appropriate choice of plantsIn view of current and future climatic
conditions, appropriate plant selection is critical to achieve beautiful
gardens that are sustainable. Water
restrictions are now common place, so reducing high water use plants is the
logical way forward. By
choosing appropriate species you can create a garden with style that will
reduce environmental impact and be appropriate to local conditions. Considering the different micro climates in a
garden or landscape provides opportunity for diversity. For instance, a naturally moist area shaded
by a tree would suit plants that originate from dense, temperate forest areas
and a windy exposed site will be better suited to coastal plants. Native
plants have a natural advantage as they are genetically predisposed to have low
water needs once established. Planting our unique and beautiful flora saves
water. Natives are very versatile and
there is one to suit every situation.
They have the added benefit of combining aesthetics with ecological
integrity. Plants
indigenous to our local region are very useful as they cope with local soil and
environmental conditions including heavy frosts in winter and high summer
temperatures and water restrictions. You
may have noted a sense of unity found in many natural and traditional
gardenscapes of Japan, Italy and England, for example. Though each style is profoundly different,
the common element that creates harmony is the use of plants indigenous to a
particular region. An indigenous garden also eliminates the risk of
exotics and artificial hybrids invading the natural environment, polluting the
local gene pool, or providing a haphazard mix of nutrients to the soil. Exotic lawns, bedding plants and artificial
hybrids are not sustainable as they require excessive water, fertilisers that
are high in phosphorus and fungicides, herbicides and pesticides - these
chemicals can contaminate soils and waterways and poison wildlife. Most Australian natives have
adapted to infertile, low-phosphorus soils and only require small applications
of low-phosphorus fertiliser or none at all.
There are many beautiful, unusual, easy care indigenous plants that are
perfectly adapted to climate and fluctuating rain levels. Gardens that do not require huge resources to
maintain (such as large lawns that require mowing, vast quantities of water and
fertiliser) are sustainable in the future. Plant selection should be based on the
plants’ ability to adapt to the site and the aesthetic effect desired including
the ultimate size, colour, and texture of the plants at maturity. Selection should also consider the function
of the area they are to inhabit. This
will ensure that plants cope with, for example, foot traffic or kids and
animals playing. Plants grow best in soils they are
suited to. Find out what grows best in
your area and where it grows best (including soil type and position). This will ensure that a garden or rural
holding is enhanced without the necessity for huge quantities of additional
water after the establishment stage. Incorporating Flora for Fauna, or species
that will attract a spectrum of native birds (and drive out undesirable birds)
and other wildlife has a number of benefits.
It will not only enliven the space but can help keep insect pests at
bay, thus reducing the need for, costs and hazards of toxic pesticides. Maintaining ecological integrity using Flora
for Fauna helps keep threatened species from extinction by providing habitat
and natural food sources and provides a myriad of experiences in your backyard.
Plant selection
should be based on the ability of particular plants to adapt to your garden or
rural environment as well as the effect you are trying to achieve, including
size, colour and texture. Grouping
plants with similar soil, sun and water needs makes it easier to water your
garden. Plants should also be arranged
in accordance with their respective water needs. Grouping plants together with similar water
needs is called ‘hydrozoning’. Remember
that plants are only drought tolerant once fully mature and will only be water
wise if planted in an appropriate site. Always include
understorey plants (grasses, sedges, rushes, lilies, shrubs) as these provide
food and shelter for native fauna, can assist in retarding fire and shade out
weeds. Planting smaller
sized plants (cells or tubes rather than pots) is advisable as the smaller
plants establish stronger root systems and have lesser chance of transplant
shock than larger plants - they will quickly grow to the same size as a larger
plant. Smaller sized plants also require
less resource to grow, so you not only save money but also reduce the carbon
footprint during production.
