I keep forgetting who is where in this huge continent. Maybe a thread dedicated would help.
I am in South West Victoria, with a garden at Penshurst (between Warrnambool and Hamilton) and one in Casterton (between Hamilton and Mt Gambier) The Penshurst garden is rocky, as it’s on the side of Mt Rouse, a dormant volcano. We have seams of scoria (quarried out of Mt Rouse, that’s how much there is) but the soil is actually rather good. But there are giant rocks buried too, so when you are digging you occasionally clang. And it’s difficult to actually run a fence straight with posts at even intervals.
At Casterton I am on the flood plain, although in town. So I have lovely river silt to work with. Which goes under water every few years. The last flood that got under the house (which is 1.4m off the ground to mitigate the effects) was in 1996. But the weather is hotter in Casterton than in Penshurst.
