This slow growing geophytic taxon (generation length 20 years) is undergoing ongoing decline as a result of medicinal harvesting. Although the more widespread P. sidoides is predominantly targeted by pharmaceutical companies, P. reniforme is often harvested along with P. sidoides where the two species occur sympatrically in the Eastern Cape. Between 10 and 15% of the population is suspected to have been lost since 2002 due to widespread overharvesting. The demand for Pelargonium sidoides and related species is increasing and we suspect a minimum of a further 10% of the population of P. reniforme will be lost in the next 20 years.

Pelargonium reniforme is harvested for local use in traditional medicine. In addition, it is also often harvested in large volumes for large-scale commercial herbal medicine production, as it is vegetatively virtually identical to Pelargonium sidoides, which is a widespread and common species primarily targeted for international trade. Local extirpations and widespread decline have been observed around Grahamstown, Peddie and Alice between 2002 and 2012, and it is suspected that the population has been reduced by between 20 and 30%.
