How to breed potted gardenia and precautions

Gardenia planted in the soil is different from gardenias planted in pots. Gardenias in the soil do not need to be managed as long as they are alive, but gardenias in pots always need to be managed. Come with the female net to see how to raise potted gardenias and how to reproduce gardenias.

Culture methods and matters needing attention of potted gardenia flower

The first step: choose the appropriate basin soil. Gardenia jasminoides is an acid-loving flower with a suitable pH value of 5 to 6. If the soil acidity is not suitable, it will get twice the result with half the effort in the future management. 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 of gentleman orchid soil is more convenient and practical.

The second step: rational fertilization. Gardenia likes to be fat. 3% rotten cake fertilizer can be added to the culture soil as base fertilizer. During 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.

Step 3: scientific watering. Gardenia likes moist soil and high air humidity. Keep the soil moist during the growth period from April to September. 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.

Step 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.

Step 5: winter dormancy is good. Gardenia can survive the winter in the 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.

The sixth step is proper 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.

Step 7 change the basin soil at the right time. The seedlings are planted in small pots and gradually replaced 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.

How to raise Gardenia jasminoides

Northern conservation of Gardenia jasminoides is often due to climate, soil and other conditions are not suitable for its growth and development, resulting in the leaves of Gardenia jasminoides turned yellow and even the whole plant died. For this reason, the northern conservation of Gardenia jasminoides must master the following points.

Gardenia jasminoides has strict requirements on the soil and grows well in the acidic soil of pH5-6, while the soil in the north is generally neutral or alkaline. In this soil, iron hydroxide insoluble in water is formed due to the hydrolysis of iron salt, which can not be absorbed by plants, resulting in serious iron deficiency in plants. Although iron is not a component of chlorophyll, it is a necessary condition for the formation of chlorophyll, so iron deficiency blocks the synthesis of chlorophyll, so photosynthesis can not be carried out normally, which is the main cause of plant starvation and death.

In addition, iron is a component of some oxidases and plays an important role in respiration. If iron deficiency, it will affect the normal physiological activities of the plant. To solve the problem of iron deficiency, the method of watering "alum fertilizer water" can achieve good results. In addition, a small amount of black alum powder can also be added to the basin soil, the dosage is 0.5% of the weight of the basin soil, and 0.5% of 1.0% black alum water is poured every 10-15 days during the growing season, which can also ensure the iron requirements of gardenia, so that it can grow and develop normally.

Most of the soils in the north are neutral or alkaline, which leads to the lack of iron that can be used by plants, which is one of the main reasons for the yellowing of leaves. For this reason, fertile acid culture soil should be selected for the culture of Gardenia jasminoides. Generally, it can be mixed with 4 parts of rotten leaf soil, 4 parts of garden soil and 2 parts of sandy soil. Then per kilogram of soil mixed with 1 kilogram of sulfur powder. Watering gardenia jasminoides with big leaves is suitable to use Rain Water or fermented rice water. During the growth period, 0.2% ferrous sulfate is watered every 10-15 days or alum fertilizer water is applied every 10-15 days (the two can be carried out alternately). This can not only prevent the soil from becoming alkaline, but also replenish iron to the soil in time, thus preventing the leaves from turning yellow.

Leaf gardenia likes to be moist, in addition to the usual need to keep the basin soil moist, but also must often pay attention to increase air humidity. This is because the climate of the north is different from that of the south. The north is dry in spring, often blows dry winds, strong light intensity in summer, hot weather, and cold and dry winter. Therefore, in spring and summer, it is necessary to spray foliage with clear water every morning and evening and sprinkle water to the nearby ground to increase air humidity. Watering should be less in winter, but branches and leaves still need to be sprayed and washed frequently to keep the leaves clean.

Gardenia jasminoides likes light, but is afraid of strong light exposure. If exposed to the sun, the leaves turn yellow and whiten until they fall off. Therefore, the summer must be placed under the shade or in a place with scattered light, so that it can see some sunlight in the morning and evening, so as to prevent the leaves from turning yellow. Gardenia jasminoides is not cold-resistant, so it is necessary to pay attention to the room and out of the room. It is generally entered in the middle of October and placed in the sunny place, and the room temperature should be kept at 10 ℃-12 ℃. It is not advisable to leave the room too early in the next spring, usually in late April. If the above four points can be achieved, gardenia jasminoides can not only settle down in the north, but also have numerous green leaves and fragrant flowers.

How to reproduce gardenia:

Although it is convenient to reproduce the striping, if the plant is too large and the lower branches have been lignified, the crimping will be a little troublesome, because the pressure is too heavy, easy to break, too light to take root. The best way is to select biennial branches in April. About 20cm to 25cm long, buried in the soil. Keep moist, take root for about 30 days, separate from the mother plant in summer, and separate in the following spring.

Cutting propagation is the most convenient, survival rate of a higher method, only in the rainy season cut off about 15CM branches (with more than three nodes), and then remove the bottom leaves, leaving the top of the new buds, and one or two mature leaves, respectively minus half, or do not leave mature leaves, as long as the new buds are not too small, and then cut on the seedbed, keep moist, 10 color 12 days will take root.

This is the end of the potted gardenia. Potted gardenia must pay attention to the changes in the soil, otherwise it is easy to die, and potted gardenia is still a little expensive.

Cultivation methods and matters needing attention of potted Gardenia jasminoides

Gardenia is a common home breeding plant, evergreen all the year round, fragrant and elegant flowers, particularly beautiful and lovely, is a home plant that many people like to breed. So how to raise the potted gardenia at home? The following is a detailed introduction of gardenia culture methods and matters needing attention.

Introduction of Gardenia

Gardenia, also known as Gardenia, originated in China, mainly distributed in Sichuan, Jiangsu, Zhejiang, Anhui, Jiangxi, Guangdong, Yunnan, Fujian, Taiwan, Hunan and other places. 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.

How to grow gardenia in potted plants

I. Propagation mode of gardenia

Cutting method

The branches of Gardenia jasminoides are easy to take root, the warm ground in the south is often in March-October, and the north is often cut in May-June, cutting sturdy mature branches and planting them on the sand bed. As long as they are often kept moist, they are very easy to take root and survive. Water insertion is far better than soil insertion, with a survival rate of nearly 100% from April to July. Cut cuttings retain only the top 2 leaves and terminal buds in containers filled with clear water, often change water to avoid incision decay, and begin to take root after 3 weeks.

Strip pressing method

It is generally carried out before and after the Qingming Festival in April or in the Meiyu season. In April, one-year-old strong branches are selected from the 3-year-old mother plant, which are 25cm long and 30cm long. They are pulled to the ground, and the buried parts of the branches are scratched. If they can be dipped in 200ppm powder acetic acid and then covered with soil compaction, it is easier to take root. If there are trigeminal branches, you can get three seedlings at the fork at a time. Generally, it can take root after 20-30 days, can be separated from the mother plant after rooting in June, and can be planted separately with soil or a single plant in the next spring.

Spring is the best way to transplant seedlings or potted plants, and it is necessary to bring soil balls in the rainy season. Keep the soil moist during the growing period, and water more during flowering and midsummer. Fertilize once a month and increase phosphorus and potassium fertilizer before flowering. Pruning and shaping in the early spring of the following year, and cut off dead branches and long branches in time.

Sowing method

Generally choose full, dark red ripe fruit, even shell sun or dry as a seed, before sowing, use scissors to cut the seed pericarp, dig out the seed, rub in hot water to disperse, remove floating seeds or impurities, and then remove the sunken full seed, spread it on the bamboo mat, put it in a ventilated place to dry too much moisture. Generally choose Xiangyang hillside or Tufang, the soil layer is deep, loose and fertile sandy loam sowing, you can use the field edge corner planting, or interplanting with legumes. Before planting, plough the land 1 to 1.5 feet, remove miscellaneous trees, set up the border according to the width of 4 to 5 feet (the soil quality is better, the distance can be larger, otherwise it is smaller), the border is 6 inches high, and soil manure, green manure or human and animal manure can be used as base fertilizer, for example, 20,30 piculs of human manure per mu should be applied, and the soil should be raked after the soil is dried to level the border surface. Sow the ditch at a distance of 6 to 7 inches on the border surface, and the ditch is about 1 inch deep to be sown.

Gardenia can be sowed in spring or autumn, generally in spring, spring sowing before and after Rain Water, autumn sowing before and after the Autumn Equinox, seeds mixed with fire ash evenly sown in the sowing ditch, and then cover the flat sowing ditch with fine soil or fiery soil, cover the grass with water, and often keep the soil moist to facilitate seedling emergence, with seeds of 4 kilograms per mu. After emergence, we should pay attention to remove the cover grass in time, weed frequently in the seedling stage, be careful not to hurt the roots of the seedlings, need to dilute human feces and urine after weeding, and can be transplanted after raising seedlings for one year. If the transportation is far away, it is appropriate to use yellow mud slurry root, cover grass to moisturize, plant one plant in each hole, cover soil, compaction, and sprinkle water. After planting, weeding and topdressing is applied once every spring and summer, which can be applied to human and animal manure, barnyard manure, compost, cake fertilizer and so on. Before flowering in summer, it is better to apply fertilizer with more phosphorus and potassium content, and fertilization is generally carried out after weeding and loosening the soil.

2. Culture methods of potted gardenia.

1. Soil selection

Gardenia jasminoides is an acid-loving flower with a suitable pH value of 5 to 6. If the soil acidity is not suitable, it will get twice the result with half the effort in the future management. 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 of gentleman orchid soil is more convenient and practical. For example, alkali in soil, water and fertilizer makes the plant unable to absorb iron, thus affecting the formation of chlorophyll, withering branches, scorching leaves, and even death.

2. Methods of reproduction

Cuttings and striping propagation are commonly used. Cuttings, which are 15 hundred meters long with twigs in the rainy season, are planted in the seedbed and take root in 10-12 days. In April, biennial branches were selected, 20-25 cm long, buried in the soil, kept moist, rooting for about 30 days, separated from the mother plant in summer, and planted in the following spring. Transplant seedlings or potted plants, spring is better, in the plum rain season, need to bring soil balls. Keep the soil moist during the growing period, and water more during flowering and midsummer. Fertilize once a month and increase phosphorus and potassium fertilizer before flowering. Pruning and shaping in the early spring of the following year, and cut off dead branches and long branches in time. Related recommendation: propagation method of Gardenia jasminoides

3. Upper basin

The pot of gardenia jasminoides should be planted around April, and the pot soil should be loose and slightly acidic. After planting, pour enough water, put it in the outdoor semi-shady place, usually pay attention to watering and foliar spray, after taking the basin for about 15 days, turn to normal maintenance.

Daily maintenance and matters needing attention of potted Gardenia

1. Watering

How to water gardenia culture

Gardenia likes moist soil and high air humidity. Keep the soil moist during the growth period from April to September. 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.

2. Fertilization

In May, topdressing fertilizer in time, applying nitrogen and phosphorus integrated fertilizer for 1 to 2 times. At the same time, pay attention to the basin soil should not be too wet, avoid poor drainage or stagnant water after rain, otherwise it will cause leaves or buds rot and can not blossom. Gardenia like fertilizer, it is appropriate to apply fermented bean cake, sesame sauce dregs, peanut bran and other fertilizers, after fermentation can be acidic, but must be thin fertilizer, avoid thick fertilizer, raw fertilizer, do not apply fertilizer during hibernation. If you have been planting for less than three years, do not give human faeces and urine. Too much nitrogen fertilizer will result in thick branches, large leaves, thick green, but no flowering. Lack of phosphorus and potassium fertilizer will also appear the phenomenon of non-flowering or bud withering and shedding.

3. Lighting

Gardenia likes shade and must not be exposed to the hot sun, but some people often mistakenly think that gardenia requires full shade, resulting in mistakes in cultivation. In fact, while paying attention to cultivating its shady environment, it is necessary to maintain 60% light throughout the day in order to meet its growth needs. Summer and autumn to prevent the hot sun exposure, lest the leaves withered, affecting the ornamental. Thin fertilizer is applied once every 10-15 days in April, and you can't water too much with buds. This flower is afraid of waterlogging, and its leaves turn black as soon as it is waterlogged.

4. Humidity

Like humidity, if the air humidity is less than 70%, it will directly affect flower bud differentiation and bud growth, but too wet will cause root rot and branch withering, leaf yellow shedding phenomenon. In addition to normal watering, foliar and nearby ground should be sprayed with clean water frequently to increase air humidity appropriately. Don't pour too much water when you have a bud, or it will cause buds to fall. It is necessary to apply phosphorus and potassium fertilizer and thinning buds to prevent falling buds. Generally, when you see the soil dry, you use your hand to flick the earthen pot (like a watermelon). When you hear the empty sound of Dangdang, you water it until the bottom is leaking. The water is watered with the tap water of the previous day and left for a day and a night. The water is mixed with rice water, lemon peel, broken bones, eggs, soy milk and other rotten upper layer fat water, which is a little smelly, but it will disperse after a while. Or put the rice panning water for a few days, turn sour and pour it on the roots.

5. Temperature

Liking temperature: 18 ℃ to 22 ℃ in the growing period, 5 ℃ to 10 ℃ in the overwintering period, and freezing if the temperature is lower than-10 ℃.

6. Placement of potted plants

Gardenia likes semi-shade, potted plants should be placed in semi-shady place to maintain, avoid summer sun exposure. Winter should be appropriate anti-freezing to keep warm, placed in the south, shelter, warm balcony or greenhouse for the winter.

7. Timely pruning

Gardenia needs pruning at the right time.

Gardenia jasminoides has strong sprouting power, easy to overlap branches, airtight and dispersed nutrition. In normal shape, three main branches should be selected according to the shape of the tree, and other branches sprouting from root tillers should be cut off at any time. After the flowers fade, the branches should be truncated in time to promote the germination of new branches under the cut mouth. Pick the heart after the new branch grows three nodes to avoid growing blindly.

8. Change the basin soil at the right time

The seedlings are planted in small pots and gradually replaced 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.

9. Winter dormancy

Gardenia can survive the winter in the 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.

10. Prevent yellowing

There are four causes: iron deficiency in ①. Soil contains too much calcareous, alkali, phosphorus, manganese, etc., which will affect the absorption of iron by plants, affect the formation of chlorophyll, make the veins of tender leaves green, spread throughout the leaves, and can be applied with 1 inch 500 ferrous sulfate or 0.2% black alum water, once every 10 days. ② is magnesium deficient. Acid red soil and excessive potassium and ammonium are prone to magnesium deficiency, which makes the veins of the old leaves in the lower part of the plant green and yellow, which can be sprayed with 1% to 2% magnesium sulfate solution, but excessive application of magnesium will cause calcium deficiency and hinder the development of xylem in roots and stems. ③ basin soil is too wet or too dry. ④ is exposed to the sun in summer.

11. Diseases and insect pests

Leaf spot disease and chlorosis often occur. Leaf spot disease is sprayed 600 times with 65% Dysen zinc wettable powder, and 0.1% ferrous sulfate solution is regularly added to watering to prevent chlorosis. The insect pests are harmed by stinging moths, shell insects and whiteflies, which are sprayed with 2.5% EC 3000 times and 40% omethoate EC 1500 times to kill shell insects and whiteflies.

Culture methods and matters needing attention of Gardenia jasminoides how to cultivate Gardenia jasmine

Gardenia is a famous fragrant flower. When it comes to the season of gardenia blooming, vendors selling gardenia can be seen everywhere on the street. Many people like to put it in a vase and watch it. In fact, if we want to retain the aroma of gardenia for a long time, why don't we breed it ourselves? Now gardenia can also be cultivated as bonsai, so what are the breeding methods and matters needing attention of gardenia? Next, the editor of Weather Network will teach you how to raise gardenia.

Culture methods and matters needing attention of Gardenia jasminoides

Top1 chooses suitable basin soil

The cultivation of any bonsai flowers requires some requirements for basin soil. Gardenia is suitable for acidic soil, and the best PH value is between 5 and 6. If the choice of soil in the first step is not suitable, it will be more troublesome to change the basin soil in the future.

Breeding gardenia generally choose rotten leaf soil and peat soil plus general garden soil, can not use cinder, the most convenient is to buy the special soil of magnolia, which is also applicable to gardenia.

Top2 lighting requirements

Gardenia is a sunny plant and can not be cultivated completely as an indoor plant. In particular, gardenia in the growing season to meet sufficient light, such as spring and autumn, gardenia flowerpot can be moved to the place of light. Of course, in the summer when the sun is burning, it should be shaded at noon to avoid being exposed to the sun to death.

Top3 temperature requirement

Gardenia is actually very suitable for the growth of the environment, but the best growth temperature is between 18 ℃-22 ℃. If it is below minus 10 degrees Celsius, it is easy to freeze. The weather in the south is very suitable for the growth of gardenia.

In summer, gardenia can be moved to a well-ventilated, humid and transparent shade.

In winter, gardenia can be placed in the positive outdoor, let it grow naturally, breeders do not have to worry too much.

Gardenia flower pot cultivation

Top4 water demand

Gardenia likes a humid environment and needs to meet the water demand during the growing period. Each watering should be thoroughly watered, the summer weather is dry, we can spray water to the page 2 or 3 times a day to increase the humidity of the air around the period. But flower bud period of gardenia watering should pay special attention, should not be too much, lest the buds fall off.

Demand for nutritious Fertilizer in Top5

Gardenia likes fertilizer, but pay attention to thin fertilizer, do not apply too much fertilizer or thicker fertilizer at one time. In order to ensure that the slightly acidic soil will not be destroyed in the process of fertilization, we can mix the ferrous sulfate prepared into the fertilizer solution. Four months after the peak season of gardenia production, you can top up once every half a month.

Gardenia bonsai

Top6 pruning

Gardenia is easy to overlap branches in the growth process, which can easily lead to airtight and dispersed nutrients, which is not conducive to the healthy growth of gardenia, so cut off some branches according to the real-time demand.

After the gardenia blossoms every year, it can be trimmed lightly to trim off the weak and morbid branches and leaves, which will help gardenia to absorb sufficient nutrition.

Other points for attention in Gardenia Culture

The main results are as follows: 1. The propagation method of Gardenia jasminoides is cutting method, pressing method and plant division method.

2. Pay attention to the disease and pest control of gardenia. Gardenia is generally prone to yellow horse disease. In addition, leaf spot disease and canker occur from time to time. We should pay more attention to it. Gardenia is also easy to be attacked by a kind of whitefly pest. If you encounter it, you can consult a professional for pest control.

3. Gardenia is very sensitive to water, so a tile basin with good permeability should be used as the bottom of the basin, so that watering gardenia will not cause stagnant water, resulting in yellowing and shedding of leaves, and even death of flower plants in serious cases.

4. As for the cutting time of Gardenia jasminoides, the first half of the year is in April, and the second half of the year is from August to September, which is the best season for gardenia to multiply.

5. It is not suitable to apply fertilizer before and after gardenia cutting. At this time, it only needs to grow naturally, even if it is natural fertilizer, urea, chemical fertilizer and so on.

In fact, the cultivation of gardenia is not difficult, as long as according to the above gardenia breeding methods and matters needing attention step by step, there will not be too big mistakes, and its own vitality is very exuberant, such as wild gardenia growing healthily in the natural environment, as long as we do what we should do, we can sit and wait for the fragrance of gardenia to float around in the coming year.
