Care Guide
Watering

Fertilization
Apply a balanced liquid fertilizer diluted to half strength.. Regular feeding is essential for lush, colorful leaves.
Coffee Grounds Tea：Steep used coffee grounds in water overnight, strain, and use the liquid to water the plant. Provides a gentle nitrogen boost for lush foliage. Avoid applying thick layers of raw grounds directly to soil to prevent mold.Pruning
- Pinch off flower spikes as soon as they appear to direct the plant's energy back into foliage production;
- Regularly pinch back the growing tips of stems to encourage branching and a bushier, more compact habit;
- Remove any dead or damaged leaves to maintain appearance and prevent disease.
