Pea stone is a rounded aggregate,
often in ornamental colors such as white or blends of tan and brown. It can be used as a surface
material for a walkway, patio or driveway. Although more expensive than
ordinary crushed stone, it is still a low-cost material. Since it is not
solid, like brick or flagstone, a pea stone surface will eventually need some maintenance, such as weeding and an
occasional raking. It is not suitable to areas where snow needs to be
plowed or shoveled.
Pea stone surfaces need some kind
of edging in order to maintain a separation to abutting surfaces. A
granite cobblestone edging retains the loose pea stone, keeps mulch and soil
out and gives the walkway a great definition.
Pea stone is not a good material for
entrance walkways, since it happens easily that small pebbles are wedged
in under a shoe and than tracked into a building, where they will ruin
a wood floor in a short time. |

Another walkway material is
bark mulch. If the path leads through a garden one does not need to install
an edging, since the garden bed is covered with the same material. Weeds are
usually less of a problem than with pea stone, as long as the mulch layer is thick enough. It
should not exceed 1 inch in the bed since many plants are sensitive to heavy
layers of mulch, but it can be much
thicker on a path.
Obviously, a mulch path is best
installed in a garden or woodland. Close to the house, it will track mulch
particles into the home. |

An example for a pea stone surface: |
|
|
|
3
|
|
4
All borders of the pea stone surface are edged with
walls or curbstone. |
|
|
|
|
5
The sitting area is separated from the parking by
small beds that are planted with Fritsch Spirea (Spirea fritschiana)
which will form 3-ft.-mounds of lush foliage. |
|
6
Tables have been placed in the sitting area for use
by the customers of this café and bakery. The top
of the sitting-wall is planted with culinary herbs and lavender. |
|

|
7
The same area during construction. The surface
has been cleaned and is ready for excavation of the patio space. |
|
8
The patio space is prepared with a layer of 3/4
crushed stone in order to insure perfect drainage and avoid a wet surface.
After compaction a layer of stone dust is installed on which the pea stone is
spread out. |
|

|
Another project with pea stone and
granite edgings: |
|
|
9
This patio space on the south side of a home is
edged with a mix of blocky wall stone and cobblestone. |
|
10
Once the surrounding gardens and center island
have grown in the edging will be softened and the tan colored pea stone will
contrast with the green of the garden. |
|
|
|
|

|
To minimize tracking of pea stone into
the house slabs of bluestone have been placed in the entrance area.
Larger size pea stone, or round stone,
can also be used for patios and walkways. It is not as comfortable to walk
on, but it has the advantage that it does not track into the house. |

There are two important traditional uses for
pea stone in landscaping:
12
First, it is used in oriental gardens, where it is
often raked to achieve a texture that is reminiscent of waves in the
ocean. |
|
The second important use is in formal herb gardens
and rose gardens. Gardens of renaissance palaces often had extensive systems
of walkways and paths that were covered with pea stone. |
|
|
|
To facilitate maintenance, it
is possible to install landscape fabric under a pea stone walkway, like
shown in the following photos. This is especially beneficial if the area
is small and surrounded by gardens from where weeds could grow into the
walkway. |
13
Installation of a very basic pea stone walk with no base of crushed
stone: The soil is cleaned and leveled. Liner is placed on the soil in
the shape of the desired pea stone area.
|
|
14
The liner is covered with stone dust. The edges of the liner are pulled
upward by one or two inches in order to form a barrier between stone dust and
soil. Screened loam is filled in from the back to support the liner and to
adopt the liner edge to the grade of the surrounding garden beds.. Rocks
can be used as edgings or ornaments. |
|
Mulch as a surface material: |
|
|
|
15
In this location, building restrictions did not allow for stone work,
and a path covered with bark mulch was installed instead.
A liner can also be installed, in the same way as described above, to
minimize weed growth on mulched areas.
|
|
16
Garden beds and mulch walkway form one unit. Mulch is
also suitable for woodland paths and is a nice material to walk on. |
