How to raise gardenias in the north, how to raise gardenias in the north

Hello! <>

Gardenia cultivation method:

1. 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.

2. Fertilization. When planting and repotting, an appropriate amount of cake fertilizer or bone meal can be added to the soil 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.

3. Soil. The soil can be mixed with 4 parts of peat soil + 1 part of 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.

4. 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.

5. Pruning. 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 plant has buds, it is necessary to remove the buds that are not growing well, and keep the strong buds to ensure the quality of flowering, so that the plants can bloom large and full.

Gardenias prefer an acidic environment, so the soil must be acidic and avoid alkaline. The cultivated loam soil can be mixed with humus, vegetable garden soil, humus soil, and river sand in a ratio of 4:4:1:1, but it must be guaranteed to have good air permeability and water permeability.

Its optimal growth and development temperature is between 20 and 25, and it can tolerate low temperatures of -3, but it should not be left for a long time, otherwise it will cause frostbite. When the temperature is higher than 15, the window should be opened in time to ventilate and relieve the heat, so as to facilitate its subsequent growth and flowering.

Its growth environment is generally very bright, especially in spring and autumn, and it must be ensured that it can receive at least 8 hours of sunshine every day, otherwise it will be extremely unfavorable for its future wintering and growth. However, in the hot summer, to avoid strong light exposure, it is best to store it in a place of astigmatism and then transfer it to direct sunlight after winter.

It does not like fertilizer, but it also needs to be supplemented with fertilizer regularly, the day before the fertilizer is applied, the watering should be stopped, and the rotten fertilizer can be applied once in about ten days, and then watered again after the fertilizer, and the fertilizer will basically stop in the middle of September.

Spring and autumn are relatively dry, so you can water once every three days, and in summer, you should water after the temperature drops, about two o'clock in the afternoon. In winter, watering should be controlled and watering when the potting soil is dry.

<> gardenia needs to pay attention to the control of light, temperature, water and fertilizer and regular soil change when maintaining gardenia in the north. The temperature of the growing environment of the plant should be stable between 18-22 degrees Celsius, give it sufficient scattered light irradiation, avoid exposure to the sun, watering the first dry and wet, apply thin fertilizer frequently, and replace the new soil regularly.

1. Stable temperature.

The most important thing in cultivating gardenias in the north is to stabilize the temperature of the growing environment. Gardenia is a plant that prefers to live in a warmer environment and is not very resistant to cold, so it is necessary to stabilize the temperature of the environment where the plant is located between 18 and 22 degrees Celsius in the north where the temperature is lower.

2. Light control.

When maintaining gardenias, it should be noted that the plant needs more sufficient light for photosynthesis, but at the same time prefers a semi-shaded environment, so it is enough to give a certain period of scattered light irradiation, and carry out shading maintenance when the sun is more intense to avoid the plant receiving too strong light exposure.

3. Control water and fertilizer.

The air in the north is relatively dry, and the water in the soil evaporates relatively quickly, so when watering the plants, it is necessary to adjust according to the actual situation of the soil to ensure that the soil is in a slightly moist state for a long time.

4. Regularly change the soil.

Regularly changing the soil for the plants is also one of the important steps in the maintenance of the northern junzi orchid. After a long time of watering and fertilization, the soil will appear compacted, rigid or salinized and other abnormal phenomena, which need to be turned and replaced in time, about once every 1-2 years, to ensure that the growth environment of the plant is comfortable enough.

Gardenia how to raise in the north, gardenia is evergreen all year round, white flower color, dense flowers, overflowing flower fragrance, is a better plant for potted ornamentation.

Gardenias like warm and humid climates, like wet and dry, humidity in 40 70, can grow. Potted plants such as 7 to 10 days without watering will die of drought. It is required to have well-drained, fertile and loose acidic soil, and it is advisable to control the soil pH value of 4 0.

Resistant to pruning, resistant to moisture, sensitive to low temperature reactions at the seedling stage. In summer, if strong light, high temperature, and heavy rain do not improve the environment, it may induce yellow leaves, resulting in their gradual death. The optimal growth temperature for gardenias is 16 to 18.

Low temperature and direct sunlight are extremely unfavorable for its growth, so it is advisable to maintain gardenias in a well-ventilated, humid and transparent environment 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.

The biggest problem of gardenia cultivation in the north is the alkalinization of the soil, one is to change the pot every year, and the other is to apply ferrous sulfate to prevent soil alkalinization. Gardenia is a typical acid-loving plant, and when the soil becomes alkaline, it will have yellowing of leaves and a large amount of defoliation. The solution is to use acidic fertilizers whenever possible, or to apply ferrous sulphate, which can be sprayed on the foliar surface with an aqueous solution of ferrous sulphate.

If ferrous sulfate is not available, it can also be diluted 200 times with vinegar and sprayed on the leaves or irrigated roots. Gardenia buds may fall due to the following reasons: first, the air humidity is low; second, the potting soil is wet, causing root rot of plants; Third, there is a small amount of harmful gases mixed in the air; Fourth, if it is a newly purchased gardenia, it is not excluded that the temperature or moisture and light during transportation are not suitable, and the above is an introduction to how to raise gardenias in the north.

Gardenia in the north needs to be exposed to sufficient scattered light, and temperature control measures should be taken in summer and winter to avoid it growing in a too cold or too hot environment. It needs a moist environment every day, and it needs to be thinly fertilized during the growing season. It also needs to be replaced with new potting soil every 1-2 years so that it can grow vigorously.

Chiropractic. 1. Light and temperature conditions

Breeding gardenias in the north, it is best to put it in a semi-shaded environment to ensure that it has sufficient scattered light exposure is the best, pay attention to the summer must do a good job of shading measures to avoid it being exposed to strong light, gardenias like warmth, so in the summer and winter of the north, it is also necessary to do a good job of temperature control measures for it, to avoid it growing in a too cold or too hot environment.

2. Reasonable water and fertilizer

Gardenia breeding in the north, but also need to apply water and fertilizer reasonably, daily need to keep the potting soil slightly moist, but can not produce water in the sedan car, air humidity needs to be more than 70%. During its growth period, it needs to be applied to it every half a month, and it should be stopped in winter to avoid fertilizer damage.

3. Regularly change soil

Gardenia has high requirements for soil, and is most suitable for growing in loose, fertile and well-drained weakly acidic soil, so when breeding in the north, it also needs to be changed regularly, generally every 1-2 years, so as to avoid soil compaction or change in nature.
