2. water. Osmanthus fragrans is suitable for growing in humid environment. Because the soil planted underground has high water content, it only needs to be watered every 5-7 days in the maintenance process to keep the soil moist. Note that in the rainy season, osmanthus fragrans should be drained in time to prevent plant roots from rotting.
3. Fertilize. In the maintenance process of osmanthus trees, nitrogen fertilizer should be applied every 30 days in spring, summer and autumn, supplemented by phosphorus and potassium fertilizer, so that the branches and leaves of the plants grow more densely. Be careful not to apply high nitrogen fertilizer to osmanthus trees in summer, otherwise the branches and leaves of the plants will grow white.
Step 4 trim. Osmanthus fragrans grows vigorously with dense branches and leaves. In the process of maintenance, the residual branches, diseased branches, dead branches, long branches and dense branches on plants should be cut off in spring and autumn to improve the aesthetics of osmanthus trees.
