Making A Lasagna Gardening Bed
Why lasagna gardening bed for your garden? Well, simply because there is less effort in making one! You do not have to work on the substrate. No tilling or double digging is required. Existing weeds will not be much of a problem as the materials you put on top will prevent them from sprouting. The compost or “soil” you build will be easy to work on because they are loose and easily breaks-up. No frequent watering is needed, the compost is better than garden soil in terms of water retention. And lastly, you do not need to add fertilizers. What can be more nutrient rich than layers of organic compost?
Let me share with you some knowledge that provides an advantage before starting your lasagna gardening beds. Let’s begin by taking notes on some good points. You have to remember that lasagna gardening bed is a raised bed and their edges may be washed away during heavy rain especially if you are making small beds. You need to provide them with edging to keep everything in the bed. Shred or chop the materials that you will be putting to prevent them from matting together. The material you put should create air pockets and space for water to move through. To absorb and retain the water, include soil or compost in your materials. As time passes by, your lasagna bed will drop in volume as the organic materials breaks down. You need to continue adding shredded materials like leaves and cardboard. Keeping these in mind will help you create a productive lasagna bed.
Now, to start with, find a good location to build your lasagna bed and spread cardboard sheets or thick layers of newspaper on the area of the bed. Don’t worry about the grass or weeds underneath, the layers of cardboard or newspaper will suppress them. This dark space will also attract worms that will help convert the waste materials into soil. Spray water to the covered area to keep them in place.
The next layer to put are dried leaves or shredded papers. Spread them (about 6 inches thick) evenly across the bed followed by a layer of your green materials like kitchen wastes and grass trimmings. Do this layering several times until your lasagna bed is about a couple of feet high. This is not an exact science, what is important is to layer your “browns” and “greens” alternately. Avoid placing food wastes like meat products and used cooking oil including pet droppings. Not Good!
Come planting time, simply dig down (right through the first brown layer) into the bed, place your seedlings and add a thin layer of mulch on top to protect them from too much heat.
