Frequently Asked Questions

Why choose shredded cedar over regular bark for playgrounds?

Western Red Cedar is naturally rot-resistant, aromatic, insect-repellent, and less prone to splintering than hardwood bark.

Is bulk delivery cheaper for a 20x20 area?

Yes. At 5.4 cubic yards (73 bags), purchasing bulk mulch delivered by a single-axle dump truck saves roughly 40-50% compared to buying individual retail bags.
