Why do gardenias lose their leaves Poor ventilation can lead to leaf loss

Yellowing of leaves is one of the common diseases of gardenias, and many elements can cause gardenias to turn yellow or even lose their leaves.

1. Although gardenia is a flower that likes a moist environment, if it is watered too much, the potting soil will be too much water, which will lead to a decrease in the air in the soil and damage to the root system, which can make the leaves yellow and lose their leaves. Therefore, special care should be taken during the maintenance process. In addition, gardenia is a positive flower, temporarily placed indoors is acceptable, a long time without sunlight, can not carry out photosynthetic function, the leaves will turn yellow.

Therefore, in spring, gardenias must be maintained outdoors in full sunlight as much as possible.

2. Flowers with flower bones are the most vigorous physiological activities, not only to meet the needs of physiological reproduction, but also to meet the needs of reproductive reproduction, which must transport a large number of nutrients through the root system to provide leaves and flowers to develop the needs, at this time, if you suddenly change the environment of the maintenance site, or change the pot and start the soil, the physiological balance will be broken, the leaves and flower buds can not quickly adapt to the new environment or get the nutrients they deserve, there will be leaf drop, bud drop, and even death.

3. Gardenias also need iron to moisturize, and iron deficiency will cause yellowing. Some leaves under the roots are a little yellow, not yellowing, yellowing disease first appears on the new leaves, beginning to be pale yellow or yellowish-white, the leaf veins are still green, slowly the leaves atrophy, and even fall off and die. Therefore, gardenia must use well-ventilated, well-ventilated acidic soil, and should also be sprayed with ferrous sulfate aqueous solution frequently in maintenance to prevent yellowing.

4. Magnesium deficiency can also cause yellowing of leaves, characterized by the yellowing of old leaves and the gradual development of new leaves, the leaf veins are still green, and the leaves fall off and die when they are severe. In this case, boron and magnesium fertilizer can be sprayed to prevent and control.

5. Too much sunlight will also cause the leaves to turn yellow or even fall off. Gardenia likes semi-shade, afraid of strong light exposure, requires about 50% shade, and can only be directly exposed to sunlight in the morning and evening in summer.

Improper handling of this "factor" can lead to the appearance of dry leaf edges in gardenias.

Of course, old leaves and excess branches can be pruned.

Gardenia leaves wilt, 2 reasons to solve in time, stall troubles.

1. Although gardenia is a flower that likes a humid environment, if it is watered too much, the potting soil will be too much water, which will lead to a decrease in the air in the soil and injury to the root system, which can make the leaves yellow and lose their leaves;

2. Flowers with flower bones are the most vigorous physiological activities, not only to meet the needs of physiological reproduction, but also to meet the needs of reproductive reproduction, which must transport a large number of nutrients through the root system to provide leaves and flowers to develop the needs, at this time, if you suddenly change the environment of the conservation site, or change the pot to start the soil search, the physiological balance will be broken, the leaves and buds can not quickly adapt to the new environment or get the nutrients they deserve, and the jujube will fall leaves, buds, and even die;

3. Gardenia also needs iron to moisturize, and iron deficiency will cause yellowing.

The leaves of the gardenia are wilting, and the two reasons for the lack of liquid are solved in time, and the stall is troubled.

Soil discomfort: Gardenia yellow leaves may be caused by too heavy or alkaline soil, the soil should be changed as soon as possible, and the ferrous sulfate solution should be watered regularly during the maintenance period.

Discomfort of light: Long-term exposure to the sun or placed in the shade is easy to yellow leaves, and more astigmatism should be done.

Lack of water: Gardenia yellow leaves may also be a lack of water and not drought tolerant, so they should be hydrated in time.

The temperature is too low: it is cold-resistant, if the temperature is not well controlled in winter, it will be frozen, resulting in yellow leaves, which should be kept warm.

First, the soil is lacking and uncomfortable.

Gardenias have certain requirements for the soil during the growth period, like soft, breathable, fertile and slightly acidic soil, afraid of heavy clay soil and alkaline soil, if the soil is not suitable will cause the leaves to turn yellow, and even affect flowering. If it is caused by soil problems, it is necessary to change the soil as soon as possible, and the cultivation in the northern region should also be regularly watered with ferrous sulfate solution or vinegar solution, which can maintain the acidity of the soil, avoid too much alkalinity, and promote the growth of young leaves.

Second, the light is uncomfortable.

Gardenias have a certain shade tolerance and are not sun tolerant. Prolonged exposure to shade or exposure to the sun during the growing period will cause the leaves to turn yellow. If it is caused by lack of light, it should be moved to a well-lit environment as soon as possible, and more light should be exposed to astigmatism to promote better photosynthesis.

If it is sunburned by long-term exposure to the sun, it should be shaded, especially the strong light in summer, which must be blocked in time.

3. Lack of moisture.

Gardenias prefer moist environments and are not drought tolerant. If there is no watering for a long time during the breeding period, there is no rainfall, the soil is dry, and the climate is dry, which will easily cause the leaves of gardenia to turn yellow, which will seriously affect the growth of gardenias. If this is the case, it should be watered as soon as possible, preferably thoroughly, so that the root system at the bottom can also absorb the water.

In a dry climate, it is necessary to spray water frequently to ensure a certain humidity, so that gardenias can resume growth as soon as possible and grow more vigorously.

Fourth, the temperature is too low.

Gardenias like a warm environment, and can only germinate and grow in a warm environment, and their cold tolerance is very poor. If the temperature cannot be well controlled in winter, and the temperature is below 5 for a long time, gardenias in such an environment will be susceptible to freezing, will be frostbitten, and are prone to yellowing of leaves. If this situation is caused, it is necessary to take warm measures as soon as possible, the temperature should be stabilized at about 10, and the minimum should be kept warm at a late grip of more than 5, so that the gardenia can be restored as soon as possible and can also ensure safe wintering.
