First I placed some hay on the ground to help serve as a weed barrier and it will compost and add to the soil. Then I laid out four bricks in a square that measured one foot square and filled in the rest of the shape to form the spiral.
Once you have the initial shape it is simply a matter of continuing to stack the brick to build the walls. You can start in the middle and build that area up first to get to the height that you want and then finish the walls. As you finish the outside walls, you will want them to taper down allowing sunlight into different areas of the spiral. By doing this you are creating microclimates for various plants.

It took about 3-4 hours to rake and clear the area and then to build the spiral. I have put some old hay in the spiral that has already begun to compost and will finish it with some fresh straw. Once the new straw is in, all I have to do is move the hay aside to place a couple of good handfuls of soil in a hole and put the plant in place. The idea is that the plants will get the the nutrients that they need from the soil and the roots can spread out into the hay in search of water. As the hay composts I can add more until eventually the entire spiral will be full of soil. I would like to build some more with stone just because I think they look prettier. You also don't have to build them this tall but since I was working with brick I knew this was out it would turn out. Here's a picture of the final product.
If you look on You Tube you can find some videos of various spiral gardens and how they were made. I will put a picture up when I get all of the plants in so you can see how it looks. In the meantime, happy planting!
