Bark mulch comes from a variety of trees, from cypress and cedar to pine, hemlock and oak.
One of the classic favorites is double shredded hardwood bark mulch. We typically use dyed dark brown mulch. The added color helps it stay nice and dark longer, without fading as quickly. It costs a bit more, but most people appreciate the rich, dark look throughout the year.
Rock mulch is decorative gravel or rocks ranging in size from pea-size to golf ball size, often sourced from river beds.
It’s available in a wide variety of sizes, colors, textures and shapes, from porous, lightweight red or black lava rock to pretty, smooth quartz gravel mulch in purple or pink. A bed of rocks with crisp, square corners punctuated with contemporary ornamental grasses creates a clean, modern feel.
The price of rock mulch varies, depending on the type and size, but generally costs about the same as an application of mulch.
But remember, it doesn’t break down and disappear into the soil like bark mulch does. You don’t need to replace it every year. So you may actually save money over time.
