Last Updated: 2024/11/06, There are five reasons. The first watering is not suitable, it is necessary to adjust the watering method. The second light is too little, especially in winter for about eight hours. Third, the drainage of the soil is too poor to withstand waterlogging, so it is necessary to change the soil. Fourth, fertilize too much or use raw fertilizer, suspend fertilization. Fifth, suffering from "leaf spot disease", deal with diseased leaves and spray.

1. Adjust the watering method

(1) the specific reason: more water or less water is not good. To sum up, the unscientific watering method can easily lead to the yellowing of leaves.

(2) solution: adjust the watering method. Spring and autumn can be once a day; twice a day in summer, in the morning and evening; watering can be controlled during winter dormancy and slightly moist.

2. Increase the lighting time

(1) specific reason: triangulated plum is a positive plant, if the light is too weak, the leaves are easy to turn yellow and the growth is weak.

(2) solution: it is best to see more sunlight at other times except in a semi-shaded place at the beginning of the transplantation. It lasts at least eight hours in winter, but shade is needed when summer is too strong.

3. Change the soil

(1) specific reason: soil drainage is too poor, stagnant water can not be discharged, it is easy to make the leaves yellow.

(2) solution: switch to soil with good drainage, for example, humus soil, garden soil and sand can be mixed in a ratio of 4: 4: 2.

4. Suspension of fertilization

(1) specific reasons: too much fertilizer or the application of raw fertilizer will produce fertilizer damage and make the leaves yellow.

(2) solution: first suspend fertilization for a period of time. Do not use raw fertilizer, thick fertilizer, and do not apply too much fertilizer at one time.

5. Spraying carbendazim

The main results are as follows: (1) the specific reason: "leaf spot" is easy to affect the plant and make the leaves yellow.

(2) solution: cut off the branches that are frequently affected. Then, spray carbendazim once a week to ten days, a total of three or four times. If very serious, the interval can be adjusted to four days.
