Time
The state windrow minimum is 15 days at 131 F with five turnings. We hold material for months, and some of it for years.
Water and turn
Piles stay aerobic. We water them during dry stretches.
Screen
Finished product runs through a trommel. Oversize comes out of mulch, compost, and blends. Clay chunks come out of the sand.
"It's a look, feel, and smell thing. All our products end up smelling the same, like earth, like soil."

Yes. We deliver in the Houston area with no minimum order, and we run split loads so more than one material can ride on the same truck. Past about 20 miles from the yard the delivery cost usually outweighs the cost of the material. Call or text +1 (281) 808-7955. Details are on the delivery page.
Wood shavings, animal manure, and food waste brought in by collection companies. We compost it at the yard, hold it for months, and screen it to half-inch minus. The full answer lives on our compost page.
Smell it. Finished mulch and compost smell like earth. A sour, vinegar, ammonia, or sulfur smell means it was sold too young. Nothing leaves our yard until it passes that test.
