Introduction to the correct culture method of gardenia flower

Gardenia, also known as Gardenia, Yellow Gardenia, is an evergreen shrub of Gentiana, Rubiaceae and Gardenia. Gardenia has luxuriant branches and leaves, evergreen leaves and fragrant flowers. It is an important ornamental plant in the courtyard.

Gardenia likes warm, moist, adequate light and well-ventilated environment, but avoid strong light exposure, suitable for living in a slightly shaded place, resistant to semi-shade, afraid of stagnant water, cold-resistant, suitable for planting in loose, fertile and well-drained light clayey acidic soil, is a typical acidic flower.

The correct breeding method is not tight can feed gardenia, but also can raise gardenia, general gardenia, nothing more than soil, fertilizer, water, environment, we talk about gardenia breeding methods one by one.

First of all, gardenia flower friends know that gardenia is a typical acidic flower, and the local soil and water of many flower friends in the north are alkaline, so special attention should be paid to breeding, and it is best not to use pastoral soil. you can mix your own soil with 40% garden soil, 15% coarse sand, 30% stable manure soil, 15% rotten leaf soil, or with special nutrient soil.

Then when it comes to water, we said that gardenia is a typical acidic flower, so direct watering of tap water does not help to improve soil acidity and alkalinity. Rain Water or fermented rice water can be used for watering. If it is tap water, it should be hung for 2 to 3 days before use. Watering 0.2% ferrous sulfate (black alum) water or applying alum fertilizer water every 7 to 10 days during the growing period can not only prevent soil alkalinization, but also supplement iron in the soil, which can not only prevent leaves from yellowing, but also make leaves greenish and bright, flowers hypertrophy.

Flowers large, white, fragrant, with short pedicels, solitary branches apical. The flowering period is longer and blossoms continuously from May to June. Do you know how to cultivate and care for gardenia? Come and have a look with the editor.

1. Living environment of 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.

Soil demand

Gardenia likes to grow in acidic soil, so when buying gardenia soil, pay attention to choose acidic soil for culture.

Suitable growth temperature requirement

According to the growth temperature of Gardenia jasminoides, the best growth temperature is 16 ℃-18 ℃, but it should be noted that too high or too low temperature is not conducive to the growth of Gardenia jasminoides.

Plenty of water

Gardenia likes warm, humid and sunny environment, so it is also very important for water demand and air humidity. During the growth of Gardenia jasminoides, we should pay attention to increasing the amount of water.

Plenty of light time

During the growth period, gardenia should also pay attention to the need for appropriate amount of light. Gardenia is a plant that loves light.

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.

Here are the common culture problems of gardenia:

How do gardenia survive the winter?

According to the growth habits of gardenia, it will enter the dormant period in winter. It does not matter that the leaves of gardenia fall or stop growing during the dormancy period. When gardenia overwintered, it is best to put it in the coldest room where astigmatism can be seen. The temperature should not exceed 12 ℃, and 610 ℃ is the most appropriate. Water once a month, or according to the dry and wet condition of the home, the basin soil is thoroughly watered. Be careful not to freeze the gardenia in winter. In short, gardenia can not be put in a place where the temperature is too high, nor can it be frozen when it is overwintering; it can neither be put in a sunny place nor without sunshine; it cannot be watered too much, nor can it dry the flowers to death. If gardenia continues to grow in winter, it can only be a waste of nutrients, which will affect the flowering in the coming year. The correct way is to let the gardenia in a natural dormancy in winter, wait until April of the next year, cut off all the old branches 2 cm above the branch of the gardenia, and then move outside to let it be exposed to the wind and the sun. If there are no conditions for the gardenia room at home, keep it away from the window and keep it ventilated.

Question: how to raise gardenia?

Answer: I have gardenia at home. It likes to be wet and likes diffuse light. If you must apply ferrous sulfate in the north, it will be easy to raise in the south.

Question: how to keep gardenia from falling leaves and flowers?

Answer: every year, collect the orange peel you have eaten and ferment with the soil. Use this soil to change the basin the next year to ensure that your gardenia is green. At the same time, watering can also be watered with soaked orange water. This method is simple, common in the north and south, and works very quickly! My gardenia was supposed to be dead this year, but after this method, the leaves became bigger and thicker, and it is estimated that the flowers will come next year! If you try and find it useful, you can have fun. I learned this prescription only this year. There is a neighbor old woman's gardenia is very good, she said she is such a kind of. My big gardenia leaves now have a lot of new buds, and another advantage of this method is that you don't have to worry about burning seedlings with more fat! If the potted soil is too poor, you can add a few compound fertilizers at the right time!

Question: how is gardenia leaf yellow going on?

Gardenia leaf yellow is due to iron deficiency, ferrous sulfate solution can be added.

Curing methods of Gardenia jasminoides

Gardenia is not only a good helper to improve the home environment, but also an expert in improving the air quality of the community, so how can we maintain it to make it grow better?

First, do a good job in breeding. We know that the reproduction of gardenia can be divided into sexual reproduction and asexual reproduction.

1. Sexual reproduction: ripe fruits with full and dark red color are generally selected, dried or dried. Before sowing, cut the pericarp of the seeds with scissors, dig out the seeds, rub the seeds in hot water, remove floating seeds or impurities, then fish out the sunken full seeds, spread them on the bamboo mat, put them in a ventilated place to dry off excessive moisture, and generally choose to sow seeds on sunny slopes or soil workshops, which are deep, loose and fertile sandy loam. Gardenia can be planted at the edge of the field or interplanted with legumes. Gardenia can be sowed in spring or autumn, usually in spring, sowing in spring before and after Rain Water, sowing seeds before and after the Autumn Equinox in autumn, sowing seeds evenly in the sowing ditch, then covering the flat sowing ditch with fine soil or fiery soil, covering the grass with water, often keeping the soil moist to facilitate seedling emergence, using 4-6 jin of seeds per mu. Attention should be paid to removing the cover grass in time after emergence, weeding should be done frequently at the seedling stage, and care should be taken not to hurt the roots of the seedlings. After weeding, it is necessary to dilute the human feces and urine, and the seedlings can be transplanted after one year. If the transportation is far away, it is appropriate to use yellow mud roots, cover grass to moisturize, plant one plant in each hole, cover soil, compaction and water, and apply weeding and topdressing once every spring and summer after planting. Human and animal manure, barnyard manure, compost, cake fertilizer and so on can be applied. 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. Asexual reproduction: cutting method-can be divided into spring cutting and autumn cutting. Cuttings choose healthy 2-3-year-old branches, cut 10-12 cm, cut off the lower leaves, the top two leaves can be retained and cut off half of each, first dipped in vitamin B12 injection, and then obliquely inserted in the bed, leaving only one section above, pay attention to shade and maintain a certain humidity, transplant or plant on a pot when rooting seedlings begin to grow It can blossom after two years, and in the south, the cuttings are propagated by water insertion, that is, the cuttings are inserted on a disc woven with Reed stalks, leaving them floating on the water, so that the lower part of them takes root in the water, and then transplanted and cultivated. The striping method in April selects an one-year-old strong branch from the 3-year-old mother plant, which is 25cm long and 30cm long, pulls it to the ground and cuts the buried part of the branch. If you can dip an appropriate amount of powder into acetic acid in the injured part. Then covered with soil compaction, it will be easier to take root.

Second, there are special points to pay attention to in nursing gardenia at ordinary times.

1. Give it an acidic environment. The alkali content in soil, water and fertilizer all made the plant unable to absorb iron, but affected the formation of chlorophyll, withered branches, scorched leaves, and even died. To use fertile, loose, well-drained acid soil, such as pine sawdust thoroughly mixed into the soil, the use effect is also very good.

The above is for you to explain the characteristics and efficacy and role of gardenia, more household plants, please pay attention.
