Lasagna Gardening

 

Lasagna gardening is way to turn a lawn or even a parking lot into a field of food. Rather than digging down to prepare the soil, you build the soil up. The style gets its name because of the layers used to build the soil.

Here is a quick step by step on how we used the lasagna approach:

 

1,.Get to know the land and plan the beds--Think about what you want to grow and what sort of space they will take up (for instance squash will sprawl, while basil will stay put) and then plan the beds accordingly. Almost all vegetables like full sun so try to find the sunniest patches of the space and make those your future beds (take some time to get to know the land at different times of day). Next, draw the outlines of the beds with flour (or with sticks or whatever else--flour is bright and biodegradable).

 

2. Adding the layers--the first layer to be added is cardboard or newspaper. This will kill off the weeds and grass underneath by keeping away the light and air. Then begin to put down layers of compost, straw, manure, leaves, coyer*, and more compost (the more compost you can get into the soil the better). At FoodShare we used a mixture of compost and coyer as our top layer, but you could also use straw or leaves. Use what you have access to: if you have sawdust, barn litter, grass clippings, or some other input you think might work, try it, it will probably will work well.

 

  • coyer is the husk of coconuts. It comes from far away, but it is a waste product and is continually being generated. It takes the place of peat moss, which is slow growing and its harvest does bad things for wetlands. Recently, we heard about using grain chaff as an alternative to peat and coyer, so we will be experimenting with this this year as a local waste product.

 

 

3. Water it--a lot of the materials, like straw and leaves, will go in dry and will soak up moisture from the other layers. Give it lots of water initially, this will help all the layers start to break down and it will also mean if you plant right away that it will be a good environment for germinating.

4. Plant right away or let it bake--you can build the lasagna in spring and plant the beds the same day you build the soil. You can also build the beds in the fall and let them compost down (bake) over winter.

 

About the name ...

A woman named Patricia Lanza came up with this approach to gardening and wrote a great book on it called "Lasagna Gardening" her whole philosophy is to make organic gardening accessible to everyone and to just get started and learn as you go.
