Rock Gardens
While "Rock Gardens" is the modern name, another term used in
connection with natural rock gardening is "rockeries". The
biggest problem is to determine the plants that are likely to
succeed under the conditions that can be provided. There are no
plants that can be counted as rock plants in every part of the
country; therefore, plants must be selected for the particular
locality where they are to be grown. The background or setting
for the rock garden varies greatly because of the topography and
character of the country. In a rough, rocky country rock garden
sites are sometimes found almost readymade, but in other
sections they must be created from materials collected for the
purpose. In the latter case care is necessary in order to
produce a result that does not look forced or out of place. When
building a house on a rocky hillside it may often be possible to
reserve an adjacent area that may be made into a most attractive
garden with but little modification. Even old quarries can be
and are converted into attractive gardens. Where, however, such
features have to be built, it takes a good student of nature to
reproduce naturalistic rock ledges and other stone outcroppings.
Boulders (rounded, waterworn stones) may be scattered over a
gentle slope, whereas on a steeper slope the stones must be
placed close together, at some points even resting on one
another. Even rock walls may be part of a rock garden.
Rock Walls Quarried or angular field stones often may be
appropriately used to hold artificial banks. Stones with
weathered faces are usually more attractive than those with
newly cut or broken faces. Where there is a gentle slope, a row
of stones may be placed at the bottom, with spaces between them
two or three times as wide as the stones; other stones may be
placed behind these spaces with the bottom as high as the tops
of the front stones and back far enough to hold the soil at the
desired slope. Where the bank is steep the space between the
stones, often only 2" or 3", may be filled with soil and the
next stone laid over this opening, resting on both the lower
stones and set as far back as the desired slope of the wall will
permit. Stones should not be uniform in size, and those more
irregular in outline than is desired for building purposes make
a more attractive wall. If the stone has a relatively flat upper
surface, the surface should be so placed that water falling on
it will drain back into the wall and not off.
Oftentimes, even with best of intentions, it's just difficult to
get anything to grow. In these circumstances, garden planters or planting containers may be called for. You can use
whatever soil, and plant whatever you like in containers.
