Jasmine leaves dry yellow do not drop leaves, jasmine leaves yellow dry dry and what to do if the le

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

1. Yellowing of jasmine leaves due to alkaline potting soil: 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 caused by stagnant water: If the potting soil is in a humid state for a long time, it will cause root suffocation and rot 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, 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.

4. Temperature discomfort leads to yellowing of jasmine leaves: jasmine is not cold-tolerant, and in case of low temperature, the normal physiological metabolism in the body will be disordered, resulting in yellowing of 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 causes yellowing of leaves (fat yellow): Excessive fertilization will cause root burning and yellowing of leaves.

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

6. Root rot causes jasmine leaves to turn yellow: If the flower soil is not well drained, it will make 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.

Jasmine Care Tips:

1. After each flower, the residual flowers should be removed in time and the long branches should be properly repaired. Fertilizer should also be applied once; If you pursue the quality of flowers, the first flower of each year should be removed, and the second flower can be ensured.

2. When buying jasmine, you should try to buy young plants, jasmine blooms on new branches. Old trees that have formed stumps should be bought with caution, because old stumps often bloom less, and they are often plants eliminated by flower farmers after the peak of flowering;

3. After leaving the house in spring, the soil should be changed in time, the old leaves of the next year should be removed, and the long branches should be repaired (about 10 cm or so) 4. Insect pests are caused by weak plants and poor ventilation, and strong plants rarely occur.

4. Fertilization should be stopped in early September to facilitate the lignification of branches and facilitate wintering.

Boost the light! Spray foliar fertilizer!

The jasmine leaves are yellow, dried up, and the leaves are treated as follows:

1. Depotting and pruning.

Jasmine leaves dry and fall, may be caused by the rot of the root system of the plant, to immediately remove the jasmine from the original pot, and then use sterilized sharp scissors to cut off the blackened rotten roots and dry yellow leaves of the plant, and then spray potassium permanganate solution to the fracture of the jasmine to disinfect and sterilize.

2. Replant.

When replanting jasmine, it is necessary to use a mixture of humus, coconut peat and peat soil to make a growing medium, and then apply plant ash and cake fertilizer to the soil, and then plant the jasmine into the soil and move it to a ventilated semi-shaded environment for slow seedling.

3. Control watering.

Jasmine is not tolerant to waterlogging, when cultivating jasmine, if watering too often, it will lead to water rotten roots, you need to control the frequency of watering, it is best to water every 7-10 days, and when watering jasmine, the tap water should be left for 1-2 days before use.

4. Top dressing management.

Jasmine needs sufficient nutrients in the growth process, when cultivating jasmine, it is necessary to apply fertilizer 1-2 times during the plant growth period, you can choose nitrogen, phosphorus and potassium compound fertilizer or well-rotted organic fertilizer, and after jasmine flowering, it should be sprayed with potassium dihydrogen phosphate.

5. 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, resulting in the situation of yellow leaves drying up and losing leaves, so it is necessary to move the jasmine to a warm place and control the temperature at about 15 degrees Celsius.

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 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.

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.
