My Lasagna Garden Technique Using 4 Truck Loads of Recycled Cardboard

14 ft x 28 ft garden, cardboard cover the whole area, I used raised beds, 4 truck loads of recycled cardboard from a dumpster
While it is an organic gardening technique, it differs from traditional gardening approaches by using a form of sheet composting. These layers in the sheet compost are built up in a manner like making lasagna. By building up these layers of organic material over a period of months and years you create a soil mixture that is incredibly rich in nutrients, and because of the close plant spacing and natural mulching from the layers the effort is lower because of fewer weeds and less need for water.
Building a Lasagna Garden –Don’t bother to remove the grass or sod in the area. If needed define the area with a string or a hose laid out in the shape of the garden.Cover the area with wet newspapers, taking care to have the edges overlap to act as a mulch over the previous growth. Use a thickness of at least five sheets.Cover your layer of newspapers with an organic layer, most often peat moss is used for this first layer. A thickness of one to two inches should suffice.Add to that another layer of several inches of organic matter or compost. Then alternate layers of peat moss and organic matter until you have built up a bed that is at the desired depth.Add water to the bed until you achieve a moisture content that gives the bed the consistency of a damp sponge
From here you start your plantings. Depending on the state of decomposition of the organic material added to the bed, it may be advisable to wait and let the bed “work” to decompose the organic material further, to avoid robbing the nitrogen from the soil.
The spacings of your plantings are along the lines of most intensive bed gardening techniques, where the space for rows is eliminated in the beds, and access is gained from the edge of the beds.
Advantages of Lasagna Gardening – There are a handful of advantages to lasagna gardening:Reduced water needs – controlled drainage since it’s basically a raised bedReduced weeding – Naturally mulched from the addition of organic matter, and the close plant spacing further suppresses the weeds.Reduced maintenance – No tilling or turning, just add a steady stream of organic matter.Improved aeration of the soil – Since there is no foot traffic on the actual bed, the soil is not compressed and the root structure of the plants are free to grow.
You can see that this modification of the raised garden bed approach has a lot going for it, and can be a great help for an area that has very poor soil.

    Don't see where you put any soil for plants. Did you use any or just put cardboard around existing plants shrubs etc ?
