Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water Justicia metallica regularly, keeping the soil consistently moist but not waterlogged. Allow the top 2-3 cm of soil to dry out slightly between waterings.
Reduce watering frequency during winter months when the plant's growth slows down. Ensure good drainage to prevent root rot.
Prune Justicia metallica to maintain its shape and encourage bushier growth. Pinch back the tips of stems regularly, especially in spring and summer. Remove any leggy or dead stems to promote new vitality.
Heavy pruning can be done in early spring before new growth emerges.
Propagate Justicia metallica from stem cuttings, typically taken in spring or early summer. Cuttings of 7-10 cm with several leaves can be rooted in moist potting mix or water.
Keep cuttings warm and in bright, indirect light until roots develop.
Repot Justicia metallica 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.
Repotting is best done in spring, coinciding with the start of the active growing season.
