A type of Rock Garden easily adapted to any location. 
The Pool and Rock Garden usually belong together. 
The Rock Garden 
O NE of the most delightful things about a rock garden is that you can build it in summer 
when the weather is fine and all the rush of other garden work is over. In many a garden, 
slopes and gullies which seemed devoid of possibilities have been transformed into fascinat¬ 
ing features, where species unsuited to the regular plant borders find favorable conditions. 
No matter how limited your space or seemingly devoid of possibilities and regardless of the 
location, you can have an example of this “most different’’ type of garden. Some of the most 
attractive rock gardens have been made in small nooks and corners. 
The difficult problem to many is the acquisition of rock material. While stones of various kinds 
are found in nearly every part of the country, there are places where their absence may 
present a real obstacle. 
The more porous the stone, the more moisture will be retained in reserve, during dry periods. 
Tufa, hard sandstone, coral rock, and rock which has become honey-combed through weathering, 
are excellent types for our purpose. 
Where rock is difficult to obtain, clinkers dipped in thin cement have been used very cleverly. 
They make an effect resembling tufa, and large ones are obtained by cementing together small 
pieces. 
In constructing a rock garden of boulders, or 
similar material which is non-stratified, select 
pieces in various sizes; it is important that 
some large stones be used in the composition. 
This will tend to give character to a garden of 
this type. 
Rock plants generally prefer a light porous 
soil, which is not too rich. They seem to bloom 
better when they are starved somewhat. If your 
soil is heavy with clay, use some sand, gravel, 
stone chips, or cinders to lighten it, also mix 
in humus. 
To start your rock garden, excavate to a 
depth of two feet and put in six inches of cin¬ 
ders. A tile drain can lead off from this if 
necessary. If the subsoil is a heavy clay twelve 
inches of drainage material should be used. 
After drainage has been installed, fill in the 
remaining depth with soil. You are now on the 
level with the natural grade, and you can start 
your rock construction. Put in place the first 
or bottom layer of rocks and tamp thoroughly 
around them to prevent air pockets and settling 
and be sure that they tilt backward slightly and 
not forward. Keep rough and weathered edges 
to the front to simulate naturalness and age. 
Use broken rock mixed with soil back of rocks. 
Be sure that sufficient good soil is placed under 
the stones for the plants to grow in. Build up 
with sufficient layers, until you have reached 
the desired height. When planting, place the 
roots deeply into the recesses. 
For the maintenance of a rock garden, water 
frequently in summer. 
We recommend the following Annuals for use in the rock garden: 
ALYSSUM (Page 1) DIANTHUS (Page 3) PORTULACA (Page 6) 
ASTER (Page 1) PETUNIA (Page 6) SNAPDRAGON, Half Tall (Page 7) 
CYNOGLOSSUM (Page 3)CALIFORNIA POPPY (Page 5) VERBENA (Page 8) 
ZINNIA, POMPON (Page 9) 
TROPICAL CORAL ROCK very beautiful, coming in colors of white, cream, and very often mottled. 
No two pieces alike. Nothing like it for use around a pool or in a rock garden. Generous sample: 
20c; $1.00 to $5.00 assortments; $10.00 per barrel (F.O.B. Ojus, Fla.) A $1 collection contains 
about a dozen beautiful pieces.
