Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water Justicia carthaginensis regularly, keeping the soil consistently moist but not waterlogged. Allow the top 2-3 cm of soil to dry out slightly between waterings, especially during warmer months.
Reduce watering in cooler periods to prevent root rot, but never let the soil become completely dry.
Prune Justicia carthaginensis to maintain its shape and encourage bushier growth. Deadhead spent flowers regularly to promote continuous blooming.
Light pruning can be done anytime, but heavier pruning is best performed in early spring before new growth emerges. Remove any leggy or overgrown stems.
Propagate Justicia carthaginensis from stem cuttings taken in spring or early summer. Select healthy shoots, cut them to about 10-15 cm long, and remove lower leaves.
Dip the cut end in rooting hormone and plant in a moist, well-draining potting mix. Cover with a plastic bag to maintain humidity.
Repot Woodland water-willow every 1-2 years, or when it becomes root-bound. Choose a pot one size larger than the current one with good drainage holes.
Use a well-draining potting mix, such as a blend of potting soil, perlite, and compost. Repot in spring, just as new growth begins.
