What should I do if the gardenia is burned and some of the leaves turn yellow after the green manure

Gardenia leaves are yellow, three reasons "the right medicine", evergreen and fierce leaves in all seasons.

This phenomenon occurs because the fertilizer concentration is too high and burns the plants, and the most effective way to do this is to change the cultivation soil for the gardenia and water the gardenia more water, which can dilute the fertilizer and save the gardenia.

For gardenia with serious root burning, first cut off the upper part of the branches and leaves, then rinse the soil to remove the roots with clean water, prune the roots, soak them in clean water for 6 10 hours, pour mud on the roots, and add rooting powder and a little superphosphate to the mud.

It may be caused by adding too much fertilizer, so we can choose to water more, and then prune the roots of the gardenia, and in severe cases, we can replace the gardenia with new soil.

At this time, more water should be used to reduce the concentration of soil fertilizer.

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 lack or too much concentration is easy to cause plant yellowing, the top of the new leaves will appear brown, generally the leaf surface is thick and dull, and uneven and uneven, the old leaves are scorched and yellow. At this time, you should water more 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 leaf burning posture is pale yellow or white, the leaf veins are still green, and in severe cases, the leaf veins are also yellow or white, and finally 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.

4) Factors that are too low in temperature. Too low a temperature can also cause yellowing of leaves, so in the process of cultivating gardenias, we should pay attention to anti-freezing in winter, and we should also pay attention to keeping warm in the evening in early spring and early winter.

Regarding the problem of yellowing gardenia leaves, I will share this with you today, I hope it can bring you some help!

Analysis of yellowing of gardenia leaves:

1) Factors of improper water: If the gardenia is watered too much during planting, the young leaves will become dull, and the old leaves will not be affected, but the leaves are yellow-green, and the new leaves will not grow. The solution is to remove the flowers from the pot in a ventilated and shady place and return them to the pot after the soil has dried.

When there is a lack of water, the tips or edges of the leaves will become dry and dry, the old leaves will turn yellow and fall from the bottom up, and the growth of new leaves will be relatively normal. At this time, you should water and water thoroughly.

2) Factors of improper lighting: Excessive light can produce yellow spots on the illuminated surface of the leaves, which can be restored by placing them in a dark place. If the gardenia is left in a cool environment for a long time, the leaves will be affected.

It's best to replenish the light as soon as you get enough sunlight to cause it to turn yellow or fall off.

3) Factors of improper fertilization: Pay attention to fertilization during gardenia planting. Too high or too high a concentration can easily turn the plant yellow.

The top of the new leaf will appear brown. Usually, the leaf surface is thick, blunt, and uneven. Stretching, the old leaves turn brown and fall.

At this time, more watering should be done to reduce the soil fertility concentration. Insufficient fertilizers can also cause yellowing of plants, but nutrient deficiencies in plants are different and the symptoms are different.

Nitrogen deficiency: The nitrogen deficiency of plants only causes the leaves to turn yellow, while 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 first, the leaves are pale yellow or white, and the veins are still green. In severe cases, the veins are also yellow or white, and finally the leaves dry out and die. In this case, an aqueous solution of ferrous sulfate can be sprayed for prevention and control.

Magnesium deficiency: From old leaves to new leaves, the veins will still turn green, and the leaves will fall off and die. It can be sprayed with 7 -8 boron magnesium fertilizer for control.

Phosphorus deficiency: The old leaves are purple or dark red.

4) Factors of too low temperature: too low temperature will also cause yellowing of leaves, so in the process of gardenia planting, attention should be paid to winter frost protection, and in early spring and early winter night to keep warm.

About the yellowing of gardenia leaves, will be shared with you and hope to help you.

In such a situation, you should water and fertilize in time, and you should also put on some pesticides as soon as possible, so as to avoid insect infestation.

I think you should ventilate in time, lift up the plastic sheeting in the greenhouse, and after one night, the concentration of fertilizer will be reduced on the second day.

Ferrous sulfate can be sprayed with 0.2 to 0.5 percent of the ferrous sulfate to prevent and control the yellowing of the method.

Watering. Water can dilute the concentration of fertilizer and will not be so harmful to plants.

Gardenia leaves are yellow, take a look here before fertilizing, she shares the fertilization method.

If it is liquid fertilizer, immediately dilute the soil fertilizer with large water, wash it several times in a row, and then dry the soil as soon as possible to prevent waterlogging. If it is a solid fertilizer, dig it all out to avoid further development damage.

It is not necessarily that there is more water, it may be that the potting soil is alkaline, and ferrous sulfate solution can be added.

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

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.

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.

In addition, the phenomenon of gardenia yellow leaves is divided into: water yellow, dry yellow, burning yellow, lack of light yellow, fat yellow, lack of fat yellow six situations, first of all, let's introduce water yellow and dry yellow. The performance of water yellow is that the young leaves are dark yellow and dull, but there is no obvious change in the old leaves, the branches themselves are small and yellow-green, and the new shoots have not grown, this phenomenon indicates that the water is too much, and the solution at this time is to put the flowers off the pot in a ventilated and cool place, and then put it back into the pot after drying the soil mass; The performance of dry yellow is that the leaf tips or edges are dry, and the old leaves are withered and yellow from the bottom to the top, but the growth of new leaves is relatively normal.

The next is the introduction of the gardenia yellow leaf phenomenon in the phenomenon of burning yellow and lack of light yellow solution, many people may think that water yellow and burning yellow are opposite, in fact, gardenia is a shade-loving plant, strong sunlight directly to some shade-loving flowers (such as spider plant, hosta and the like), it is easy to cause the leaf tips of the flower, leaf edge withered, the leaf sunrise part of the leaf yellow spot, the solution is of course to move to the shade; As the name suggests, the lack of light yellow is placed in a shady environment for a long time, and the leaves do not get enough sunlight to form chlorophyll, so the whole leaf will turn yellow and then fall off, at this time, as long as the light can be supplemented, the disease can be avoided.

In short, the yellow is the yellow leaves of gardenia caused by excessive fertilization or excessive concentration, the main symptoms are dry brown at the tip of the new leaves, the leaf surface is thick but not dull, the old leaves are scorched and fall off, at this time, it is necessary to stop fertilization immediately, and if it is serious, wash off part of the fertilizer with a large amount of cleaning; The lack of fertilizer yellow is manifested in the color of the young leaves become lighter, and the old leaves are more normal or gradually turn from green to yellow, what to do is to check the petri dish, if there is a dry knot phenomenon, the soil should be changed immediately, and the usual fertilization should be done to make the gardenia "eat less and eat more" and properly water some alum water.

Gardenia is easy to yellow leaves if it is not properly maintained, and organic fertilizer is used, the nutrients are sufficient, and the branches and buds grow faster.

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

Gardenia diseases and insects are very few, only physiological diseases lack green disease, which generally occurs when cultivating with alkaline soil, the leaves turn yellow at the beginning of this disease, and even the branches and leaves are scorched, the flowers are scarce, and finally cause the death of the whole plant. Alum fertilizer water can be applied to prevent and control. (ferrous sulfate).

Gardenia yellow leaves, generally because of long-term watering alkaline water or the application of alkaline fertilizer caused by the high pH value of the soil, it is recommended to water some ferrous sulfate solution, ferrous sulfate can be bought in the general flower, bird, fish and insect market.

You can sell flower fertilizer in the flower and bird market, but be careful when you put it, don't put it at the roots, and the roots of the tree will die.

Gardenia yellow leaves, dry leaves can be caused by a variety of reasons, including stuffy roots, fertilizer, nutrient deficiencies, pests and diseases, etc.

Stuffy roots refer to the inability of plants to absorb water and nutrients normally due to excessive humidity and poor aeration of plant roots, resulting in yellow leaves and dry leaves.

Fertilizer damage refers to the disease caused by excessive fertilizer absorption or improper fertilization of plants, usually yellowing, scorching, wilting and other conditions of leaves.

If you notice that the leaves of your gardenia are dry, you can check whether the roots of the plant are too wet and if there are ventilation problems; In addition, it is also necessary to pay attention to whether the amount and application method of fertilizer are correct to avoid excessive fertilization. If the above methods cannot be improved, you can find a professional to check whether there are other problems such as pests and diseases.
