Osmanthus belongs to the Oleaceae Osmanthus genus, evergreen trees or shrubs, and is one of the traditional top ten famous flowers in China. Depending on the flower color, 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 for both ornamental and practical purposes. Every year on the 15th day of the eighth lunar month, the fragrance of Osmanthus fills the air, refreshing and invigorating. How to propagate the Osmanthus tree?
1. Layering propagation method: Layering propagation is usually carried out from March to June. Select one or two-year-old woody branches about 0.5 centimeters in diameter, make a 1-centimeter-wide annular stripping on the branch section where roots need to grow, thus artificially creating a wound to promote root growth. Then wrap the stripping area with moisture-retaining mountain soil or moss and cover it with plastic film to ensure the soil moisture needed for root growth. Water frequently when it's dry, and it will take about two months to grow roots. When there are enough roots, the plant can be cut from the mother plant and cultivated.
2. Grafting propagation method: Commonly used as rootstocks are small-leaf privet, small wax tree, privet, white wax tree, and flowery cherry. Grafting is done before the bud germination in spring, cleft grafting or cleft side grafting in summer, "T" shape bud grafting or large bud slice grafting in autumn.
3. Cutting propagation: Osmanthus cutting is carried out in summer and autumn, using tender branches for cutting. Select robust semi-woody branches of the current year and cut them into 12-centimeter-long segments, leaving 4-5 leaves at the top, and insert them into clean sand or a cutting bed mixed with yellow clay and yellow sand. After cutting, keep the moisture but do not waterlog, and set up a shed to provide shade to avoid direct sunlight. Keeping the temperature at 25-27 degrees Celsius is conducive to root growth and survival. Absolutely do not use fertilized soil for cutting or completely woody Osmanthus branches, as the survival rate is very low and may not even root.
Clean sand refers to sand that has been washed several times to remove the soil it contains, and it does not contain fertilizer. If it contains fertilizer, it can easily cause the cutting branches or leaves to rot.
4. Seed propagation: In March and April, when the seed coat of Osmanthus seeds gradually changes from green to purple-blue, they can be harvested. They can be sown immediately after collection, or after collection, they can be stacked and washed with water to remove the fruit flesh, dried, and then sand-stored until autumn or spring sowing, with the sand moisture content at 10%. The sowing rate is 25 kilograms per mu. When sowing, the seeds should be placed on their side to prevent the germ from bending.
