Why do the leaves of jasmine turn yellow easily?

>

The leaves of jasmine are thinner and more sensitive than ordinary flowers, and the leaves are yellow or even scorched in potted plants, which indicates that the normal growth of the plant has been affected and the root system has been partially necrotic. There may be many reasons, but they are as follows:

The main results are as follows: (1) if the plant has been growing normally and the leaves suddenly turn yellow, especially the top tip is scorched, it may be caused by improper fertilization, excessive fertilizer concentration or the application of r-immature fertilizer, resulting in root burning. In this case, if it is not serious, you should water more and dilute the fertilizer. In serious cases, it is necessary to remove part of the persistent soil, replant it, put it in a semi-shaded place, and then gradually return to normal maintenance after sending out new shoots.

(2) if the old leaves are withered and yellow, it is caused by excessive drought and lack of water; if the leaves are wrinkled and the veins are green, it is a sign of too much watering. Too much water leads to the lack of oxygen in the soil, suffocating the roots and causing insufficient water supply. You can replenish water slightly in case of drought, stop water in case of waterlogging, and loosen the soil to facilitate water evaporation, and when it is serious, put the basin soil; knock it out, put it in a cool and ventilated place to disperse moisture, and do not expose it to the sun.

(3) Jasmine is an acid-loving soil plant. Alkaline water is often used to water flowers in areas where soil and water is alkaline, and the leaves of the plants will turn yellow. attention should be paid to soil and water improvement and the application of acidic water and fertilizer.

(4) when the plant is damaged by red spiders or shell insects, the leaves will lose green, yellowing or even wither, which can be sprayed with pepper water or 40% omethoate 1000-1500 times.

(5) after the cultivation environment is polluted by harmful gases such as sulfur dioxide, the leaves will appear scorched yellow, especially when coal is used for indoor heating in winter. In addition, dry air, not turning the basin for many years, and lack of fertilizer will also lead to yellowing of leaves. Specific analysis should be made in cultivation and prescribe the right medicine to the case.

What is the reason why the leaves of jasmine are easy to turn yellow?

Many jasmine culture lovers always encounter the same problem when breeding jasmine, that is, when cultivating jasmine, the leaves are easy to turn yellow, and some people do not know the specific reason, so they will delay the treatment of the disease of jasmine.

Why the leaves of potted jasmine turn yellow

If the potted jasmine is not managed properly, the leaves will often turn yellow, the light ones will grow yellow and the flowering is not ideal, and the serious ones will gradually weaken and die. The causes of leaf yellowing are roughly the following.

1. Overwatering. Jasmine likes the soil to be wet, but it is waterlogged. If the potted soil is too wet for a long time, it will cause rotting roots, yellowing leaves and even plant death due to hypoxia. In case of this situation, as long as the basin is moved to a shady place, watering is strictly controlled (if the basin soil is not too dry, it must not be watered again), and the basin soil is often loosened to improve the ventilation of the basin soil, so that the plant can gradually grow new roots after a period of time and the leaves turn green.

2. The soil is alkaline. Jasmine likes slightly acidic soil, such as using water with more salt or tap water for a long time, it is easy to make its plants grow poorly and its branches and leaves turn yellow. If it is caused by the water used for irrigation and the partial alkali of the basin soil, the dilute ferrous sulfate solution can be applied during the growth period, so that the withered old leaves of the plant can soon change from yellow to green.

3. The nutrient supply is insufficient. There is no change of pot soil and fertilization for a long time, resulting in a shortage of nutrients and yellowing of jasmine leaves. In case of such a situation, as long as you change the plant into a pot, replace it with fertile, loose sandy loam, and apply liquid fertilizer regularly (note when applying fertilizer: if it is too thick, or applying the last mature organic fertilizer, it will cause "root burning" and withering and yellowing of branches and leaves). Soon the jasmine will grow normally.

Sometimes the cause of jasmine leaf yellowing is single, sometimes it is caused by a combination of two or more reasons. It is necessary to analyze carefully, diagnose carefully and prescribe the right medicine to the case. Generally speaking, if the plant grows poorly during the growing period, the leaves gradually turn yellow, which is mostly caused by watering water and alkali in the basin soil; if the plants with normal growth suddenly turn yellow, this is often caused by excessive watering or excessive fertilization, resulting in root rot. After finding out the cause, the above measures can be taken to save it.
