Maintaining a healthy and thriving Cape Jasmine involves a few key practices:

1. Watering: Keep the soil consistently moist but not waterlogged. Water deeply when the top inch of soil feels dry. During periods of hot weather, Cape Jasmine may require more frequent watering.
2. Soil: Cape Jasmine prefers acidic, well-draining soil. Use a rich, organic soil mix with good drainage. Adding organic matter, such as compost, to the soil can improve its fertility and structure.
3. Fertilization: Feed your Cape Jasmine with a balanced, slow-release fertilizer in the spring and again in late summer. Follow the recommended dosage on the fertilizer package. Avoid excessive use of high-nitrogen fertilizers, as this can promote lush foliage at the expense of flowers.
4. Pruning: Regular pruning helps maintain the shape of the shrub, encourages bushier growth, and removes dead or diseased branches. Prune after the blooming period to shape the plant and remove spent flowers.
5. Mulching: Apply a layer of mulch around the base of the plant to help retain soil moisture, suppress weeds, and regulate soil temperature. Organic mulches like bark or compost are ideal.
6. Sunlight: Cape Jasmine thrives in partial to full sunlight. Ensure that the plant receives at least 4-6 hours of sunlight per day. In hot climates, some afternoon shade can be beneficial.
7. Pest and Disease Control: Keep an eye out for common garden pests like aphids and scale insects. Treat infestations promptly with insecticidal soap or neem oil. Also, be vigilant for fungal diseases, especially in humid conditions, and use fungicides as needed.
8. Winter Care: While Cape Jasmine is generally hardy, it may benefit from protection in colder climates. Mulch around the base to insulate the roots, and consider covering the plant during extreme cold spells.

Remember to adapt these maintenance practices based on your specific growing conditions and the unique needs of your Cape Jasmine. Regular observation and care will contribute to a healthy and beautiful shrub.
