Truffle tree Holm Oak (infected with Tuber aestivum)

I watch tv program called My Kitchen Rules Australia someone on the program said they have truffle farm l  thought you go in woods and find truffles with help from the dog. When their father started the farm. I googled I found out you buy truffles trees them Simply plant a truffle tree and sit back and wait for your truffle crop to develop. In optimum conditions, these trees start to produce truffles 4-7 years from planting. I wish I was young !
