Understand Raised Planter Drainage and Structure

What happens here

The video begins by showcasing a raised planter, which is typically constructed as a retaining wall. Behind such structures, a substantial amount of stone (like gravel or crushed rock) is commonly used. This stone serves two crucial purposes: first, it acts as a drainage layer to prevent hydrostatic pressure buildup against the wall, allowing water to exit freely. Second, it often provides a stable and robust base for an adjacent patio or an upper-level hardscape. The inherent challenge then becomes how to effectively plant vegetation in this stone-filled environment.
