Lasagna Composting: Sheet Mulching for Soil Building and Sod Removal

Lasagna gardening (sheet mulching) applies the culinary lasagna principle to soil building: layer quality ingredients, get fabulous results. This method works for starting compost piles, naturally removing sod, preparing seed beds, or building berms.

Lasagna Composting Basics

Simplest application: compost pile. Layer nitrogen (greens) and carbon (browns) in a sunny spot. Spread soil between layers for moisture retention and microbial inoculation. Keep moderately moist, turn frequently to accelerate breakdown.

Sod Layering for Garden Bed Creation

Plan 5+ months before planting. Gather carbon (leaves, straw, hay) and nitrogen (grass clippings, kitchen scraps) sources.

How to Layer Sod

1. Flip sod upside down.
2. Cover with wet newspaper (or saturated cardboard—remove tape, avoid waxed).
3. Add nitrogen layer (leaves + soil/compost).
4. Cover with more soil.
5. Add carbon-rich layer.
6. Repeat: ~1 inch per layer, 18+ inches total height.
7. Optional: weight black plastic over top to retain heat. Monitor moisture.
8. In 5-6 months: turn, till, plant.

Newspaper/cardboard blocks grass regrowth. Layer order flexible except: first layer = newspaper/cardboard, last layer = carbon. This method transforms lawn into fertile beds without digging.
