How to raise the natural fragrance of gardenia

To grow gardenia with a natural fragrance, you can refer to the following maintenance points: ** 1. Soil ** 1. [Soil properties: gardenia is suitable to grow in acidic soil.] You can buy special acidic cultivation soil, or you can mix it yourself. For example, you can mix the rotten leaf soil, sand, and garden soil in a ratio of 5:2:3, or add half of the acidic soil (such as fermented pine needle soil) to the soil. Alkaline soil would hinder the absorption of iron by plants, which would affect the formation of photosynthesis, causing the leaves and branches to dry up and wither. 2. ** Soil breathability and drainage **: The soil should be based on the principle of breathability and drainage. When choosing a pot, you should also choose a pot with good breathability. Don't choose a pot that is too deep or too big, such as a pottery pot. ** 2. Watering ** 1. ** Watering frequency **: Gardenias like moist environments, so they should be watered when they are dry and wet. During the growth period, the soil had to be kept moist for a long time. Generally, when the surface of the soil was dry, it would be watered in time, but the premise was that the soil was suitable for ventilation and water. Watering time should be chosen in the morning to avoid watering at night. 2. ** Special circumstances **: When necessary, spray water on the leaves to keep them moist. After budding, control the water appropriately to prevent budding. ** 3. Fertility ** 1. ** Growing season fertilizer **: During the growing season, use multi-element fertilizer to supplement the roots and plants, which can make the roots and plants grow well. The use of pure nitrogen fertilizer should be avoided. Otherwise, it may lead to no flowering or yellow leaves in the later stage. 2. ** Blossoming fertilizer **: Starting from April, you can apply thin fertilizer every 10 - 15 days, and add appropriate amounts of phosphorous and potash fertilizer in the early flowering stage to make the flowers bloom more fragrant. If you want gardenia flowers to bloom very fragrant, try not to put slow-release fertilizer halfway. You can put sheep dung and bone powder. During the budding stage, the solution of monobium potassium hydrogen orthonate should be applied once or twice, and the fertilizer should be stopped when the temperature is high in summer and low in winter. ** 4. Illumination ** 1. [Illumination Requirement: The gardenia is a strong positive flower. Except for the high temperature period in summer and the hibernation period in winter, it needs to be provided with sufficient direct sunlight at all times.] The sufficient light could allow the leaves to photosynthesize and produce nutrients, which would flow back to the bottom to promote the growth of the roots, allowing the gardenia to quickly grow new branches and bloom. It also helped it emit a natural fragrance. 2. ** Summer Light Treatment **: When the sun is high in the sky in summer and early autumn, it is necessary to provide appropriate shelter to prevent sunburn. ** 5. In terms of temperature ** The best growth temperature of gardenia was 16 - 18 ° C, and the suitable growth temperature was 18 - 22 ° C. It could safely survive the winter at 5 - 10 ° C. When it was below-10 ° C, the plant would freeze. Pay attention to lowering the temperature when it is too high and keeping it warm when it is too low. ** 6. Trimming ** 1. ** Trimming time **: The best trimming season for gardenia is after the flowers bloom in spring. Trimming the weak branches, overgrown branches, and other unhealthy branches and leaves. If they were trimmed in autumn and winter, it might affect the flowering of the next year, because gardenias began to bear buds in February every year. 2. ** Trimming frequency **: After the flowering period, you can only trim it once. If you continue to trim it after that, it will cause it to not bloom. This is because after the new branches gradually grow taller and the branches gradually become tough, the top of the branches will grow flower buds to bloom. If you continue to trim, it will be difficult to grow flower buds after the new side buds grow. ** VII. Pest Control ** 1. ** Common pests and diseases **: Yellow disease, leaf spot disease, and scale insects are more common pests and diseases of gardenia, especially during the summer flowering period. Due to the high temperature and humidity, it is easy to breed pests and diseases. 2. ** Control method **: If you find pests and diseases, you should buy chemicals to kill them in time. At the same time, isolate the infected plants from the healthy plants. ** 8. Changing the basin ** 1. ** Changing pot timing **: The gardenia grows faster. In order to prevent the soil from being hardened, the pot space is too small, and the soil nutrients are insufficient, it is generally necessary to change the pot once every 2 - 3 years. Gardenias were typical tropical plants. It was best to change pots in the summer, not in the winter. 2. ** Conservation after changing pots **: After changing pots, place them in a shady place for a few days, and then put them under the sun. If you don't want to change pots, place a tray under the flower pot. The novel "Smelling the Jasmine Fragrance Again" is equally exciting. Everyone is welcome to click and read it!
