Water Chromolaena ascendens thoroughly when the top 2-3 cm of soil feels dry. Avoid overwatering, as this can lead to root rot.

Reduce watering in winter when the plant is dormant, allowing the soil to dry out slightly more between waterings. Ensure good drainage to prevent waterlogging.

Prune Chromolaena ascendens in late winter or early spring to shape the plant and encourage bushier growth. Remove any dead, damaged, or crossing branches.

Pinching back the tips of young shoots can promote a more compact and desirable form. Deadheading spent flowers can prolong blooming.

Propagate Chromolaena ascendens from stem cuttings taken in spring or summer. Select healthy, non-flowering shoots, cut them to about 10-15 cm long, and remove the lower leaves.

Dip the cut end in rooting hormone and plant in a moist, well-draining potting mix. Cover with a plastic bag to maintain humidity.

Repot Chromolaena ascendens every 2-3 years, or when it becomes root-bound. The best time to repot is in spring, before new growth begins.

Choose a pot that is only slightly larger than the current one and use a well-draining potting mix. Water thoroughly after repotting.
