Maintenance for Tibouchina semidecandra, or the Princess Flower, involves a few key practices to ensure its health and optimal blooming:

1. Pruning:
   • Regular pruning helps maintain a desired shape and encourages bushier growth.
   • Prune after the flowering season to shape the plant and remove any dead or damaged branches.
2. Watering:
   • Provide regular watering, especially during dry periods, to keep the soil consistently moist but not waterlogged.
   • Adjust watering frequency based on weather conditions and the specific needs of the plant.
3. Fertilization:
   • Feed with a balanced, slow-release fertilizer during the growing season to promote healthy foliage and abundant flowering.
   • Follow the recommended dosage on the fertilizer packaging and avoid over-fertilizing.
4. Soil:
   • Ensure well-draining soil to prevent waterlogging, which can lead to root rot.
   • Consider adding organic matter to improve soil structure.
5. Sunlight:
   • Plant in a sunny location to encourage vigorous growth and prolific blooming.
   • Princess Flower thrives in full sun but can tolerate partial shade.
6. Pest and Disease Control:
   • Monitor for common pests like aphids and whiteflies, and treat promptly if detected.
   • Keep the area around the plant clean to reduce the risk of diseases.
7. Winter Care (for cooler climates):
   • In cooler climates where temperatures may drop significantly, provide protection during winter, such as covering the plant or moving it indoors.
8. Mulching:
   • Apply a layer of mulch around the base of the plant to help retain moisture, regulate soil temperature, and reduce weed competition.
9. Support for Tall Varieties:
   • If growing a taller variety, consider providing support to prevent the plant from becoming top-heavy and potentially tipping over during windy conditions.

By incorporating these maintenance practices, you can ensure the health and vitality of Tibouchina semidecandra, allowing it to thrive and showcase its vibrant blooms in your garden.
