Topsoil serves as the foundation for healthy plant growth, making it essential for gardeners and landscapers alike. This layer, rich in organic matter and nutrients, creates the perfect bed for planting, helping roots establish and spread with ease. Ideal for filling beds or raising planting levels, topsoil also supports moisture retention, which is especially valuable in periods of dry weather. Unlike subsoil, topsoil teems with beneficial microorganisms that break down organic material, releasing nutrients plants need to thrive.
