Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water Coleus barbatus thoroughly when the top 2-3 cm of soil feels dry. Allow excess water to drain away completely to prevent root rot.
Reduce watering frequency during cooler months or when the plant is not actively growing, but do not let the soil become bone dry.
Pinch back the growing tips regularly to encourage bushier growth and prevent the plant from becoming leggy. Prune away any dead or yellowing leaves as soon as they appear.
Harder pruning can be done in spring to reshape the plant and stimulate new growth.
Coleus barbatus is easily propagated from stem cuttings. Take 10-15 cm cuttings from healthy stems in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone (optional).
Plant in moist potting mix and keep in a warm, bright location.
Repot Coleus barbatus 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, such as a combination of potting soil, perlite, and peat moss. Repot in spring before the active growing season begins.
