Water regularly to keep the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings, especially during warmer months.

Reduce watering in winter when the plant's growth slows down. Good drainage is crucial to prevent root rot.

Pinch back the growing tips regularly to encourage bushier growth and more flowers. Remove spent flowers (deadheading) to prolong blooming. Light pruning can be done after flowering to maintain shape and size.

Heavy pruning is generally not needed.

Easily propagated from seed sown in spring, or from stem cuttings taken in late spring or early summer. Seeds germinate best with gentle warmth and consistent moisture.

Cuttings root readily in moist potting mix, often within a few weeks.

Repot your Isotoma axillaris every 1-2 years, or when it becomes root-bound. Choose a pot that is only slightly larger than the current one. Spring is the ideal time for repotting, just as new growth begins.

Use a well-draining potting mix.
