Planting trees above ground
I have clay soil and was wanting to try to plant a 4-5” Tulip Poplar in my front lawn which has low spots and retains water. Instead of digging a whole in the ground, I was hoping to build the area by laying fabric weed control directly on the grass then place wet layers of cardboard on top of that followed by a foot or more of good garden mix and plant the tree directly in the soil. Will this work??? I will be spreading the soil evenly, this picture is just showing how i start.
