Turn Poor Soil into a Thriving Garden with Sheet Mulching 6

Lasagna gardening — sometimes called sheet mulching — is an easy method for building a garden bed with little work.

When we first moved here, I wanted to get some plants in the ground right away, but knew that I’d need to improve the soil for better success in the long run.

I’d read about lasagna beds (called such because the beds are layered, much like a lasagna) but had never tried them.

This seemed like a perfect chance to it out.

Lasagna bed gardening is a no-till, no weeding, easy peasy method to get a garden bed in the ground FAST.

Sheet mulching: building the base

I started by raiding my recycle pile. Cardboard boxes, newspapers, and even old catalogs form the base of the lasagna bed.

I covered my planting area with a thick layer of these paper products, overlapping them as I placed them down, and then wet them thoroughly.

This base layer was close to 1/2″ thick.

Note: This is a no-till method of planting. You do not need to work the soil under the lasagna bed. You do not need to pull weeds. The newspaper and cardboard layer will smother any weeds that are there. Score!

Sheet mulching: Adding a layer

My first “green” layer was ginger, which we have in abundance. I’ve used banana stumps here, too.

You probably don’t have those “ingredients” on hand. Essentially you’re looking for something with a high moisture content and high in nitrogen. Vegetable scraps, grass clippings, or fresh manure can work well, too.

Now, must this be the first layer? Not necessarily. You can start with dry leaves or straw and layer a nice high-nitrogen layer on top of that. I start with the ginger (or banana) because it’s so chunky.

This is a very forgiving method! You can use coconut coir here, or peat moss (though there are environmental issues with peat moss), or some sort of locally available organic product that holds moisture well.

Sheet mulching: Layer number three (with a warning)

Layer number three was mulch. I used free mulch from our local green waste center, about 6-8″ deep.

I also used free labor provided by my son. (UPDATE: We had the unfortunate experience of getting a contaminated load of free mulch that killed everything we put it on. I no longer use the free mulch, though I do still use free labor.)

You can use leaf mold or partially decomposed leaves if you don’t have mulch. You could also use rotted straw from a stable, lawn clippings, sawdust, or any combination thereof. Again, I watered the bed down.

Sheet mulching: Final layer

The final layer was store-bought compost. In the future, I’ll have my own compost or composted manure, but at the time store-bought was the best I could do.

The finished lasagna bed sat about 10″ high. Once it was complete, I planted seeds directly into the top layer of compost and watered them in. Days later, I had veggies growing.

As the plants grow, the roots work their way down into the layers of the lasagna bed and the worms work their way up.


The layers decompose, improving the soil while supporting a crop of vegetables. I found that I did need to be judicious about watering, since the lasagna beds didn’t hold moisture as well as a soil bed would have.

Lasagna gardening is flexible

I made my first lasagna beds directly on the ground with no containment. I’ve also used this method in raised beds bounded by big stones. It’s a pretty flexible way of planting.

In a perfect world, I’d have put this lasagna bed together in the fall with more repeating layers and let it sit for several months until time to plant. But let’s face it: It’s not a perfect world and I’m terribly impatient.

As it is, the layers will compost as the seedlings grow. If you’re paying close attention, you’ll see that we doubled the size of the lasagna bed pictured at the top, but I neglected to photograph those stages.

When my vegetables were done producing – about four months later – I pulled them out and dug into the lasagna bed. (I was so curious to see what I’d find!)

While my puny soil was still far from perfect, just about everything I’d layered into the beds was gone.

There were a few remnants and small pieces remaining from some of the cardboard boxes, but that’s it! Everything else had completely disappeared and become part of the earth.

This method is an excellent way to get a jump on garden season, too. Simply follow this method using several layers of material but skip the seeds.

Mother Nature will do her magic during the cold winter months and you’ll have a beautiful bed to start growing in come warm weather.

Lasagna gardening is a great (and easy) way to get started with no-till growing. Use sheet mulching with materials you have on hand for a budget-friendly garden. It's a great way to put your garden to rest at the end of the season, too, as the soil will be improved as it sits. #garden #homestead #growingfood

    This is going to be my method this spring since the land at our new old homestead hasn’t been gardened in a decade or so. The ground is seriously hard packed. We are building our first beds this fall to plant in the spring. I bought the book earlier and was smitten!

    Great fall -winter garden activity. I’m itching to go play in the dirt……

    It is not a perfect world! Glad to see others breaking the rules. 🙂

    Was wondering about the cardboard and chemicals. Some are treated or have dyes, is this an issue? Is there anything I particular to watch for? 🙂

      Ask ten people and you’ll get ten different answers. 😉 I do use pretty much anything in the beds, but I know people who are very particular about which cardboard they’ll use. My thinking is this: If worms can process the pathogens out of manure, they can surely do the same with the ink. And since worms are plentiful, I have to think that the inks/cardboard don’t cause the worms any trouble. Of course, this is a lot of assuming on my part. We’ve each got to do what we’re comfortable with.

        Hi, can I use bamboo instead of ginger or banana?

        • Kris Bordessa Post author

          Bamboo tends to be acidic, so I don’t use a lot of it.
