Watering, pruning, propagation, and repotting details from plant data
Keep the soil consistently moist but not waterlogged. Water thoroughly when the top centimeter of soil feels dry. Avoid letting the plant sit in standing water, which can lead to root rot.
Reduce watering slightly during cooler months.
Pinch back the tips of stems regularly to encourage bushier growth and more blooms. Remove spent flowers promptly to prevent seed formation and promote continuous flowering.
Light pruning can also be done to maintain the plant's shape.
Propagate Exacum tetragonum from seeds sown in spring or early summer. Seeds require warmth and consistent moisture to germinate. Cuttings can also be taken from healthy stems and rooted in moist potting mix.
Repot annually or biennially in spring, moving the plant to a pot one size larger if root-bound. Use a well-draining potting mix, such as a peat-based blend with added perlite. Ensure the new pot has drainage holes.
