Decorative Stone and Gravel Mulch

Decorative Gravel and Landscape Stone
Homeowners sometimes get weary of refreshing wood mulches, and decide to use decorative stone mulch instead. Boulders can add interest to garden beds.

WOOD MULCH OR STONE?
While the initial installation of decorative stone is considerably more tedious and expensive, it can pay dividends in the long run. Bob shares his photos here of the more commonly used decorative landscape stone like river rock, shore gravel and lava rock.

Wow, this big rock is hard to handle!

Decorative stone basics

Most stone and gravel is graded with numbers related to its size. For example, #2 is likely two-inches in diameter and #3 is three-inches in diameter. Some of the photos below have a 12-ounce can of soda or a Quarter to help show stone sizes.

LANDSCAPE FABRIC
While Bob doesn’t recommend using landscape fabric (or black plastic) under wood mulches, he does recommend using landscape fabric under stone mulches. It is also advisable to use tarps when trimming shrubs that are growing in decorative rock landscape beds to ease clean-up and keep decorative gravel clean.

Shore Stone

Shore stone is a lighter color and costs more than more commonly used river rock, which is usually brown in color.

River Rock

River rock is typically used in landscape beds where a brown color and more permanent cover than wood mulch is desired. Using mixed sizes helps fill-in the gaps between larger stones.

Bob’s Wheelbarrow Tips
  1. To move landscaping materials, buy a good quality wheelbarrow with a pneumatic tire, strong wooden handles and 4 to 6 cubic foot capacity. Maintain the correct tire pressure, oil the axle occasionally and store it out of the weather.
  2. Take partial loads when moving heavier materials like stone and soil.
  3. Load most of the weight toward the front of the wheelbarrow to balance the load and keep weight off the handles (..it’s one thing to push a heavy load, another to have to lift it at the same time!).

Load weight toward the front!

Soil is properly distributed in this wheelbarrow, creating better balance for easier “wheeling.” Before starting, inflate tire to recommended pressure (found on the side of the tire as “PSI” or Pounds per Square Inch) prior to moving heavy loads.

Boulders and landscape rocks

Boulders add a nice accent to landscape plantings, but only use the types of stone resistant to the freeze-thaw cycles of winter weather. Special care should be taken when moving and placing boulders to save on smashed fingers and bad backs.
