Drought Tolerant Australian Native Plants For Alkaline Soil

Alkaline soils can be difficult to manage. Most gardening programmes emphasise the use of lime forgetting that many places beyond the east coast of Australia have alkaline soils. This is particularly so in South Australia.

A hint that I was given was to plant in raised beds. As little as 10cm above the surrounding soil will reduce the alkalinity effect. This of course also provides better drainage in heavier soils.

    I live in Denham Western Australia. I was enquiring as to what would be suitable tree speciesto plant. Our PH. Levels are between 7.5 – 9.0 with some clay also present. Any suggestions ? CHeers Jack.

      Your ph is marginally better than ours (about 10 !!!), and many of the lovely WA trees do well here in similar conditions. Depending on height may I recommend Eucalyptus torquata (Coral Gum), E woodardii, E ficifolia (WA flowing Gum). This one comes in a number of colours, the most spectacular being crimson through to tangerine, plus others, Can’t guarantee colour from seed. There are lots of othet small trees suitable for house yards in your state.
