Laying gravel on uneven ground
Hi, I am creating a gravel garden. I have dug out 4 inches of soil to prepare the ground area for gravel. I was wondering if I need the ground to be completely even before laying the gravel? The problem is the ground is so hard (clay content) that I can not wake the area. My friend suggested I buy some bags of top soil to spread across the area which I can then go over with a wake. Is this really needed?
