How to Select the Right Plant

Plants are sensitive to the amount of sun and water they receive, the temperature, and the type of soil. When selecting plants it is essential to know the microclimates and soils across your site and choose plants which like those conditions. Failure to do so can be costly, as poorly selected plants usually die or have weak growth and few flowers.

Step 1 – Assess site conditions

Draw a sketch of your site showing its microclimates, environments and soil types

♦ What is your local climate?

climatezonesInland – hot summers
Eg Mallee, Wimmera, North Country, Horsham, Mildura, Swan Hill, Echuca, Bendigo, Shepparton, Albury/Wodonga

Highlands – frosty winters
Eg Hamilton, Ararat, Ballarat, Kyneton, Kilmore, Mansfield, Bright, Wangaratta

Coastal – temperate
Eg Warrnambool, Geelong, Melbourne (most), LaTrobe Valley, Sale, East Gippsland

♦ What are the microclimates and environments across your site?

NOTE: Microclimates and environments can change dramatically even across small suburban gardens. (For example: exposed north or west facing sites are generally hot and dry; a southerly aspect cool and moist; buildings can create windy spots or channel cold, frosty air in winter).

Temperature: hot, normal, cold

Frost: frost free, light (-2 to -3°C), moderate (-4 to -5°C), heavy (> -6°C)

Light: full sun, part sun, full shade

Environment: salt spray, windy, bushfire prone area

Soil moisture: dry, normal, moist, waterlogged

♦ What soils do you have on your site?

NOTE: Soils too can change dramatically across small sites. (For example: clay sub soil might have been deposited on the top soil in a section of the site during building construction; limestone might occur in a location making the soil there alkaline)

>> Information About Soils

Type: Gravel, sand, sandy loam, loam, clay loam or clay

pH: Alkaline (pH greater than 7.4), neutral (pH 6.6 – 7.3) acid (pH less than 6.5)

Step 2 – Select plants which suit both your garden design and site conditions

Now it’s time to visit your local plant nursery. Take your site sketch with you and always read the plant labels to ensure the ones you like suit your site conditions and, when they reach maturity, will have the right size and shape.

NOTE: Most Australian native plants grow rapidly, so it is often best to buy a small plant instead of a more expensive mature plant.
