#89 Stone vs Topsoil: Size, Cost, and Which to Use

#89 Stone

In the ASTM C33 sieve table, #8 stone passes a 1/2-inch screen and stays on a #8 sieve (about 3/32 inch), and #9 is a step finer. #89 is a blend of the two: most of it passes a 3/8-inch screen and stays on a #16 sieve. In practice you get a clean, small, sharp stone that looks like crushed pea gravel. Some quarries sell the same product as #8, #9, or "3/8 clean."

Topsoil

Nutrient-rich upper layer of soil, ideal for establishing lawns, gardens, and planting beds. Quality topsoil is dark, crumbly, and full of organic matter that supports plant growth. Screened topsoil has been filtered to remove rocks, roots, and debris.

#89 Stone

#89 stone is crushed stone screened to about 3/8 inch and smaller, with most pieces between 1/8 and 3/8 inch and no dust. It is angular, a blend of the #8 and #9 sieve sizes. Color follows the quarry: gray or white limestone, gray to pink granite, or dark basalt.

Topsoil

Fine, crumbly soil texture when screened. Dark brown to black color indicates high organic content. "Screened" topsoil has been run through a 3/8" or 1/2" screen to remove debris. Blended topsoil may include compost for extra nutrients.
