What to do with raising flowers and yellow leaves, and raising flowers and leaves yellowing remedies

1. Increase air humidity.

1. Reason: It is a tropical plant, the air humidity is relatively high, if the air humidity is not up to standard, there will be dry leaves.

2. Solution: Spray its branches and leaves with water mist in the morning, noon and evening to keep the branches and leaves moist.

2. Reduce light intensity.

1. Reason: Loose-tailed sunflower likes the sun, but if the sunlight is too strong, the leaves will also dry up.

2. Solution: Sunflower is a sun-loving plant, and it is necessary to ensure more than eight hours of sunlight every day, and when the sun is strong at noon, it should be properly shaded. This not only meets the light needs, but also does not allow it to be burned by the sun.

3. Proper watering.

1. Reason: Loose tail sunflower has a large demand for water, so insufficient watering will cause the leaves to dry out.

2. Solution: Water two to three times a week, water thoroughly each time, and increase the number of watering times appropriately. Spray it with water every morning, noon and evening to keep the branches and leaves moist.

Fourth, apply light fertilizer.

1. Reason: Loose tail sunflower likes fertilizer but does not like thick fertilizer, so fertilizer should avoid thick fertilizer.

2. Solution: During its growth period, apply Bika water-soluble fertilizer once a week; During the dormant period, fertilizing two to three times a month is fine. If the fertilizer is applied with chemical fertilizer, it should be about ten centimeters away from the roots when applied, and it should not be applied to the roots to avoid burning the roots.

1. Appropriate light: If the light is too strong and sunburned, shade it as soon as possible. If it is caused by a lack of light, move to a place where there is light and get more sun.

2. Appropriate amount of watering: If it is a drought caused by lack of water, replenish water and moisturize as soon as possible. 3. Reasonable top dressing

If it is caused by lack of fertilizer, use thin fertilizer and apply top dressing frequently. 4. Timely temperature control: If the temperature is low and causes frost damage, it is necessary to control the temperature as soon as possible to keep warm.

5. Replace the soil: If the pH of the soil is not suitable, change the soil as soon as possible.

1. Suitable lighting.

The yellowing of the leaves of flowers is most likely caused by poor lighting. If the light is too strong or the sun is not exposed to the sun for a long time, the plants cannot photosynthesize and will appear yellow. If the sun is too strong and you get sunburned, you should shade the sun as soon as possible and spray water frequently to promote the recovery of the plant.

If it is caused by long-term lack of sunlight, it is necessary to increase the light, and more astigmatism in the initial stage to give the plant an adaptation stage, and slowly increase the light.

2. Watering appropriately.

The yellowing of flower leaves may also be caused by a lack of water, which consumes a lot of water during the growth period, and there is no stagnant water to replenish the water, and the roots cannot absorb water, and the leaves will appear dry and yellow. If this is the case, it is recommended to water thoroughly as soon as possible so that the plants can absorb enough water and slowly resume growth.

3. Reasonable top dressing.

Flower plants consume a lot of nutrients during the growth period, if they are not topdressed for a long time, the soil is poor, and they cannot absorb the required nutrients, and they are prone to yellowing after a long time. If this situation is caused, it is recommended to top dressing as soon as possible, select suitable fertilizer varieties according to the growth stage, and use thin fertilizer to supplement fertilizer frequently, so as to promote the recovery of growth as soon as possible. Note that raw fertilizer must not be applied, otherwise it is easy to produce fertilizer damage.

Fourth, timely temperature control.

The cold tolerance of many flowers and plants is relatively poor, if the temperature can not be well controlled after winter, it is easy to frostbite if it is in a low temperature environment for a long time, resulting in yellow leaves. If it is low-temperature frostbite, it is necessary to raise the temperature and control the temperature in time to keep warm.

5. Replace the soil.

Flowers and plants are different, and the requirements for the soil are not high. Some plants prefer acidic soils, while others prefer alkaline soils. If the pH of the soil is not suitable or too sticky, it will hinder the respiration of the root system and cause yellow leaves.

The soil should be changed as soon as possible according to the growth habits of the plants to ensure that the soil is suitable.

1. Water the yellow leaves in time after the lack of water leads to thorough watering. 2. Yellow leaves caused by too strong sunlight need proper shading. 3. Yellow leaves caused by rotten roots need to be repotted and repaired, which can effectively remedy the yellow leaves of flowers.

The yellowing of the leaves is caused by insufficient nutrition. Top dressing outside the roots. Fertilization in this method is mainly to make up for the lack of nutrients in the soil, so as to solve the problem of lack of fertilizer in the plant, so that the seedlings grow fast and the flowers and fruits grow hypertrophied.

4.Extra-root fertilization is to spray the dilution of fertilizer directly on the leaf surface of the plant with a mist, so that the nutrients can penetrate into the leaf tissues through the leaf epidermal cells and stomata, and then be transported to the whole body of the plant. In this way, the leaves will be fully nutritious and will not turn yellow.

Remedies for yellowing of flowers and leaves: control the amount of water, adjust the soil quality, choose the right growth environment, prevent and control pests and diseases, and keep warm.

1. Control the amount of water

When the potting soil is in a state of too high water content for a long time, the lack of oxygen is not breathable, the flowers are difficult to breathe and absorb nutrients normally, the root system is easy to rot, and the leaves are yellow and falling.

2. Adjust the soil quality

Most of the flowers raised at home are suitable for growing in acidic soil, if the cultivation soil is alkaline, the plant will be due to the lack of soluble iron in the soil for growth, resulting in the gradual yellowing of the leaves, at this time it is necessary to add an appropriate amount of sulfur or pine needles to the soil, which can usually be watered with rice water after fermentation.

3. Growth environment

Flowers are easy to be infected with pests and diseases when placed in an unventilated and opaque environment between the slag holes for a long time, and the plants grow vigorously and are not pruned in time, which will lead to insufficient light in the inner branches and leaves, and cause yellowing of the leaves.

4. Prevention and control of pests and diseases

Flowers infected with leaf spot disease or scale insects will cause yellowing of leaves, yellow spots will appear on the leaf surface after infection with leaf spot disease, and in severe cases, it will cause the whole leaf to wither and fall off, and it is necessary to spray carbendazim ** leaf spot disease, after being infected with scale insects, the leaf surface will appear local yellowing and falling, and it is necessary to use scale spirit to apply to the leaves to eliminate pests.

5. Keep warm

Mild frostbite can recover slowly by moving to a warm location for maintenance; If frostbite is severe, the leaves that are severely frosted should be cut off, and the wound letter should be smeared with carbendazim sterilization, and all the leaves should be frostbitten "cut bald", and wait for it to sprout again.

There are various reasons for the yellowing of flowers and leaves, and you can choose the corresponding method to take care of them carefully.

1. Depotting and pruning

The yellowing of the flowers and leaves may be caused by improper watering, too much watering, causing the potting soil to be too wet, the leaves will lose their luster, they will become dark and yellow, and the flowers and leaves will gradually shrink, and even fall off. At this time, it is necessary to depot immediately and place it in a ventilated environment for drying.

2. Supplemental lighting

Plants need sufficient light to synthesize chlorophyll during the growth process, and if they are grown in a dark environment for a long time and lack of light, the plants will appear yellow. It needs to be transferred to a well-lit environment for maintenance, and after a period of time, the leaves will turn green.

3. Loose soil

Plants will consume a lot of nutrients in the growth process, which will lead to soil compaction, so that the root system can not normally deliver nutrients and water to the leaves, which will make the flowers and leaves appear yellow, and the soil needs to be loosened in time to create a good growth environment for the plants. In the later stage of maintenance, it is necessary to change the pot every 1 2 years to avoid the condition of soil compaction.

4. Dilute fertilizer

In the process of maintaining the plant, if the number of fertilization is too many times or the fertilizer concentration is too large, there will be a situation of excess nutrients, and the root system will be burned, and the leaves will appear yellow and fall off. At this time, it is necessary to water the soil in time to dilute the fertilizer in the soil, and transfer the plants to a ventilated and cool place for maintenance to speed up the evaporation of water.

5. Reasonable watering

If you water too little, it will cause the plant to have dull and aging leaves due to drought and lack of water. At this point, as long as normal watering is slowly resumed, the plant can return to its normal state.

The most direct and effective method is to spray the foliar powder potassium dihydrogen phosphate, which is very effective.

If you water too much, the new leaves at the top are pale yellow, the old leaves are gradually yellow, and the plants become shorter and shrivel. Living in an excessively wet soil environment for a long time, the roots are perishable.

Solution: Loosen the soil frequently, control watering, and move potted wisteria inside the house to avoid rain on rainy days. Soil drought is obviously a lack of watering.

The underground rhizomes cannot continue to grow because the soil is too dry and too hard, causing the lower leaves to age, but the top leaves grow normally. However, as time grows, the leaves will gradually turn yellow and fall off from the bottom up.

How to deal with it. Watering, of course! But don't water too much at once, increase it one by one, and water it thoroughly.

Lack of fertilizer & fertilizer damage.

The symptoms of improper fertilization are: the leaves are thin and yellow, and the surface is uneven and uneven. If you don't fertilize for a long time or apply too much fertilizer, the roots can't grow properly.

Solution: Fertilize properly and repot at the right time. When the plant grows slowly, the liquid fertilizer should be replenished in time. However, if the dosage is not controlled, it is necessary to water in time to dilute the fertility to avoid causing fertilizer damage, and you can use Ribery Yanwo water-soluble fertilizer.
