Cistanche fissa is a parasitic plant and does not require traditional watering. It obtains its water and nutrients from its host plant. Overwatering can be detrimental to both the parasite and its host.

Ensure the host plant is adequately hydrated but avoid waterlogged conditions.

Pruning of Cistanche fissa is generally not necessary or recommended. Its growth is dictated by the host plant's life cycle.

If any part of the plant appears unhealthy or diseased, it is often indicative of a problem with the host plant. Remove any affected parts carefully to prevent spread.

Propagation of Cistanche fissa is challenging and primarily occurs through the germination of seeds, which are dispersed by wind or animals. Successful establishment requires the presence of a suitable host plant for the seedling to parasitize shortly after germination.

Repotting is not applicable to Cistanche fissa as it is a parasitic organism that grows attached to the roots of its host plant. It is not grown in a containerized medium.

Its existence is entirely dependent on the host's root system.
