Gardenia every ten days and half a month a few leaves turn yellow and fall, is this normal?

Yellowing of leaves is one of the common diseases of gardenias, and many factors can cause gardenia yellowing.

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.

It's common, mine is the same, and today it's blooming again, hehehe.

In November, gardenias will fall their leaves, although this plant is an evergreen shrub, but it is still the same as a normal plant, because of the growth of the year, the life of the leaves and other reasons to drop a small number of old leaves, this is a normal phenomenon, but if the leaves fall off in large pieces, then there may be a problem with the plant.

It could be these reasons:

1. Soil compaction: If there is a large area of defoliation in gardenias, it is most likely that there is a problem with the soil, such as salinization caused by the accumulation of inorganic salts caused by excessive fertilization and too frequent fertilization, or the compaction phenomenon that has not been turned over for a long time, which needs to be replaced in time with loose and fertile acidic new soil. And use avoiding microbial agents to improve the soil to ensure normal growth in the future.

2. Excessive watering: too much watering will also lead to a large area of leaves of the plant falling off, generally speaking, when watering gardenias, it is necessary to abide by the principle of seeing dry and wet, watering until the soil is slightly moist, it is necessary to pay attention to not leaving stagnant water, if the stagnant water is left and the plant has a rotten root phenomenon, the leaves of the plant will fall off.

3. The temperature is too low: Gardenia has a certain ability to resist cold, generally speaking, it can survive normally at about zero degrees, but if it is exposed to sub-zero low temperature for a long time, or is blown by cold wind, the plant will be prone to leaf loss, so it should be moved indoors or covered in time.

The reasons for the yellowing and defoliation of gardenia leaves are as follows:

1. Hurt the root system of the flower when changing the pot.

If you hurt the root system of your own flowers when changing pots, it will affect the growth of gardenias after changing pots. If it is because of this that the yellow leaves are caused, you must first maintain your root system so that it can restore its green leaves.

2. The potting soil is not suitable.

Gardenias like more fertile, well-drained, lightly clay soil, if the soil is not suitable when changing pots, it will lead to yellow leaves and leaves, at this time it is necessary to wash the roots of the gardenia, so that its roots do not stick to the previous soil, and then replace it with the soil he likes.

3. Improper watering.

After changing the pot, you need to water your own flowers, and you need to water them thoroughly, but if you don't water them thoroughly in time, the leaves will be yellow and fall. Improper watering is also a significant cause of gardenia death.

4. Soil waterlogging.

Gardenias like to live in loose and breathable soil, if watered frequently, it will cause the roots of gardenia to not breathe smoothly, just like someone covered our nose when we breathe, over time, the reaction to the leaves is yellow leaves.

5. Iron deficiency. Gardenias have a high demand for iron compared to ordinary flower plants, and if we maintain the soil used for gardenias, if there is less iron, it is likely to appear in the case of yellow leaves.

Gardenia is an evergreen shrub in the Rubiaceae family. Lack of sufficient nutrients during the growth process, some parts of the gardenia are underdeveloped, which will lead to problems such as yellowing of leaves, rotten leaves, and wilting leaves. Attacks such as leaf spot, leaf blight, stem rot, etc., can cause the leaves of gardenias to turn yellow.

Sometimes, when gardenias are attacked by diseases and insects, the leaves will also turn yellow and wilt. Generally, the yellowing of gardenia leaves is caused by insufficient nutrition.

Recommendation: Root topdressing. 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.

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.

Precautions for gardenia cultivation

Gardenias will grow flower buds in spring, and fertilization can be done with potassium dihydrogen phosphate fertilizer based on phosphorus and potassium elements, about once a week, which can promote the differentiation of flower buds until the flower buds are formed. No fertilization is applied during flowering, and potassium dihydrogen phosphate can be used once after flowering, which is helpful for later growth.

The main pruning time of gardenias is during the growth period from May to July and the dormant period around December, and there is no need to overprune the two stages. When the growth is relatively vigorous, the branches and leaves that are too long, too dense, and have poor growth can be cut off, which look very messy and affect the growth and ornamentation of the branches and leaves should also be pruned appropriately.

After the plant has buds, it is necessary to remove the buds that are not growing well, and keep the strong buds to ensure the quality of flowering, so that the plants can bloom large and full.

The yellowing of gardenia leaves is usually caused by overwatering.

At this time, you should stop watering and remove the yellow leaves from the branches. When planting gardenias, it is important not to let there be stagnant water in the pot when watering, so it should be watered many times and in small amounts.

If the gardenia has just been bought, and the yellow leaves appear without too much watering, it may be a lack of fertilizer, and some ferrous sulfate plant fertilizers can be purchased to apply. Gardenias are leafy plants and should be placed in a well-lit and well-ventilated environment.

This situation is caused by excess fertility, and it is only necessary to replace the soil in the pot.

Prune the branches, remove the yellow leaves, if the soil in the pot is compacted, loosen the soil around the pot, if the soil is not good, replace it with 6:3:1 sand, garden soil, coconut peat soil, water thoroughly after changing the pot (don't do this in winter), put it on the balcony in a half-shaded and half-sunny place, keep ventilation and ventilation, and wait for the potting soil to dry to seven or eight percent before watering.

Although gardenias like to have plenty of light, due to the change in the breeding environment, too early exposure to the sun will cause the leaves to lose water and turn yellow.

Watering too much, add powdered organic fertilizer to water for ten days, water thoroughly in a flash, and water once every ten days.

Be sure to water regularly, pay attention to the sun, and ventilate in a timely manner, and don't always keep the plants in a cool, damp place.

Gardenia yellow leaves, this first means that there is a problem with the potting soil, indicating that your gardenia has not changed the soil for a long time, or that the potting soil of your original gardenia is also a general flower soil, and the quality is not high.

In the first case, when there is a lack of iron, gardenias require slightly more iron than other plants. When raising gardenias, you should add a little ferrous sulfate at ordinary times, and ferrous sulfate should be added regularly for gardenias. According to the proportion, it should be added once every three months to meet the normal growth needs of gardenias.

Of course, the potting soil that was changed a little better, it may be enough to add it once in the middle of the year, iron is still very important for gardenias, ferrous sulfate is also a common fertilizer for gardenia fans, but please remember that don't keep adding, too much iron will also cause poisoning.

The second situation is the lack of nitrogen fertilizer, this situation is relatively rare, very long friends will be really lazy, really only watering, do not do other management, and even two or three years do not change the soil, the potting soil in the gardenia has been very compact, nutrients are also absorbed very little, nitrogen fertilizer is the most elements contained in the soil, but it is also the element that plants demand the most. If the leaves turn yellow due to lack of nitrogen fertilizer, you only need to add a quick nitrogen fertilizer quickly, and it can be treated in 3-5 days.

The most critical thing to maintain gardenia is to change the soil and fertilize, which are effective means to prevent gardenia yellow leaves. The soil needed for repotting is made of pine needle soil and garden soil, which must be permeable and breathable, so that the growth will be more vigorous, and the iron element in the pine needle soil is also relatively rich. To fertilize gardenias, you can apply trium water-soluble fertilizer.

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.

Put it in a place with bright light, or in a place where the sun can not be exposed to the sun in the morning and afternoon at noon, not exposed, keep ventilation, but do not blow strong wind, and water less. Maintain 50%-60% moisture in the soil. If you can't control it, you can see that the surface of the potting soil is dry, so you can water it less.

When watering, if you see that the water is quickly absorbed. Just pour less. If the temperature is very high, water it in the morning and evening, or spray some water on the leaves and branches to increase the humidity.

You buy gardenia seedlings, which are cultivated in a greenhouse before you buy them, and after you buy them, you don't adapt to the new environment for the time being. So there will be dry and fallen leaves. It'll be fine after a while.

The soil is not acidic enough--- the leaves are yellow.

It is best to buy the first shade maintenance, the southern flower farmers dig out of the ground, after transportation to the hands of the florist on the pot to sell, the root system is injured, the root system absorption capacity recovery takes time, the old leaves are yellow, this is the instinct of the plant to save its own life.

Don't use fertilizer just yet. Wait for new leaves to grow before applying a thin fertilizer. Watering should not be too frequent, and wait for the surface soil to dry before watering thoroughly.

When watering, add a small amount of vinegar to the water, and the pH is required to be between the pH value to ensure normal growth. Too much acid and alkali is not good for flowers. It is best to go to the pharmacy to buy a pH test strip (2 yuan, which can be used for a long time) to test the acidity of water and vinegar first, and then water the flowers, as a basis for testing.

When choosing potted flowers, it is particularly important to see whether they are new soil or old soil, which usually has moss or grass on the surface. If necessary, nutrient solution or thin liquid fertilizer can be used. If it is new soil, you should help him cut off some branches and leaves, pick off the flower buds, don't rush to watch the flowers, reduce consumption, carefully adjust the root system, foliar spray, don't see strong light, and apply thin fertilizer after recovery to bloom naturally.

Newly bought gardenias, yellow leaves drop buds? Let's see if there is "this thing" in the basin
