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

Reduce watering slightly during winter months when the plant's growth slows down. Overwatering can lead to root rot.

Prune Justicia pectoralis to maintain a bushy shape and encourage more blooms. Pinch back the tips of new growth regularly. Remove any dead, damaged, or leggy stems.

Pruning can be done in spring before new growth begins and lightly throughout the summer.

Propagate Justicia pectoralis from stem cuttings. Take 10-15 cm cuttings from healthy stems in spring or summer. Remove lower leaves and plant them in moist potting mix or water.

Roots typically form within a few weeks, after which they can be transplanted.

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

Repot in spring before the active growing season begins.
