I spent most of 3/29/03 replacing the rock garden in the center of my front lawn. The original rock garden had four bushes and a 60' tree. The tree died and had to be removed, the four bushes became three and then the three bushes died. The landscape barrier had deterorated to the point that weeds were the only thing that grew in the bed.
Since this is my first major landscaping project I made the early decision to replicate the original bed.
I reused 80% of the original lava rocks (a potential mistake) I purchased a flat shovel (for shifting items), four bushes, landscape barrier and 3.5 Cubic feet of new lava rocks. Used pointy shovel to dig holes, recycle bins and buckets to hold Lava Rocks.
