The temperature is low in winter and the plant is in a dormant state. Watering should be controlled to keep the basin soil moist.

Triangulated plum is a positive flower. Lack of light in the growing season will lead to plant growth weakness, affecting pregnant buds and flowering. Therefore, seedlings in addition to new pots should be placed in the semi-shade all the year round. Winter should be placed in front of the southward window, and the lighting time should not be less than 8 hours, otherwise a large number of fallen leaves are easy to appear.

3. Improper selection of soil (stagnant water)

Triangle plum is not strict on soil, but it is afraid of stagnant water and is not resistant to waterlogging. therefore, loose and well-drained culture soil must be selected. generally, 4 parts of humus soil, 4 parts of garden soil and 2 parts of sand can be selected. Sun-dried pond mud mixed with some coal cake residue can also be used as basin soil. # p# subtitle # e #

4. Improper fertilization

Due to slow growth or dormancy of plants in hot summer and winter, fertilization should be stopped to avoid fertilizer damage. Do not apply thick fertilizer or raw fertilizer (not fully mature organic fertilizer) to prevent root damage, leaf coke shedding, or even the death of the whole plant.

5. Leaf spot

The disease spot is yellow-brown at first, surrounded by a yellowish-green halo, then expands into a nearly round or irregular spot, the edge is dark brown, and in the later stage, black dots appear on the spot. It is found that a small amount of disease spot can be smeared on it with Dakening cream ointment to cut off the branches with more disease. at the initial stage of the disease, 50% carbendazim wet powder can be used for prevention and treatment, spraying once every 7 to 10 days, and in serious cases, according to practical experience, spray again on the fourth day, and then spray every 7 days. The control effect was good for 3 or 4 times in a row.

6. Brown spot

Brown spot is a damaged leaf, which produces yellow-brown to light brown spots with a diameter of 0.1~0.5cm on the leaf surface.

The prevention and control methods of brown spot: 1, make the plant ventilated and transparent; 2, pay attention to increase or maintain the humidity of leaves; 3, cut off the diseased branches and leaves in time when there is infection, and destroy them; 4. In the initial stage of infection, spraying 1000 times solution or other fungicides can inhibit the development of the course of the disease.

In the culture method of triangular plum, it has been introduced that although triangular plum does not have high requirements for soil, it is afraid of stagnant water and is not resistant to waterlogging, because it is necessary to choose loose and well-drained soil. So once the soil is strong and undrained, the leaves will turn yellow over time.

But for unnecessary trouble, in peacetime maintenance, we should strengthen ventilation, maintain the humidity of the leaves, and avoid the damage of diseases and insect pests.

6. Environmental abrupt change

If the above points can be excluded, then there is another reason for the yellowing of triangular plum leaves, that is, the sudden change of environment. In this case, it is generally found that flower friends who buy triangular plum online may not adapt because of a great change in the growth environment, and the leaves will appear yellow and dry after a period of time.
