Lasagna gardening is the process of using layers of old newspaper, corrugated cardboard, leaves and mulch to create a garden bed. Lasagna gardening allows you to create a garden right on top of existing sod, thereby reducing the size of your lawn.
Reducing the size of a lawn saves water, reduces the need for harmful chemicals and reduces the amount of time spent mowing, which cuts down on air pollution. But a lasagna garden has its own benefits: it wards off pests and weeds without chemicals and helps conserve every drop of moisture.
Building a Lasagna Garden:
Lasagna gardening is a technique developed by Patricia Lanza. Here are the steps, taken from her book Lasagna Gardening which was published in 1998:
You can plant fall-built lasagna gardens right away, let them "cook" first, or just leave them to break down naturally over winter for spring planting.
"Cooking" your lasagna garden is the process of covering the pile with black plastic and weighing it down with bricks or stones. The plastic traps the suns warmth and helps break down the "lasagna" quicker.
**Note: Just in case you are thinking of waiting until after Christmas and using your Christmas wrapping paper for the layers of your lasagna garden instead of newspaper, I checked several sources online and they all said that you shouldn't compost wrapping paper because of the unknown paper content and possibility of harmful dyes.
