II. — The Alpine Garden. 1 



The term "alpine plants" is used to include 

 many which are not mountain plants at all; 

 it is here applied to ornamental hardy plants 

 of low stature, such as may be successfully 

 grown among large stones, either facing a bank 

 or elevated above the level of the ground. 



There are some' favoured gardens where 

 natural rockeries exist, or where the conditions 

 of the soil with regard to quality or drainage 

 are such that choice and delicate mountain 

 plants may be grown on the ground-level in 

 ordinary borders. Such gardens exist in several

districts in England, and are common in Scot- 

 land and Wales; few rules are necessary there, 

 where plants have only to be planted and kept 

 clear of weeds in order to thrive. 



But most of us who wish to grow choice 

 alpines in our gardens have to make the best 

 of conditions naturally unfavourable, and in 

 doing this we can be helped by the experience 

 of those who have made it their special study. 



The first necessity for growing choice alpines 

 is to secure perfect drainage for the soil in 

 which they grow. Supposing that no part of 

 a garden naturally gives the conditions in 

 which alpines will thrive, we must make these 

 conditions by artificial means. Those who wish 

 to grow them on flat borders on retentive wet 

 soils may do so on the ground-level by digging 

 out the soil to a depth of 3 feet, and drain- 

 ing the bottom of the bed to the nearest outfall. 

 and filling up to the surface with soil mixed 

 with two-thirds of broken stone, either in small 

 or large pieces. But in heavy soils, where large 

 stones are easily obtained, still better beds for 

 alpines may be made by enclosing the space 

 with large blocks to a height of 2 or 3 feet, 

 and filling up as before directed. The sides 

 of these stone blocks can be covered with many 

 ornamental plants in addition to those which 

 are grown on the raised surface. 



The commonest way of cultivating alpines is 

 upon what are called rockeries, or loose rough 

 stones laid together in different forms and 

 methods. The forms in which a rockery can 

 be constructed may be divided into three: 

 (1) The barrow-shaped rockery, (2) the facing 

 rockery, and (3) the sunk rockery. The first 

 may be raised anywhere, the other two depend 

 partly upon the configuration of the ground. 

 No wood or tree-roots should be used to sup- 

 plement any of them; they must be all stone. 

 The kind of stone is seldom a matter of choice; 

 everyone will use what is most handy. The 

 rougher and more unshapely the blocks the 

 better. The size should vary from -40 or 50 lbs. 

 to 3 or 4 cwts. No mortar or cement for fixing 

 them together must ever be employed: they 

 must be firmly wedged and interlocked, and 

 depend upon one another, and not upon the 

 soil between them, to keep them in their places. 

 This rule is of the utmost importance; if it is 

 neglected, a long frost or an excessive rainfall 

 may cause the whole structure to collapse. 



Each successive part of the stone skeleton 

 must be put together before the soil is added. 

 This applies to all rockeries.
