Water
Water thoroughly when the top 2-3 cm of soil feels dry. Avoid letting the plant sit in water, as this can lead to root rot.
Reduce watering frequency during the cooler, dormant winter months, but do not allow the soil to dry out completely.

Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the top 2-3 cm of soil feels dry. Avoid letting the plant sit in water, as this can lead to root rot.
Reduce watering frequency during the cooler, dormant winter months, but do not allow the soil to dry out completely.
Prune to maintain shape and encourage bushier growth. Trim back leggy stems by cutting just above a leaf node. Remove any dead or damaged foliage promptly. Pruning can be done at any time, but is best after flowering.
Propagate from stem cuttings. Take 7-10 cm cuttings from healthy stems in spring or summer. Remove lower leaves and dip the cut end in rooting hormone. Insert into a well-draining potting mix and keep moist and warm.
Repot your Columnea angustata 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 peat-based mix with added perlite.
