Lasagna gardening, also known as \u201csheet composting,\u201d is a simple, no-dig method for turning grassy or weedy spaces into productive garden beds. By layering cardboard or newspaper with organic materials such as leaves, compost, and grass clippings, this method suppresses weeds while building nutrient-rich soil. Over time, the layers decompose, creating fertile ground ready for planting without the need for tilling or strenuous digging.<\/p>\n
As a child, I remember watching my mom start a new garden. She was adding a vegetable garden space on top of the hill at my grandparents\u2019 house. She began by laying down cardboard. She placed flattened pieces of cardboard and newspaper on top of the lawn in the shape she wanted her new garden to be. She explained that this would snuff out the grass and eventually the paper would break down. She laid wooden logs around the edges of the cardboard. Then she added some old mulch and old leaves and shoveled dirt over that in a thick layer. That\u2019s it, it was that simple! Mom didn\u2019t have a name for the method back then but it\u2019s what I now know as the \u201clasagna gardening\u201d method.<\/p>\n
Lasagna gardening, also sometimes referred to as \u201csheet composting,\u201d is a cost-effective, no-dig way to turn a weedy or grassy space into a garden. Because you aren\u2019t tilling soil and removing the grass and weeds by hand, it\u2019s much easier on the body.<\/p>\n
The idea is that you snuff out the growth below the paper layer, then add organic materials that will eventually break down, top with soil (if you want), and you\u2019re ready to go. The paper will eventually decompose, as well as the organic matter, offering nutrients to the soil below.<\/p>\n
Ideally, you\u2019d prep your garden in the fall using fall garden clean-up, such as fallen leaves and twigs, in your layering. By spring, the garden will be ready for planting. If you want to speed up the process, garden soil can be added in a thick final layer and planted directly into.<\/p>\n

Select a flat or gently sloped area with good sunlight. Mow any tall grass if necessary.<\/p>\n<\/li>\n
Plan the size and shape of your garden. If desired, line the edges with logs, rocks, or garden bed frames to contain layers.<\/p>\n<\/li>\n
Cover the ground with cardboard or multiple layers of newspaper. Overlap the edges to prevent weeds from sneaking through. Remove any tape or glossy sections.<\/p>\n<\/li>\n
Layer shredded leaves, straw, sawdust, twigs, or mulch on top of the paper. These materials provide carbon and structure to the bed.<\/p>\n<\/li>\n
Spread grass clippings, compost, food scraps, or coffee grounds. These materials supply nitrogen, essential for plant growth.<\/p>\n<\/li>\n
Alternate brown and green layers until the bed reaches the desired height, typically 12\u201318 inches. Only one base layer of cardboard or paper is needed.<\/p>\n<\/li>\n
Lightly water each layer as you build the bed to help materials settle and start the decomposition process.<\/p>\n<\/li>\n
Add garden soil or compost on top if you want to plant immediately. Otherwise, allow the layers to break down naturally over the fall and winter.<\/p>\n<\/li>\n
Once the bed has settled, you can plant directly into the top layer. Root crops, vegetables, and annual flowers all thrive in lasagna gardens.<\/p>\n<\/li>\n<\/ol>\nTips for a Successful Lasagna Garden<\/h2>\n
