What s going on with the new leaves of the gardenia all turning yellow.

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 not the same as 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 shines on some shade-loving flowers (such as spider plant, hosta, etc.), which is easy to cause the leaf tips and leaf edges of flowers to wither, and the sunny part of the leaves to appear yellow spots. Move to the pubic area.

Lack of light yellow: If the leaves are shaded for a long time, the leaves cannot get enough sunlight to form chlorophyll, and the whole leaves turn yellow and then fall off, and the disease can be avoided by supplementing light.

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

Lack of fat yellow: It 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.

In winter, gardenias are easy to appear yellow leaves, too much watering is the main reason for the yellow leaves of gardenias, gardenia young leaves are dark yellow and no luster, but there are no obvious signs of yellowing around the old leaves, most likely is watering too much, once this happens, it is necessary to move the gardenia to a well-ventilated and will not be exposed to the sun to maintain it, so that it volatilizes excess water.

1.Improper moisture.

2.Too much watering, in this case, the young leaves of the mast flowers are dark yellow and dull, but the old leaves have no obvious changes, at this time, as long as the flowers are taken out of the pot and placed in a ventilated and cool place, and then put back after the soil is dry.

3.Lack of water, leaf tips or edges withered and dry, old leaves from the bottom to the top withered and yellow, but in this case, the growth of new leaves is relatively normal.

4.Improper lighting.

5.If the light is too strong, the sunny part of the leaf will appear yellow spots, and then it only needs to be moved to the shade to be maintained, and the newly grown leaves will no longer have yellow spots.

1. Too much watering causes the leaves of the mast flower to turn yellow (water yellow): If the seed flower is planted with too much watering, then the young leaves will be dull, and the old leaves will not be affected, but the leaves will be yellow-green, and the new leaves will not grow.

Solution: Unpot the flowers in a ventilated and cool place and put them back into the pot after the soil is dry. 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. Excessive fertilization of mast flowers causes the leaves to turn yellow (fat yellow): the leaf veins lose green and turn yellow, but 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.

Solution: What kind of fertilizer is good for gardenias, rotten human feces or cake fertilizer are good choices. So far, there are only two ways to deal with fat yellow: irrigating the roots with large water and removing pots and washing the roots.

3. Poor ventilation leads to yellowing of mast leaves (burning yellow): The environment in which gardenias grow needs to be ventilated and moist and brightly lit. If the windows are not opened often, there will also be signs of yellowing of the leaves.

Solution: Remember to open windows every day for ventilation.

4. Lack of fertilization of mast flowers leads to yellowing of leaves (fertilizer yellow): insufficient fertilizer, insufficient fertilizer will also cause yellowing of plants, such as iron deficiency, leaves are pale yellow or white, and leaf veins are still green.

Solution: Ferrous sulfate water to be sprayed for control; Magnesium deficiency, first the old leaves yellow, then the new leaves yellow, the leaf veins are still green, then you can spray a boron magnesium fertilizer to control.

5. Improper light causes yellowing of mast flower leaves: If the light is too strong, yellow spots appear on the sunny part of the leaves.

Solution: The mast flowers need to be moved to the shade to be maintained, and the newly grown leaves will no longer have yellow spots. If there is not enough sunlight, the leaves will turn yellow or even fall off.

Gardenia is an acid-loving plant, in addition to watering, fertilizer and other factors will cause gardenia yellow leaves, there is also a yellow leaf reason: iron deficiency yellow leaves, in daily watering can add ferrous sulfate with water to water gardenias, can effectively avoid iron deficiency yellow leaves.

The yellowing of gardenia leaves is due to too much water, insufficient nutrients, and too low temperature.

1. Too much water.

Gardenias prefer to grow in a moist environment in the early chain, but it is not tolerant to waterlogging, and its leaves are prone to yellowing if it is overwatered or the air humidity is too high.

2. Insufficient nutrients in bridge hail.

The yellowing of gardenia leaves may also be caused by a lack of nutrients, and if it lacks iron, the plant will not be able to synthesize chlorophyll, so it will turn yellow. If magnesium is deficient, the leaves of the plant will also turn yellow.

3. The temperature is too low.

Gardenias prefer to grow in warm environments, it is not tolerant to low temperatures, and if the temperature is too low, it will cause frost damage to the plant, and its leaves will also turn yellow.

How to care for gardenias

In view of the problem of excessive moisture, it is generally necessary to do a good job in ventilation management, usually open windows frequently, facilitate air circulation, let the excess water evaporate quickly, and then also need to control watering, each time the amount of water does not have to be too much, keep the soil slightly moist. In view of the problem of nutrient insufficiency, iron deficiency can be sprayed with ferrous sulfate aqueous solution for prevention and control, and magnesium deficiency can be sprayed with minsuifan boron magnesium fertilizer for prevention and control.

In view of the problem of low temperature, it is necessary to take warm measures in winter, it is best to move the gardenia to a warm place indoors for maintenance, it is recommended to put it in the bedroom, so that when the heating or air conditioning is turned on, you can take care of the needs of gardenia insulation, and you can also freshen the air in the bedroom and smell the fragrance of gardenia at any time.

I also raised gardenias - but you watered too often, now this season; Every 7-10 days, 3-5 days in summer - keep it dry and wet - in spring it needs more nutrients in order to germinate new shoots, and fertilizer can be mixed with ferrous sulfate

Once every 7-10 days - let the flowers bloom big and fragrant, spray the dilution of potassium dihydrogen phosphate once a week as foliar fertilizer.

Listen to me, you can't be wrong - sometimes the book is inaccurate -

You have to slowly explore the experience on your own.

Gardenia is an acid-loving flower, the new leaves turn yellow is not necessarily a lack of water, you can buy some ferrous sulfate diluted with water and water the flowers, once in ten days, after normal, and then spray the foliar surface with potassium dihydrogen phosphate solution Remember: be sure to apply thin fertilizer frequently

Gardenia especially needs iron moisture, iron deficiency will get yellowing, first manifested on the new leaves, beginning to be pale yellow or yellowish-white, the leaf veins are still green, slowly the leaves will fall off and die. In terms of management, it is necessary to pay attention to keeping the soil moist, and the diligent people are well decomposed and thinly fertilized. When turning over the pot and changing the soil, the fertile and loose acidic soil should be used, the base fertilizer should be sufficient, and the foliar spray of potassium dihydrogen phosphate 1000 times should be carried out once a week; Aqueous ferrous sulfate solution should also be sprayed frequently to prevent iron deficiency yellowing.

If the gardenia starts to turn yellow in a short period of time, it is often caused by too much water. Although gardenias are flowers that like moist environments, if they are watered too much, too much water in the pot will cause less air in the soil and the root system will be injured, which can make the leaves yellow. Therefore, special care should be taken during the maintenance process.

If the pot used is not well permeable, the water evaporates very slowly, which will cause great harm to the root system of the gardenia, and if the root system is not good, the leaves will turn yellow.

In addition, gardenia is a positive flower, temporarily placed indoors is acceptable, for a long time without sunlight, unable to photosynthesize, the leaves will turn yellow. Therefore, gardenias must be maintained outdoors in full sunlight as much as possible.

Most of the causes of gardenia yellow leaves are caused by improper management in the cultivation process, such as too much water or insufficient water, too strong or too weak sunlight, too much fertilizer or lack of nutrients. We can only solve the problem of yellow leaves by figuring out the causes of yellow leaves, but how can we know what specific causes of yellow leaves?

Gardenia (details).

1. Caused by excessive water: the leaves are yellow, the young leaves are dark yellow and have no luster, but the old leaves have not changed much, and the new shoots have shrunk but do not grow.

Solution: Place the flowers in a ventilated and cool place, and wait for the excess moisture in the soil to dry out on its own before putting them back in place.

2. Yellow leaves caused by insufficient water: dry yellow, mainly in disguise: the leaf sheath is withered, the old leaves are first yellow and finally fall off, and the growth of young leaves is not greatly affected.

Solution: Since it is caused by lack of water, of course, it is to replenish the water, but pay attention to a certain degree in the process.

3. Yellow leaves caused by too strong sunlight: burning yellow, manifested as leaf sheath or leaf edge wilting, and yellow spots will appear on sunny leaves.

Solution: Move the flowers to the shade.

4. Yellow leaves caused by lack of sunlight: lack of light yellow, because the flowers are hidden in a dark place for a long time, resulting in their inability to synthesize chlorophyll, and finally the leaves are yellow and fall off.

The solution: move the flowers to a sunny place.

5. Yellow leaves caused by overnutrition: the top of the new leaves appears dry brown, and the leaves are yellow and dull.

The solution: stop fertilizing.

6. Yellow leaves caused by nutritional insufficiency: the color of young leaves gradually fades, and finally yellow.

The solution: fertilize the flowers.

The yellow leaves are caused by malnutrition or lack of water, and it is okay to apply some fertilizer to it.

Too much watering is caused by 2 alkaline water quality.

This is a lack of potassium, and it is OK to supplement some potassium fertilizer.
