Water Justicia axillaris regularly, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings.

Reduce watering during the cooler, dormant winter months to prevent root rot. Ensure good drainage to avoid standing water.

Prune Justicia axillaris in late winter or early spring before new growth begins. Trim back leggy stems to encourage bushier growth and a more compact form.

Remove any dead or damaged branches at any time of year to maintain plant health and appearance.

Propagate Justicia axillaris from stem cuttings taken in spring or summer. Select healthy, non-flowering stems, cut them to about 10-15 cm, remove lower leaves, and dip the cut end in rooting hormone.

Plant in moist potting mix and keep in a warm, humid environment.

Repot Justicia axillaris every 1-2 years, or when it becomes root-bound. Choose a pot that is one size larger than the current one. Use a well-draining potting mix.

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