Gardenia leaves are not shiny, what causes it?

Gardenia leaves are green and shiny all year round, in the breeding process, it is found that gardenia leaves are not bright enough, in fact, it is often said that green and shiny, so this situation occurs, it is generally in the maintenance process, not according to the needs of gardenia to maintain the cause, as for what is going on, how to maintain, gardenia leaves will be shiny, let me talk about my own point of view.

Light affects the color of gardenia leaves

Put the gardenia in a place with poor light and place it for a long time, then the gardenia is easy to grow, or the leaves are not shiny enough. However, it is not possible to put gardenias in a place with strong sunlight, if the plant is exposed to strong sunlight, the leaves will be yellowish, and it will not be shiny, and in severe cases, it will be sunburned, it will become charred and withered, and it will affect the appreciation value.

Suggestion: When cultivating gardenias, they should usually be placed in a sunny location, such as a balcony or window sill, to maintain sufficient light, and not to be placed in a dark environment for a long time. But to the gardenia sun, as long as spring, autumn, winter, when the sun is not very strong, you can let the sun shine directly, once it is summer, you need to shade the gardenia, otherwise it is easy to be sunburned.

Insufficient nutrients will make the leaves of gardenias not shiny enough

Cultivating gardenias, if there is no fertilization for a long time, then it will cause gardenias to grow poorly, and the leaves will not be shiny. Because the growth of gardenias requires sufficient nutrition, they can grow vigorously, flourish, and the leaves are more green and shiny, and they can maintain normal flowering. If you don't fertilize for a long time, the soil will be too poor and will affect the color of the gardenia leaves.

Suggestion: When cultivating gardenias, you need to fertilize gardenias evenly, do not use raw fertilizer or strong fertilizer, it is easy to cause gardenia to burn roots, there will be rotten roots or leaves scorched, yellowing and other symptoms, serious plants will wither. To fertilize gardenias, you should apply completely decomposed organic fertilizer, and at the same time supplement nitrogen, potassium and phosphorus, which can make gardenias grow vigorously, with lush branches and green leaves.

Summary

Gardenia leaves are not shiny enough, the main reason is these two points, according to the usual maintenance situation to analyze, find out the reason, you can solve it according to the demand, gardenia leaves will remain oily. It should also be noted that the usual watering should also be controlled, not a large amount of watering, resulting in waterlogging, but also make the leaves of gardenia yellow or rotten roots of the plant withered, should be according to the demand, the soil can be watered thoroughly after drying, to maintain the health of the root system.

The main reason is that the root series is damaged, resulting in insufficient supply of nutrients and water. When the root system is damaged, the growth of the roots and leaves of the plant's vegetative organs will stagnate the phenomenon.

This can be due to a lack of chlorophyll, lack of photosynthesis, lack of water, lack of fertilizers, or insufficient mineral content of the soil.

It is very likely that the light is not suitable, it may be that the moisture management is not reasonable enough, the ventilation is not enough, the humidity is not enough, and there is no pruning.

The solution to the fact that the leaves of gardenias are not green.

1. Lack of light.

Although gardenia is a shade-loving plant, it cannot be lost to a little light, and if it is not exposed to light for a long time, it will cause the leaves to become yellow and dry, and it is not as vibrant as green.

Treatment method: Gardenia should be placed in ventilation and semi-shade in summer, and it is best to accept astigmatism, and it is best to put it in a place where the sun and the temperature is not lower than 0 in winter.

2. Improper moisture.

If the gardenia is overwatered during the planting process, the young leaves will be dull and dull, and the old leaves will not be affected, but the leaves will be yellow-green, and even new leaves will not grow.

Treatment: Put the gardenia off the pot in a ventilated and cool place and put it 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.

3. Improper fertilization.

Gardenia in the growth period if improper fertilization will also appear a variety of problems, 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 hypertrophic and dull.

Treatment method: If the leaves are not green, it is generally a lack of nitrogen fertilizer, nitrogen fertilizer promotes leaf green, phosphate fertilizer promotes root growth, when the plant is deficient in potassium, the old leaves turn from green to brown, and at this time it is necessary to apply appropriate Bika potassium fertilizer is the most effective.

4. Air drying.

As a southern flower, gardenia likes a warm and humid climate, and if the air humidity is too low during the budding, the leaves will not be shiny and not green.

Treatment: What to do if the leaves of gardenia are not green, the gardenia needs to grow in a higher humidity environment during the maintenance process, and the leaves can can be adjusted into a mist and sprayed frequently. p Subheading E

5. Spider disease.

There is also a possibility that the green leaves of gardenia are caused by red spider disease, and if there are small insects on the back of the leaves of gardenias, red spiders will grow if they are not well ventilated.

Solution: It's very simple, move to the toilet, block some potting soil with a plastic bag, and take a shower, once or twice.

The new leaves grow slowly, yellow, and feel qualitative, maybe the virus is sick, or there is a lack of nutrients, try this.

The newly grown leaves of gardenias are not very green, mainly due to the lack of corresponding fertilizer, once the west lacks fertilizer, then the leaves will not be very green.

The leaves are tender yellow as soon as they come out.

Gardenias are a popular flower because their white flowers give people the feeling of first love, and they also give off a fresh fragrance that makes people feel particularly good. It also blooms for a long time, from May to November, and the most beautiful flowers are blooming one after another. But if you want to raise it well, you must work the maintenance method, like the following four wrong maintenance methods, you must not have, otherwise the plant will die in minutes.

1. The soil becomes a large lump.

Gardenias are suitable for growing in soft, breathable, acidic soil, so if the soil becomes a large lump, it can damage the root system of the plant. Water and nutrients cannot be absorbed in time, so the plant will become more and more unenergetic, and any yellow leaves and rotten roots will come to the door, and naturally they will not be able to bloom. Therefore, it is important to ensure that the soil is soft and must not be ignored.

2. Too much or too much watering.

Gardenias' need for water is still quite high, especially when the growth of Hu Collapse is the most vigorous, it must be watered in time. Generally, it can be watered when the soil surface is dry, and it must be kept moist in order to maintain its normal growth. However, you can't water too much, and you still need a certain amount of dry and wet alternation to make the root system grow better.

Otherwise, if it is buried in a damp place for a long time, there will definitely be rotten pants, which will affect the absorption capacity of the root system, so the plant will not grow large, and the branches and leaves will turn yellow and dry.

3. The ventilation is too poor.

Gardenias are in a warm and humid environment for a long time, so they must have good ventilation, otherwise they will definitely get sick if they are stuffy all the time. And it will also affect its own growth, when the time comes, not only the leaves will become lighter and lighter, but even insect diseases will come to the door one after another.

4. Lack of fertility.

Gardenia needs sufficient nutrients for growth, if you don't change pots and don't fertilize for many years, the nutrients in the soil have long been exhausted, what to grow, what to use to bloom? It's not at all. Therefore, the lack of fertilizer will also make the gardenia grow poorly, and the leaves will not grow big or green, let alone flower.

In fact, it is not very difficult to raise a spine gardenia, as long as you put it on the windowsill, add more light, ventilate it more, and then water it more but don't accumulate water. As long as it is kept in the most comfortable environment, the plant will grow very vigorously and will continue to bloom.

<> causes: Generally caused by poor ventilation or overwatering. This situation will improve when environmental problems and conservation methods are improved.

Solution: Move the plants to a well-ventilated place, reduce watering at the same time, and water thoroughly after the soil is dry.

Reason: Ferrous sulfate is used too much, resulting in high acidity of the potting soil. This in turn affects the growth of gardenias, resulting in blackening of leaf tips.

Solution: If there are not many black leaves, rinse the potting soil with water. If there are many black leaves, then you should change the pot and soil in time, and check the roots for burns. At the same time, reduce the number of spraying of ferrous sulfate, generally once every one to two months.

Reason: Gardenias prefer acidic soils, which can also cause blackening of leaves if the soil alkali content is high.

Solution: Add a certain ferrous sulfate solution to the potting soil. It can be sprayed on the leaf surface after mixing with water, once a month, too often will also be detrimental to growth.

Reason: Root-knot nematodes are one of the common pests of gardenias, and because they are mostly in the roots, they can be difficult to find.

Solution: Check whether there is a nodule in the root**, if so, cut it off, and use pesticides to exterminate insects.

The black and dry leaf tips of gardenia may be related to the soil and pests, during the maintenance period, the soil is too acidic or alkalized and agglomerate, and the root system cannot grow normally, which will make the leaf tips of gardenia appear black or dry. During the growth period, if the environment is not proper or the maintenance is improper, the leaf tips of gardenias will also turn black, dry out or wilt after being attacked by insects.

During the growth period of gardenias, the leaf tips are black and dry, which may be caused by the high acidity of the soil. Gardenias prefer acidic soils, but excessive use of ferrous sulphate solutions during the growing period will increase the acidity of the soil. If the soil is too acidic, the root system of the gardenia cannot absorb and grow normally, which will make the leaf tips of the gardenia black or dry.

Gardenias prefer acidic soils, and during the growing period, the leaf tips of gardenias gradually turn black and dry out after the soil is alkalized. Long-term failure to change the soil will lead to soil alkalinization and compaction, which will make the root system of gardenia unable to breathe normally, resulting in poor growth of gardenias. During the maintenance period, the potting soil should be changed regularly to allow the gardenia to grow normally.

During the growth period of gardenias, the leaf tips will appear black or dry after being attacked by insects. During the maintenance period, gardenias are exposed to unsuitable conditions, and their growth deteriorates and they will be attacked by root-knot nematodes. After being attacked by insects, the leaves of gardenias will turn black or dry up, and the leaves need to be cut off and then sprayed with pesticides to remove insects.

During the maintenance period, gardenias need to be managed and given sufficient light, water and fertilizer to enable them to grow normally. During the curing period, it is necessary to water and fertilize the appropriate amount of watering and fertilization, and to keep the soil moist to ensure that the nutrients are sufficient. Spraying gardenias regularly to prevent pests and diseases can make gardenias grow better in the later stage.

What causes the tips of gardenia leaves to be black and dry? Nowadays, many people like flowers, and gardenias are also liked by many flower lovers, so do you know what is the reason why the tips of gardenia leaves are black and dry? Below I have compiled some of the content related to it for you, let's take a look!

Why are the tips of gardenia leaves black and dry

1. Soil alkalization

Gardenia is suitable for growing in acidic soil, if the planting soil is alkalized, it will cause the leaf tip of the plant to be black and dry, at this time you can replace the fertile and loose acidic soil for the gardenia, replant, you can also water the soil to soak the water of the orange peel, adjust the acidity and alkalinity of the soil less than seven.

2. Improper fertilization

Gardenia in the process of growth of nutrients demand is larger, in the process of maintenance, the nutrients provided for the plant are unbalanced, it will lead to the lack of potassium and iron in the tip of the gardenia leaf and black and dry, so in the later maintenance, it can be provided with mixed fertilizer rich in nitrogen, phosphorus and potassium elements, so that the plant can absorb balanced nutrients.

3. Insufficient light

Gardenia is suitable for growing in a sunny environment, in the process of maintenance, if the light provided for it is insufficient, or there are large light-blocking plants in the planting area, it will cause the leaf tips of the plant to be black and dry, so in the later maintenance, it is necessary to place the gardenia in a sunny environment, so that the plant receives all-day sunlight.

4. Overwatering

Gardenia has a certain demand for water in the process of growth, but frequent water supply to it will lead to water rot at the root of the plant, and the leaf tip will be black and dry, at this time, it is necessary to loosen the soil in time, drain the excess water in the soil, and water carbendazim solution to the soil to help the gardenia return to normal growth.

How to breed gardenias

1. Suitable temperature

Gardenias are not cold-tolerant, and when cultivating gardenias in winter, if the ambient temperature is below 0 degrees, it will cause the plants to be frostbitten, which will make the gardenia leaves yellow and wilted, and it is necessary to move the gardenia to a warm one in mid-October every year'Maintain them indoors and wait until late April to remove the gardenias from the room.

2. Soil conditions

Gardenia is suitable for growing in loose, breathable and acidic soil, when cultivating gardenias, if the soil is not replaced for a long time, it will cause the soil to become hardened and stiff, so that the gardenia flowers fall, need to replace the soil every 3-4 years, you can use loose and fertile humus with good drainage.

3. Apply fertilizer

During the gardenia seedling period, it is necessary to provide it with bean cake or farmhouse fertilizer after decay, so that the growth rate of gardenia is accelerated, and during the flowering period of gardenia, it is necessary to apply compound fertilizer based on phosphorus and potassium to increase the number of flowers, and in the flowering period of gardenia, it is necessary to spray potassium dihydrogen phosphate to it.

4. Maintenance management

When maintaining gardenias, you need to prune the branches and leaves of the plant regularly, you can cut off the residual flowers of the plant to make the gardenia more beautiful, and you also need to spray water around the gardenia when the weather is too hot to maintain the humidity of the plant, and you also need to let the gardenia receive no less than five hours of light every day.
