Rock gardens involve growing mountain plants

that can withstand severe winter cold.Development of rock garden is also possible in

warm temperate, sub tropical and tropicalclimates as in temperate ones.

Many rock gardens feature different kinds ofplants.

1. Terrestrial plants

These plants found in warm climates

quite obviously differ from those grown in colderones.

In desert and semi desert areas,cactuses and other succulents grow well. They

look especially good in association with rocks.

It is always better to select plants that grow in the

soil available instead of changing the soil to suitthe plant.

As such, rock garden plants do not require heavysoil.

Chips of crushed rock, coarse sand, perlite orcrushed limestone or chrushed oyster shells canbe used to improve the soil texture in rockgardens.

Use soil that has been fertilized and light intexture. This soil will facilitate water drainage.

When choosing a location for your rock garden,look for a slope that will have good waterdrainage. Water trapped between the rocks cancause plants to rot.

Good drainage, light, pure air and a healthy soil

are essential ingredients for design andconstruction of rock gardens.Plants should be arranged in such a design that

they look natural.

There is no symmetry of design in rock gardens.Evenness in size or distribution looks unnatural inrock garden design. The rocks should not bedistributed evenly as this will look very artificial

Gardens look best when they are bold and large,rather than puny and trivial. The rocks should all

be of the same source, but of different sizes.Avoid placing them regularly.In artificial rock gardens, there should be no

impression that rocks are separate and they can

be loosened and removed.The soil should be firmly packed and rocks should

be placed in the best possible positions.Landscaping with rock is an art. When

constructing rock gardens, the plantings amongstthe rocks take center stage. Popular rockgardening are alpine design rock gardens and Zenand Japanese gardens.

The first step in creating rock gardens is to

evaluate the area with reference to thecontouring and availability of rocks.This is because rocks from the area will blend

nicely and naturally into the garden.

Appropriate sites for natural rock gardens areslopes, banks, and small valleys or dells. Pools,streams and waterfalls greatly add to the beautyand charm of rock gardens.

Artificial rock gardens are constructed in placedwhere native rock formations are not available.

Artificially created gardens that mimic native rockformations can be seen in Europe and America.

The rock usually used in rock gardens is porous.Hard impervious types of rocks such as granites

are not preferred. Hard sandstone is very good.Soluble limestone is not advised.

Instead, a soft light weight porous limestone rockcalled 'Tufa' can be used as it is very congenial toplants.

Hard rocks are unsuited as they take long time to

weather. They also do not encourage the growthof plantations like mosses and lichens.

Rock gardens demand regular care. Rock plants

succumb to extreme summer humidity andharsh winter conditions.

Propagation of rock plants is an importantaspect of rock gardening. Many of the

plantations in the rocks are short lived.It is always better to have a stock of plants for

replacement.Spring is the best time of the year to propagate

rock garden plants. September is also anexcellent time for some of the rock plantcultivation.

The Zen rock garden emphasizes form, foliageand structure.

While showy flowers are central to Western rockgardens, a Zen rock garden is more austere andsimple.

A Zen rock garden is often suggestive of alandscape of islands in the sea. Island stones arecarefully selected and placed.

Clean gravel is put around them in patternsresembling waves and currents.

Japanese rock gardens are built on certain

basic design principles. The Japanese believethat one cannot and should not createsomething artificial in nature.

A key point to remember in Japanese rock

gardens is balance or 'sumi.You are always trying to create a large

landscape even in the smallest of spaces. Thecomponents have to be chosen with care.

The right kind of balance should be struck.A small stretch of raked sand is suggestive of an

entire ocean. 'Less is more' is definitelyapplicable to Japanese rock gardens.

The elements of time and space are important

Crevices are those intriguing gaps between rocks where plants cangrow while seeming to defy all odds. They can be found in

horizontal and vertical spaces such as those found in rock walls orin the gaps between pavers on a pathway. In rock gardens, weoften intentionally create small spaces between rocks in which totuck our plant treasures. Alpines and other rock garden plants areideally suited to grow in these spaces as they often do in nature.
