Water moderately during the growing season, allowing the soil to dry slightly between waterings. Reduce watering in autumn and winter to prevent root rot.

Ensure good drainage to avoid waterlogged conditions, which this plant dislikes.

Prune lightly after flowering to maintain shape and encourage bushier growth. Remove any dead, damaged, or crossing stems. Pinching back young shoots can also promote a more compact plant.

Avoid heavy pruning, as it can stress the plant.

Hoffmannanthus can be propagated from stem cuttings taken in spring or early summer. Root cuttings in moist, well-draining potting mix, ideally with bottom heat. Once established, transplant into individual pots.

Seed propagation is also possible but slower.

Repot Hoffmannanthus every 2-3 years or when the plant becomes root-bound. Use a well-draining potting mix. Spring is the ideal time for repotting, just as new growth begins.

Gently loosen the roots and trim any circling ones before placing in a slightly larger pot.
