Several ways to plant a Peace Pole
1) One way is to install a peace pole is to dig a posthole two feet deep, set the peace pole in it, and pack the earth back in around it. Clicking this link will take you to a page that further describes that, including a video on how to use a posthole digger. This will work for metal and stone peace poles as well as wooden ones.
2) The most common way of planting peace poles of all types is to dig a posthole, as above, set gravel in the bottom, set the peace pole in the hole and then pour cement in around it. This is the most stable and durable option, but depending on what your peace pole is made out of, might not be the best option.
For peace poles that can last centuries, like metal or stone peace poles, is there a chance that landscaping plans might change someday requiring that the peace pole be moved? Could a nearby building have an addition added that might crowd it. A peace pole in cement might have to be destroyed to move it in a hundred years, whereas one set in tamped earth can be moved over and over again.
3) A third planting method, for wood peace poles only, that does not require digging a hole is to use a steel stand that is hammered into the ground as shown below. They are under $30 at Home Depot (get the longest one) in the lumber area since normally they are used for mailbox and wooden fence installation. The installation can be part of the ceremony with each person getting to swing the hammer driving it in.
- Insert a piece of wood the same size as the pole.
- Pound the stand into the ground.
- Insert the peace pole.
- Tighten the bolts to secure it.
While you are at Home Depot, get the $3.00 level they sell specifically for fence posts. It'll make that part of this job easier when you are repeatedly checking to see if it is remaining vertical as it is pounded into the ground.
