I am fairly new to permaculture and I have been setting up a Aquaculture/Aquaponics setup along with raised bed vegetable gardens on one side the other side of my yard I am doing Permaculture/ Forest garden. The space for the forest garden is about 35X35 feet and I currently have 4 fruit trees/ 1 peach - 2 apples - and 1 orange, planted about 20 feet apart from each other with artichokes, asparagus, raspberries, blackberries, and grape vines planted along the perimeter of the fence.
I have that prairie clay soil, but there is no organic matter or rocks in it. So when it is wet it is like glue. In the areas that I have planted I have mixed in compost.
What else can I include in this design, if you want to call it that. And how should it be laid out? I want non-stop food production and easy maintenance, if that is possible.
