How to propagate an Osmanthus fragrans tree through cutting to ensure its survival

Main content introduction: This article provides knowledge on how to propagate an Osmanthus fragrans tree through cutting to ensure its survival and the flowering months for growing Osmanthus. Detailed introduction is provided below.

Osmanthus fragrans, also known as sweet osmanthus, is an evergreen shrub or small tree famous for its strong floral fragrance. Not only is it an ornamental plant, but its flowers can also be used to make osmanthus tea, osmanthus wine, and other food items, holding high economic value. Cutting is a common method of propagation for the Osmanthus fragrans tree, allowing for the quick acquisition of a large number of seedlings. Below, we will introduce in detail the method for cutting Osmanthus fragrans trees and the flowering times of the plant.

Methods to ensure the survival of Osmanthus fragrans cuttings

1. Choosing the right time for cutting

The cutting time for Osmanthus fragrans trees is generally in spring or autumn when the climatic conditions are suitable for their growth. Spring cuttings usually occur from March to May, while autumn cuttings are from September to November. Although spring cuttings have a higher survival rate, autumn cuttings result in faster growth of the seedlings.

2. Preparing cutting materials Cutting selection: Choose healthy, pest-free one-year-old or two-year-old branches as cuttings. The length of the cuttings is usually 10-15 centimeters, with 2-3 nodes. Tool preparation: Prepare sharp scissors or a blade for cutting the cuttings; prepare rooting powder or rooting solution to promote root growth.3. Processing cuttings Cutting the cuttings: In the morning or evening, cut branches with plump buds as cuttings. When cutting, ensure the cut surface is smooth to reduce water evaporation. Treating the cut surface: Cut the lower end of the cutting at a 45-degree angle to increase the water absorption area. At the same time, make a straight cut at the upper end of the cutting to reduce water evaporation. Applying rooting powder: Apply an appropriate amount of rooting powder to the lower end of the cutting or soak it in a rooting solution to promote rooting.4. Preparing the cutting substrate

The cutting substrate should be loose, breathable, and have good drainage. Common substrates include river sand, vermiculite, and perlite. Thoroughly water the substrate and keep it moist.

5. Cutting operation Inserting the cutting: Insert the processed cutting into the substrate, with a depth of about 1/3 to 1/2 of the cutting's length. Firming the substrate: Gently firm the substrate around the cutting to ensure a tight bond with the substrate.6. Management after cutting Shading: After cutting, to avoid direct sunlight, set up a shading net or place it in a semi-shaded area. Moisturizing: Keep the substrate moist but avoid waterlogging. Use spraying to maintain the humidity of the air. Temperature control: The temperature after cutting should be kept between 20-25 degrees Celsius, as too high or too low temperatures will affect rooting. Fertilizing: About a month after cutting, when the cuttings start to root, apply a light fertilizer to promote seedling growth.7. Transplanting

When the cuttings have rooted and new leaves have grown, they can be transplanted. During transplantation, protect the new roots as much as possible to avoid damage.

Flowering time of Osmanthus fragrans

The flowering time of Osmanthus fragrans varies by variety and climatic conditions. Generally, the blooming period is from September to October each year, which is the peak flowering season for osmanthus. Some varieties, like the everblooming osmanthus, can bloom at different times of the year, but the main flowering period is still in autumn.

Golden osmanthus: Flowers from September to October with golden yellow flowers. Silver osmanthus: Flowers from September to October with silver white flowers. Red osmanthus: Flowers from October to November with orange red flowers. Everblooming osmanthus: Flowers at irregular times, can bloom multiple times a year with white or light yellow flowers.

Conclusion

Through the aforementioned cutting method, one can effectively propagate Osmanthus fragrans trees. During the cutting process, attention should be paid to choosing the right time, processing the cuttings, preparing a suitable substrate, and post-cutting management. Additionally, understanding the flowering time of osmanthus can help us better appreciate and utilize the plant. We hope this article can help friends interested in propagating Osmanthus fragrans trees.
