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

Reduce watering slightly during cooler, less active growth periods.

Pinch back young plants to encourage bushier growth. Deadhead spent flowers regularly to promote continuous blooming and prevent self-seeding.

Light pruning can be done after flowering to maintain shape and encourage a second flush of blooms.

Easily propagated from seeds sown indoors in late winter or early spring, or directly outdoors after the last frost. Cuttings taken in spring or summer can also be rooted in moist potting mix or water.

Repot young plants annually in spring as they outgrow their containers. Mature plants may only need repotting every 2-3 years. Use a well-draining potting mix and a pot that is slightly larger than the current one.
