i66 How to Make a Flower Garden 



The approaches to a rock garden shoukl not be too abrupt ; a few rocks 

 placed outside along the path leading to the rock garden, and also among 

 the shrubs which enclose it, help to give it a much more natural appearance 



The propagation of alpine and other plants suitable for rock gardens 

 is simple. All may be raised from seeds, and most of them by cuttings or 

 division of the plants. The writer raises his plants from seeds sown m 

 February, in four -inch pots of light sandy soil, in a warm greenhouse. The 

 seedlings are transplanted as soon as large enough to handle, and gradually 

 given more air as they increase in size. By the end of April they are usually 

 large enough to plant out permanently in the rock garden. If one does 

 not have a greenhouse, the seeds may be sown m a coldframe, in shallow 

 drills, in April, and transplanted to the rock garden in early fall. 



The whole rock garden should be replanted and given fresh soil about 

 every four o^ "^.ve years. The general care required is usually less than 

 for an ordinary flower garden. In dry weather in summer the plants should 

 receive water at least once in two days, and in winter the plants which over- 

 hang ledges of rock should be protected with branches of hemlock or pine. 



Following is a list of some of the plants most suitable for a rock garden, 

 the majority of which the writer has proved to be hardy in New England.
