What is the latest blackening of the leaves of the money tree?
Artemisia mandshurica is a very common ornamental plant in our daily life, and its planting area is very extensive in our country. The ornamental value of the money tree is very high, so it is also welcomed by many people. However, when planting money trees, there is often the phenomenon that the leaves of money trees are blackened, so how is the leaves of money trees blackened? The following editor will give you a brief introduction, let's have a look!
1. Overwatering
The leaves of the tree are very thick, the water content is relatively high, and the underground stem of the tree is also very rich in water, and its drought tolerance is very strong. Therefore, when we are protecting the money tree, we should be careful not to water too much, and we should not water it too frequently. Over a long period of time, the soil is easy to produce stagnant water, resulting in blocked root respiration, resulting in blackening of leaves. At this time, stop watering in time, then immediately ventilate and dry the water. Wait until the plant gradually recovered, and then reduce the number of watering, to see dry and wet as the watering principle.
2. Excessive illumination
The money tree is actually a plant that likes to grow in an environment with plenty of light. But even so, its resistance to strong light is relatively poor. Never let the money tree be exposed to the sun for a long time, for a long time, it will cause the metabolism of the money tree to be blocked, and the leaves will gradually appear yellow and black. Especially in summer, the light is stronger. If the leaves turn yellow because of the strong light, cut off the black leaves and yellow leaves in time, and then move them to a place with soft light for management. In the summer, we must pay attention to do a good job of shading, do not be exposed to the sun.
3. Temperature discomfort
The tree likes to grow in a warm environment, and its ability to withstand high temperature is also strong, but it is not cold-resistant. Therefore, in winter, we must pay attention to do a good job of cold prevention and heat preservation. If the temperature is not controlled properly in the low temperature environment in winter, then the plant is extremely vulnerable to freezing damage. After freezing injury, there will be yellow leaves and black leaves. So in winter, we have to move the plant indoors. The lowest temperature should be kept above 10 degrees to avoid frostbite, ensure that the tree can survive the winter safely, grow normally, and reduce the blackening of leaves.
4. Causes of diseases and insect pests
Diseases and insect pests are also one of the main reasons for the blackening of the leaves of money trees. When raising the money tree, if the environment is uncomfortable, then the plant is very easy to be infected with diseases and insect pests, and the main harm objects of many diseases and insect pests are mainly leaves. After the leaves are damaged, they will naturally blacken. For the leaves blackened by diseases and insect pests, we should cut them off in time to prevent the disease from spreading. Then symptomatic medication is carried out according to specific diseases and insect pests, and if it is a soil infection, then the new soil should be replaced in time.
The above is a brief introduction to the blackening of the leaves of the money tree. That's all for today's introduction. This article is for reference only. I hope it can help you all.
