The website introduces how to plant osmanthus seeds and the key points of osmanthus cultivation techniques, and then takes everyone to understand together.
Osmanthus trees are common ornamental flowering trees or shrubs, with a height of about 3-5 meters, a full crown, and dense branches. Osmanthus trees are currently widely used as landscaping trees, preferring a warm and humid environment, relatively cold-resistant, and fond of sunlight. Raising osmanthus trees requires proper water and fertilizer management, pruning, and pest control. There are three propagation techniques for osmanthus trees: seeding, cutting, and layering. We can choose any method to raise seedlings. The young seedlings of osmanthus trees have poor resistance and require careful care, strengthening water and fertilizer management to make the seedlings gradually grow taller, stronger, and capable of flowering. After that, you can enjoy the osmanthus flowers every year.
1. Seeding
Prepare osmanthus seeds in advance, choosing seeds that are full and plump to ensure survival rates. Osmanthus seeds are suitable for spring or autumn sowing. Adjust the land first, and place the seeds with the hilum on the side during sowing to avoid bending the radicle and young shoot. After sowing, cover the surface with a layer of fine sand, then cover it with straw matting, water to keep it moist, and the seedlings will emerge after a few days.
2. Cutting
Osmanthus tree cutting should be done before spring germination, using one-year-old healthy branches as cuttings, with a length of 5-10 centimeters, removing the lower leaves and leaving 2-3 leaves on top. Use special nutrient soil as the cutting medium, and maintain a temperature of 20-25℃ after cutting. The cuttings will root in about two months.
3. Layering
Osmanthus trees are layered in spring or early summer, and the survival rate is also relatively high. Choose a relatively thick and low trunk mother tree, select healthy branches that are 1-2 years old, choose a flexible part, cut the branch to the xylem with a sharp knife, then press it into the soil 3-5 centimeters deep, keep the soil moist, and when the branches take root in autumn, you can cut off the branches and then transplant them.
4. Soil
Soil that is fertile and has good drainage is suitable for osmanthus tree growth. When planting osmanthus trees, mix sand, cake fertilizer, garden soil, and decomposed leaf soil in a ratio of 3:2:3:2. This type of soil is both fertile and breathable, allowing osmanthus trees to grow healthily.
5. Sunlight
Osmanthus trees require plenty of sunlight, especially before flowering. We should place the osmanthus trees in a fully sunlit environment. In the summer, when sunlight is too strong, it can be appropriately shaded to prevent sunburn to the osmanthus trees.
6. Water
Any plant cannot do without the nourishment of water. Osmanthus trees prefer a humid environment and should be watered promptly during the growing period. Also, avoid watering too frequently; water when the potting soil is completely dry, and do not water when the soil is moist.
7. Fertilization
Apply some phosphorus and potassium fertilizers to osmanthus trees before and after flowering, once every half month, which helps flowering and makes the osmanthus trees flourish. During the growing period of young osmanthus seedlings, you can apply some nitrogen fertilizer, but the amount should not be too much.
8. Pruning
Proper pruning is beneficial for the growth of osmanthus trees and improves their overall aesthetics. When pruning, mainly cut off the wilted and withered branches on the osmanthus trees, as well as the long and overlapping branches, to increase the ventilation and light penetration of the tree.
The above is a specific introduction to how to plant osmanthus seeds and the key points of osmanthus cultivation techniques, hoping to bring some flower knowledge to green plant enthusiasts.
