HOW TO BUILD A ROCK GARDEN 
Select a gentle slope. Use the largest boulders 
possible, placing the bigger stones at the base, the 
strata all running the same. They should appear 
naturally placed. A few large rocks rather than 
many small ones is preferable. 
In the pockets between boulders there should be a 
rich, porous, moisture-holding soil at least two feet 
deep. Moisture in sufficient amount is the token of 
success, even more necessary than shade or part 
shade. 
Most entrancing groups of plants for Rock Gardens 
are low growing, brilliantly flowering, rather 
heavily foliaged Perennials. 
For interesting results the year round, include 
some dwarf Evergreens like Abelias, Azaleas, Daphne, 
Junipers, Retinosporas, Yucca, Yews, Pachysandra, 
Cotoneasters, for their touch of evergreen foliage, 
stability and the floral beauty of the blooming kinds. 
Low Annuals should always be added for continu¬ 
ous bloom throughout the Summer.
