How to care for the flowering period of osmanthus flowers
The fragrance of eight laurels fills the city. Every golden autumn season, the fragrant osmanthus always attracts countless people to stop and appreciate it. However, many flower lovers often encounter problems such as short flowering period and early fading of flowers during the maintenance process, which is often closely related to improper flowering period care methods. Mastering the correct flowering management skills can make osmanthus blossom more lasting and have a stronger fragrance. Four major maintenance points for osmanthus flowering period control of osmanthus osmanthus is a typical positive plant and needs to ensure 6-8 hours of direct light every day. During the flower bud differentiation period (June to August), full sunshine should be maintained. Adequate light can promote the flower bud formation rate to more than 80%. When the flower buds show color, it is recommended to move to a semi-shaded environment (30% shading rate). Moderate shading can extend the flowering period of a single flower by 3-5 days. Special attention should be paid to avoid direct strong light at noon, and sunshade nets can be used for protection. Fine water management Keep the soil moisture at 60%-70% during the budding period, and adopt the watering principle of "seeing dry, seeing wet". When entering the full flowering period, the watering frequency should be controlled to maintain the soil water content at about 40%. You can use finger soil exploration method: Insert the second knuckle of the soil and then water it when it is dry. At the same time, it is necessary to avoid spraying water on the leaves to prevent stagnant water and rot in flowers. It is recommended to replenish humidity through tray water supply. Nutritional Science Supply Topdressing potassium dihydrogen phosphate (diluted 1000 times) begins 30 days before flowering, once every 10 days for three consecutive times. Fertilizer should be stopped immediately after the first flower blooms. At this time, fertilization will cause new shoots to grow and compete for flowering nutrients. Special reminder: Organic fertilizer needs to be applied 3 months in advance, and mixing decomposed sheep manure and soil in a ratio of 1:5 has the best effect. Balancing temperature and humidity control to keep the temperature of 18-25℃ during the day and 15-18℃ at night is most conducive to flowering. The temperature difference exceeding 10℃ may easily lead to flower falling. When the temperature exceeds 28 ° C, it should be cooled by sprinkling water on the ground, and the fan should be used to increase air circulation. Humidity control in 60%-70% interval, humidity is too high can be placed around the plant lime moisture absorption. Special techniques to extend flowering in the early flowering bud, can be applied 0.1% borax solution foliar spray, can make flowering extended 7-10 days. Remove the old leaves at the base in time and retain 6-8 new leaves at the top to reduce nutrient consumption. Mechanical damage caused by wind and rain can be effectively prevented through bagging protection (unfastening for 2 hours per day for ventilation).
Mastering these flowering care secrets can turn osmanthus osmanthus from a "flash in the pan" to a "lasting fragrance." Keep in mind the core principles of fertilizing before flowering and controlling water during flowering, and with precise environmental control, your osmanthus flowers will surely fill the branches every year. It is recommended to use pH paper to test the soil pH value every month. Maintaining it between 5.5 and 6.5 is most conducive to nutrient absorption.
