The planting methods and techniques of gardenia were as follows: ** 1. Soil Selection ** - gardenia is suitable for acidic soil, with a pH value of 5 - 6. One could choose to use decayed leaf soil, peaty soil, and half of garden soil as cultivation soil, or use sandy loam soil, peaty soil, garden soil, and river sand to prepare soil, and add manure, composts, cake fertilizer, and elemental fertilizer to improve fertility. If the soil is slightly acidic, it is necessary to add Ferrous Sulphate, AluminiumSulphate, etc. to adjust the ratio of acid and base. He could also directly purchase gardenia soil. ** 2. Illumination Requirement ** - It needs sufficient sunlight to grow. It can be maintained in the sun at other times except for the noon in July and August and winter hibernation. In spring and autumn, an average of about 8 hours of light was needed every day. In summer, attention should be paid to sun protection. Sunshade facilities should be established to maintain 45% light transmission rate. In winter, appropriate light should be used to promote photosynthesis to prevent freezing damage. Long-term exposure to the shade would make the branches thin and slender. ** 3. Water Requirement ** - They liked humid environments and had high requirements for moisture. During the growth period, the soil should be kept moist and there should be a certain humidity around it. Water should be watered frequently. In summer, when the environment is dry, in addition to watering, it is necessary to spray water frequently to keep moisture; in winter, the growth is slow, so it is necessary to control the water appropriately. If the plant is not dry, it can not be watered; if the plant grows too vigorously, do not water it at night, and water it in the morning after the sun comes out. In the northern areas where there was an alkali-water environment, tap water could be placed for one day before watering. 3 - 5 days later, a little lemon acid solution could be watered to keep the leaves green. Water-dissolved iron and aluminum sulfuric acid could also be purchased and watered according to the appropriate ratio. ** 4. Temperatures ** - The most suitable temperature for growth was 18 - 22 degrees. It likes warm environments and has poor cold resistance. It can safely pass the winter at 5 - 10 degrees Celsius. If it is below-10 degrees Celsius, there will be frost damage. In spring, it must wait until the temperature is stable (usually in late April) before moving out of the room. ** 5. Method of fertilisation ** - They like fertilizer. When planting, they can add decomposed cake fertilizer into the soil as base fertilizer. During the growing season, cake fertilizer and Ferrous Sulphate were used to make fertilizer water, which was watered once a week. During the growth period, the fertilizer should be applied once every half a month. Diluted compound fertilizer could be used with a little amount of Fe2S4. Phosphorus and potash fertilizer could make the flowers bigger and more beautiful when the flower buds grew out. The fertilizer should be stopped after the temperature dropped in summer and winter. ** 6. Main Points for Trimming ** - In February, the flourishing and withered branches and leaves can be trimmed to reduce nutrient consumption and promote the growth of side branches. Usually, minor repairs could be done to the local branches and leaves and residual flowers to preserve nutrients and maintain the beauty of the shape, but not all of them should be "shaved". The restoration should be combined with the change in temperature. The blooming of gardenia flowers grew from the flower buds at the top of the branches, and it must be the stiff branches of the year, so it could not be blindly trimmed to let it grow new branches without blooming. ** 7. Slow down the seedlings and change the pots ** - The gardenia that had just been bought home should be slowly planted. Put it in a cool place with scattered light. Do not apply fertilizer or expose it to the sun. When the leaves are not yellow and new buds begin to grow, you can change the pot. ** 8. Other precautions ** - If it is planted on the ground, the distance between the plants should be considered. If it is cultivated as a cut flower or in a large-scale planting place, the distance should be widened as much as possible, and it should be planted during the dormant period. During the growth period, the roots should carry soil balls. The gardenia planted in the open air had strong growth ability and adaptability. The management could be relaxed slightly. It could be planted in a sunny place to avoid exposure to the sun and ensure acidic soil. The novel "Smelling the Jasmine Fragrance Again" is equally exciting.
