- Provide humidity if the air in your home is dry, such as misting the plant or using a humidity tray
- Reduce watering in the winter months when plant growth slows
- Avoid letting the plant sit in standing water, as this can lead to root rot.

4. Humidity: Exacum thrives in high humidity levels. Mist the plant regularly or place a humidifier nearby to maintain humidity levels of 50-60%.
5. Soil: Plant Exacum in well-draining, peat-based potting soil. A mix of peat moss, perlite, and vermiculite works well for this plant.
6. Fertilizer: Feed Exacum with a balanced liquid fertilizer diluted to half strength every 4-6 weeks during the growing season (spring and summer).
7. Pruning: Remove dead or yellowing leaves and spent flowers to promote healthy growth and blooming.
By providing these ideal growing conditions, you can ensure that your Exacum plant thrives and produces beautiful blooms.
