If you wish to flip a barren lot right into a permaculture paradise, you’ve obtained to begin from the bottom up — and sheet mulching is a straightforward technique to begin. You begin with a biodegradable weed barrier like cardboard, and from there construct a thick, layered substrate in your backyard with compost and mulch. Because the supplies break down, worms transfer in, softening the soil under, and making a wholesome, aerated planting mattress.
Listed below are some easy steps that can assist you get began with sheet mulching your self.
The next is an excerpt is from Perennial Greens by Eric Toensmeier. It has been tailored for the online.

Sheet mulching combines soil enchancment, weed removing, and long-term mulching in a single fell swoop. This method, often known as lasagna gardening, can construct exceptional soils in only a few years. There are a number of key elements. First, a weed barrier like cardboard is laid all the way down to smother weeds. In concept (and very often in follow) the cardboard decomposes after the weeds have all died and become compost. The second ingredient is so as to add compost, or construct a layered compost pile that may enrich your new backyard mattress. The third step is so as to add a thick layer of mulch on prime, to maintain new weeds from getting established.
I’ve had nice outcomes with sheet mulching, though generally the primary 12 months is a bit tough on delicate species, till the uncooked supplies break down. You need to use sheet mulching to show lawns or weedy waste areas into gardens in only a few hours, and even to construct soil from scratch inside constructed frames for raised beds. Sheet mulch can vary from only a few inches thick to 2 toes or extra, relying on how unhealthy your soil is and the way a lot uncooked materials you will have accessible (it’ll prepare dinner down and settle fairly a bit).
9 Easy Steps to Sheet Mulching
Mow or minimize your garden, weeds, or different vegetation proper all the way down to the bottom.
Plant any crops that may require a big planting gap (together with woody vegetation, perennials in giant pots, and enormous transplants).
Add soil amendments (as decided by your soil take a look at).
Water the entire space totally. You will be placing a layer of cardboard or newspaper over it, and rain and irrigation received’t soak via very effectively till that weed barrier breaks down. Water additionally helps the decomposition course of get going.
When you have compost supplies that will include weed seeds (like contemporary manure, leaves, or hay), unfold them in layers on the bottom.
Put a dry, carbonaceous layer of hay or shredded leaves under any manure layer. Keep away from thick layers, and ensure to get carbon-to-nitrogen ratio simply as in the event you had been constructing a compost pile. Water this layer effectively.
Lay down a weed barrier. I choose to make use of giant sheets of cardboard from equipment shops, as a result of these last more and are faster to lie down. You need to use layers of moist newspaper too. Be sure to have a 4- to 6-inch overlap the place sheets meet so buried weeds can’t discover a path to the floor. When you have already planted crops, or produce other preexisting vegetation, don’t mulch over them. Minimize holes within the cardboard to make some respiratory area for every plant (or go away some room round every plant when laying newspaper).
Now you possibly can add your weed-free natural supplies. I prefer to hold it easy, and simply add a pleasant layer of compost. You may as well do some sheet composting right here, alternating layers of nitrogen-rich supplies like contemporary grass clippings with carbonaceous supplies like weed-free straw.
Now you add your ultimate prime mulch layer, at the very least 3 inches thick. Water the entire mattress totally as soon as once more. Your sheet mulch mattress is full.
You possibly can plant proper into your mattress in the event you like. To plant tubers or potted vegetation, simply pull again the highest layers till you get to the weed barrier. Minimize an X within the cardboard or newspaper. If you’re transplanting a big plant, peel again the corners of the X. Throw a double handful of compost within the planting gap after which put within the plant. Pull the layers and prime mulch again across the plant, water effectively, and also you’re all set. Planting seeds is simple too. Simply pull again the highest mulch to the compost layer and plant your seeds. It’s possible you’ll wish to minimize via the weed barrier under first, relying on weed stress under the barrier. If you’re planting seeds, you’ll want to water commonly, as compost on prime of cardboard can dry out rapidly.
Sheet mulch will be so simple as three layers: cardboard, compost, and straw. However compost isn’t low-cost, and it may be enjoyable and thrifty so as to add layers of natural supplies that may break all the way down to make compost on their very own. When doing so, you wish to alternate layers of high-nitrogen materials (greens) with high-carbon materials (browns), similar to the recipe you utilize to construct an unusual compost pile.
You wish to have extra carbon supplies than nitrogen: the perfect ratio by weight is 30:1 carbon to nitrogen, which interprets roughly to 2 to a few occasions as a lot carbon bulk as nitrogen. Preserve these layers skinny (3 inches at most) and they’ll break down extra rapidly. Some gadgets ought to be shredded first—leaves as a result of they mat, and enormous gadgets like cornstalks in order that they break down extra rapidly. Keep in mind additionally that some supplies should be stored under the foundation barrier as a result of they might include viable seeds.
