Water Acmella alba 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 in cooler periods to prevent root rot, but never let the soil become completely dry.

Prune Acmella alba to maintain a desired shape and encourage bushier growth. Pinch back the tips of stems regularly. Remove spent flowers to prolong blooming.

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

Propagate Acmella alba from stem cuttings. Take 7-10 cm cuttings from healthy stems, remove lower leaves, and dip the cut end in rooting hormone. Plant in moist potting mix or water and place in a warm, bright location.

Roots typically form within a few weeks.

Repot Acmella alba every 1-2 years or when the plant becomes root-bound. Choose a pot that is only slightly larger than the current one. Use a well-draining potting mix.

Repot in spring before new growth begins to minimize stress on the plant.
