Hydnora sinandevu is an obligate parasite and does not absorb water from the soil in the conventional sense. Its water needs are met through its host plant.

Therefore, regular watering of the Hydnora itself is not applicable. Focus on maintaining the health of its host.

Pruning of Hydnora sinandevu is generally not applicable or recommended. It is a subterranean parasitic plant with a unique morphology that does not lend itself to typical pruning practices.

Any interference could harm the plant or its host. Focus on maintaining the host's health.

Propagation of Hydnora sinandevu is exceptionally difficult and primarily occurs naturally. It relies on its host plant for survival and reproduction.

Human-assisted propagation is not a standard horticultural practice, and successful methods are not well-established for cultivation.

Repotting Hydnora sinandevu is not applicable as it is a root parasite that lives entirely within the tissues of its host plant. It does not have a root system in the soil that would require repotting.

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