How to Fix Clay Soil in a Yard

Overview

The very nature of clay soil--sticky, heavy and compact--makes it very difficult for anything to grow. Roots can't penetrate clay soil and air can't flow through it. There are different ways of fixing clay soil in a yard and all of them require adding large amounts of organic material. Wait until the clay soil is dry before working it and use 2 to 3 cubic yards of organic material or other amendments for every 100 square feet of gardening area. Begin this process in the fall.

Step 1

Till the soil to a depth of 12 inches, turning over the soil as you go and crushing any large clumps of dirt. Remove any rocks, roots or other debris.

Step 2

Add a 6-inch layer of coarse builder's sand and a 2-inch layer of compost over soil. Use your garden fork to mix the materials together.

Step 3

Rake the area until it is level.

Step 4

Spread a 6-inch layer of wood chips or shredded pine bark over the top of the soil and water deeply.

Step 5

Wait until spring and then mix the wood mulch into the soil and you are ready to plant.
