Water Andrographis paniculata consistently, allowing the top 2-3 cm of soil to dry out between waterings. Avoid waterlogging, as this can lead to root rot.

Reduce watering slightly during cooler, dormant periods, but do not let the soil become completely dry.

Prune Andrographis paniculata to maintain a bushy shape and encourage branching, which can increase yield. Pinch back the tips of young plants and remove any leggy or overgrown stems.

Pruning can be done year-round as needed, but is most effective in spring.

Propagate Andrographis paniculata from seeds sown in spring or from stem cuttings taken in late spring or early summer. Seeds can be sown directly into well-draining soil and kept moist.

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

Repot Andrographis paniculata every 1-2 years, or when it becomes root-bound. Choose a pot that is only slightly larger than the current one. Use a well-draining potting mix, such as a blend of potting soil and perlite.

Repot in spring before active growth begins.
