How to raise osmanthus trees to grow well
Osmanthus trees are favored by gardening enthusiasts for their rich aroma and evergreen characteristics. In order for osmanthus trees to grow healthily and flourish in flowers and leaves, we need to master scientific and systematic cultivation methods. This article, from soil ratio to flowering management, combined with high-definition real shots, provides you with a detailed explanation of the key points of full-cycle maintenance of osmanthus trees. Soil and substrate management Acidic soil preparation of osmanthus tree roots are most suitable for a slightly acidic environment with a pH value of 5.5-6.5. It is recommended to use a golden ratio of legus soil: garden soil: coarse river sand =4:3:3, and add 10kg of decomposed sheep manure per cubic meter as base fertilizer. Regularly adjust the pH and alkali value with ferrous sulfate solution to maintain soil activity. The timing of soil replacement determines that the soil of potted osmanthus flowers needs to be replaced every 2 years. When white salting appears on the surface layer or the root system penetrates the drainage hole, new soil should be replaced immediately. When changing soil, keep 1/3 of the protective soil, cut off the rotten roots and disinfect it with carbendazim. The intelligent watering plan for precise control of water and fertilizer maintains the principle of "seeing dry and wet" in spring and autumn. It is watered once in the morning and evening in summer, and replenished every 10 days in winter. Adopt the bamboo stick detection method: insert the bamboo stick 5 cm into the soil, and replenish water when it is pulled out and there is no moisture trace. Rain or tap water dried for 2 days is best. Staged fertilization strategy Apply nitrogen fertilizer (urea 1:1000) during the germination period in March, apply potassium dihydrogen phosphate (0.2% solution) during the flower bud differentiation period in July, and spray boron fertilizer before the full flowering period in September. Stop fertilizer in winter to prevent root burning, and organic fertilizers need to be completely decomposed. Light and pruning management Dynamic light adjustment accepts full sunshine in spring and autumn, protects with sunshade net from 10:00 to 15:00 in summer, and moves into a southbound balcony in winter. Jingui varieties require more than 1800 hours of sunshine per year, and Dangui varieties can appropriately reduce the sunshine by 20%. Modeling and pruning techniques Re-prune branches with pests and diseases in March every year, and lightly cut the long branches after flowering. Adopt the "three-pronged and nine tops" shaping method to keep the crown transparent. Apply healing agent to the incision after trimming to prevent bacterial infection. Key points for pest and disease control leaf spot diseases are controlled with 800 times of mancozeb solution, and scale insects are sprayed with 2000 times of thiamethoxam solution. Keep the environment ventilated and spray the back of the leaves with garlic extract every month for prevention.
