Today s news: How to raise gardenias?

If you want it to grow fast, you must give it the right growing conditions: light needs to be sufficient but not excessive; The flower soil is best with high nutrient content and weak acidity; Not too much water; Flower fertilizer needs to be replenished in time; It is also necessary to be careful not to leave it unsoiled for a long time. ”

Gardenias are suitable for warm, moist environments, but they can also grow in semi-shade. About five hours of sunshine a day, avoid direct sunlight, and fully photosynthesize in the morning or afternoon when the sun is weak. Spring and summer can be properly fertilized once a half month, and fertilization can be stopped when the temperature reaches below 15 degrees Celsius in autumn, so that it can gradually enter the dormant state In winter, it is necessary to pay attention to the insulation and ventilation of gardenias to ensure the flowering state of the next year.

1.Gardenias prefer acidic soils; 2.Gardenias are suitable for growing at a temperature of 16 to 18 degrees Celsius, preferring shade, and the temperature cannot be too high or too low; 3.

Gardenias like moist air, hot and dry summer, and must be sprayed 2-3 times a day to increase air humidity and help cool the plants. However, after the flowers have buds, they should not be watered too much, so as not to cause buds. It is better to water dry in winter to prevent water from rotting roots; 4.

Gardenias like fertilizers and acidic environments, and ferrous sulfate can be mixed into fertilizer in advance.

Gardenia words. According to the normal flower nourishment, it can be watered, fertilized and nutrients. Hope it helps.

Gardenias, which have just been bought, need to check its basic situation. If it is a seedling that has just grown from cuttings or the roots are shallow, then the buds and leaves should be cut off in time, and the roots should be quietly waited for the growth to be perfect, so as to prevent too much influence from being separated, affecting its rooting and adaptation to the environment.

1.Soil: When you just buy it, you should pay attention to ensure the air permeability of the soil, and the air permeability may be blocked due to bumps during transportation.

Clear the ventilation holes at the bottom of the pot and clean up the debris such as stones on the surface of the soil. Under normal circumstances, unless the soil is seriously compacted, the pot is broken and other special circumstances, it is necessary to wait for about a week of adaptation period before changing the pot.

2.Light: Gardenia has just been bought back because of the change of the environment will become slower to grow, at this time if he is placed in a soft light area with plenty of light, he can better adapt to the change of environment.

However, there should be no strong sunlight, and too strong environmental changes may cause it to wither due to inability to adapt.

3.Fertilization: Flowers brought back from the flower market are generally not fertilized at first.

Because on the one hand, florists will scientifically breed and fertilize; On the other hand, gardenias that have just changed their environment grow more slowly and require fewer nutrients. If the leaves suddenly turn yellow in a large area, a small amount of fertilizer containing a ferrous sulfate solution can be applied.

The steps to have a retardation are as follows:

1. Replace the potting soil: choose peat soil, sandy loam soil, and river sand to mix and prepare soil. 2. Astigmatism irradiation

Gardenias need to be kept in a place with soft astigmatism. 3. Water replenishment: After transplanting gardenias, they need to be watered once to make the root system fit closely with the soil.

4. Fertilization management: apply organic fertilizer every ten days during the growth period.

Gardenia, a shrub plant of the Rubiaceae family, the young branches are often slipped by short hairs, the branches are cylindrical, gray; Leaves oblong-lanceolate, obovate-oblong; The flowers are fragrant, and the single flower allows the worship to be born at the top of the branches; fruit ovate, nearly spherical or oval, yellow or orange-red; Seeds numerous, nearly rounded and slightly angular; The flowering period is 3 July, and the fruiting period is May and February of the following year.

In the "Compendium of Materia Medica", gardenia is called "zi", "the same as "卮", and its fruit is like the bronze wine vessel "卮" in the Shang and Zhou dynasties, so the ancients called it "gardenia". Gardenia is native to China and is now distributed in Shandong, Jiangsu, Anhui, Zhejiang and other places in China; It is distributed in Japan, Korea, Pakistan, the Pacific Islands and the northern part of the Americas. Born in wilderness, hills, valleys, hillsides, shrublands or forests by streams at an altitude of 10 1500 m; It is suitable for growing in loose, fertile, well-drained, lightly cohesive acidic soil; The propagation methods include seed propagation and cuttings propagation.

Gardenia has the effect of purging fire and removing trouble, clearing heat and dampness, cooling blood and detoxifying, and can treat symptoms such as eye heat and red pain, chest and heart, large and small intestines, and heat in the stomach

1. Potting soil.

Gardenias prefer acidic soils, with a suitable pH of 5 to 6, so prepare suitable soil before planting. If the pH of the soil is not suitable, it will be troublesome to maintain it later.

Cultivation soil usually chooses humus soil, peat soil and half of the garden soil, do not use cinder, or directly buy gardenia special soil, which is convenient and practical.

2. Fertilization. Gardenias like fertilizer, and when planting, rotten cake fertilizer is added to the soil as base fertilizer.

During the growing season, it is made of cake fertilizer and ferrous sulfate, and it is watered once a week. Organic liquid fertilizer with full nutrition can also be used.

Top dressing 1 2 times at the budding stage, watering the aqueous solution of potassium dihydrogen phosphate can make the flowers hypertrophied and fragrant.

When the temperature is above 35 in summer and 15 in autumn, stop fertilizing.

3. Watering. Gardenias prefer moist and moist environments. 4 During the growing period in September, keep the potting soil moist, watering to see dry and wet, and spray the leaves at night to keep the humidity. If the plant is growing too vigorously, do not water it at night, and water it in the morning when the sun comes out.

In the northern alkaline water area, when watering, leave the tap water for one day and then water. 3 5 days, pour a little citric acid aqueous solution, can keep the leaves green.

Fourth, light. Gardenias need plenty of sunlight to grow, and if they are left in the semi-shade for a long time, the flower branches will be thin and slender. In maintenance, except for the need for shade at noon in July and August and winter hibernation, other times can be maintained in the sun.

1. Soil.

Cultivating gardenias requires attention to the soil, which must be soft, breathable, permeable, fertile and acidic. It can be mixed with peat soil and humus soil in a ratio of 1:1.

It can also be mixed with peat, perlite and vermiculite, the ratio is 4:1:1, and finally a small amount of pine needle soil can be mixed to improve soil acidity.

2. Illumination. Gardenias like light, it is best to put them in a bright place during the maintenance period, more sun can promote better photosynthesis, the leaves are green, and they can also bloom as scheduled. Note that the sunlight in summer is too strong and must be blocked in time, otherwise it is easy to get sunburned. The light in winter is soft, and it can be placed in a well-lit place all day long, and more sun is conducive to wintering.

3. Temperature. Gardenias prefer warm environments, and the temperature suitable for its growth is between 20 and 28, and it is not cold tolerant. After the temperature drops to 10 in winter, you need to move indoors, and the temperature should be controlled above 10 to avoid frostbite. Also, watch out for the high temperatures in the summer.

When the temperature exceeds 32, it is necessary to strengthen ventilation and spray water frequently to help it cool down.

Fourth, watering. It consumes more water during the growing season, and when the soil is dry, it is necessary to replenish water in time to ensure that the soil is moist. Note that it is afraid of waterlogging. The amount of watering must be well controlled, the soil can be slightly wet, and it is strictly forbidden to accumulate water.

Not only soil moisture is required, but also a certain air humidity. If the climate is drier, you need to spray water frequently to increase the humidity. Do not spray on the flowers during flowering to avoid early wilting of the flowers.

5. Fertilization. Gardenia is a fertilizer-loving plant, not only to apply base fertilizer when planting, but also to timely top dressing during the growing season. Usually you can apply well-rotted organic fertilizer, and before flowering, you should apply phosphorus and potassium fertilizer. Potassium dihydrogen phosphate can be diluted and sprayed with fertilizer on the plant, which is quickly absorbed and conducive to flowering.

Cultivation of gardenias.

1. Soil: Gardenia is an indicator plant of acidic soil, so the slightly acidic environment of the soil is the key to determining the growth of gardenia. The culture soil should be mixed with 7 parts of slightly acidic sandy loam laterite and 3 parts of humus. It is advisable to control the pH value of the soil in between.

2. Temperature: The optimal growth temperature of gardenia is 16 -18. Low temperature and direct sunlight are extremely unfavorable for its growth, so it is advisable to maintain gardenias in a sparse forest or shade shed with good ventilation, high air humidity and light transmission in summer.

In winter, it should be placed in an environment with sunlight and a temperature not lower than 0, and let it dormant, as too high a temperature will affect the flowering of the next year.

3. Moisture: Gardenias like moist air, and watering should be increased appropriately during the growth period. Usually the potting soil can be watered when it is white, and it can be watered thoroughly at one time.

In summer, it is hot and dry, and it is necessary to spray the foliar surface 2-3 times a day to increase the humidity of the air and help the plants cool down. However, after the flowers have buds, they should not be watered too much, so as not to cause buds. It is better to water dry in winter to prevent water from rotting roots;

4. Fertilizer: Gardenia is a fertilizer-loving plant, in order to meet its demand for fertilizer during the growth period, and to maintain the slightly acidic environment of the soil, ferrous sulfate can be mixed into the fertilizer solution in advance for fermentation. After entering the peak growing season in April, you can top dressing once every half month (it is best to mix more water when fertilizing to prevent flower burning).

In this way, it can not only meet the fertilizer demand of gardenia, but also keep the soil environment in a relatively balanced slightly acidic environment, prevent the occurrence of yellowing, and at the same time avoid the sudden supplementation of ferrous sulfate, local acid damage to gardenia.

5. Reproduction: Although there are many ways to propagate gardenias, the easiest and fastest is the floating water insertion method, first find a foam board, and punch holes in it, cut off the half-ripe branches of the gardenias, insert them into the holes of the foam board, and then put the foam board into a bucket filled with water, put the bucket in the environment that can not only shade the spikes of the drifting board, but also allow the sun to shine on the bucket, control the water temperature between 18 -25, and the gardenia can grow more than 3 cm roots in a week. This method cuts gardenias, the survival rate is 100%.

Gardenias prefer a well-ventilated environment with plenty of sunlight, but it is very taboo to be exposed to strong sunlight, and is suitable for planting in loose, fertile, well-drained acidic soils.

Gardenia cultivation method:

Watering. Gardenias prefer moist and moist environments, and during the growing phase from April to September, watering keeps the potting soil moist. Watering gardenias requires seasonality.

Water about 3 days in the spring. In summer, water 1 time a day in the morning or evening. Water about 2 or 3 times a week in autumn.

Control watering in winter, and use warm water when the soil is dry.

Fertilize. When planting and repotting, the soil can add an appropriate amount of cake fertilizer or bone meal as base fertilizer. In the growth period, organic liquid fertilizer can be used for fertilization, and then used after dilution, about once a month.

In spring, flower buds will grow, and fertilization can be done with potassium dihydrogen phosphate fertilizer based on phosphorus and potassium elements, about once a week, which can promote the differentiation of flower buds until the flower buds are formed. No fertilization is applied during flowering, and potassium dihydrogen phosphate can be used once after flowering, which is helpful for later growth.

Soil. The soil can be mixed with 4 parts of peat soil + 1 part perlite + 1 part + 1 part of pine needle soil, the soil is rich in nutrients, strong moisture retention and water retention, soft and breathable, and slightly acidic, which is very suitable as the cultivation soil for gardenias.

Illumination. Gardenia likes light and is a typical strong positive flower, which needs to be exposed to sufficient sunlight in spring, autumn and winter, so that the flowering will be bigger and more fragrant. In summer, the temperature is high and the light intensity is high, so it is necessary to take good shade measures to avoid the leaves turning yellow.

Trim. The main pruning time of gardenias is during the growth period from May to July and the dormant period around December, and there is no need to overprune the two stages. When the growth is relatively vigorous, the branches and leaves that are too long, too dense, and have poor growth can be cut off, which look very messy and affect the growth and ornamentation of the branches and leaves should also be pruned appropriately.

After the buds have grown, the poor buds need to be removed, and the sturdy buds should be retained to ensure the quality of flowering, so that the plants can bloom large and full.

Notes:

1. Do not expose gardenias to direct sunlight for a long time, the leaves will be sunburned. Do not keep it in a dark environment for a long time, so that the leaves cannot photosynthesize to form chlorophyll, and there will be yellow leaves, fallen leaves, etc.

2. Gardenia has poor cold tolerance, and the temperature should be controlled above 10 in winter, and frostbite will occur when the temperature is lower than 5, resulting in yellow leaves and falling.

3. Gardenia likes a slightly acidic soil environment, suitable for watering acidic water, and the use of tap water needs to stand for more than 24 hours or water the plants after exposure to the sun, which can avoid soil alkalinization.

If you want to raise gardenias well, you need to pay special attention to 3 points: acidic soil; Plenty of light and regular pruning and thinning during the growing season. Doing the above three points can avoid the occurrence of yellow leaves, only long leaves without flowering, and some common pests and diseases.

I went back and bought it and tried it, and it worked really well, and a lot of new shoots grew. The key ** is also very affordable, with an average of 6 cents per time.

2. Watering. Watering, watering is also watering acidic water, you can water rainwater, but rainwater is not often, then you can also water fermented rice water. But it is also troublesome for rice water to be fermented.

Then pour citric acid water, this one is the easiest to make, just add some citric acid to the water. Watering multiple times a week, so there is no fix, just keep the soil moist. Of course, it is generally poured 2 times a week thoroughly.

It's not good to water too much, and if you have a lot of water, it's easy to soak the roots.

3. Flower pots and soil.

Flower pots and soil, the best ones with holes at the bottom of the pots are not easy to accumulate water. As for the soil, humus is relatively good, and you can't find it, so it's garden soil or humus. These two are easy to obtain in the park, as long as there are many trees, they are basically available.

However, these soils are prone to compacting, so you need to add some particles.
