Water Mecardonia acuminata regularly, keeping 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 during cooler periods, but avoid letting the soil become completely dry.

Prune Mecardonia acuminata to maintain a tidy shape and encourage bushier growth. Pinch back the tips of stems regularly, especially when young. Deadhead spent flowers to promote continuous blooming.

Heavy pruning can be done in early spring to rejuvenate the plant.

Propagate Mecardonia acuminata from stem cuttings. Take 7-10 cm cuttings from healthy stems in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone.

Plant in a moist, well-draining potting mix and keep in a warm, humid environment until roots form.

Repot Mecardonia acuminata every 1-2 years, or when the plant becomes root-bound. Choose a pot that is one size larger than the current one. Use a well-draining potting mix, such as a blend of peat moss and perlite.

Repot in spring before new growth begins.
