Rehabilitating Compacted Clay for Tree Planting: A Complete Soil Restoration Protocol

Builder-compacted subsoil requires mimicking centuries of soil development in a weekend. The investment pays off in tree survival and growth.

Step-by-Step Restoration

Wide tilling: Rent a rear-tine tiller; pulverize clay in a 10-foot circle per tree.
Amend thoroughly: Mix 2-3 bags soil conditioner (Nature's Helper, Clay Cutter) per tree into tilled area.
Add nutrients: Incorporate 1 pint lime and ¼ cup 0-46-0 (superphosphate) per tree.
Inoculate with mycorrhizae: Beneficial fungi enhance root function; source from specialty suppliers.
Install drainage: Dig 2-foot-deep dry well at low edge of planting area, fill with 18 inches coarse gravel, cover with landscape fabric, backfill with topsoil.

Your trees will establish faster and withstand drought better in this reconstructed soil environment.
