Osmanthus belongs to the Osmanthus genus of the Oleaceae family, which is a evergreen tree or shrub and one of the traditional top ten famous flowers in China. Depending on the color of the flowers, there are golden osmanthus, silver osmanthus, and red osmanthus; by blooming period, there are August osmanthus, four-season osmanthus, and monthly osmanthus, etc. Osmanthus is one of the excellent garden trees in the southwest region that combines greening, beautification, and fragrance for both ornamental and practical purposes. Every year, on the 15th day of the eighth lunar month, the fragrance of osmanthus flowers is pervasive, refreshing, and invigorating.
The best time to plant and transplant osmanthus trees is in the spring before the trees sprout (February to March) and in the fall, around November. For young trees, spring is more suitable to avoid frost. In warmer regions, planting in the fall is better than in spring because osmanthus trees are evergreen. The roots of evergreen trees grow throughout the year. After a winter, the roots heal well, allowing the osmanthus trees to grow vigorously after the start of the spring nutrient period.
What issues should be considered when planting and transplanting osmanthus trees?
1. For potted osmanthus, it is best to use a clay pot with an enlarged drainage hole. Porcelain pots should not be used to plant osmanthus directly and can only be used as outer pots. Generally, one-year-old plants need pots with a diameter of 15-20 centimeters, and three-year-old plants require pots larger than 30 centimeters.
2. When planting and transplanting osmanthus trees, try to keep the soil around the roots, fill in the prepared soil or fertile soil, move the plant, and while arranging the roots, fill the soil, shaking the pot to make the soil adhere to the roots. Fill the soil slightly higher than the root collar. Then water thoroughly and place the pot in a shaded area for about 10 days before moving it to a ventilated and sunny location.
3. If planting directly in the ground, choose a place with sufficient sunlight, fertile soil, deep soil layer, and good looseness and permeability according to the ecological habits of osmanthus trees. Dig a large hole and apply enough base fertilizer. When transplanting and planting, be careful not to damage the roots.
4. After digging the hole, mix the fertilizer and soil evenly, place the osmanthus tree in the center of the planting hole straight, ensure the roots are spread out, fill the soil to half the depth of the hole, then slightly lift and shake the osmanthus plant, tread the soil firmly, and do not plant too deep. Keeping the root collar level with the ground is fine.
5. Watering should follow the principle of "watering when dry and avoiding excessive watering or waterlogging in the pot." This means watering thoroughly when the soil is dry, waiting for it to dry before watering again, and not watering when it's not dry. Do not water in the scorching sun. Avoid watering during rainy days and be sure to drain the excess water after rain to prevent waterlogging in the pot, as积水 in the soil can cause root rot.
