How to raise gardenia
As a typical representative of evergreen shrubs, gardenia is favored by horticulture enthusiasts for its white and fragrant flowers and evergreen leaves. However, many flower lovers often encounter problems such as poor growth and falling leaves in winter during actual maintenance. This paper will systematically analyze the key points of scientific maintenance of gardenia and provide professional solutions to the difficulties of winter maintenance. Four elements of gardenia core maintenance acidic soil configuration skills Gardenia is extremely sensitive to soil pH, and the pH value needs to be strictly controlled between 5.0 and 6.0. It is recommended to use a mixed substrate with humus soil: peat soil: river sand =4:3:3, and use ferrous sulfate solution to adjust the pH value every quarter. Pay special attention to the alkaline water and soil in the northern region, and citric acid aqueous solution needs to be replenished every month to maintain an acidic environment. Light, warm water and fertilizer are accurately controlled in spring and autumn to ensure scattered light for 6 hours a day. In summer, 50% sunshade nets need to be erected to avoid leaf burns. Adopt the "see dry and wet" watering method, and cooperate with ceramsite backing to enhance drainage. During the growth period, use decomposed cake fertilizer water and potassium dihydrogen phosphate alternately every 15 days, pay attention to the principle of thin fertilizer and frequent application, and stop fertilization in winter. Key points for winter management of gardenia are evergreen characteristics and abnormal deciduous leaves. As an evergreen plant, gardenia should keep its leaves green in winter under normal conditions. If falling leaves occur, it is mostly caused by a sudden drop in temperature (below 5℃), excessive humidity of the basin soil, or drying of the heating room. It can be improved through comprehensive measures such as bagging for insulation, controlled watering and foliar spraying. Optimization plan for wintering environment in northern regions, it is recommended to enter the house for maintenance and maintain the optimal wintering temperature of 8-15℃. Ventilate twice a week for 1 hour each time, while using a humidifier to maintain 60% air humidity. Wipe the leaves regularly with a damp cloth to clean and remove dust and promote photosynthesis.
Through the establishment of a scientific maintenance system, gardenia can not only survive the winter safely, but also achieve anniversary viewing. Mastering key technologies such as soil improvement and environmental control, even novices can keep gardenia evergreen and blooming all year round.
