What causes jasmine leaves to turn yellow? Is the mesophyll yellowish or the veins green?

Summer is the flowering period of jasmine, and if the plant is well maintained, it can bloom more and reflower quickly. If the jasmine at home is yellow and thin, the flowering ability will be greatly reduced. There are two main reasons for the lack of jasmine flowering, one is that the soil is alkalized, the leaves are yellow, and the overall growth deteriorates.

The other is that the fertilization is insufficient, and the flowering ability is reduced. Raise jasmine in summer, often use 2 kinds of fertilizer water, bloom more, and the leaves are green and not yellow.

Fertilize before flowering

If you want jasmine to bloom more, have a long flowering period and a strong fragrance, you can't do without phosphorus and potassium fertilizers. In summer, jasmine is often applied with some phosphorus and potassium fertilizer, which is good for promoting flowering and reflowering. If your jasmine is leafy, apply potassium dihydrogen phosphate every 7 to 10 days, 3 times in a row, and it will almost be ready to bloom.

If your jasmine branches and foliage are not too lush, apply Huaduoduo No. 2, or potassium dihydrogen phosphate and compound fertilizer (inorganic compound fertilizer and organic fertilizer are fine) to make them bloom.

Fertilize after flowering

After the jasmine blooms, prune it in time, and it will soon be able to rebloom. After pruning, compound fertilizer should be applied in time to promote the germination and growth of new branches. When the new branches have germinated and the leaves are comfortable, you can apply phosphorus and potassium fertilizer to reflower as soon as possible.

If you keep applying phosphorus and potassium fertilizer to jasmine, the nitrogen element is missing, the germination ability of new branches is poor, and the flowering ability will be reduced. Therefore, when growing new branches, compound fertilizers should be used, and phosphorus and potassium fertilizers should be used when flowering.

Jasmine is a southern flower that prefers an acidic growing environment and has a greater need for iron. In summer, the amount of water evaporation is large, and watering is more frequent. If the local water quality is alkaline, jasmine is prone to soil alkalinization, yellowing of new leaves, and poor growth.

Specifically, the mesophyll of the new leaf is yellow and whitish, the veins are green, and the whole leaf looks like a spider's web.

When the new leaves of jasmine are yellowed due to soil alkalinization, photosynthesis is weakened, and the synthesis of organic matter decreases, and the growth will become worse and worse, and the new branches will be thin and weak, making it difficult to flower. If left unchecked, the situation will become more and more serious, the resistance of the whole plant will decrease, and the branches may slowly dry up, and life will come to an end completely. The yellowing of new leaves of jasmine is most likely to occur in the summer high temperature season, so it must be paid attention to.

The best way to prevent the yellowing of new jasmine leaves is to use acidic fertilizers regularly, especially well-rotted organic fertilizers, which can improve soil fruit and keep the soil slightly acidic or acidic. If you use alkaline or neutral fertilizer for a long time and water jasmine with alkaline water, the phenomenon of yellow and poor growth of new leaves is particularly likely to occur.

When the new leaves of jasmine turn yellow, if the situation is not serious, watering some organic fertilizer can be improved. If the situation is severe, the new leaves are yellowing obviously, and the growth of the plant has been affected, it is best to water ferrous sulfate solution to change the acidity and alkalinity of the soil and supplement iron ions. Ferrous sulfate is used once every 10 days for 7 days, adjusted into a 1000 times solution, and the roots are irrigated when the potting soil is dry.

Ferrous sulfate solution can also be used as a daily fertilizer to prevent the yellowing of new jasmine leaves, watering or foliar spraying every 15 days or so, so that the leaves become green and shiny without yellowing.

It is very likely that the plant is deficient in nutrients, so nitrogen and potassium fertilizers should be supplemented in time to promote the growth of plant rhizomes, moderate watering, keep the soil moist and place it in a ventilated place. It can also be caused by a lack of light.

The leaves of jasmine are yellow and dry, and they must not be sunburned, because jasmine is not afraid of the sun at all, and they especially like the sun, and the main reasons for the yellowing and drying of jasmine leaves are probably the following points, although overwatering jasmine likes moist soil, but is afraid of waterlogging, if the potting soil is too wet for a long time, it will rot the roots, resulting in yellowing of the leaves, and may even cause deathStop watering, move the pot to a cool and ventilated place, loosen the soil, After a while, the leaves will slowly turn green.

The leaves of jasmine are yellow, not all yellow, but the mesophyll is yellow, and the veins are green, which is caused by a typical iron deficiency, and iron needs to be supplemented.

Potting soil is alkaline: long-term irrigation with alkaline water, due to the aggravation of alkalinity and iron deficiency, resulting in poor plant growth, yellowing of branches and leaves, can be added with ferrous sulfate solution or alum fertilizer water, increase the soluble iron in the soil can be solved.

The leaves of the flowers are yellow, don't worry about it, distinguish the reason and do it well!

<>1. Watering too much or too little can cause jasmine leaves to turn yellow. When watering too much, the young leaves are dull, the old leaves do not change much, and the new branches gradually shrink and stop growing; Watering too little, will make the old leaves gradually fall from top to bottom, but the normal growth of new leaves, nutrients ** insufficient, encounter the above phenomenon, should pay attention to the appropriate amount of watering, to ensure that the potting soil is moist, not waterlogged.

2. The fertilization of jasmine is also very important, too much fertilization causes the color of new leaves to turn brown, and the old leaves gradually turn yellow and wither; Fertilization too little will make the roots of the plant a lump, can not get the absorption of nutrients, resulting in yellowing of the leaves, in the above situation, should be timely to repot the jasmine, usually thin fertilizer, to ensure the normal nutrients of the plant**.

3. Soil is also an important factor that causes the leaves to turn yellow, the soil of jasmine should be acidic soil, if the soil is weakly alkaline, it will cause the leaves to turn from yellow to green, and even fall off, and acidic nutrient soil should be used for maintenance.

Yellowing is generally divided into the following types, water yellow, dry yellow, lack of fertilizer, and fertilizer. Depending on the situation, different measures may be taken. If you water too much, control the water appropriately and change your watering habits.

Lack of water in time, lack of fertilizer on fertilizer, lack of what to make up, fertilizer damage is not serious, you can water more to dilute the fertilizer in the soil, serious situations need to change pots in time.

Jasmine leaves are yellow, first of all, we must find the specific reason, there are many cases that cause the leaves to turn yellow, and different reasons will have different manifestations. Yellowing is generally divided into the following typesWater yellow, drought yellow, lack of fertilizer, fertilizer damage

1. Yellowing of leaves after too much watering

This is a very common phenomenon, some novice flower friends, do not pay attention when watering, always worry about the lack of water in the flowers, so they have been watering.

Too much watering will cause the root system to be stuffy in water for a long time, and the root system will be blocked from breathing, which will affect the growth of above-ground partsAs a result, the leaves turn yellow

Yellowing from excessive watering generally starts from the lower leaves, and in severe cases, the leaves will fall off

2. Insufficient watering

Not watering for a long time is also bad for jasmine。Lack of water to appear leaf yellowing, often accompanied by leaf wilting, after the lack of water the leaves do not absorb enough water, it will be soft and drooping, and even the tip of the leaf is dry.

3. Lack of fat and yellowing

Jasmine needs enough fertilizer to grow**, and if it is not fertilized for a long time or the fertilization is uneven, the leaves will also turn yellow.

Lack of different fertilizers, yellowing is not the same, there are two main types, nitrogen deficiency and iron deficiency.

Nitrogen fertilizer is very important for the growth of plants, the growth of branches and leaves, the synthesis of chloroplasts all need nitrogen, if nitrogen fertilizer is insufficient, the leaves of jasmine appear to be pale yellow as a whole, and the growth is worse than that of the Imperial Hall.

Jasmine iron deficiency is first manifested in the young leaf part, the leaf appears green between the leaf veins, the leaf veins are what we usually call the tendons, the leaf tendons are green, and the tendons are yellow.

4. Yellowing of fertilizer

Fertilizer damage is also a relatively common problem, after the occurrence of fertilizer damage, the root system is damaged, affecting the growth of leaves.

It is easy to judge the more serious fertilizer damage, and the leaves of jasmine dry up from the tip of the leaf. However, in the case of a small amount of fertilizer and overwatering, it is similar to the yellowing of the leaves.

This judgment can only be determined according to the usual maintenance, too much watering or too much fertilization, I think I am very clear.

5. Insufficient light

Jasmine is a masculine flower, there are still certain requirements for pure acacia in the light, potted jasmine in addition to the summer need shade, other seasons to bask in the sun.

If the maintenance environment is relatively poor, it will affect the photosynthesis of jasmine, resulting in yellowing of leaves.

The above are several reasons for the yellowing of jasmine leaves, and different measures can be taken in different situations. If you water too much, properly control the hidden water of the pants and change the watering habits.

Lack of water in time, lack of fertilizer on fertilizer, lack of what to make up, fertilizer damage is not serious, you can water more to dilute the fertilizer in the soil, serious situations need to change pots in time.

There may also be a lack of water and light, or a lack of nutrients or some pests and diseases, you can add some other material conditions to see if it can be improved, if it can't be improved, you need to buy medicine.

It is likely to be caused by a lack of nutrients or too much watering, you can supplement some fertilizer, or you can manage it according to scientific methods, do not water too much.

It is very likely that there is a lack of fertilizer, it may be too much watering, or it may be caused by some bacteria, in this case, we must top dressing in time, eat more organic fertilizer and water less, promote ventilation, and spray some pesticides to prevent and control pests and diseases.

It could be a lack of some nutrients, too much watering, or some pests and diseases. You can apply some fertilizer to the soil, and pay attention to drainage, always observe the growth, and use some drugs to prevent and control pests and diseases.

Jasmine is infected with insect pests such as red spiders, which attach to the leaves and branches of jasmine, sucking the water of the leaves and branches, causing the leaves to dry up and fall off, and even the entire plant stalk will be sucked clean by it nutrients and water, and it will dry up.

Regularly check the back of the leaves, find that there are insect infestations, timely spraying, timely **, find that it is late, jasmine will be damaged by insect pests, resulting in can't be saved.

If the indoor ventilation is not good, it is also very good to spray it regularly once a month to prevent the occurrence of insect infestations.
