Sizes & Colors

#8 Gravel

#8 gravel consists of angular crushed stone pieces from 3/8" to 1/2" in diameter. Like other crushed stone, color varies by source quarry — gray, blue-gray, tan, and brown are most common.

Compost

Fine, crumbly texture when fully decomposed. Dark brown to black color. Should smell earthy, not sour or ammonia-like. Screened compost has been filtered to remove large uncomposted pieces. Mushroom compost is a byproduct of mushroom farming and is particularly nutrient-rich.
