Continuous climate change over the years has impacted various aspects of the Earth, including soil quality, leading to its degradation. To address this issue, one widely adopted solution is the use of ground cover plants, which help preserve topsoil, retain moisture, and regulate soil temperature, preventing excessive heat. A survey of the school revealed that several types of ground cover plants were cultivated around large trees, prompting the researchers to study how different types of ground cover plants affect changes in soil temperature and moisture. The study aims to provide insights into selecting the most suitable ground cover plants for effective soil management. A comparative study of four types of ground cover plants—Manila grass, Kyoto dwarf, Ceylon myrtle, and Spanish shawl—was conducted to assess their effects on changes in soil temperature and moisture during the day using custom-built equipment. The findings revealed that Spanish shawl was the most effective at maintaining stable soil temperature, followed by Ceylon myrtle, Kyoto dwarf, and Manila grass, respectively. Conversely, Manila grass was the best at retaining soil moisture, followed by Ceylon myrtle, Spanish shawl and Kyoto dwarf. Overall, Ceylon myrtle demonstrated the highest ability to maintain both soil temperature and moisture, followed by Spanish shawl, Manila grass, and Kyoto dwarf. These differences are likely influenced by factors such as stomatal structure and stomatal density. In conclusion, different ground cover plants have varying capacities to regulate soil temperature and moisture, depending on their leaf structures and plant characteristics. Selecting appropriate ground cover plants can significantly enhance soil preservation and management
