How to solve the problem that the leaves of tangerines turn yellow and fall off as soon as they turn yellow?

In our usual topic, when we talk about tangerines, we don't have to think about potted plants. in our concept, it is an ornamental plant. Its magic is that it can bear fruit many times a year, and its fruit period is long, and its fruit is round and shiny. It greatly increases its ornamental value. So what should we do if we grow our own plants in the case of falling leaves? let's take a look.

What if the leaves of the tangerines fall?

The main results are as follows: 1. The phenomenon of falling yellow leaves is caused by watering too wet. usually, watering is not easy to get too wet, and the over-wet soil is easy to cause root rot and yellow leaves fall. It is best to keep the soil dry after watering, so that it is beneficial to the growth of the root system so that it is not easy to lose leaves, so that the root system is not easy to grow.

2. The soil plate is hard and impervious, so the irrigated water can not penetrate into the soil layer, resulting in most of the roots can not absorb water and nutrients, resulting in the loss of water and nutrition of leaves and the symptoms of yellow leaves. The best way is to loosen the soil properly, which is conducive to soil loosening, ventilation and drainage, which is conducive to root growth.

3. Planting potted plants indoors due to lack of light and yellow leaves, it is best to put them indoors in a sunny ventilation place to reduce its photosynthesis and reduce the phenomenon of overgrown yellow leaves, and it is best to move out of the sun for 2 hours in the morning and evening to enhance photosynthesis and strengthen the outdoor sunshine.

4. There are pests and diseases, which can easily cause leaves to fall. It can be observed that if the leaves are caused by pests, insecticides can be used to kill insects, and if they are caused by bacteria, antibiotics can be used to treat diseases.

5. Lack of nutrients or excessive fertilization is also easy to cause symptoms of yellow leaves, digging holes to the side according to the amount of compound fertilizer and mineral additives, the amount is not easy to prevent excessive.

The solution to the yellowing of tangerine leaves

If it is dry, make sure to water it once a week. For the reason of not seeing the sun, it is recommended to put it under the south window to see the sun, or turn on the lights for a long time at night. After the leaves turn yellow, the leaves will fall soon. I have encountered this situation, so take measures as soon as possible. The oranges above can not be picked now and must be picked before the end of the first month after the Spring Festival, otherwise it will affect the first flowering and fruit.

Matters needing attention of potted tangerine in family

1. The turning time of potted four Seasons Orange should be in the first three months of the Gregorian calendar, that is, before and after the lunar calendar. Before turning the pot, pick the orange fruit, trim the orange tree into a ball, keep each side branch 5 to 7 cm long, and cut off the overdense or thin branches. In addition, cut off about 1/3 of the small roots, do not hurt the main roots, remove the old mud, and keep the bowl roots.

2. Put the base fertilizer in the basin, put the pruned plants back in the basin, then spread the fertile new pond mud and put it in a ventilated place. Before the plant sprouts, do not bask in the sun for a long time, do not drench too much water, as long as keep moist, do not fertilize too much. Orange trees sprout new buds, when the leaves increase, you can pour more water, fertilize twice a month, apply light nitrogen fertilizer, or soak human urine and peanut wheat. If pests are found, they should be prevented in time.

In mid-July, oranges blossom gradually, and flowers should be properly preserved. If it does not blossom by mid-August, remedial measures should be taken. Put the oranges in a sunny place to bask in the sun (light can be added at night), water less (wait for the leaves to wrinkle before watering), until there are some white spots in the axils of the leaves, this is the flower, and then return to normal management.

This kind of plant is very common during the Spring Festival, and the golden fruit is very beautiful. through the above, we all know that although it is very beautiful, it will not look good if it is not well taken care of, especially in terms of pests and diseases. I don't know if you have learned about some diseases and insect pests and their control measures in the four seasons.
