Pruning river clog plant — FAQ
When should I prune river clog plant?
After the primary flowering flush, usually late winter to early spring. Pinch or snip stem tips to a leaf node to encourage branching. Trim longer trailing stems back by one-quarter. Always cut back to leafy wood — bare stems on Nematanthus rarely produce new growth reliably if cut past all foliage.
How often does river clog plant need pruning?
Once per year post-bloom; light pinching and dead-stem removal as needed. River clog plant (Nematanthus fluminensis) is a trailing Brazilian gesneriad with small, tubular flowers. Like other Nematanthus, it needs only light post-bloom pruning to keep stems bushy rather than bare and straggling. Trim stems back by one-quarter after flowering. Remove dead or damaged growth whenever spotted. No heavy pruning is required or beneficial.
