What is the reason why the color of jasmine leaves is not green and yellow

1. Soil causes: Soil is also an important factor that causes the yellowing of leaves, jasmine.

If the soil is weakly alkaline, it will cause the leaves to turn from yellow to green, or even fall off, and acidic nutrient soil should be used.

Carry out maintenance. 2. Light and temperature reasons: jasmine is a flower that likes light and warm environment, so it is necessary to place jasmine in a place with sufficient sunlight scattering for maintenance, high temperature in summer, not directly exposed to the sun, pay attention to indoor sharing and cooling, potting soil can not be too dry or wet, otherwise it is easy to cause the pot leaves to turn yellow and wilt.

3. Yellow leaves in winter: improper maintenance in winter will also lead to yellowing of jasmine leaves, jasmine should be placed indoors for maintenance in winter, pay attention to the minimum indoor temperature should not be lower than 3, it is best to keep it at about 10-15, and the leaves will rarely yellow and wilt.

The reason for the yellowing of jasmine leaves lies here, and this method is the best way to prevent it.

The potting soil is alkaline and adjusted with ferrous sulfate.

1) Overwatering. Jasmine likes moist soil, but is afraid of stagnant water, if the potting soil is in a wet state for a long time, it will cause root rot due to lack of oxygen, and the leaves will turn yellow and even die.

2) Soil alkaline. Jasmine prefers slightly acidic soil, such as water or soil culture jasmine with more saline and alkali components, which is easy to make its leaves yellow.

3) Insufficient nutrients. The lack of soil change for a long time causes the leaves to turn yellow due to insufficient nutrients.

4) Improper fertilization. Excessive fertilization or unrotted organic fertilizer will cause "root burning" and cause yellowing. (5) Pests. Pests such as red spiders and scale insects can also cause yellowing of leaves.

6) Insufficient light. Jasmine needs plenty of light to grow well.

Jasmine sometimes leaves turn yellow suddenly, which is caused by overwatering and rotting roots. The way to improve it is to water in strict moderation. Watering must pay attention to the climate, plant size, branch and leaf growth and pot size and other conditions, the potting soil is not too dry, do not water, both to keep the potting soil moist, but also not to accumulate water.

The second is fertilization, which is appropriate under the condition that the potting soil is moist and loose. After the plant is overwintered, apply 1 time of thick fertilizer to promote its rapid sprouts. When the flower buds of new shoots appear, apply 1 thin fertilizer to promote their flowering to be large and fragrant;

Wait for the first stage of flowers to bloom and then apply a thin fertilizer to encourage them to grow the second batch of flowers early. The fertilizer applied must be fully decomposed, otherwise, after application, it will rot and insects, or the heat generated by fermentation will "burn to death" the flowers and trees. Thirdly, it is to prevent and control pests and diseases in a timely manner.

There could be the following reasons:

1. Alkaline pot soil: 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, ferrous sulfate solution or alum fertilizer water can be added to increase the soluble iron in the soil can be solved.

2. Malnutrition: When cultivating in pots, soil change and fertilization are not carried out for a long time, resulting in insufficient nutrients in the soil and yellowing of leaves.

3. Temperature discomfort: Moxiao Minglunli is not cold-resistant, in case of low temperature, the normal metabolism of the body will be disordered, resulting in yellowing of the leaves, you can adjust the microclimate of the ring environment, add plastic film or move it into a place with high temperature for maintenance and management.

4. Lack of light: the growth of jasmine.

Yellow leaves due to improper watering: the amount of water should be controlled to keep the potting soil moist and not waterlogged. Yellow leaves due to improper fertilization:

The pot should be changed in time, and then the habit of applying thin fertilizer should be maintained. Light temperature reason: Place jasmine flowers in a place with sufficient sunlight scattering for maintenance.

Winter: Keep it around 10-15.

1. Improper watering.

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. Improper fertilization.

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 the leaves yellowing, in the above situation, should be timely to change the pot of jasmine, usually thin fertilizer, choose fertile leaves water-soluble fertilizer, to ensure the normal nutrients of the plant**.

3. Soil causes.

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, or even fall off, should be maintained with acidic nutrient soil.

Fourth, light and temperature reasons.

Jasmine is a flower that likes light and warm environment, so it is necessary to place jasmine in a place with sufficient sunlight scattering for maintenance, high temperature and hot in summer, not directly exposed to the sun, pay attention to indoor equal division and cooling, potting soil can not be too dry or moist, otherwise it is easy to cause the pot leaves to turn yellow and wilt.

5. Yellow leaves in winter.

Improper maintenance in winter will also lead to yellow jasmine leaves, jasmine should be placed indoors for maintenance in winter, pay attention to the minimum indoor temperature should not be lower than 3, it is best to keep it at about 10-15, the leaves will rarely yellow and wilt.

Overwatering, alkaline soil, lack of iron, insufficient nutrients.

The causes of yellowing of leaves are roughly as follows:

1.Overwatering. Although jasmine likes moist soil, it is waterlogged. If the potting soil is too wet for a long time, it will cause root rot, yellowing of leaves, and even plant death due to lack of oxygen.

2.The soil is alkaline. Jasmine likes slightly acidic soil, such as using water with more salt content or long-term use of tap water, which is easy to make its plants grow poorly and the branches and leaves yellow.

3.Insufficient nutrients**. Long-term failure to change the potting soil and fertilize has caused the supply of nutrients to exceed demand, resulting in the yellowing of jasmine leaves.

4.Fertilizer deficiency: If the whole plant yellows or develops upwards from the lower older leaves, nitrogen deficiency can be diagnosed. At this time, the pot should be changed or nitrogen fertilizer should be added, and at the same time, fertilizer containing more phosphorus and potassium should be applied, which can make the leaves turn yellow and green, and bloom luxuriantly.

5.Jasmine prefers fertile, acidic soil, and if the soil is alkaline, it will affect the absorption of iron, so that the new leaves will appear yellowing first. Therefore, during the growth period of jasmine branches and leaves, and now buds bloom, alum fertilizer should be applied once a day or so.

1.Improper lighting

When jasmine is exposed to sunlight for a long time, the light received is insufficient, which will cause the plant to grow and the leaves to yellow, and when the jasmine is exposed to sunlight for a long time, the strong light will burn the plant, causing the plant to turn yellow and the leaves yellow.

Solution: Place jasmine indoors or other places with sufficient scattered light to cultivate, and regularly release it outdoors to receive light in spring, autumn and winter when the indoor light is dim.

2.Improper watering

When watering jasmine, when watering too little or not watering for a long time, the plant is easy to turn yellow because of dehydration, and when watering too much, it causes water accumulation in the potting soil, and the roots are easy to rot when soaked in water for a long time, and when the roots rot, the absorption of water and nutrients is weak, and the leaves cannot obtain enough water and nutrients, so they turn yellow.

Solution: Watering jasmine should follow the principle of "seeing dry and wet", watering when the surface of the soil begins to dry, watering until the water seeps out from the bottom of the soil can be stopped, watering too little to cause the leaves to yellow, should be watered in time to permeate once, watering too much to make the roots rot and cause the leaves to yellow, should dig out the roots for treatment, and then change the soil and replant.

3.Improper fertilization

In the flowering and growth periods, when these plants need fertilizer, too little or no fertilization, the plants are easy to turn yellow because of insufficient nutrients, but when too much fertilizer is applied and the fertilizer is applied directly above the roots, it is easy to cause plant fertilizer and damage the root tissue structure, and the leaves are also yellow.

Solution: Fertilization should be applied in small quantities many times, thin fertilizer frequently, not without fertilization, nor too much fertilizer at one time, and fertilization should be applied in the soil near the roots, when the jasmine leaves are yellow because of too little fertilizer, timely fertilizer, because of too much fertilizer and the leaves are yellow, replace the soil with too much fertilizer, prune the branches and roots, and replant.

4.Soil alkalization

Jasmine grows well in slightly acidic soil, but when the soil is used for too long, it will gradually become alkaline, especially in northern places where the soil and water are more alkaline, and the degree of soil alkalinization is higher, while jasmine grows poorly in alkaline soil, and the plants will turn yellow and the leaves will turn yellow.

Solution: In order to prevent soil compaction and alkalinization from being unfavorable to the growth of jasmine and causing jasmine leaves to turn yellow, you can replace the soil every 2 years, and add ferrous sulfate to the water every once in a while to increase soil acidity when watering.

.Hypothermia frostbite

Jasmine is not resistant to frost, and when the temperature is too low in winter, if the jasmine is placed outdoors, it is easy to frostbite the plant, and the leaves will also turn yellow after frostbite.

Solution: When the temperature is too low in winter, move the jasmine into a warm place indoors for maintenance, it is best to control the room temperature at 10 to 15, and when the jasmine appears frostbite, it is necessary to strengthen the maintenance management.
