What happened to the barking of the trunk of the gardenia tree? What to do if the leaves of gardenia

Gardenias. The bark of the trunk is due to gardenia rot disease.

Gardenia rot disease.

Symptom. Gardenia rot disease mainly harms the main stem of gardenia, and the stem is hypertrophied and cracked under the main trunk of the plant at the time of disease, and the main stem gradually shrinks and rots.

Gardenia. Prevention and control methods.

Prune in time after flowering to remove the wilted branches. And thinning is carried out to reduce nutrient consumption and promote the growth of the main trunk.

If the stalk is found to be rotten, scrape off the rotten part in time and apply 5 10 degrees stone sulfur mixture.

Several times. Here's a look at other conditions, and how to fix them.

Gardenia soot disease.

Symptom. Soot disease mainly occurs between branches and leaves, and when the disease occurs, brownish-white lesions will appear on the branches and leaves, the branches will stop growing, and the plants will gradually wilt.

Gardenia. Prevention and control methods.

When the disease occurs, scrub with water in time to erase the white fungus on the branches and leaves. Or spray 1000 1200 times carbendazim.

and Baumé stone sulfur mixture for comprehensive control.

Gardenia yellowing.

Symptom. Gardenia yellowing is a physiological disease that damages the leaves of gardenias. At the onset of the disease, the leaves gradually turn yellow, the growth of the plant slows down, and gradually wilts.

Gardenia. Prevention and control methods.

The plants are found to be yellow, ferrous sulfate is available.

The solution is sprayed on the foliage or the roots are watered, and the concentration can be adjusted higher when watering the roots. The spraying time is chosen in the morning after the dew has dried, and after watering (spraying) in the sun. If the yellowing of the plant is severe, it can be sprayed once a week, but the spraying concentration should be controlled to avoid burning the roots.

After a period of time, the leaves of the plant will gradually turn green and return to normal.

In order to avoid yellowing of the plants, a solution of 4 5 ferrous sulfate can be sprayed prophylactically during the growth of gardenias in April and August every year.

When it comes to gardenias, the first word in my mind is "white", the most attractive thing about gardenias is its open petals, the white petals are very beautiful, gardenias are more suitable for female friends to raise, can show a person's character, and the faint fragrance of gardenia is also intoxicating.

There are not a few flower friends who raise gardenias around them, and they will share some of the ** after opening with each other every year, I personally like gardenias, I can usually enjoy the leaves, you can enjoy the flowers during the flowering period, the leaves of gardenias are dark green, and they are also very good to watch.

If you want to make gardenias bloom beautiful flowers, you need to pay attention to soil, fertilization, and watering, and you should use at least 3 kinds of fertilizers before and after gardenias in spring, and if you use the right fertilizer, the number of flowers can be more, and the color of the leaves will be more dark green.

Gardenia loess must not be used, acidic humus soil planting gardenia is the best, you can also use your own with rotten leaves and bark, plus rotten vegetable leaves, fruit skin, soil plus fruit skin to increase the acidity of the soil, gardenia will not easily appear yellow leaves.

Gardenia can burst out, the key is in the use of fertilizer, in April every year, in the soil of gardenia can be appropriately added to the rotten chicken manure, chicken manure is a good organic fertilizer, can be long-term gardenia ** nutrients, secondly, you can usually use potassium dihydrogen phosphate granular fertilizer, once a month, has continued to bloom in July.

Potassium dihydrogen phosphate granular fertilizer plus well-rotted organic fertilizer, these two fertilizers plus diluted liquid fertilizer for spraying leaves, 3 kinds of fertilizers are well matched, do not worry about gardenia not flowering, diluted liquid fertilizer sprinkler leaf irrigation effect is still very good, half a month can be sprayed once, gardenia leaves will have obvious changes.

The looser the flower soil for planting gardenias, the better, the soft flower soil has good air permeability, good fertilizer retention effect, the water is soaked evenly in the soil, and the roots in the soil can absorb water, which is convenient for the transportation of water in the branches, and will not appear yellow leaves because of the dry air.

Watering gardenias can not use tap water, must be softened water can be directly watered, tap water at home is hard water, contains a lot of chlorine, calcium and magnesium elements, watering in the soil for a long time will make the flower soil stiff, tap water first take out, dry for a few days, and then take it to water.

Gardenia has a very serious problem, it likes yellow leaves, the situation of yellow leaves is very serious, the yellow leaves are easily pulled off, with ferrous sulfate in accordance with the ratio of 1:2000 to water, timely irrigation of roots, ferrous sulfate can acidify the flower soil, after soil acidification, the phenomenon of yellow leaves can play a certain role in alleviating.

The floral fragrance of gardenia is very strong, very suitable for indoor cultivation, blooming gardenia is full of floral fragrance throughout the room, giving people a very comfortable feeling, spring and summer flowers can not be missed flower varieties.

Gardenias often have this problem, the leaves dry out, the buds turn black, what the hell is wrong?

Summary. Cut back on watering and wait until the soil is dry;

Proper exposure and cultivation, it is best to expose gardenias in spring and autumn, carry out scattered light, and try to avoid direct strong light;

Soil fertilization should be reasonable, gardenia likes acidic soil, can be watered with ferrous sulfate, two or three times a year, or pine needle soil, humus soil, and in the spring growth period once or twice a month to apply organic fertilizer water.

What to do if the leaves of gardenia dries out!

Cut back on watering and wait until the soil is dry; 2.Proper exposure and cultivation, it is best to expose gardenias in spring and autumn, carry out scattered light, and try to avoid direct strong light; 3.With the rest of the vertical or soil fertilization to the erection of Wu Li Fiber Ant, gardenia likes acidic soil, can be watered with a little ferrous sulfate, two or three times a year, or pine needle soil, humus soil, and in the spring growth period once or twice a month to apply organic fertilizer water.

I bought this pot of flowers newly, and the leaves dried up in the second day, can it still be saved?

Just because the leaves are dry doesn't mean the flowers are dead, so take a look at them for a few days.

Causes and solutions for gardenia leaves to dry out.

1. The pH value in the soil is too high.

The dry leaves of gardenias are mainly caused by an excessively high pH in the soil, and it is recommended to cultivate them with humus-rich loam soil. It is best to add an appropriate amount of vinegar after watering water to make it slightly acidic, and the specific pH value can be measured with pH test paper, which is sold in chemical and pharmaceutical equipment stores. You can also buy a little ferrous sulfate, soak it in water, and water it every 10 days.

2. Lack of water and light.

Generally, it is caused by lack of water and light, because gardenias are yellow mud mounds in the place of origin, and when they go to the flower market to sell goods, they will change pots and fill in new soil, so that it is easy to see the dry and wet situation of Huang Nituo, because the new soil is generally very loose and easy to absorb water, but as long as Huang Nituo is dry, it is not easy to water through. This can easily lead to dehydration, and the leaves are prone to drying out. So I suggest that you soak the pot in a bucket for a day and a night, so that you can soak the yellow mud through and water it more frequently in the future.

Gardenia needs to prune off the residual flowers and dead leaves after flowering, which can reduce the loss of nutrients, and fertilizer should be supplemented in time after flowering, fertilizer containing phosphorus and potassium can be applied, pay attention to thin fertilizer frequently, do not use thick fertilizer, gardenia likes a moist environment, need to be watered regularly during the growth period, and can be watered after flowering, the main soil can be watered when it is dry, and if it is moist, it is necessary to control the amount of watering.

When do gardenias bloom.

Gardenia, also known as gardenia, yellow gardenia, is a plant of the gentian Rubiaceae family, its flower color is white, meaning beautiful love and hope, fresh and elegant appearance, is strong and perseverance of persistence, its fragrant floral fragrance, to bring people that vitality.

Gardenias can be propagated by dividing and sowing, the best planting time is in spring, the temperature at this time is suitable for seed germination, the flowering period is generally around 5-8 months, and the general flowering time can last for about a month.

Gardenia post-flowering treatment method.

Gardenias need to be pruned off the residual flowers and dead leaves after flowering, which can reduce the loss of nutrients, and also supplement thin fertilizer in time to meet the nutrient needs of the plants, and also need to maintain the slight moisture of the soil, pay attention not to overwater.

1. Prune

Gardenia needs to be cut off after flowering, this is a very important work, the flowering period consumes a lot of nutrients, if the residual flowers, yellow leaves are left on the branches, it is bound to consume more nutrients, resulting in poor plant growth, not conducive to recovery.

2. Watering

Gardenias like a moist environment, need to be watered regularly during the growth period, to maintain the moist state of the soil, flowering can also be watered, the main soil can be watered when dry, if the soil is still wet, you can reduce the number of watering.

3. Fertilization

Gardenia after flowering to timely fertilizer, can be applied to the first beam containing phosphorus and potassium fertilizer, pay attention to the frequent application of thin fertilizer, can not use thick fertilizer, the root of the fertilizer damage, will affect the growth of the plant.

How to raise gardenias and bloom more.

Gardenia is suitable for soil culture, suitable for planting in breathable, well-drained soil, if it is prepared by itself, can not use heavy soil, in order to make it better flowering, it needs to be maintained in a place where the sun is more full of energy, but there is no visible strong light, and you need to do a good job of shading in summer, in addition, you also need to loosen the soil in time, change pots, and provide sufficient water and nutrients.

Causes of gardenia leaf dryness and solutions to the disorder:

1. Dry and die: as an evergreen plant, positive.

Under normal circumstances, gardenias do not have many dead leaves, if all the leaves dry up and fall off, and the branches become brittle, it means that it is dead and there is no cure.

2. Watering too much: At this time, you should reduce watering, place gardenia potted plants in a sunny place, cut off the dry leaves, and new leaves will grow after a while. Therefore, it is important to pay attention to controlling the amount of watering at ordinary times, and then watering when it is dry.

Pictured: Gardenia leaves are dry and on the verge of death.

3. Lack of fertilizer: nitrogen deficiency will make the leaves yellow, and the new leaves are small and brittle; The old leaves of potassium deficiency turned from green to brown; The old phosphorus-deficient leaves are purplish-red or dark red. For the above cases, well-rotted human feces or cake fertilizer can be applied thinly.

Yellowing caused by iron deficiency: This yellowing disease, manifested in new leaves, is pale yellow or white at the beginning, the leaf veins are still green, and the leaf veins are also yellow or white in severe cases, and eventually the leaves will dry up and die. In this case, the aqueous solution of ferrous sulfate that can be sprayed can be prevented.

Yellowing caused by magnesium deficiency: This yellowing disease 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. In this case, a 0·8% boron and magnesium fertilizer can be sprayed to prevent and control.

Pictured: Gardenia leaves turn yellow and fall.

4. Summer exposure: exposure to the sun will also cause gardenia leaves to dry up, if it is a potted plant, pay attention to prevent sun exposure, you can move to a cooler, morning and evening sunshine place.

Tips】Gardenia is prone to scale insect damage and is accompanied by soot disease in winter when the indoor ventilation is poor and the temperature and humidity are too high. For scale insects, bamboo skewers can be used to scrape off, and No. 20 petroleum emulsion can also be sprayed with 200 times water. For soot disease, it can be scrubbed with water, or sprayed with carbendazim 1000 times for prevention and control.

The reasons and methods for gardenia leaves to dry out are as follows:

1. When iron is deficient, the veins of young leaves lose green and yellow, which will make the whole rock excitation leaves yellow, and even scorched leaves and branches wilt, and finally cause the death of the plant. In this case, the ferrous sulfate aqueous solution that can be sprayed can be used for rough sock prevention.

2. The yellowing disease caused by magnesium deficiency begins to develop from the old leaves to the new leaves, and the leaf veins are still green, and the leaves fall off and die in severe cases. In this case, boron and magnesium fertilizer can be sprayed to prevent and control. Excessive watering, filial piety, etc., will also cause the phenomenon of yellow leaves, so special attention should be paid in the maintenance process.

3. For lack of water, it is best to choose well-drained, loose and fertile acidic soil for gardenias; Potted plants should use 2 parts of humus and 1 part of garden soil, and it is better if you add some mountain mud to mix.

1. Cultivating the soil to improve the soil.

In the case of dry leaves, it may be that the maintenance time is longer, so that the pH value in the potting soil becomes larger, and it is difficult to adapt to the alkaline plum soil, so there is a problem with the plant. When watering, you can add vinegar to make the potting soil acidic, or you can buy ferrous sulfate and soak it in water and water it once every other time to improve the acidity and alkalinity.

2. Normal sunlight.

Sunlight is a very important point in growth, and it needs to be provided normally, and too much sunlight or lack of light will affect it. You can cut off the dry leaves, and then supplement the sun normally, pay attention to shade in summer, and do not contact strong light.

3. Control the temperature.

The plant cannot withstand the low temperature environment during growth, and is subject to light frost damage, and the leaves of the plant will also turn yellow. The temperature can be controlled within a suitable range and moved indoors in time in winter.

Fourth, adjust the watering.

The application of water is also very important, if there is too much water, it will cause water to accumulate in the orange soil of the pot, and the root system will rot and it will be difficult to transport water and fertilizer. If it is not watered for a long time, there is no water supply inside. In this case, it is necessary to find the cause and adjust the moisture according to the situation.

5. Prevention and control of pests and diseases.

There is no ventilation for a long time, and the stuffy indoor heat leads to infection with pests and diseases. If the quantity is too small, it can be killed manually, and if the quantity is too large, it can be sprayed.
