I love the idea of a food forest as a perennial food source, with hopefully a lot less work that the annual veggie patch. I was turned onto the concept some years ago by Geoff Lawton's DVD and ever since, I've wanted to try it. I did a small scale version when we lived in Sydney but I was keen for a greater variety of trees, so when we moved here, it was one of the first things we started. I've been showing you updates on the swales as we've gone along, but since I've got the irrigation in, things have really taken off (surprise, surprise, trees need more than an occasional bucket of water, but in my defence, those buckets get bloody heavy). So now with my trusty 18mm hose, its on.
