Lasagna garden in raised bed

shlansbergJuly 8, 2010

Hi, I've had a vegetable garden before, but, I am going to plant my first "raised bed" organic veggie garden.

My question is: If you do "lasagna gardening" (layering with newspapers, green and brown materials, top soil, etc.) do I need a composter?

Does the "lasagna garden" method actually become a composter on its own?

Please help. People say you can throw newspaper, and then anything you would throw into a composter (kitchen scraps, etc) and then more newspaper, etc and it will decompose on its own.

Will it smell?

How long does it take to decompose?

Am I better off with a composter?

Confused.... Would LOVE any and all advice.

By the way, I started my seeds indoors. Organic seeds. Evertying is sprouted and ready to go in a bed. My raised bed is made of cedar and redwood -- no treated wood.

Thanks!!! Stephanie

A lasagna bed starts as a "raised" bed but as the organic matter in the pile is digested the height shrinks, so in a raised bed you will want some soil to add that organic matter to. Whether there is any offensive odor depends on what you add to the mix and that will also determine how long it takes to be digested.
Perhaps this from Pat Lanza will help.

Kimmsr - When you say that soil should be added to the organic matter, do you mean that it should all be mixed/layered together at the start of the lasagna.... or is there a different way that is better. Perhaps adding the soil to the bottom, or the top.

If you are building a Lasagna Bed that is one thing but if you are building raised beds that is another. If you want the soil level in a raised bed to stay kind of close to the top of what level you established then soil is necessary. If totally rebuilding your Lasagna Bed annually, and watching the level shrink during the growing season is not a problem then a Lasagna Bed is the way to go.
