This article will provide an in-depth analysis of the flowering cycle of osmanthus osmanthus and share professional flowering management skills to help you extend this autumn day and limit fragrance. Analysis of the length of flowering period of osmanthus osmanthus flowers. Conventional flowering cycle Most osmanthus varieties bloom from September to October, and a single flowering period usually lasts for 20-30 days. As a special variety, Sijigui has the characteristics of blooming in all seasons, but the main flowering period is still the most prosperous in autumn, and the aroma of flowers in winter and spring turns significantly weaker. Key factors for flower falling The actual flower falling time is affected by three major factors: ① The temperature difference between day and night is best controlled at 8-12℃; ② The air humidity is maintained at 60%-70%; ③ The drainage performance of the cultivation substrate. Meeting these conditions can extend the flowering period to about 40 days. Fine management of sweet-scented osmanthus flowering period, light control plan needs to ensure that light is scattered for 4 hours per day during the bud period, and the buds are transferred to a semi-shaded environment after being transparent. Pay special attention to avoid direct strong light at noon, and use sunshade nets to filter 30% of the light intensity. Scientific water and fertilizer management Apply phosphorus and potassium fertilizers (N:P:K=1:3:2) during the flower bud differentiation period (early August), and top dressing once every 15 days. After buds appear, 0.2% potassium dihydrogen phosphate will be sprayed on the leaves, and fertilizer application will be stopped at flowering. Keep watering dry and wet, and pour thoroughly when 3cm of topsoil is dry. Microenvironment is created by setting up water trays around the plants to increase humidity, and combining morning and evening spraying to maintain humidity in the small environment. Build temporary insulation sheds when the temperature drops sharply and maintain the night temperature at no lower than 15℃ can effectively delay the falling of flowers.
By implementing a three-stage management method of promoting flower nutrient reserves before flowering, regulating environment during flowering, and timely pruning in late flowering, and cooperating with variety selection (Dangui series recommended), the ornamental period of osmanthus can be maximized. Mastering these professional skills will allow the "Golden Seed Fairy" in the courtyard to bloom with a more lasting fragrance and charm.
