Water moderately when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this species is susceptible to root rot.

Reduce watering significantly during its dormant period, typically in cooler months, allowing the soil to dry out more between waterings.

Pruning is generally not required for Rhizanthes deceptor. However, remove any dead, damaged, or discolored leaves or stems promptly at the base to maintain plant health and aesthetics. Avoid cutting into healthy tissue.

Propagation is primarily achieved through specialized techniques for parasitic plants, often involving specific host plant associations or tissue culture, which are complex and not typically suited for home propagation. Natural spread is rare.

Repotting is rarely necessary as Rhizanthes deceptor is a root parasite and does not have a traditional root system that fills a pot. If a host plant is established in a container, the parasitic plant grows on it.

Avoid disturbing the host plant.
