What to do with gardenia yellow leaves It is very yellow, but the veins of the leaves are green

1. Soil. It is necessary to choose loam soil with good permeability, good water and fertilizer retention. 2. Temperature.

Gardenia in 20-25 is its optimal growth and development temperature, flowering temperature is 26-28, after 4-5 years of cultivation of plants, can tolerate a short period of -3 low temperature, -5 below that suffer frost damage, leaves black after falling off, young shoots freeze to death. In winter, indoor maintenance should be maintained at 6-10 degrees, and the minimum should not be less than 0. If the room temperature is higher than 15, the south-facing doors and windows should be opened, properly ventilated, and the temperature should be reduced, otherwise it is easy to cause germination, and it will be harmed by low temperature, which is extremely unfavorable to the growth and flowering of the next year.

3. Illumination. Gardenias like abundant light, especially in spring and autumn, to give more than 8 hours of sunshine a day, otherwise it is not conducive to its growth and development and winter overwintering. In summer, avoid strong light exposure at noon, otherwise the leaves will turn yellow, and it is necessary to place astigmatism for maintenance, and the light transmittance is 40-50.

In winter, it is placed indoors in direct sunlight facing south. 4. Fertilization. Gardenia is not a very fattening flower, but because it grows vigorously and is limited by the nutrients of potting soil, it needs to be reasonably supplemented with fertilizer during the growth period.

Apply rotten human manure or cake fertilizer every 10 days or so, stop watering 1 day before fertilization, and water once at the same time on the day of fertilization. Fertilization will be stopped from mid-September. For adult plants, apply sesame paste residue once in mid-June and mid-August, two at a time, and mix well with the topsoil after crushing.

5. Watering. Gardenias like big water, and some people call it "water gardenia". In spring, due to the windy winds, dry air and scarce rainfall, water is watered every 3 days, and water is sprinkled every morning and evening around the potted plants to increase air humidity.

In summer, when the weather is hot, it is necessary to water less in the morning and water thoroughly after 2 o'clock in the afternoon. In summer, it is advisable to water with soft water, because the hard water contains more calcium and magnesium salts, which is very unfavorable to the growth of gardenias. In order to overcome the alkalinity of the soil and water quality, alum fertilizer is watered once a week during the growing season to keep the gardenia branches and leaves thick.

Watering should be controlled in winter, not dry or watering, long-term excessive water content, easy to cause root rot and death. 6. Topping. In order to regulate and control the growth of gardenias, make the plant beautiful and promote flowering, the tips of new branches are removed in the spring when vigorous growth is about to stop, and the axillary buds at the base of the branches are full and the flower buds are full.

Gardenia yellow leaves, 3 reasons, the right medicine, yellow leaves soon green back.

1. Excessive watering, this kind of situation is more common, one is the old leaf yellow caused by the new water. The newly purchased gardenia has yellow leaves at the bottom, the veins are still green, and the edges are yellow, many of which are caused by changing the environment. Remove the yellow leaves and wait for the new leaves to grow.

The other is that the young leaves are dark yellow and dull, the old leaves have no obvious changes, the branches are small yellow-green, and the new shoots are shrunk and not long, indicating excessive watering. Solution: Depot the gardenia and put it in a ventilated and cool place to dry the soil and then put it back into the pot.

2. Watering too little, not watering gardenias for a long time, due to lack of water, will cause gardenia leaves to turn yellow. Generally, the leaf tips or edges are withered and dry, and the old leaves are yellow and fall off from the bottom to the top, but the growth of new leaves is relatively normal. Treatment method: Pay attention to watering thoroughly when watering.

3. Excessive fertilization, that is, due to excessive or too concentrated fertilization, the gardenia leaves are yellow, and the general symptoms are: the leaf veins lose green and turn yellow, while the surrounding area is still green. There is also the sudden overall loss of green, dry and yellow leaves after fertilization, which are caused by hypertrophy and fattening.

Treatment method: irrigate the roots with large water and depot and wash the roots. In the absence of fertilizer, yellow leaves are manifested in the color of young leaves becoming lighter, yellow or light green, while old leaves are more normal or gradually turning from green to yellow.

Treatment method: check the potting soil, if there is a dry knot phenomenon, the soil should be replaced, usually thin fertilizer is applied diligently and some alum water is poured in a timely manner, and the general problem can be solved.

Precautions: Gardenias, summer should avoid direct sunlight, suitable for living in a slightly shaded place, strong direct sunlight will cause the flower leaf tips, leaf edges withered, leaf sunrise part of the yellow spots. However, if it is placed in a shady environment for a long time, the leaves will not get enough sunlight to form chlorophyll, and the whole leaf will turn yellow and then fall off.

Gardenia leaves yellow? 2 "tricks" to solve, the leaves are green, and the flowers are numerous.

Analysis of the causes of yellowing of gardenia leaves:

1) Factors of improper moisture.

Gardenia planting process watering too much, then the young leaves will be dull, the old leaves will not be affected, but the leaves will be yellow-green, the new leaves are not long, the solution is: depot the flowers in a ventilated and cool place to dry the soil and then put back into the pot. When there is a lack of water, the leaf tips or edges are withered and dry, the old leaves are yellow and fall off from the bottom to the top, and the growth of new leaves is relatively normal.

2) Factors of improper lighting.

If the gardenia is placed in a shaded environment for a long time, then the leaves will turn yellow or fall off because they do not get enough sunlight, so it is best to supplement the light immediately.

3) Factors of improper fertilization.

Gardenia planting process fertilization should pay attention to, too much or too much concentration is easy to cause plant yellowing, the tip of the new leaf will appear brown, generally the leaf surface is thick and dull, and uneven and uneven, the old leaves are scorched and fall off. At this time, more water should be used to reduce the concentration of soil fertilizer. Insufficient fertilizer can also cause yellowing of plants, but the nutrients that are lacking in the plants are different, and the symptoms are different.

Nitrogen deficiency: The plants are short of nitrogen and the leaves are yellow, and the new leaves are small and brittle.

Potassium deficiency: When a plant is deficient in potassium, the old leaves turn from green to brown.

Iron deficiency: At the beginning, the leaves are pale yellow or white, and the veins are still green, and in severe cases, the veins are also yellow or white, and eventually the leaves dry up and die. In this case, the aqueous solution of ferrous sulfate that can be sprayed can be prevented.

Magnesium deficiency: yellowing begins to develop from old leaves to new leaves, and the leaf veins are still green, and the leaves fall off and die in severe cases. It can be sprayed with 7%-8% boron and magnesium fertilizer for control.

Phosphorus deficiency: The old leaves are purplish-red or dark red.

During the growth of gardenias, the leaves often turn yellow, and the reason is mostly caused by poor cultivation management. Too much water, too little sunlight, too much or too little fertilizer will cause yellowing of leaves, but the yellowing situation is different, and the causes should be carefully observed and analyzed, and corrected.

Water yellow The young leaves are dark yellow and dull, the old leaves have no obvious changes, the branches are small yellow-green, and the new shoots are shrunk and not long, indicating excessive watering. Depot the flowers, put them in a ventilated and cool shade, and dry the soil ball before putting them back into the pot.

Dry yellow The yellow of lack of water is different from the yellow of more water, the yellow of lack of water is the withering and dry leaf tips or edges, and the old leaves are withered and yellow from the bottom to the top, but the growth of new leaves is relatively normal. Pay attention to watering when watering enough, water thoroughly.

Burning yellow strong sunlight directly on some shade-loving flowers (such as spider plant, hosta, etc.) is easy to cause the leaf tips and leaf margins of flowers to wither, and the sunny part of the leaves appears yellow spots. Move to the pubic area.

Lack of light yellow long-term shade environment, the leaves do not get enough sunlight, can not form chlorophyll, the whole leaf turns yellow and then falls off, supplemental light can avoid this disease.

Yellowing of flowers caused by excessive fertilization or excessive concentration is manifested in the appearance of dry brown at the top of the new leaves, and the general leaf surface is thick and dull, and the concave and convex are not stretched, and the old leaves are scorched and peeled off. Fertilization should be stopped immediately, and part of the fertilizer should be washed with plenty of washing in severe cases.

Lack of fat yellow is manifested in the color of young leaves becoming lighter, yellow or light green, while old leaves are more normal or gradually turning from green to yellow. Check the potting soil, if there is a dry knot, the soil should be changed, and the thin fertilizer should be applied frequently and some alum water should be poured in a timely manner.

1. What to do if the gardenia leaves are green and the leaves are yellow.

2. What's going on with the green veins and yellow leaves of gardenias.

3. The veins of gardenia leaves are yellow.

4. What is the problem with the yellowing of the leaf veins of gardenias.

1.The gardenia has green veins and yellow leaves, probably because of the lack of sunlight in the environment in which it is raised.

2.At this time, it should be relocated to a better place to raise.

3.It may also be because it is watered too much water when raising it, at this time it is necessary to depot it, cut off the rotten roots, and then plant it in new soil and slowly maintain it.

4.It may also be because it is deficient in iron, and at this time, it should be supplemented with some low-concentration ferrous sulfate solution to supplement iron.

In addition to the yellowing of the leaf veins of gardenia leaves, it is caused by the appropriate environment, such as improper moisture, improper light, improper fertilization, etc., so let's introduce the solution in detail.

1. Slowly adapt to the environment.

Gardenia just bought back or just changed the maintenance position, generally moved out from the higher temperature position, gardenia to the new environment, if the environmental difference is too large, it will cause yellow leaves, which is an uncontrollable factor, so the yellowing of the leaves is observed for a period of time, during which it needs to be well maintained.

2. Reasonable watering.

If you don't water often, resulting in a lack of water in gardenias, it may cause gardenia yellow leaves, and in addition to watering in the planting process should not be too much, too much water in the pot will cause the pot soil to be too wet, which will cause the young leaves to be dull, slow growth, and the old leaves are yellow-green, gradually withering.

3. Pruning and maintenance.

Gardenia is a woody stem, when the yellow leaves appear, the yellowed branches and leaves should be cut off directly, which can ensure the normal growth of the trunk, careful maintenance, and soon after, new leaves will grow, the gardenia maintained indoors needs to be maintained and ventilated frequently, to ensure that the location of the environment is bright, and the plant is placed by the window for maintenance.

First of all, see if the soil is moist or dry, determine whether there is a lack of water, and also need to be placed in a ventilated place, with sunlight is the best.

1. Overwatering.

When the soil is clay and not loose and breathable, it is easy to accumulate water if it is watered too much, resulting in dark yellow and dull young leaves of gardenia, but no obvious change in old leaves. At this time, it is necessary to place the pot in a ventilated and cool place, wait for the soil to dry and then put it in a suitable position, and it is best to replace it with a loose and breathable substrate for cultivation.

2. The light is too strong.

If the yellow spots appear on the sunny part of the leaves, they only need to be moved to the shade to be maintained, and the newly grown leaves will no longer have yellow spots.

3. Excessive fertilization.

It is mainly manifested in the appearance of brown at the top of the new leaves, the leaf surface is thick and dull, and the old leaves are charred and peeled off. At this time, it is necessary to stop fertilizing immediately, and in severe cases, rinse the soil to reduce the concentration.

The yellowing and shedding of gardenia leaves may be caused by the discomfort of the potting soil. It is loose and slightly acidic soil. If the soil is heavily compacted or too alkaline, it will lead to poor growth and leaf changes.

When watering, an appropriate amount of ferrous sulfate should be added to maintain acidity, and it is recommended to change the soil in severe cases. It may also be overwatering, and it is easy to accumulate water and rot the roots, so that the leaves will also yellow and dry up. Attention should be paid to reducing the amount of water, as long as it is slightly wet during the growing season, and no water should be accumulated.

Does the new leaf start to yellow, or do it start with the old one? Is it a disease or a lack of fertilizer? Judge for yourself first, and then you can prescribe the right medicine.

Friends who have raised gardenias know that gardenias are very easy to yellowing leaves, there are many reasons, a flower friend who has raised gardenias for 10 years, summarized some of the reasons why gardenia leaves are yellow, you can compare them according to your own situation, and then solve them in a targeted manner, you can do not ask for people, and you can also solve the problem of yellow leaves.

1. Overwatering.

The manifestations are: the yellowing of the leaves is from bottom to top, the old leaves are yellow first, the leaf veins are green, and then gradually the whole area is yellow.

Low temperature water yellow. Causes: Poor indoor ventilation. The potting soil is too sticky, too fine, permeable, and has poor air permeability, as well as good soil moisture retention and excessive watering. Watering the bubble pot too often. Sudden cooling of the soil when it is wet.

The potting soil is too sticky, resulting in a lot of water.

The new pot is too large, the new fill layer is too thick, and the root system of gardenia in the slow seedling stage cannot reach the edge of the pot. The branches and leaves at the bottom layer are too dense, which affects the ventilation of the soil surface. Sandwich soil, the outer layer of loess in the nutrient soil in the new pot, or the inner loess and the outer nutrient soil.

Extremely cold air-conditioned room in summer. Flower pots have poor air permeability and poor heat dissipation.

You can judge according to your own situation, it may be caused by one reason, or it may be caused by multiple reasons, and then you can determine how to solve it.

2. Excessive fertilization.

The performance is that the veins of the old leaves of gardenia are yellow, but the surrounding area is still green.

Cause: The concentration of fertilizer applied to gardenias is too large.

Solution: If you find this situation, you should change the water blister pot (many times) as soon as possible, or irrigate the roots, that is, use very fine water to water all the time, about half an hour, the purpose is to dilute the overly concentrated fertilizer in the soil.

3. Iron deficiency yellow.

The manifestations are: the new leaves of gardenia are yellow, specifically the veins are green, and the mesophyll is white-green.

Cause: Lack of iron.

Solution: Use alum fertilizer water (ferrous sulfate, dried manure, cake fertilizer and water, press 1:3:

The ratio of 5:100 is prepared, and the black-green liquid becomes after full fermentation) or ferrous sulfate and white vinegar spray leaves or direct watering, the effect of alum fertilizer water is obvious, and the roots are significantly improved after a few days.

4. The soil is alkaline.

Most flowers in the south prefer acidic soils, while the soil in the north is alkaline, which will cause the gardenias from the south to suffer from alkali damage and cause yellowing of leaves.

Solution: Replace the cultivation soil with peaty soil or sulfur powder. These southern flowers and trees should be watered with ferrous sulfate once a week; Keep the potting soil loose and drained smoothly; Or soak the grass in water, and after the grass rots, water the flowers with supernatant to reduce the occurrence of alkali damage.

5. Hard water in the north.

In addition, most of the water in the north is hard water (refers to water containing more soluble calcium and magnesium compounds), and the common use of hard water to water flowers will promote the increase of lime content in the soil and compaction, which is not conducive to the growth of the root system, and at the same time cause the leaves to gradually turn yellow and wither.

Solution: Vinegar water can be poured 1 time every 2 3 weeks, or it can be sprayed on the plants by adding 2 tablespoons of vinegar to 1 liter of water, which can prevent the leaves of gardenias in the south from yellowing and make them grow better.

6. Other reasons.

The two new leaves are obviously tender and yellow, which is a lack of fertilizer.

Nematodes invade the root system, causing malnutrition and drought yellow.
