For the gymnotheca genus, select a well-draining soil with moderate fertility, as overly rich soil can diminish flowering. They require partial shade to full shade, with protection from intense afternoon sun. Maintain consistent moisture without waterlogging the soil. To plant, dig a hole twice the root ball's width, place the plant at the same depth it grew in its pot, and water thoroughly. Mulch to retain soil moisture. While most species share these needs, always check the specific requirements of your chosen species.
