5. Fertilizer: Fertilize the plant monthly in spring and summer with a balanced houseplant fertilizer. Reduce frequency during fall and winter.

6. Pruning: Pinch stem ends regularly to encourage compact, branched growth. You can also remove stems that are too long to maintain a bushier shape.

7. Repotting: Repot the Tradescantia Purple Heart in the spring every two to three years to renew the substrate and give more space to the roots.

8. Propagation: This plant is easy to propagate. You can do this by cutting the stems and replanting them in moist potting soil.

9. Cleaning: Dust the leaves regularly with a damp cloth to remove dust and keep the plant healthy.

By following these care tips, you should be able to keep a Tradescantia Purple Heart healthy and thriving inside your home.
