From the picture, you can notice that there are 3 layers of Fences available. The Fences will consist of 2 Ft Wide & 1.5 Ft Depth. The Open Spaces will consist of 3 Ft Wide. Either we can plant ourselves in the Open Spaces or we will allow nature to take care of itself.
It is not necessary to have all the 3 layers of the Fences. Depending on the requirement, you can go for single layer or multiple layers of the Fences.
