How to plant osmanthus saplings
Osmanthus saplings are garden plants with both ornamental and practical value, and their cultivation process requires mastering scientific planting methods. This article will use the form of illustrations + text to analyze the cultivation points of osmanthus saplings from soil treatment to post-maintenance systems to help horticulture enthusiasts achieve efficient cultivation. Soil substrate optimization plan for the core technology of osmanthus saplings cultivation requires preparation of acidic substrate with pH 5.5-6.5 before planting. It is recommended to use the golden ratio of humus soil (40%)+ river sand (30%)+ garden soil (30%). For alkaline soil areas, ferrous sulfate solution can be applied monthly to adjust the pH to ensure that the roots absorb iron normally. Scientific planting operation procedures Excavate planting holes with a diameter of 50cm and a depth of 30cm, lay 5 cm thick decomposed sheep manure organic fertilizer on the bottom as base fertilizer, mix it with the surface soil and cover it with a 10-cm isolation layer. Keep the soil ball intact during planting, and backfill it in layers after the root system is stretched. Pay attention to the root neck to be 3 cm higher than the surface to prevent water accumulation and root rot. The intelligent water and fertilizer management system implements the "three irrigation and three control" strategy after planting: water needs to be fully irrigated for the first time, water needs to be replenished twice after 7 days, and irrigation three times after new buds sprout. During the growth period, 50g of nitrogen, phosphorus and potassium (15-15-15) compound fertilizer was applied every month, and potassium dihydrogen phosphate foliar fertilizer was added during the flower bud differentiation period. Advanced skills for maintaining osmanthus saplings build a sunshade net in summer to control the light intensity at 20,000 - 30,000 Lux, and wrap the trunk with straw ropes to prevent freezing in winter. Regularly prevent pests and diseases, spray carbendazim every season to control (T-J) diseases, and artificially kill pests such as red spiders.

Through the above systematic cultivation management, combined with the illustrated operating points, the survival rate of osmanthus saplings can reach more than 95%. It is recommended to collect the drawings of this article as a visual operation guide, regularly observe the growth status of the plants, and adjust the maintenance plan in time to cultivate healthy plants with strong fragrance.
