How to cultivate osmanthus saplings
Osmanthus is one of China's traditional famous flowers and is loved for its rich fragrance and long flowering period. Cultivating osmanthus saplings requires mastering scientific methods. From seed selection, soil preparation to daily management, every step is crucial. Below is a detailed cultivation guide to help you successfully grow Osmanthus saplings.
1. Selection and purchase of sweet-scented osmanthus saplings
Choosing healthy osmanthus saplings is the first step to successful cultivation. The following are things to consider when purchasing sweet-scented osmanthus saplings:
| Project | request |
|---|---|
| Variety | Choose varieties suitable for your local climate, such as golden osmanthus, silver osmanthus, or four-season osmanthus. |
| Seedling age | It is recommended to choose strong seedlings that are 1-2 years old, have developed root systems, and are free from diseases and insect pests. |
| branches and leaves | The leaves are plump and bright green in color, with no yellowing or spots. |
| root system | The root system is intact with no rot or damage. |
2. Soil preparation and planting
Osmanthus prefers loose, fertile, well-drained, slightly acidic soil. Here are the key points of soil preparation:
| steps | Operation |
|---|---|
| soil selection | Mix humus soil, sand soil and garden soil in a ratio of 3:1:1. |
| pH adjustment | The soil pH should be maintained between 5.5-6.5 and can be adjusted by adding sulfur powder. |
| Planting depth | The depth of the dug hole should be 2 times the root system of the sapling, and the width should be 1.5 times. |
| fertilize | Apply decomposed organic fertilizer (such as chicken manure or compost) to the bottom of the pit and mix it with the soil. |
3. Daily management and maintenance
Daily management of Osmanthus saplings includes watering, fertilizing, pruning and pest and disease control. The following are the specific operations:
| Manage projects | Operational points |
|---|---|
| watering | Keep the soil moist but not waterlogged. Water once a day in summer and less frequently in winter. |
| fertilize | Apply compound fertilizer once a month during the growth period, and add phosphorus and potassium fertilizer before the flowering period. |
| pruning | Prune dead and diseased branches in spring to promote the growth of new branches; prune lightly in autumn for shaping. |
| Pest and disease control | Common diseases include leaf spot, which can be sprayed with carbendazim; insect pests such as aphids, which can be controlled with imidacloprid. |
4. Propagation method of Osmanthus saplings
In addition to purchasing saplings, you can also propagate sweet-scented osmanthus through cuttings, layering or sowing. The following are the steps for propagation by cuttings:
| steps | Operation |
|---|---|
| Select cuttings | Choose healthy branches that are semi-lignified, 10-15 cm in length, and retain 2-3 leaves. |
| Handling cuttings | Cut the base obliquely and dip it in rooting powder to improve the survival rate. |
| Cutting substrate | Use river sand or perlite and keep it moist. |
| maintenance | Place in a cool and ventilated place and transplant after taking root in about 1-2 months. |
5. Frequently Asked Questions and Solutions
In the process of cultivating Osmanthus saplings, you may encounter some problems. The following are common problems and solutions:
| question | Reason | Solution |
|---|---|---|
| Leaves turn yellow | Soil is too alkaline or lacks water | Adjust soil pH and increase watering frequency. |
| No flowers | Insufficient light or improper fertilization | Ensure more than 6 hours of light every day, and apply more phosphorus and potassium fertilizer before the flowering period. |
| pests and diseases | Ambient humidity is too high or ventilation is poor | Improve ventilation conditions and spray fungicides regularly. |
Conclusion
Cultivating Osmanthus saplings requires patience and care. From seed selection to daily management, every step is related to the healthy growth of the saplings. Through scientific cultivation methods, you can successfully plant fragrant osmanthus trees at home or in your yard and enjoy the natural beauty they bring.
