replace the potting soil, dilute the soil mound at the root of the anchovy bamboo with water, and then replant the Dan seed.

5. Proper ventilation.

Long-term maintenance in the Zen wide disturbance indoor anchovy bamboo will also appear leaf yellowing, if the application of too much nitrogen fertilizer, the branches and leaves grow very luxuriant, but the ventilation is not good, to carry out proper pruning after strengthening ventilation, often open doors and windows for ventilation.
