ROCK GARDENS 
An Enthralling Personal Hobby 
Nature actually started this fascinating garden¬ 
ing feature; but modern gardeners, both profes¬ 
sional and amateui', are developing the subject with 
much enthusiasm, ingenuity and delightful effect. 
“Rock Gardens” may embrace acres of land broken 
up naturally in ridges, hummocks, valleys, pools 
and .waterfalls, with outcropping stones and pictur¬ 
esque existing trees. These natural settings in the 
right place are, unfortunately, rare; consequently 
we have to create such effects, by artifice. 
See Hardy Perennials, pages 33 to 47. 
Construction 
Location must, of course, be what have you. Lib¬ 
eral sunshine is much preferable; good drainage is 
essential. If your land is flat, dig a valley and 
build a mound. If there is an uneven corner spot, 
take advantage of it. 
Get together the best stones you can find ; some 
uneven boulders, more of uneven, irregular flat¬ 
tened pieces. Uniformity in size and shape should 
be avoided. Go easy on both very small stones and 
massive boulders. No bricks or concrete fragments. 
Soil is important. Mix a good porous garden 
loam with equal portions of both sharp, gritty sand 
and vegetable fiber—which may be leaf-mold, or 
decayed woods-turf, or Michigan peat. 
Distribute this soil on your basic construction, 
first; then crowd in and solidly anchor the stones, 
naturally commencing at the outer base, and work¬ 
ing up a gx-aduated slope towards the crest. In 
order to catch rainfall, dew or applied moisture 
and direct its drainage downward without loss into 
the thirsty soil, tilt the outer edges of slabs upward 
at least 10 degrees. In building rock walls, there 
car. be no vertical face but a graduated slope in 
successive tiers, its stones uptilted as above for the 
same reason. Wherever convenient, pack in the 
roots of plants designed to creep across and trail 
over the stones, as you go along. 
In apportioning relative stone and dirt areas, al¬ 
ways bear in mind that this is not a stone-pile to 
be screened but a garden in which the occuring 
stones are merely helpful, picturesque incidents. 
Tufted plants with rosetted foliage and moderate 
upstanding flowerstalks, are best suited to filling 
the narrower crevices. The creeping, trailing types 
spread densely over the flat surfaces, eventxially 
cascading downward over the edges in mossy trails 
of varied hue. In exterior supplementing groups, 
in occasional clumps of liberal area midway of the 
ascent, and prominently massed along the crest, 
there are many thrifty, colorful and dependable 
types. More ambitious plans at greater expense, 
with less restricted space and more emphatic topo¬ 
graphical features, welcome the enrichment of such 
units as Cotoneaster Horizontalis, Daphne, Tam- 
ariscifolia and other creeping Juniper, Azalea 
Mollis, Euonymus Vegetus, Yews, Savin and Pfitzer 
Juniper, Mugho Pine, Ilex, and an occasional ac¬ 
cent at balanced locations achieved by the slender, 
upright Junipers and Arbor-vitaes. 
The usual good watering at time of planting, 
must be. vigilantly repeated until you can be sui’e 
Nature is providing ample moisture. Your further 
responsibilities are: weeding, some .slight guidance 
of the trailers, replenishment of eroded soil, and 
straightening up and repacking if the heavier up¬ 
right plants become disturbed.
