Why You Should Remove Grass Before Adding Soil to a Bed

Landscapers sometimes place new soil over existing grass, but this creates long-term problems.

Problems with Buried Grass

• Decomposing grass ties up nitrogen, starving new plants.
• Aggressive grasses (e.g., quackgrass) can regrow through the new soil.
• Root penetration is hindered by the dense sod layer.

What to Do

Insist the landscaper remove the sod before adding soil. If they’ve already finished, monitor for nutrient deficiency and invasive grass shoots. Top-dress with nitrogen-rich fertilizer if needed.
