Osmanthus fragrans, also known as cassia, is a traditional precious flower tree in China, loved by people for its unique fragrance and beautiful flowers. Osmanthus cutting propagation is a common method, which is not only easy to operate but also fast in propagation speed and high in survival rate. This article will introduce in detail the method of cutting propagation of Osmanthus, helping you to easily cultivate beautiful cassia trees.
Choose the appropriate cutting timeThe best time for cutting Osmanthus is generally in spring and autumn, as the climate is suitable and there is sufficient sunlight during these two seasons, which is conducive to the rooting and growth of the cutting branches. The specific time can be chosen from March to April or September to October every year.
Select healthy cutting branchesSelecting healthy Osmanthus branches is the key to successful cutting. You should choose branches that are vigorous, free from diseases and pests, about 15-20 cm in length, moderately thick, and preferably semi-woody branches.
Prepare the cutting substrateThe cutting substrate for Osmanthus should be selected with good breathability and strong drainage, such as perlite, vermiculite, river sand, etc. Mix the substrate evenly and control the moisture content between 60%-70%.
Conduct the cutting operation1. Cut the lower end of the branch into a slant, about 2-3 cm in length, to increase the water absorption area.
2. Use a disinfected blade or scissors to make a smooth cut at the lower end of the branch to avoid tearing the branch.
3. Insert the processed branch into the cutting substrate, about 3-5 cm deep, and make sure to keep the branch upright.
4. After insertion, gently compact the substrate to ensure a tight fit between the branch and the substrate.
Post-cutting management1. Watering: After cutting, water thoroughly to keep the substrate moist, and then water every 2-3 days to keep the substrate slightly moist.
2. Shading: In the hot season, shade the cutting seedlings to avoid direct sunlight and reduce water evaporation.
3. Ventilation: Maintain a good ventilation environment to facilitate the growth of the cutting seedlings.
4. Fertilization: After the cutting seedlings have rooted, you can apply a small amount of nitrogen, phosphorus, and potassium compound fertilizer to promote growth.
Precautions1. Disinfect the branches and tools before cutting to prevent infection by pathogens.
2. Handle the branches gently during the cutting process to avoid damage.
3. Pay attention to the growth of the cutting seedlings and deal with diseases and pests in a timely manner.
Osmanthus cutting propagation is a simple and easy method. As long as you master the cutting skills and post-cutting management, you can easily cultivate beautiful cassia trees. I hope the detailed introduction in this article can be helpful to you, and wish you success in planting!
