Jasmine leaves are yellow and wilted and rotten roots, and jasmine leaves are yellow and withered, w

The cause of yellowing, wilting, and rotten roots of jasmine leaves.

The amount of watering. Watering too much or too little can cause jasmine leaves to turn yellow. When watering too much, the soil is waterlogged, the root system is not breathing, and it is easy to rot the roots, which is manifested as 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.

Amount of fertilizer. 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; Too little fertilization will make the roots of the plant a lump, can not get the absorption of nutrients, resulting in the leaves turn yellow, in the above situation, should be timely to repot the jasmine, usually apply the fertile leaf water-soluble fertilizer, thin fertilizer, to ensure the normal nutrients of the plant**.

Light and temperature.

Jasmine is a flower that likes light and warm environment, so it is necessary to place jasmine in a place with sufficient sunlight for maintenance, high temperature and heat in summer, not directly exposed to the sun, pay attention to indoor cooling, potting soil can not be too dry or wet, otherwise it is easy to cause yellowing and wilting of potted leaves.

Improper winter maintenance can also cause jasmine leaves to turn yellow, jasmine should be kept indoors in winter, and the room temperature should be around 10 degrees Celsius to safely overwinter. If the local climate is relatively cold, flower friends who have no heating can put a thermal insulation bag on the plant to properly ventilate the jasmine to ensure safe wintering, and the falling of leaves will be alleviated.

Analysis and treatment methods for the causes of yellowing and drying of jasmine leaves:

1. Alkaline potting soil causes jasmine leaves to turn yellow: long-term irrigation with alkaline water will cause iron deficiency due to aggravated alkalinity, resulting in poor plant growth and yellowing of branches and leaves.

Solution: Ferrous sulfate solution or alum fertilizer water can be added to increase the soluble iron in the soil.

2. Yellowing of jasmine leaves due to stagnant water: If the potting soil is in a humid state for a long time, it will cause suffocation and rot of the root system due to lack of oxygen, and the plant will not be able to absorb nutrients and make the leaves yellow, or even wither and die.

Solution: Watering should be carried out between dry and wet, and do not let the potting soil always be wet.

3. Insufficient light causes jasmine leaves to turn yellow (lack of light yellow): Jasmine needs sufficient light conditions during its growth period, and it can be maintained in a good state for a period of time in semi-shade, but in the shade, yellow leaves, withered tips, and even fallen leaves will soon appear.

Solution: To meet the light needs of jasmine, occasionally take the balcony to a sunny place to dry.

Fourth, the temperature discomfort causes the jasmine leaves to turn yellow: jasmine is not cold-tolerant, in case of low temperature, the normal physiological metabolism in the body will be disordered, resulting in the yellowing of the leaves.

Solution: The environmental microclimate can be adjusted, plastic film can be added or moved to a place with high temperature for maintenance and management.

5. Excessive fertilization of jasmine leads to yellowing of leaves (fat yellow): Excessive fertilization will cause root burning, and it will also cause yellowing of leaves.

Solution: In this case, the potting soil should be replaced immediately, and the principle of thin fertilizer should be applied frequently. Usually apply Bika foliar fertilizer.

6. Root rot causes jasmine leaves to turn yellow: If the flower soil is not well drained, it will keep the potting soil in a damp state for a long time, which will cause root rot. Jasmine will cause the leaves to turn yellow due to lack of oxygen, and even wither and die.

Solution: In this case, first of all, we must ensure the principle of watering when dry and wet, watering when there is a shortage of water, watering should be done thoroughly. Then it should be noted that it is best to choose breathable vegetable soil to ensure that the ventilation can contain nutrients.

7. Pests and diseases cause jasmine leaves to turn yellow: Jasmine common insect pests are red spiders, and if the pests are not removed for a long time, the leaves will turn yellow.

Solution: This point should be sprayed with special insecticides in time, and the plants should also pay attention to ventilation.

Many flower friends find that jasmine leaves are yellow, weak growth, and do not bloom in the spring, at this time many people will throw away directly, this idea is wrong, what we need is not to change the flowers but to change the pot, as long as the operation is done properly, it will take up to a month to recover.

Jasmine because of its vigorous growth and flowering, so the need for fertilizer and water is particularly large, it will grow the root system all over the pot, even if it is planted with nutrient soil, the lack of nutrients in the pot is also very serious, and the soil becomes slightly alkaline, resulting in its yellow leaves, falling leaves, slow growth, and even no flowering, so what to do now is to repot it. Generally, as long as the pot of jasmine is not very large, it is most suitable to raise it for a year and change the pot every spring.

And there are many flower friends who believe that the plants in the flowering period can not be fertilized, and will stop fertilizing when the jasmine blooms, and even more, the jasmine is basically not fertilized in a summer, so that the jasmine is prone to serious fertilizer deficiency, and the leaves appear to be yellow and green in a large area.

Therefore, when raising jasmine, we must insist on top dressing, even if jasmine is in the flowering period, we must insist on balanced growth fertilizer at least once a week, at this time, it reflects the advantages of non-dilution direct injection nutrient solution, you can take the nutrient solution to spray jasmine once a week, I am now using Zhulu Qingpai Green Leaf King, simple and easy to use.

Change the soil directly, add organic fertilizer and nutrient soil for watering, and then spray foliar fertilizer.

1. Depotting and pruning: Immediately depot jasmine and cut off rotten roots and dry branches and leaves.

2. Replanting: Plant jasmine in soft, breathable soil with plenty of organic matter.

3. Control watering: water every 7-10 days to avoid root rot.

4. Top dressing management: top dressing 1-2 times of nitrogen, phosphorus and potassium compound fertilizer in the growth period.

The reasons for the yellowing and drying of jasmine leaves are: alkaline potting soil, insufficient fertilization, and unsuitable temperature.

1. The potting soil is alkaline

If you use alkaline water to water the soil for a long time, it will cause the soil to be alkaline, or directly use alkaline soil to maintain the plant, which will affect the absorption of the elements by the root system, resulting in poor growth of jasmine and yellowing of leaves.

2. Insufficient fertilization

In the process of maintaining jasmine, there is no timely fertilization and replacement of potting soil, resulting in insufficient nutrients in the soil, which can not meet the nutrient needs of the plant growth clump sleepy development, resulting in poor leaf growth, yellowing and wilting.

3. The temperature is uncomfortable

Jasmine has low cold tolerance, if the plant is placed in a cool and cold place to maintain, it will cause the normal physiological activities of jasmine to be disturbed, resulting in symptoms such as yellowing and falling of leaves, so in the maintenance process, when the temperature drops, it is necessary to take cold protection and warmth measures.

Jasmine repotting time and method

1. Repotting time

When jasmine breeding, every 1-2 years to change the pot 1 time, to avoid soil compaction, affect the healthy growth of the plant, repotting is generally carried out in the spring, at this time the temperature is stable, warm, conducive to slow down the seedlings, so that jasmine as soon as possible to resume growth.

2. Depotting treatment

Jasmine should stop watering a few days before changing pots to facilitate depotting, and then pat the pot around with your hands to make the soil fall off, and then use a small shovel to rotate along the inner wall of the pot 1 circle to take out the plants, and cut off rotten roots, old roots, and dead roots.

3. Plant in pots

First, the bottom of the pot is padded with tiles to increase aeration, and then the prepared substrate is loaded into it, and then the jasmine is righted and planted into the soil, and slowly filled and compacted to make the roots and soil fully contacted, and speed up the recovery of the plant.

Jasmine leaves turn yellow and dry up and the leaves can be used to improve the soil, measure sunlight, watering, fertilizing, pruning.

1. Soil jasmine has relatively high requirements for soil.

After all, it is also a beauty flower, and we can't raise it roughly, we need to prepare soil with good water permeability and aeration for jasmine, and we can't just use the soil in the park.

2. The growth of sunshine jasmine needs sufficient sunlight.

Jasmine is a flower that likes sunlight very much, and it is a strong positive plant, and it is commonly said that jasmine cannot be sunburned.

3. Watering. Summer is already hot, water evaporates quickly, and jasmine flowers need a lot of water during the rapid growth period, so watering is particularly important.

4. Fertilization. Jasmine is very fond of fertilizers, especially during its growth cycle, which is the period when jasmine grows and blooms rapidly, and it is best to apply liquid fertilizer once a week.

5. Pruning. There are many flower lovers who are reluctant to prune jasmine, and it is understandable that well-cared for flowers are reluctant to prune, but if we are reluctant to cut some branches, we will waste a lot of nutrients.

Jasmine leaves turn yellow and dry up leaves, and the solutions are: replenish water, clean fertilizer, and increase temperature.

1. Replenish water

The yellowing and withering of jasmine leaves may be the cause of lack of water, at this time, it is necessary to water it once, and loosen the soil to allow the water to penetrate, and move the jasmine to a place with weak light to slow down the rate of water evaporation and restore its growth.

2. Clean up the fertilizer

After the jasmine leaves wither and fall off, check the root system in time, clean up the excess fertilizer, if you apply liquid fertilizer, you can water the jasmine more, dilute the fertilizer in the soil, and then move the jasmine to a ventilated place for maintenance.

3. Increase the temperature

Jasmine has poor cold tolerance, and if it grows at a low temperature for a long time, the leaves will suffer severe frostbite, so that Li Juhe will have yellow leaves dry up and lose leaves, at this time, the jasmine should be moved to a warm place, and the temperature should be controlled at about 15 degrees Celsius.

Flowering management

1. Pruning: Jasmine is the most vigorous in 3-6 years of seedlings, and it will age year by year, so it must be re-cut and updated in time. Before germination in the Spring Festival, the raw branches can be properly cut short, and the base is retained 10-15 cm, so that most of the stout new branches occur, if the new branches grow very vigorously, they should be topped when they grow up to 10 cm, and the secondary shoots are promoted, then the flowers are more, and the flower type is compact, and the ornamental value is high.

2. Note: Pruning should be carried out on sunny days, which can be combined with leaf thinning to remove diseased branches, and the plants can be adjusted to facilitate growth and pregnant buds flowering.
