Japanese Garden Gravel: Specifying the Right Material in the Midwest

Authentic karesansui (dry garden) gravel isn't just "rock"—it's a specific texture, color, and size for raking.

Ideal Specifications

• Material: Crushed granite (angular, not rounded).
• Color: Whitish-gray with black speckles (salt-and-pepper).
• Size range: ⅛" to ¼" (barley grain to small pea). Uniform gradation.
• Depth: 2–3" over compacted base + weed barrier.

Midwest Sourcing

• Search "crushed granite chicken grit" or "decomposed granite fines" at landscape supply yards.
• Avoid pea gravel (round, rolls), limestone (too white, compacts hard), slag (sharp, metallic).
• Request a sample bucket before bulk delivery.

Raking & Maintenance

• Use a wide, fine-tooth wooden rake (aspect ratio ~1:4).
• Patterns: parallel waves, concentric circles, checkerboard.
• Re-rake after rain/wind; meditative practice.

True Japanese gardens use local stone. Midwest granite fits the aesthetic perfectly.
