Fixing bender board and adding Tan Bark

I the front of my house there is a planter around a tree, it has not been looking good recently, so I am going to fix that.  Below is a photo of the original planter and as you can see currently.

The first step of the project is to remove the old 1 inch thick bender board. It will eventually be replaced by 1/2 inch thick bender board, we are basically making a semi circle and the 1 inch board is to thick that is why it broke, the radius is too tight for the board to make that is why I switched over to the 1/2 inch board because it can handle the tight radius of the semi circle. Once you have it taken out you can move it to the side and move on with the project.

The second step is to remove any routs that are in that are in the path.  This saw is not really meant to be used in the garden but I did not have a curved garden blade. Also if you are replacing the old bender board then you should be able to just lay it down in the old path and put new stakes down.  After you have it where you generally want it, you can nail it to the front board and then place a stake in the center of the curve and then move out ward to secure the whole curve.  The stakes can be made of anything and you don't have to buy them, I make mine out of some treated wood that is designs not to rot, redwood is also a good alternative. If you make your own you should make the angles between 10-20 degrees.

Now the new board is added and the project is complete, the only thing left to scoop any exes dirt from around the project and moisten the dirt with some water. Now it takes about 3 cubic feet of tan bark to cover the semi circle.  You do not need to buy a dump truck full of tan bark if you are just doing a small project but if you are going any projects bigger than 20 cubic feet of material it makes more sense to go a landscape yard and rent a truck because it is usually much more cost effective.
