topsoil — native garden soil(variable)

Prepare the site by digging a trench approximately 12 to 18 inches wide and 12 inches deep.

Tip: Place the excavated soil on one side of the trench to keep it available for filling later.

If the soil is compacted, use a spading-fork to break up the exposed subsoil at the bottom of the trench.

Tip: Breaking the subsoil allows for better decomposition and air flow.

Fill the trench with organic materials such as sods, manure, and weeds.

Tip: These materials are best buried in a trench to ensure they decay properly to form plant food.

Turn the soil over, placing the organic matter at the bottom so the soil is effectively turned bottom-up.

Tip: Maintaining a consistent trench during digging makes the process more efficient.

Fill the remaining space with the topsoil previously set aside.

Tip: Tamp the soil down firmly to ensure the organic matter is fully covered.

Trenching is the most effective way to bury weeds and sods so they decay into nutrient-rich plant food.
Always keep your excavated soil organized to make the final filling process faster.
