Material glossary
Mulch and organics
Mulch and organics are the top layer that goes over the soil — bark, wood chips, compost, or a dyed blend. They hold moisture, slow weeds, and break down into the bed over a season or two. Different types last different lengths of time and read very different colors.
Every mulch and compost family we track is below. Pick by how long you want it to last and how it should look. We deliver the ones with a green pill; the rest are here for reference.

How to choose within mulch and organics
How much depth
2 to 3 inches is the sweet spot. Deeper starves the roots; thinner lets weeds through.
Color hold
Dyed mulches keep their color for a season, sometimes two. Natural mulch fades to grey within a few months.
Fine vs. coarse
Fine mulch breaks down into soil faster. Coarse mulch lasts longer and stays put on a slope.
