Hi all, I'm in the process of planning my food forrest on my new property. It's in the Mary Vally, QLD, Australia. The climate is sub-tropic. I am hoping to establish a food garden that needs no irrigation. I'm only going to be on the property on weekends and the garden needs to be able to look after itself. So I read a lot about hugelkultures and I very much like it. BUT - do I need to worry about the heat that gets generated inside the decomposing hugel? It seems that huegelkultures are a great way to grow in countries that get frost. But what about the sub-tropics? Will the temperatures in my pile start to cook the roots of my plants? I'm thinking to plant most of my fruit trees in hugels. Has anyone done it in my climate zone?
