For low rockery or on slight slopes, the rocks 
are placed as shown in this illustration. Plenty 
of good well drained soil under and between 
the rocks is essential so that the plants will take 
hold and make a good growth.

Location. The average city or suburban property readily provides ample space for the little 
rock garden. It may be located between the driveway and the lot lines near the garage—in the 
bare space next to the house between side or rear group foundation plantings, next to the 
side of the garage, or in any available space on the property not being used, such as on the 
terrace between two garden levels. 
Begin at the bottom and build upward. Each stone or boulder should be placed in such 
a manner as to allow the moisture from rains to run into the garden and not away from it. 
After placing a stone, fill around it with earth, being sure that there are no spaces unfilled, as 
air spaces will prevent moisture from coming up from below. The crest or top of the rockery 
must have direct contact with soil, by way of firmness in the filled in earth. Be sure that the 
earth is filled in solidly so that moisture will work up among the stones and give proper condi¬ 
tions for the growing of rock plants. A rockery need not be any more than 10 to 12 inches 
above the surrounding level. 
The soil in which the plants are placed should be of good character. Use peat moss or leaf 
mold and good rotten manure to mix with your garden soil. The main body of the rock gar¬ 
den; can be ordinary garden soil, but the top soil wherein the plants are placed should be 
of richer character. 
Herewith is given a list of hardy perennial plants, especially adapted for rock culture. With 
this material you can build a splendid rockery complete in every detail. Do not overlook 
the fact that this stock is two years old and usually sells at 25c each.
