Osmanthus trees are a very popular ornamental plant. Their flowers are rich and beautiful. If you want to grow osmanthus trees in your garden or indoors, then cuttage propagation is a very good choice. In this article, we will discuss the methods and precautions for cuttage propagation of osmanthus trees.
1. Preparations Cuttage of osmanthus trees requires some preparation work, including preparing suitable cuttage tools, cultivating soil and handling the mother tree. We need to choose sharp scissors or blades and disinfect them with alcohol to avoid infection with bacteria. Next, prepare culture soil with good ventilation and drainage to ensure that its pH value is appropriate. When processing the mother tree, we need to choose healthy branches for cuttage.
2. Select branches When selecting branches, we should choose young, healthy and disease-free branches for cuttage. This can ensure the growth and development of new roots and improve the survival rate of cuttage. When selecting branches, we need to pay attention to their diameter and length. The diameter is required to be between 0.5 and 1cm, and the length should not be too long. It is generally controlled between 10 and 15cm.
3. Processing branches After selecting the branches, we need to process them. Cut the top into a bevel to avoid water loss during the cuttage process. Cut the bottom to a 45-degree angle and remove the leaves and bud eyes at the bottom to facilitate rooting.
4. Soaking treatment Soaking treatment is a very critical step in the cuttage propagation process of osmanthus trees. Soak the treated branches in light salt water for 30 minutes to eliminate bacteria and viruses in the wound and improve the survival rate.
5. Insert the culture soil Next, insert the processed branches into the culture soil. The insertion angle should be at a 45-degree angle to the culture soil to ensure that the branches are not prone to rot. The distance between each cutting hole should be controlled between 10 and 15cm.
6. Moisture retention After inserting the culture soil, we need to maintain the humidity of the culture soil. You can use a spray can to spray water above the branches, or you can cover the surface of the culture soil with a layer of moist gauze to increase humidity.
7. Avoid direct sunlight During the cuttage process, we need to place it in a place that avoids direct sunlight. Strong sunlight will cause water to evaporate too quickly and affect the survival rate of cuttage.
8. Gradually adapt to the outdoor environment When the cuttage seedlings grow to 5 to 6 leaves, they can gradually adapt to the outdoor environment. Keep it in a semi-shaded place to avoid sun exposure. Gradually increase the time and intensity of its exposure to sunlight.
9. Control the temperature During the cuttage process, attention should be paid to controlling the temperature. Too high a temperature can easily cause water to evaporate too quickly, and too low a temperature can lead to slow growth. Generally speaking, 20~30℃ is the optimal growth temperature.
10. Fertilization Cutting seedlings need appropriate amounts of fertilization during the growth process. You can use diluted compound fertilizer to fertilize once every 2 weeks.
11. Weeding and loosening Cutting seedlings need to be weeded and loosened during their growth process. Weeding prevents weeds from competing for water and nutrients, and loosening the soil can increase the breathability of the soil.
12. Pruning cutting seedlings need to be pruned when they grow to a certain height. Generally speaking, pruning can be carried out from March to April every year to maintain the shape and body shape of the seedlings.
13. Pay attention to the control of pests and diseases During the cuttage process of osmanthus trees, we need to pay attention to the control of pests and diseases. If pests and diseases are found, timely measures must be taken to treat them to avoid spread.
14. After waiting for the cuttings to survive, we need to wait for a while to see the results. During this period, we need to wait patiently, while paying attention to the care and management of cuttage seedlings.
15. Many matters need to be paid attention to in cuttage propagation of osmanthus trees, including branch processing, soaking treatment, moisturizing, etc. Only by paying attention to these issues can we improve the survival rate of cuttage and make the cuttage process smoother. I hope this article can help everyone and help you successfully plant beautiful osmanthus trees.
