Stone, when we originally had the designer come out, there was rock completely encircling the tree. We had the standard patchy grass and dirt under the cedar overhang. The designer said the all the rocks were too heavy for the tree and suggested removing half the rocks and adding in the chips. In addition, we took out about 4 feet of the patchy grass. Since it looked horrible when it was first completed, they added in the planting area next to the grass to give us some planting options. The plastic barrier is only staying for the next 2 weeks and is there to keep the dog off the newly seeded grass.
Frillylily, you are partially correct on the why they did the chips. The other part was due to our dog. He runs around like a Tasmanian Devil and his favorite path is right where the chips are. He does love the softness of the chips, and I have to admit they smell wonderful. To answer your other question, we will be retiring soon and do have young grandchildren. There is no great place in our yard for a separate area for the dog. He likes to be outside enjoying the yard and I would like to be able to accommodate him in the overall design.
