The reason why the white palm leaves slowly turn yellow and how to deal with it. The general horticulturist will not tell you the secret.

Thank you for the invitation. There are many reasons for the yellowing of white palm leaves. I have repeatedly stressed that taking pictures can be used as a reference to facilitate the horticulturist to give you more direct maintenance advice or describe more content. Pot size, home temperature and humidity, coordinates, southern and northern climate is different, maintenance methods are also slightly different, especially in winter, the north has heating indoor, a lot of maintenance matters needing attention. In short, the more descriptions, the more pictures, the more convenient it is for the gardener to diagnose diseases and insect pests on your flowers.

According to the maintenance experience, about several situations are analyzed, and the subject corresponds to each other to find out the answer.

Just cut, be careful not to spray water and keep the wound dry. Avoid decay.

2, the disease causes the leaves of white palm to turn yellow slowly. The flowers turn yellow and wilt before they fully bloom, and there is also the phenomenon of rot, indicating that plants are infected with germs.

Solution:

A can be treated with medication. Choose fungicides, chlorothalonil or carbendazim or methyl topiramate or amiceda or mancozeb. Spray 2-3 times in a row, once every 7-10 days. If it doesn't get better, try switching to agricultural streptomycin. Because there is no picture of the disease, the symptoms are not clear, and it is not possible to judge whether the disease is caused by fungi or bacteria. The subject had to try to come by himself. Spray stems and leaves and irrigate roots together.

b. The climate at home is suitable, about 15 degrees above, you can consider changing soil and replanting. The soil is infected with germs, and the operation of changing soil can reduce the disease. Go to the flower market to buy peat soil (coconut bran soil, pine needle soil, rotten leaf soil), perlite, vermiculite according to 3:1:1. Pay attention to check the root system when changing the basin, cut off the diseased and rotten roots, dry them in a natural ventilation place for a while, spray some fungicides, and replant. The original old flowerpot is washed with flowing water and sterilized in the sun.

3. Other points for attention:

A, the radiator in the north, the air outlet of the air conditioner, the floor is warm, pad the foot tray. Prevent drying plants and speed up the yellowing of flowers.

B, spray water, choose spray. Don't spray too much, the leaves hold water, which will lead to rot and accelerate yellowing.

C, pay attention to avoid Rain Water weather outside in the south.

D, pay attention to low temperature freezing injury, and do not expose yourself to high temperature.

E, pay attention to insect pests, red spiders, aphids and other hazards.
