The method of high pressure propagation of Gardenia jasminoides should be peeled.

Gardenia, this is what many people have seen, this gardenia is super likeable, gardenia high-pressure reproduction method is how:

1. Peel the branches in a ring

Choose a sharp knife, to pre-select disinfection before use, the cut part is 1 cm below the growth node, ring peeling part of about 3 cm.

The peeled part of gardenia should be scraped clean and be careful not to hurt the inner stem.

2. Wrapping water moss

You can see here that it is more appropriate to use water moss for the soil mass that has been wrapped up (even for water-retaining loose soil). After completely soaking in clean water, it can be used and tied up with a transparent plastic film, so that you can see whether it has taken root or not. after that, bind both sides with a rope to prevent moisture loss.

3. Cut branches

After about 30-45 days, you can see that the roots grow inside the plastic film, and at this time, you can cut off the stem together with the soil ball, and cut it from 2 to 3 centimeters at the bottom of the soil ball.

As shown in the above picture, with soil ball transplanting, gardenia is easy to survive, the root system grows better, do not want to cut branches, even if rooted, the survival rate of transplanting is still very low.

About the gardenia high-pressure method propagation method is introduced here, this gardenia high-pressure method can let you raise a lot of gardenia.

Pot culture methods and matters needing attention of gardenia

Gardenia beautiful appearance, very attractive, give off a fresh smell, with a good ornamental value, cultured gardenia green leaves, white as jade, do you know what are the breeding methods and matters needing attention of gardenia? What are the reasons why mast flowers do not blossom? Let's take a look at it together.

Propagation methods of Gardenia jasminoides

1. Cuttage propagation: from May to June, select semi-lignified, fully developed twigs, cut into 10mur15cm long, soak the base with 1000 mg / kg naphthalene caproic acid for 3 seconds, cuttage in acidic soil with strong water and fertility conservation, generally use 3 parts of rotten leaf soil or mountain mud, 1 part of sawdust, peat or river sand, take root about 1 month after planting, and transplant after 50 days. The method of water insertion is often used in summer in the south, which is carried out from April to July. The cut cuttings, which are 15 centimeters long and with 2 or 3 leaves on the top, are inserted on the basket lid or perforated plastic board, and the lid or plastic plate is floated on the surface. The upper part of the insert can be exposed to the water. Put it in the semi-shade after insertion and keep the water temperature for 16-18 ℃. New roots can grow in 20 days. When the temperature is high, change the water frequently, change the water once a day, can not make the water deteriorate. When the root is 2-3 cm long, it can be transplanted.

2. Striping propagation: most of them are carried out in May to June. Select 1-year-old, 2-year-old strong branches, 25 cm long, pressed into the soil 3 cm 5 cm, about 1 month can take root, 2 months later can be cut off from the mother. Can also be high pressure, that is, on the adult gardenia, choose 2-3-year-old strong branches ring peeling 1cm, and then wrapped in moist peat, the outside wrapped with plastic bags to keep the soil moist, about 40 days can grow new roots, 2-3 months later cut off the mother.

3. Ramet propagation: in May, there are 2 or 3 branches growing at the base of the root, which can be cut from the root with a knife, and each ramet has fine roots. After the wound is coated with plant ash, it will be planted separately.

Culture method of Gardenia jasminoides

1. Potted soil selection: gardenia is an indicator flower in acidic soil, and the suitable pH value is 5 to 6. Therefore, the slightly acidic environment of the soil is the key to determine the growth of gardenia. If the soil acidity is not suitable, it will get twice the result with half the effort in the future management. The culture soil is made of 70% of slightly acidic sandy red soil and 30% of rotten leaves. It is appropriate to control the soil pH value between 4.0 and 6.5. Cultivation soil can choose rotten leaf soil, peat soil or retting sawdust plus half of the garden soil, avoid using old wall soil and cinder, with the market-sold gentleman orchid soil is more convenient and practical.

2. Scientific watering: gardenia likes moist soil and greater air humidity. Keep the basin soil moist during the growth period from April to September. Watering should be increased appropriately during the growing period. Usually the pot soil can be watered once the soil turns white and thoroughly at one time. Hot and dry in summer, spray to the leaves 2-3 times a day to increase air humidity and help plant cool. However, after the flower budding, watering should not be too much, so as not to cause bud drop. It is better to water dry in winter to prevent the roots from rotting. The surface of the basin soil is watered when it is dry, and a spray can be used to pour water on the leaf surface at night. If it is dry and wilted, it will be bad for growth. If the growth is too prosperous and the internodes are longer, they will not be watered in the evening and will be watered again when the sun comes out in the morning. In the area of alkaline water in the north, tap water should be kept for two days before use. Every three or five days, add 0.5 grams of citric acid and 1 gram of ferrous sulfate to water once per liter to make the leaves oily and green.

3. Rational fertilization: demand for fertilizer for gardenia: gardenia is a fertilizer-loving plant, and 3% rotten cake fertilizer can be added to the culture soil as base fertilizer. In the growing season, the alum fertilizer made by cake fertilizer and ferrous sulfate retting is watered once a week, or 0.1% humic acid total nutrient organic liquid fertilizer can be used. Watering 0.1% potassium dihydrogen phosphate aqueous solution once or twice in the bud stage can make the flowers fat and fragrant. Fertilizer is stopped when the temperature is above 35 ℃ in hot summer and below 15 ℃ in autumn. After entering the peak growing season in April, you can top fertilize every half month (you'd better mix more water when fertilizing to prevent burning flowers). This can not only meet the fertilizer demand of Gardenia jasminoides, but also keep the soil environment in a relatively balanced slightly acidic environment, prevent the occurrence of chlorosis, and avoid the damage of sudden supplement of ferrous sulfate and local excessive acid to gardenia.

4. Bask in the sun more: gardenia likes light and can grow in semi-shade for a long time, but the flower branches are longer and the flowers are less. In addition to the strong light from July to August noon need shade and winter dormancy period, generally need to be maintained in the sun in order to blossom and flourish.

5. Good dormancy in winter: gardenia can survive the winter in open field in Qinling Mountains of China, but the root system of potted gardenia will be damaged after severe winter and recover slowly in spring. In the indoor with heating, although it is not damaged by freezing, the light is insufficient and the growth is thin. Most of the young buds formed in autumn fall off and blossom late in the second year. The better way is to put the potted flowers in a cold room of about 5 ℃ to make them dormant, or wrap the flowerpots with foam and other thermal insulation materials to protect the roots, and put them in the leeward and sunny place to overwinter, which can recover quickly in spring and bloom early.

6. change the pot soil at the right time: the seedlings use small pots and gradually change into large pots. When the crown width is 2 to 3 times the caliber of the basin, it is time to change the basin. The growing season can be changed at any time. After pouring the basin, even the soil block is planted into the new basin, the caliber is about 5 centimeters larger than the original basin. Family potted plants when the pot reaches about 28 cm, generally no longer change the pot but only change the pot soil. It is better to change soil in March in spring. After pouring the basin, cut off part of the old roots, shake off half of the old soil, plant the new soil into the basin and pour water into the pot, put it in a warm semi-shady place, and keep it in the sun when new buds sprout.

7, appropriate pruning: gardenia jasminoides seedlings in the trunk 20 cm high to hit the top, leaving 3 to 4 branches, branches 2 pairs of leaves and then hit the top, promote branches, and then allow its growth. Lobular gardenia does not need to be topped. Trim lightly after flowering every year, cut off the inner chamber branches, diseased and weak branches, and some only grow short branches. When the crown width of Gardenia jasminoides is too large after 4 to 5 years, it can be strongly pruned after flowering, generally leaving 2 pairs of leaves in the upper part of the branch. After budding, the inward growing buds and the lower buds of the trunk will be erased, and the plant shape will become more compact and beautiful. Remember that gardenia can not be cut short in spring, otherwise it will not blossom in that year.

Matters needing attention in Gardenia Culture

1. Gardenia likes to be fat, but is afraid of thick fertilizer. Generally, the cake fertilizer containing more phosphorus and potassium is applied twice before budding, and the fertilization is stopped after budding. If too much fertilizer is applied, it is easy to burn roots and cause budding. During the growing period, rotten cake fertilizer water or manure fertilizer water was applied once every half a month, and 1%-2% ferrous sulfate was added to prevent soil alkalization.

2. Gardenia likes semi-shade and is afraid of strong light, so it requires a shade degree of about 50%. If exposed to the sun, the leaves turn yellow and whiten until they fall off, so they should be kept in a shady place or a place with scattered light in summer. Make it see light in the morning and evening to prevent the leaves from yellowing.

What is the flower language of gardenia?

Gardenia flower language is "eternal love, life waiting and joy" legendary gardenia flower language is waiting for love gardenia flower language: joy. If you like this flower, you have the heart to be grateful and treat others sincerely. As long as others are a little kind to you, you will thank you with your heart. This is because you have a pure heart, do not understand the evil of the human heart, and your sincerity makes you happy, and forgiving others also fills you with joy.

In which month does gardenia blossom?

Gardenia blossoms in a few months and can be divided into the following categories according to the region. North China generally buds in early May and blossoms in the first and middle of June. The flowering period of a flower is 8-5 days, and the whole flowering period is about one month.

What are the reasons for the yellowing of mast flower leaves?

1. Improper moisture

① overwatering: in this case, the tender leaves of the mast flowers are dark yellow and dull, but the old leaves have no obvious change, so just take the flowers out of the pot and place them in a cool, ventilated place and put them back after the soil dries.

② is short of water: the tip or edge of the leaf is withered and dry, and the old leaf is withered and yellow from bottom to top, but the growth of the new leaf is relatively normal, so it should be fully watered and watered thoroughly.

2. Improper lighting

① light is too strong: the sunny part of the leaves have maculae, which only need to be moved to the shade for maintenance, and the new leaves will no longer have maculae.

② lack of sunlight: at this time, the leaves will turn yellow or even fall off, as long as you put them in the sun to replenish the sun.

3. Improper fertilization

① fertilized too much: the new leaf tip appeared brown, the leaf surface was thick and dull, and the old leaf was scorched and shedding. At this time, it is necessary to stop fertilization immediately, and in serious cases, the soil should be washed to reduce the concentration.

Insufficient ② fertilizer: insufficient fertilizer can also cause plant yellowing, such as iron deficiency, leaves are light yellow or white, and leaf veins are still green, so it is necessary to spray 0.2% 0.5% ferrous sulfate for prevention and control; magnesium deficiency, old leaves yellowing first, then new leaves yellowing, leaf veins still green, 0.7-0.8% boron magnesium fertilizer can be sprayed to control.

4, the temperature is too low: too low temperature will also cause leaf yellowing, as long as it is moved into the high temperature.

What are the reasons why mast flowers do not blossom?

1, improper water and fertilizer: once excessive water and fertilizer, it will cause plant overgrowth, reproductive growth without enough nutrients will affect the formation of flower buds, resulting in non-flowering or few flowering, some blooming, or even immediately fall off. In the period of flower bud differentiation, special attention should be paid to the collocation of phosphorus and potassium fertilizer, such as 0.2% potassium dihydrogen phosphate solution, which is conducive to flower bud formation and bud pregnancy; excessive fertilization and watering during the bud period will also cause falling flowers and seedlings.

2. The light is not suitable: Liriodendron likes shade. We should pay special attention to the strong light in summer and weak light in winter, which will affect the blossom.

3. High alkali content in soil: Jianzi flower likes acidic soil, and cultivated mast flower soil contains high salt and alkali, which will cause plant yellowing and eventually affect flowering.

4. Non-pruning and shaping: disorderly flowers and branches, a large number of miscellaneous branches consuming a lot of nutrients and branches too dense, affecting photosynthesis, are all important reasons for not blooming.

5. Serious diseases and insect pests: I believe everyone can understand that serious diseases and insect pests are bound to lead to the loss of flowers.

Culture method of Gardenia jasminoides: what if the leaves turn yellow?

Gardenia, also known as Gardenia jasminoides, originated in China. Gardenia leaves are evergreen all the year round, flowers are fragrant and elegant, green leaves and white flowers are particularly beautiful and lovely. It is suitable for front steps, poolside and roadside configurations, and grows well in patio, courtyard, shade or potted plants. It can also be used for flower hedges and potted plants, and flowers can also be used for flower arrangement and decoration. Gardenia likes warm, humid and sunny environment, more cold-resistant, semi-overcast, afraid of stagnant water, and requires loose, fertile and acidic sandy loam.

1. Selection of pot soil for gardenia culture

Gardenia flowerpot soil can be made of mountain mud, or 4 parts of rotten leaf soil (peat), 4 parts of vegetable garden soil and 2 parts of river sand. The upper pot plant had better be able to carry soil, the pot soil should be kept moist at the beginning of the pot, pay attention to shade, do not apply fertilizer temporarily, slow the seedling for 10 days and 15 days. And then gradually put it in a sunny place. The time to change the basin is usually from April to May.

two。 Temperature requirements of Gardenia jasminoides culture

Gardenia growth temperature of 20: 28%, late spring to early autumn, the weather is hot, pay attention to shade, high temperature, direct sunlight, and speed up air circulation, otherwise the leaves are easy to yellowing. Gardenia jasminoides planted in the ground was transplanted from March to April with soil masses. There is plenty of sunshine from late spring to early autumn, so it is necessary to spray water properly to cool and humidify. Potted gardenia can survive the winter in the open field in the south. The Huang-Huai River Basin moved into the greenhouse in the middle of October, and the room temperature was kept at 5: 12 ℃. More than 15 ℃ affected dormancy and growth in the coming year. Put it in a place with plenty of sunshine, good ventilation and suitable temperature in winter.

3. Watering method of Gardenia jasmine culture

In winter, we should pay attention to control watering, should be dry, the lower the temperature, the less watering, so that the concentration of somatic cells increases, which is helpful to resist the cold. Low temperature or basin soil is too wet, easy to cause fallen leaves, or even death.

Gardenia should be watered dry and wet. The soil is too wet, resulting in anoxia and asphyxiation of the roots, and the aboveground parts show yellow leaves and falling buds, especially after gardenia budding, the amount of watering should be controlled. Generally, water is watered every 2-3 days in spring and autumn, 1-2 times a day in summer and 5-7 days in winter. In addition, alum fertilizer and water are applied every half a month in summer, and usually spray water to the leaves to remove dust, which is conducive to plant growth.

4. Fertilization method of Gardenia jasminoides culture

Gardenia likes fertilizer, in addition to pot-changing application of organic fertilizer as base fertilizer, the growth period should also be diligent topdressing, it is appropriate to apply thin fertilizer frequently. During the growth period, organic liquid fertilizer was applied every 10 days or so, with 10%-15% concentration of cake fertilizer and water; after budding, quick-acting phosphate fertilizer was applied 2-3 times, such as 0.5% superphosphate and so on. Fat but autumn, fertilize after autumn, suddenly grow autumn branches, easy to suffer frost injury. During the growth period, combined with fertilization and watering, 0.2% ferrous sulfate was irrigated once every 15 to 20 days to prevent leaf yellowing.

5. The method of shaping and pruning in Gardenia Culture

Cutting off the top tip of Gardenia jasminoides to promote branching is beneficial to more flowering. Gardenia is mostly 3-forked branches, often forming staggered overlapping branches, seriously affecting ventilation and light transmission, resulting in thin and disordered branches, so timely pruning can form a beautiful plant type. Gardenia jasminoides is an evergreen shrub with large leaves and fat flowers, and the main branches should be few rather than more. First of all, it is necessary to cultivate an upright trunk, which can be branched. Buds are formed every April, so attention should be paid to preserving buds when removing branches from part of the trunk from April to May. Cut off immediately after the failure of flowers in June, which can reduce the consumption of nutrients and promote the development of new branches. When the new branch grows to 2-3 nodes, take out the heart for the first time and erase part of the axillary buds to avoid too many branches and cluttered. In August, the three forked branches were heart-picked and the crown was cultured, and the dignified and beautiful potted Gardenia jasminoides could be formed after 2-3 years.

6. Matters needing attention in Gardenia Culture

(1) Gardenia likes to be fat, but is afraid of thick fertilizer. Generally, the cake fertilizer containing more phosphorus and potassium is applied twice before budding, and the fertilization is stopped after budding. If too much fertilizer is applied, it is easy to burn roots and cause budding. During the growing period, rotten cake fertilizer water or manure fertilizer water was applied once every half a month, and 1%-2% ferrous sulfate was added to prevent soil alkalization.

(2) Gardenia prefers semi-shade, is afraid of strong light, and requires a shade degree of about 50%. If exposed to the sun, the leaves turn yellow and whiten until they fall off, so they should be kept in a shady place or a place with scattered light in summer. Make it see light in the morning and evening to prevent the leaves from yellowing.

7. Propagation methods of Gardenia jasminoides

Gardenia is mainly propagated by cuttings, and it can also be propagated by pressing, dividing plants, and sowing.

(1) cutting propagation

From May to June, select semi-lignified, fully developed twigs, cut them into 10 mures 15 cm long, soak the base with 1000 mg / kg naphthoic acid for 3 to 5 seconds, cut them in acid soil with strong water and fertility conservation, generally use 3 portions of rotten leaf soil or mountain mud, 1 part of sawdust, peat or river sand, take root about 1 month after planting, and transplant after 50 days.

The method of water insertion is often used in summer in the south, which is carried out from April to July. The cut cuttings, which are 15 centimeters long and with 2 or 3 leaves on the top, are inserted on the basket lid or perforated plastic board, and the lid or plastic plate is floated on the surface. The upper part of the insert can be exposed to the water. Put it in the semi-shade after insertion and keep the water temperature for 16-18 ℃. New roots can grow in 20 days. When the temperature is high, change the water frequently, change the water once a day, can not make the water deteriorate. When the root is 2-3 cm long, it can be transplanted.

(2) striping propagation

Most of them are carried out from May to June. Select 1-year-old, 2-year-old strong branches, 25 cm long, pressed into the soil 3 cm 5 cm, about 1 month can take root, 2 months later can be cut off from the mother. Can also be high pressure, that is, on the adult gardenia, choose 2-3-year-old strong branches ring peeling 1cm, and then wrapped in moist peat, the outside wrapped with plastic bags to keep the soil moist, about 40 days can grow new roots, 2-3 months later cut off the mother.

(3) ramet propagation

In May, there are 2 or 3 branches growing side by side at the base of the root, which can be cut from the root with a knife, and each ramet has fine roots. After the wound is coated with plant ash, it can be planted separately.

Note: the reason why the leaves of mast flowers turn yellow

First, improper moisture

A, too much watering, in this case, the tender leaves of the masts are dark yellow and dull, but there is no obvious change in the old leaves, so just take the flowers out of the pot and put them in a cool, ventilated place and put them back after the soil dries.

B, lack of water, leaf tip or edge withered, dry, old leaves withered and yellow shedding from bottom to top, but the growth of new leaves is relatively normal, at this time should be fully watered and thoroughly watered.

Second, improper lighting

A, the light is too strong, the sunrise part of the leaf appears macula, at this time only need to move it to the shade to maintain can be restored, the new leaves will no longer have macula.

B. when there is not enough sunlight, the leaves will turn yellow or even fall off, as long as you put them in the sun to replenish the sun.

Third, improper fertilization

A, excessive fertilization, mainly manifested in the brown appearance at the tip of the new leaves, the thickening and dullness of the leaves, and the scorched yellow shedding of the old leaves. At this time, it is necessary to stop fertilization immediately, and in serious cases, the soil should be washed to reduce the concentration. B, insufficient fertilizer will also cause plant yellowing, such as iron deficiency, the leaves are light yellow or white, and the leaf veins are still green, so it is necessary to spray 0.2% Moe 0.5% ferrous sulfate for prevention and control; magnesium deficiency, the old leaves turn yellow first, then the new leaves turn yellow, and the leaf veins are still green. At this time, 0.7%-0.8% boron and magnesium fertilizer can be sprayed to prevent and control.

Fourth, the temperature is too low, too low temperature will also cause leaf yellowing, as long as it is moved into the high temperature.

Note: the reason why the mast flower does not bloom

First, improper water and fertilizer, once excessive, it will cause plant overgrowth, reproductive growth without enough nutrients will affect the formation of flower buds, resulting in no flowering or few flowering, some blooming, or even immediately fall off. In the period of flower bud differentiation, special attention should be paid to the collocation of phosphorus and potassium fertilizer, such as 0.2% potassium dihydrogen phosphate solution, which is conducive to flower bud formation and bud pregnancy; excessive fertilization and watering during the bud period will also cause falling flowers and seedlings.

Second, the light is not suitable, Jiaozi flowers like shade, we should pay special attention to the strong light in summer and too weak light in winter, too strong and too weak will affect the blossom.

Third, the soil contains high alkali, Jianzi flower likes acidic soil, cultivated mast flower soil contains high salt and alkali, it will cause plant yellowing, and eventually affect flowering.

Fourth, no pruning and shaping, messy masts and branches, a large number of miscellaneous branches consuming a lot of nutrients and branches too dense, affecting photosynthesis, are all important reasons for not flowering.

Fifth, diseases and insect pests are serious. I believe everyone can understand that serious diseases and insect pests are bound to lead to the loss of flowers.
