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 are preferable. 
Ih the pockets between boulders there should be a 
rich, porous, moisture-holding soil at least two feet 
deep. Provide moisture in abundance. 
Most entrancing groups of plants for Rock Gardens 
are low growing, brilliantly flowering, raJher 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 kind. 
Low Annuals should always be added for con¬ 
tinuous bloom throughout the Summer.
