In this corner of Western Australia, black truffles are becoming big business. Although the soil requires quite a bit of lime to bring up the pH, they are growing exceptionally well here, with some of the biggest specimens in the world coming from a farm about 20 kilometers away from me. I have a small plantation of innoculated oaks and hazelnuts that are years away from providing a harvest, but I live in hope. This is an example of a truffle that I purchased locally. It cost around $100.
