Choosing the right amendment depends on your soil type, existing conditions, and the plants you intend to grow. Compost and other organic matter can help improve soil structure, while materials such as perlite and vermiculite can be useful when managing aeration and moisture retention. Testing soil before making significant amendments can help identify pH and nutrient conditions and guide your approach to soil improvement.
