WALL GARDENING 



Wall gardening has become one of the arts and it is not 

 possible to enter into so large a subject in so small a 

 space, but for those who have already a dry retaining 

 wall or two in their gardens the few plants here given, 

 which are so easily established and grow so readily in 

 such a position, may be of use. If the wall is an old one 

 there will probably be soil enough in the crevices to con- 

 tent those plants, but if fairly new, soil must be rammed 

 firmly back into the crack which we intend to plant. If 

 one has a wall to build and wishes to make of it a really 

 successful wall garden, it is advisable to procure one of 

 the many fascinating books which cover the subject. 

 Of those Miss JekylPs "Wall and Water Gardens," and 

 H. H. Thomas' "Rock Gardening for Amateurs" will be 

 found most helpful.
