The kohleria genus is well-suited for indoor growing, thriving in humus-rich, well-draining soil and living under bright, indirect light. It should be watered when the top inch of soil is dry, while avoiding waterlogging. You can plant kohleria by preparing a pot with the right soil mix, placing the plant and firming the soil around it. Maintain a steady temperature and high humidity for optimal growth. The needs can vary across species, so it's essential to research your individual plant's requirements.
