What s the matter with the white and spotted plant unicorn?

The whitish and spotted appearance of the plant unicorn may be caused by the following reasons:

1.The unicorn palm itself contains a toxic white emulsion, if these white emulsions come out accidentally, and after a long period of wind and sun exposure, it may cause small white spots on the leaf surface.

2.The unicorn palm may suffer from worm disease, which is generally a scale worm, which can secrete a white waxy shell, which will cause the leaf surface to look like small white spots, and if you touch it with your hands, it will feel very sticky and sticky.

If there are scale insects, a small amount can be artificially treated, if the number is large, you need to use a toothbrush to brush the insects off the surface of the leaf first, and then use a special insecticide to spray, but do not let the insecticide soak the potting soil, otherwise the insects will grow again. When cleaning white spots and sticky substances on the foliar surface, wear gloves and masks to prevent toxic and harmful substances from coming into contact with them.

The plant unicorn is whitish and a little spotted, which means that he has a disease like um, a spider, and this spider's disease is indeed a little whitish for his kind of unicorn warlock. This kind of plug white spot is a small bug, and this little bug must be used. That kind of medicine killed him, and finally it would be good to keep it in a ventilated place for an extra month.

There are two reasons for the sticky or white spots on the leaves of the unicorn palm, one is that the unicorn palm itself has a toxic substance white emulsion, if these white emulsions come out accidentally, and after a long time of wind and sun exposure, it may cause the leaf hair to be sticky with small white spots.

The other is that the unicorn palm suffers from worm disease, which is generally a scale worm, which can secrete a white waxy shell, which will cause the leaf surface to look like a small white spot, if you touch it with your hand, it will feel very sticky and sticky.

If there are scale insects, a small amount can be artificially treated, if the number is large, you need to use a toothbrush to brush the insects off the surface of the leaf first, and then use a special insecticide to spray, but do not let the insecticide soak the potting soil, otherwise the insects will grow again. In the later stage, foliar sprays of pica foliar fertilizer were applied to prevent the occurrence of diseases.

Summary. Hello, dear, I am glad to answer for you: the jade unicorn has dark spots, and the cultivation method is related to the environment, and the jade unicorn likes drainage, well-ventilated soil. Potted plants should be planted on well-drained sandy soil, not too fertilized.

Hello, dear, I am happy to answer for you: the jade unicorn has black spots, the cultivation method is related to the environment, the jade unicorn likes to drain, Li disturbs the soil with good ventilation. Potted plants should be quietly disturbed and drained well, and should not be too fat.

Pro, the amount of watering should be less, the plant grows and returns to the ancestors quickly, so don't worry, apply a thin liquid fertilizer once a month, and the potted soil can be dried and broken with fish pond mud and mixed with 20% sand to prepare; Or mix 4 parts of vegetable garden hall soil, 4 parts of humus soil and 2 parts of sand. After planting in pots, water the roots. In the future, depending on the actual situation, water every two or three days, the amount of watering can be less than the general broad-leaved flowers, but slightly more than the leafless cactus flowers.

The yellowing of your plant's leaves can be caused by overwatering, malnutrition, or low temperatures. You can determine the cause based on your specific situation.

Summer and autumn are the peak growing seasons for unicorn palms. It likes the sun, but avoids exposure to the sun, and can be shaded with bamboo curtains. Watering should be less than not more, and grasp the principle of seeing dry and wet.

In winter, when the temperature is low, watering should be controlled. You can apply thin soybean cake water or sesame sauce residue water once a month. The unicorn palm is not cold-tolerant and is generally moved indoors in mid-October before the frost falls.

The room temperature is kept above 15, the leaves do not turn yellow, and the leaves dry up and fall off below 12. If the room temperature is above 6, the potting soil is relatively dry, and the unicorn palm will not freeze and will still produce new leaves the next year. Repot 1 time every 1 2 years.

Yellowing and defoliation of unicorn palm leaves is extremely common, and the cause may be root malnutrition. The following four are the causes of root malnutrition: insufficient water, too much water, lack of fertilizer, and too much fertilizer. It should be noted that if the soil is not dry, do not water.

White spots on the leaves are downy mildew, and the cause is the same as above.

This kind of flying small white worm is called whitefly, also known as small white moth, adults and nymphs can harm more than 200 kinds of Fuso and other flowers and trees, and there are widespread occurrences throughout the country. Its adults and nymphs, parasitic on the back of the leaf, pierce into the mesophyll to suck its sap, make the leaf curled, green and yellow, and even dry and fall off, and can discharge a large amount of honeydew, pollute the stems and leaves, cause serious coal stain disease, affect the growth and flowering of the plant. It occurs most seriously in conditions of poor light, high humidity, high temperatures, poor ventilation, and crowded plants, especially indoors in winter.

Prevention and control methods: under the condition of home cultivation, when the adults are flying around, you can try to spray the mosquito net to knock down the adults in one fell swoop, and then gently wipe off the mold layer on it with a damp cloth, strengthen the management of water and fertilizer, and the plants can quickly recover their vitality.
