Keep soil consistently moist but not waterlogged. Water thoroughly when the top centimeter of soil feels dry to the touch. Avoid letting the plant dry out completely, as this can cause wilting and stress.

Reduce watering slightly during cooler months to prevent root rot.

Pinch back young plants to encourage bushier growth. Remove spent flowers regularly to promote more blooms and maintain a tidy appearance.

Light pruning can be done anytime to shape the plant or remove any leggy or damaged stems. Avoid heavy pruning.

Easily propagated from stem cuttings taken in spring or summer. Cuttings should be 5-10 cm long and placed in moist potting mix or water. Roots usually form within a few weeks.

Seed propagation is also possible, sown in spring.

Repot Torenia oblonga annually or when it becomes root-bound, typically in early spring. Choose a pot that is only slightly larger than the current one, with good drainage. Use a well-draining potting mix.

Repotting revitalizes the plant and provides fresh nutrients.
