Keep the soil consistently moist but not waterlogged. Water thoroughly when the top centimeter of soil begins to feel dry. Avoid letting the plant sit in standing water, as this can lead to root rot.

Reduce watering slightly during cooler months, but do not allow the soil to dry out completely.

Pinch back the growing tips of young plants to encourage bushier growth and more blooms. Remove spent flowers regularly to prolong the blooming period and prevent the plant from putting energy into seed production.

Light pruning can also be done to maintain shape.

Exacum appendiculatum is typically propagated from seeds sown in spring or early summer. Sow seeds on the surface of a well-draining seed-starting mix and keep them consistently moist and warm.

Germination can take several weeks. Cuttings are less common but possible.

Repot your Exacum appendiculatum every 1-2 years in spring, or when it becomes root-bound. Use a well-draining potting mix, such as a blend of peat moss, perlite, and compost.

Choose a pot that is only slightly larger than the current one to avoid overwatering issues.
