How to water osmanthus during flowering period
In the golden autumn season, osmanthus fragrance is fragrant, and mastering flowering maintenance techniques directly affects the flowering quality. As one of the top ten famous traditional flowers in China, the flowering management of osmanthus needs to focus on the three major elements of water regulation, light regulation and nutrient supply. Scientific maintenance can keep the fragrance of osmanthus fragrant for more than a month. 1. Moisture management during flowering period of osmanthus fragrans 1.1 Water control techniques before flowering. During the flower bud differentiation stage (beginning of autumn to white dew), the substrate is maintained in a slightly moist state. It is recommended to water thoroughly every 3 days, and combine morning and evening leaf spray to increase the air humidity to 60%. Special reminder: Tilt the flower pot immediately after heavy rain to drain out stagnant water. Soaking the roots for more than 6 hours may cause falling leaves. 1.2 No watering at full flowering stage. When the inflorescences are fully unfolded, the principle of "seeing dry, seeing wet" is adopted, and water is replenished until the surface soil turns white (about 2- 3 cm deep dry). Typical misunderstanding warning: Excessive watering at this stage will stimulate the germination of new shoots, causing more than 70% of flower buds to fall off prematurely. 2. Key points for comprehensive maintenance during flowering period 2.1 Light control plan After the color of the buds is developed, it is recommended to use a sunshade net to filter 40% of the direct light. Experimental data show that light-suitable maintenance (about 15000lux) lengthens the flowering period by 5-7 days compared with full-day environment. Pay attention to the condition of the leaves, and immediately adjust the light intensity if curling occurs. 2.2 Scientific fertilization strategy Apply high-phosphorus potassium fertilizer (N-P-K=5-15-10) 30 days before flowering, and irrigate roots once every 15 days. Stop fertilization completely during flowering, and apply decomposed cake fertilizer water (diluted 1:50) in time after the flowers wither to help the plants recover and survive the winter. 2.3 Environmental optimization details Maintaining the temperature difference between day and night of 8-10℃ is conducive to the accumulation of aroma substances, and controlling the temperature at night at 15-18℃ is best. Regular rotation of the flowerpot ensures uniform light reception, and combined with thinning of excessively dense branches to improve ventilation can reduce the chance of disease occurrence by 60%.
Through precise water control, light management and nutrient control, combined with temperature and humidity adjustment, the flowering period of osmanthus can be extended to more than 35 days. It is recommended to establish a maintenance log to record daily temperature, humidity and plant status, and gradually form a personalized flowering management plan, so that full branches of golden osmanthus become a reality every year.
