When is the best time to plant osmanthus trees for them to survive?
Today, the editor introduces the best time to plant osmanthus trees and some topics about the pruning techniques of osmanthus trees. Let's take a look together!
Osmanthus belongs to the Oleaceae family, Osmanthus genus, evergreen trees or shrubs, and is 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 species in the southwest region that combines greening, beautifying, and scenting. Every year, on the 15th day of the eighth lunar month, the fragrance of osmanthus flowers is pervasive, refreshing the mind and spirit.
The most suitable time for planting and transplanting osmanthus trees is before the spring sprouting (in February to March) and around November in autumn. Generally, it is better to plant young trees in spring to avoid frost. In warmer regions, planting in autumn is better than in spring because osmanthus trees are evergreen species. The roots of evergreen trees grow all year round, and 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 clay pots with appropriately enlarged drainage holes. Porcelain pots cannot be used to plant osmanthus directly and can only be used as outer pots. Generally, one-year-old plants require a pot with a diameter of 15-20 centimeters, and three-year-old plants need a large pot of over 30 centimeters.
2. When planting and transplanting osmanthus, try to keep the plants with soil, fill in the prepared culture soil or fertile soil, then move the plant, arranging the roots while filling the soil, continuously shaking the pot to make the soil adhere closely to the roots, filling the soil slightly higher than the rootstock. Then water thoroughly and place the pot in a shaded area for about 10 days before moving it to a ventilated and sunny place.
3. If planting in the ground, choose a place with sufficient sunlight, fertile soil, deep soil layer, and good loose permeability according to the ecological habits of osmanthus. 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 of the hole, then slightly lift and shake the plant, tread the soil down, and do not plant too deep, keeping the rootstock level with the ground.
5. Watering should follow the principle of "water when dry and stop when wet," avoiding excessive watering and waterlogging in the pot. Water thoroughly when the soil is dry, and wait for it to dry before watering again. Do not water under the scorching sun. Do not water during rainy days and make sure to pour out the excess water after rain to prevent waterlogging in the pot, as waterlogged soil can cause root rot.
