Too high temperature will cause yellow leaves and leaves to fall. Many friends don't pay attention to the comfort of the plants when they put the emerald tree plants. They usually put them close to the air conditioner and the computer. Some friends directly put the plants at the air outlet of the computer, so that the plants will be very uncomfortable, and will not grow well.
Build a shade shed for emerald tree, increase the frequency of water spraying, or put emerald tree in a cool and ventilated place with sparse shade. Remember not to put it in the air outlet of the computer. In addition, if the temperature is lower than 8 ℃, there will be a risk of frostbite at first! The temperature must not be too low!
Too much or too little light is easy to cause yellow leaves and falling leaves. Happiness tree is a positive plant. It needs full sunshine to avoid the sunshine in summer.
Put the emerald tree on the balcony and other places that can be exposed to the sun, but pay attention to the fact that the emerald tree likes the light, but doesn't like to be exposed to the sun.
Too little water causes yellow leaves to fall. Emerald tree likes wet soil and cultivation environment.
Too much watering will also cause water accumulation, which will make the root of emerald tree not breathe well and cause yellow leaves.
Pay attention to watering. Don't wait for the soil to be completely dry before watering. If watering, it should be fully watered at one time. It can't just be wet on the top and dry on the bottom. The principle is not to dry or pour, but to pour it thoroughly.
At the same time, we should also pay attention to the indoor air humidity. We can spray water around the emerald tree properly to increase the indoor air humidity.
Can often spray plants with water to maintain their beautiful appearance, but also to increase environmental humidity.
The air in the room is too dry, the ventilation is poor, and the leaves will also have dry tip phenomenon.
Increase indoor ventilation, increase indoor humidity. Let the leaves of emerald tree breathe more smoothly.
If the amount of fertilizer is too large, it is easy to cause seedling burning and plant yellowing.
At the same time, if the fertilization is too little, the leaves will turn yellow due to lack of nutrition.
If fertilization is too much, you can dilute the fertility of the basin soil with water, but pay attention not to cause water accumulation.
To solve the problem of lack of nutrition, we can appropriately apply some compound fertilizer to the emerald tree, but we must not say too much, too much, too many important things three times.
This belongs to the normal growth range of plants. Happiness tree is constantly metabolizing, with old and withered leaves turning yellow and dying, and new leaves growing out to continue growing. In this case, only the yellow leaves can be cut off without special maintenance.
In the high temperature environment, emerald tree is easy to be infected with leaf spot disease. After infected with this disease, the leaves will also turn yellow.
During the cultivation of emerald trees, ventilation and light transmission should be strengthened to avoid long-term stagnation of leaf surface. When a small amount of diseased leaves are found, they shall be removed and burned in time, and 50% carbendazim wettable powder 600 times liquid shall be sprayed regularly, once a half month, three to four times in a row.
Family potted plants, a small number of individual plants on the leaves of the disease spots, can be applied to the cream.
The common pests of emerald tree are scale insects, mites, aphids and so on. If they are infected with pests, they will cause yellow leaves.
Before the occurrence of pests, we should strengthen the ventilation and light transmission, pay attention to the temperature and humidity of the growth environment of emerald trees, and if the pests have occurred, we should spray insecticides in time at the early stage of the occurrence to kill the danger in the cradle.
