When will the four seasons osmanthus bloom?
As a treasure in the courtyard, Siji osmanthus is favored by gardening enthusiasts for its unique four-season flowering characteristics. This fragrant plant not only has a long flowering period, but also can present a magnificent scene full of trees and flowers due to proper maintenance. Mastering the correct flowering management method can allow the four-season osmanthus to bloom elegant and fragrant in different seasons. Analysis on the flowering rules and maintenance points of Fragrance and time characteristics of Fragrance and Fragrance. The main flowering period of Fragrance is concentrated from March to May every year. At this time, when the temperature rises to 15-25℃, flower bud differentiation and bud formation reach the best state. Special varieties can bloom all year round in suitable environments, but spring is still the best viewing period. Five core maintenance factors 1. Select slightly acidic soil (pH 5.5 -6.5) with good air permeability for basin soil substrate configuration, and prepare the substrate according to the ratio of murus soil: garden soil: river sand =4:4:2. Add 5% bone meal to improve the soil quality when changing pots every 2 years, and use red pottery pots to enhance the drainage effect. 2. Fertilizer application techniques Apply decomposed pig manure (diluted 20 times) combined with potassium dihydrogen phosphate (800 times solution) every month during the growth period. Increase the application of phosphorus and potassium fertilizers during the flower bud differentiation period, and adopt the principle of "applying thin fertilizer frequently" to avoid excessive nitrogen fertilizer leading to excessive growth. 3. Scientific water management maintains soil moisture at 40%-60% in spring and autumn, and sprays in the morning and evening in summer to increase moisture. Adopt the "see dry and wet" watering method to control the frequency of watering in winter. Special note: When the air humidity is lower than 50%, spray water is needed on the leaves. 4. Temperature control strategy Flower bud differentiation requires 25-28℃ for 15 days, and the appropriate temperature for flowering is 18-25℃. Shade is needed if it exceeds 35℃ in summer, and stay above 5℃ for winter. The temperature difference between day and night of 8-10℃ can promote flower bud formation. 5. Key points for styling and trimming cut off the residual flower branches in time after flowers, and retain 2-3 pairs of bud points. Plastic pruning is carried out in March every year to remove cross branches, insect and insect branches. Spray carbendazim after pruning to prevent infection, and use it with wound healing agents for better results.
Through systematic maintenance and management, Sijigui can achieve the ornamental effect of blooming 3-4 times a year. Regularly observing plant conditions and adjusting maintenance plans based on seasonal changes can not only extend a single flowering period to 20-25 days, but also increase flower density and aroma concentration. It is recommended to use a thermohygrometer for environmental monitoring and establish a maintenance log to record growth data.
