The reason why the powder leaves are yellow is the cultivation method of hydroponic powder palm.

Some owners who will breed the pink palm sometimes see the pink palm in the home turn yellow, but they don't know what caused it, and they don't know how to deal with it. Today, the editor came to tell you that in fact, there is no need to panic in this situation, it is caused by lack of light. Let's learn how to prevent and cure it.

Analysis of the causes of yellowing of pink palm leaves and treatment methods:

First, improper lighting: long-term shelter placed under cover, the leaves can not carry out photosynthesis lack of nutrients, the leaves will gradually turn yellow, if direct sunlight, especially in summer, when the sun is fierce, the leaves will burn and cause the leaves to scorch and yellowed.

Solution: attention should be paid to light during daily management, with semi-overcast or scattered light, and full-yang irradiation in winter.

Second, too much watering: the young leaves on the top of the pink palm are yellowish, the old leaves are also gradually yellowing, and the new shoots are shrinking. This is due to long rain or too much watering, too wet in the basin, lack of oxygen in the soil, and root rot.

Solution: should often loosen the soil, control watering, avoid heavy rain spray.

Third, long-term water shortage: the leaf color on the top of the pink palm is normal, and the lower leaves gradually dry yellow and fall off upward. This is due to the fact that the pan soil is too full or watered for a long time, resulting in the aging of the branches of the lower leaves.

Solution: should be properly watered to keep the soil moist.

Fourth, long-term lack of fertilizer: the pink palm leaves are thin and yellow, which is due to the fact that the big pots of flowers are small or have not been changed for a long time, soil change and lack of fertilizer.

Solution: should gradually increase water and fertilizer, timely change the basin.

Fifth, excessive fertilization: the pink palm leaves appear concave and convex, the new leaves are thick, and the old leaves are gradually yellow.

Solution: should be frequently watered, suspend fertilization, the pot can be sprinkled with vegetable seeds, after emergence, pull out, in order to consume fertilizer in the basin, so that flowers and trees return to normal growth.

VI. Diseases and insect pests

Observe carefully to see if there are any red spiders behind the leaves of the pink palm plant, and if so, see if they are brought by newly bought flowers, or the flowers at home are born because of poor ventilation. After finding out the cause, it is also easy to pay attention! If no insects are found in the observation, it is leaf yellow disease caused by poor ventilation. Pay attention to ventilation and it can be improved.

Culture methods and matters needing attention of hydroponic powder palm

1. Dig the potted pink palm out of the soil, cut off the rotten roots, hairy roots and old leaves, wash it with clean water, disinfect it in potassium permanganate solution, and then wash the pink palm with clean water. If you use transparent glassware to hydroponically cultivate powder palms, it is best to cover the glass with a black plastic bag to prevent bright light. Cover it with a transparent convenient bag (heat preservation and moisturizing). Put it in a place where the light is scattered and the temperature is kept above 10 degrees.

2. During the domestication of hydroponic powder palm, it is necessary to change water frequently, once every three days in the first half of the month and once a week in the second half of the month. Every time the water is changed, the nutrient solution should be added, and the nutrient solution should be specially used for hydroponic flowers. After a month, new roots will grow, and the new roots will be relatively adapted to the aquatic environment. The leaves began to sprout.

3. The powder palm is hydroponically cultured in the basin. Hydroponic powder palm flowerpots would be better if they were translucent. Carefully put the powder palm root into a water culture basket, which can be filled with river stone or ceramsite to fix the position of the plant. It is better to add half of the water or 2 stroke 3, so that the roots that are not submerged can be breathed from the air.

4. The domesticated hydroponic powder palm can change the water according to the actual situation, and the water should be changed when there are more impurities in the water, and the hydroponic flowerpot should be cleaned after a period of time, and the nutrient solution should not be added too frequently, because it will cause the rich nutrition of the water. if the reproduction of microorganisms in the water is accelerated, the oxygen content in the water will drop sharply, which is not conducive to plant growth.

5. If you use a larger flowerpot to cultivate powder palm, you can also raise small fish in the water. Plants and fish can benefit each other and form a scene accordingly. It's killing two birds with one stone.
