For the ridolfia genus, choose well-draining soil and a sunny location to promote healthy growth. Water requirements may vary, but generally, ensure consistent moisture without waterlogging. Start by loosening the soil and mixing in organic compost to improve fertility. Space the ridolfia plants according to their mature size, allowing room for expansion. After planting, water thoroughly and add a layer of mulch to retain moisture. As best practices, regularly check for pests and diseases. While these guidelines suit most ridolfia species, specific care for particular species may differ.
