This is a quick little tree ring we did this morning with some blocks left over from a job last year. Finally decided to start selling all the extra pallets I had left over from last year. Will start on the border of the landscape beds on Monday, not sure which block we will use.....I am sure I will have to make a few adjustments to the tree ring, but all and all, 30 mins with 4 extra hands and a B.S. Level did the job. I have been riding around with 45 of those garden blocks in my truck for about two weeks, and was finally able to sell them. $12.50 per block btw.....
