How much water does gardenia pour?
Among the many aromatic plants, gardenia is favored by gardening enthusiasts for its jade-white flowers and refreshing aroma. As a typical wet-loving plant, scientific and reasonable watering methods directly determine the growth status and flowering quality of gardenia. This article will provide you with a comprehensive analysis of the mystery of water management of potted gardenia, from the tips for watering in all seasons to specific operation details. Differences in seasonal watering quantity among the four core elements of gardenia watering. In spring and autumn, regular watering should be maintained every three days, and daily spraying should be used to maintain the air humidity of more than 65%. During the high temperature period in summer, the double watering method is implemented in the morning and dusk, and a "slow-dipping" water supply is used to ensure complete infiltration of the basin soil. During the winter dormant period, the principle of "see dry, see wet" is implemented, and water is replenished at an interval of 2-3 days after the soil surface is whitened. The basin soil infiltration standard adopts the "five-step inspection method" to confirm the penetration of water: 1. Observe the water seepage from the drainage holes in the basin floor 2. There is no dry particles when the bamboo stick is inserted into the basin soil 3. The weight of the flowerpot increases significantly 4. There is no water in the surface soil 5. The outside of the pottery pot returns evenly. Avoid root system floating caused by "half water" and regularly use dipping basin method to replenish deep water. During special periods, the watering amount will be increased by 0.5 times during the bud incubation period, and potassium dihydrogen phosphate solution will be used for nutritional supplements. During the flowering period, the "ring-wall water injection method" is used, and a long-spout pot is used to inject slowly along the wall of the basin to prevent water from impacting the flowers. In the rainy season, a water barrier layer is set up on the bottom of the basin, and ceramsite or broken tiles is used to pad the water 3-5 cm high to prevent root retting. The water quality selection standard for advanced maintenance points preferably uses slightly acidic water with a pH of 5.5-6.5, and rainwater, cold boiled water or tap water that has been left standing for 3 days is preferred. Replace regular watering with 200-fold diluted beer solution or fermented rice washing water every month, which can not only replenish trace elements but also adjust the soil pH. Disease prevention strategies implement "three inspections and three controls" management for common water-related yellow leaf diseases: check the permeability of basin soil and control watering intervals; check root health status and control single water volume; check environmental ventilation and control air humidity. If rotten roots are found, they will be repaired immediately and replaced with soil, disinfected with carbendazim solution and replanted.
Grasping the water demand characteristics of gardenia requires long-term observation and practical accumulation. It is recommended to establish a maintenance log to record each watering time, amount of water and plant response. Through scientific water control combined with reasonable fertilization, and appropriate light control, gardenia will be able to maintain shiny leaves and fragrant flowers that continue to bloom. Remember that high-quality water management is the key to making gardenias full of flowers.
