Water Blumea axillaris regularly, allowing the soil to dry slightly between waterings. Ensure good drainage to prevent waterlogged roots, which can lead to root rot.

In warmer months, increase watering frequency, and reduce it during cooler periods or when the plant is dormant.

Prune Blumea axillaris to maintain its shape and encourage bushier growth. Remove spent flowers and any dead or damaged stems as needed.

Light pruning can be done at any time, but heavier pruning is best in early spring before new growth begins.

Blumea axillaris can be propagated by seeds sown in spring or by stem cuttings taken in late spring or early summer. Seeds can be sown in a well-draining seed-starting mix and kept moist.

Cuttings should be rooted in moist potting mix.

Repot Blumea axillaris every one to two years, or when it becomes root-bound. Choose a pot that is slightly larger than the current one and ensure it has drainage holes.

Use a well-draining potting mix, such as a standard houseplant mix with added perlite.
