Are cardboard boxes safe for sheet mulching, specifically the tape and ink? The industry standard for ink on boxes is soy based, so these boxes are completely safe. Sheet mulch sections completely with cardboard, compost and mulch If you don't have enough materials or people power to sheet mulch your entire lawn in one day, we recommend breaking it up into smaller sections and completely sheet mulching one section at a time.
Ideally, the plant should sit slightly above the mulch layer. Keep mulch away from the stems and roots of trees, you don't want mulch volcanoes! Don't sheet mulch with landscape cloth : It does not breakdown and does nothing to feed your soil. On the other hand, cardboard decomposes and adds carbon naturally to your soil. I have found that most plants will live with onion weed, so I just methodically remove the biggest ones every spring, until the outbreak is under control.
Hi Zooey. We use newspapers that use soy-based ink. You can call and ask your local newspaper what type of ink they use to clarify. Hi Dylan, A range of places. Basic HTML is allowed.

Sheet mulching is used to smother the ground with organic matter generally cardboard, newspaper and woodchips plus some nitrogen materials including animal manures or blood and bone , usually to suppress grass in order to establish more desired plants.
The desired plants are planted directly into the original soil through the sheet mulching with some compost if needed. No-dig gardening also smothers the ground, however has many more layers of organic matter to create an instant raised garden bed which you can plant into the same day you make it.
Righteo, lets start. Materials can also be purchased. Corrugated cardboard in large, wide rolls; a loosely woven burlap fabric made for landscape purposes, and finished all-green compost.
Water the area well before you plan to start the process. Plants growing on the site will need to be cut to the ground. Roots of most weedy plants can be left in the ground, but woody stumps or pieces should be removed. A dryed-out lawn can be left in place; sheet mulch right over it.
This is a great opportunity to amend your soil, and increase its fertility with an array of micronutrients. Acid soils can be sprinkled with lime; alkaline soils will be improved with a little gypsum or sulfur. Bonemeal and rock phosphate will supply phosphorus, which is essential for root formation, early growth and good seed formation. Kelp meal, greensand, or rock dust all add trace minerals. If the area is compacted, or you are dealing with clay, take the time to open it up just a bit before you start to mulch.
Simply push a fork or spade into the ground and rock it back and forth to open up holes in the ground. Turning disrupts the soil ecology; so that is a bit of hard work that is best avoided!
One of the very best amendments to apply is rock dust; simply sprinkle it liberally over the area. Apply a thin layer of nitrogen rich materials; this can be fresh grass clippings, finished compost, blood or cottonseed meal. This layer will attract the earthworms, burrowing beetles and other invertebrates which will help loosen the soil.
Cover the area with about one quarter inch thick layers of newspaper. Avoid using the glossy pages from the paper, and remove the staples and tape from the cardboard.
Overlap the edges by three to four inches, and wet everything down as you work. The purpose of the paper is to create a light blocking layer that will smother the weeds; an added benefit is that the worms also love the darkness and moisture that the paper creates. Basically I was saying why not improve the base soil rather than using effort and imported resources to create new soil.
I hope you can see that food gardening without sheet mulching is very possible. Our last 2 day biodynamic food growing workshop for in Brisbane is on Nov Come along, you will enjoy it, the practical insights above are demonstrated in my gardens where we host the workshop.

A well presented argument but based on a false statement at point 1. It creates compost under the sheet and adds to it above the sheet eventually creating a rich environment. Your comment about your friend having great soil already ignores the fact the he is still creating better soil. As for washing away in the rain…. Seriously Peter. I have built a beautiful 6 inch depth of soil on clay with nothing other than weeds, animal manure and mulch.
Love your posts which I hope make people think beyond what they read on the internet and think for themselves. Mark Thanks for the compliments, yes I do feel like a provcateur at times, started that way when I was a child and now I am Like to respond on your points.
Remove organic matter — the sheet mulching kills off the weeds and grass.
