Water Blumea lacera regularly, allowing the top inch of soil to dry out between waterings. Avoid overwatering, as this can lead to root rot.

Ensure good drainage in pots or garden beds to prevent waterlogging, especially during its active growing season.

Pruning Blumea lacera primarily involves deadheading spent flowers to encourage further blooming and prevent seed formation if desired. Lightly trim back leggy or overgrown stems to maintain a more compact shape.

Pruning can be done anytime it looks untidy.

Blumea lacera is easily propagated from seeds sown in spring or early summer. It can also be propagated from stem cuttings taken during the growing season.

Cuttings should be rooted in a moist, well-draining medium in a warm environment.

Repot Blumea lacera when it becomes root-bound, typically every one to two years. Choose a pot that is only slightly larger than the current one. Use a well-draining potting mix.

Repotting is best done in spring before the active growing season begins.
