6 Best Newspaper Mulch For Suppressing Weeds In Rows On a Tiny Budget
Suppress weeds in garden rows on a tiny budget. This guide details the 6 best newspaper mulching techniques for an effective, low-cost garden solution.
Staring down long rows of freshly planted seedlings can feel like a race against time, with weeds as your main competitor. The cost of landscape fabric or wood chips can quickly eat into a tight budget, leaving many hobby farmers feeling stuck. But the solution to your weed problem is likely already sitting in a recycling bin, waiting to be put to work.

Unlocking Free Weed Control with Newspaper
The simplest solutions are often the most effective. Using newspaper as mulch is a time-tested technique that works by creating a physical barrier, blocking the sunlight that weeds need to germinate and grow. This method, often called sheet mulching, essentially smothers new weeds before they can ever see the sun. It’s a brilliant way to turn a waste product into a valuable garden asset.
Beyond just stopping weeds, a thick layer of newspaper offers several other benefits to your soil. It helps retain moisture by slowing evaporation, which means you’ll water less often. It also insulates the soil, keeping root zones cooler on hot days and warmer on cool nights. As the paper decomposes over the season, it adds valuable carbon to the soil, feeding the earthworms and microbes that create healthy, living dirt.
For row crops, the application is straightforward and efficient. Simply lay down a thick section of newspaper—at least four to six sheets—between your rows, overlapping the edges by a few inches to prevent any gaps. Wet it down thoroughly with a hose to hold it in place and help it conform to the soil. You can then top it with a thin layer of straw, grass clippings, or compost to improve its appearance and speed up decomposition.
Local Broadsheets: The Classic B&W Choice
Your local newspaper is the quintessential material for sheet mulching. It’s readily available, often free from neighbors or community drop-off points, and perfectly suited for the task. The large, unfolded sheets make it easy to cover a lot of ground quickly, which is a huge advantage when you have multiple long rows to tackle.
The key is to stick with the standard black-and-white print pages. Most black ink used in newspapers today is soy-based, making it perfectly safe to break down in your garden soil. Unlike glossy paper, the porous newsprint absorbs water readily and decomposes within a single growing season, adding organic matter directly where your plants need it.
When you lay it down, don’t be shy. A couple of sheets won’t do much against determined weeds like crabgrass. You need a substantial barrier. A good rule of thumb is to create a layer thick enough that you can’t see the soil through it, even when wet. A thickness of 4-8 sheets is the sweet spot for most common garden weeds.
Community Shoppers: Gloss-Free and Abundant
Don’t overlook those free community papers and shoppers that land on your driveway. While they might seem like junk mail, they are often printed on the exact same uncoated newsprint as traditional newspapers. This makes them an excellent, and completely free, resource for mulching your garden rows.
The main advantage here is sheer volume and convenience. These publications are delivered right to you, and you can quickly accumulate a large stack for your project. Their smaller, tabloid-style pages can be easier to handle and fit into tighter spaces between delicate seedlings. Just like with broadsheets, their uncoated paper breaks down beautifully, feeding your soil’s ecosystem.
The one thing to watch for is the type of ad. While most of the paper will be plain newsprint, some may contain a few glossy, full-color inserts. Simply pull these out and recycle them separately. The rest of the paper, with its matte finish and simple black or limited-color ink, is ready to go straight into the garden.
Financial Papers: The Soy-Based Ink Advantage
If you’re particularly concerned about what goes into your soil, financial newspapers are an outstanding choice. Publications like The Wall Street Journal or Financial Times are famous for using high-quality, soy-based inks for their dense, text-heavy pages. This is about as clean as printed paper gets.
Soy-based ink is a superior choice for the garden because it’s derived from a renewable resource and contains far fewer volatile organic compounds (VOCs) than old-school petroleum-based inks. This means you’re not introducing unwanted chemicals into your soil food web. The paper itself is also typically high-quality newsprint that decomposes reliably.
You might not subscribe, but these papers are often available for free at the end of the day from coffee shops, libraries, or offices. Their lack of large, colorful photographs means the pages are almost entirely covered in safe, soy-based black ink. This makes them a top-tier option for the soil-conscious gardener.
Uncoated Packing Paper: A Clean, Ink-Free Option
For those who want a completely ink-free weed barrier, uncoated packing paper is the perfect solution. This is the simple, brown or gray paper used to wrap fragile items or fill voids in shipping boxes. It functions exactly like newspaper but without a single drop of ink, offering total peace of mind.
This option provides a clean, uniform look between your rows and breaks down into pure carbon for your soil. It’s an excellent choice if you’re establishing a new organic garden and want to be absolutely certain about your inputs from day one. The material is porous, allowing water and air to penetrate while still blocking light effectively.
While not always delivered to your door, you can often find it for free. Ask local businesses if you can take the packing materials from their shipments. You can also find huge amounts on community marketplace sites from people who have recently moved. It’s a fantastic way to intercept a useful material before it heads to the landfill.
Phone Book Pages: A Dense, Old-School Barrier
Phone books may be a relic of the past, but if you can get your hands on a stack of old ones, you’ve found mulching gold. The pages are incredibly thin, which might seem counterintuitive, but their density is their greatest strength. You can easily create an incredibly thick, overlapping mat that is nearly impenetrable to weeds.
Because the pages are so fine, they conform perfectly to the contours of the soil, leaving no gaps for stubborn weeds to exploit. A half-inch-thick layer of phone book pages, thoroughly wetted down, creates a formidable barrier that lasts for months. This is a great choice for suppressing particularly aggressive weeds between long-season crops like tomatoes or squash.
Just be sure to prepare them correctly. Tear off the glossy front and back covers and discard them. It’s also best to cut away the thick, glued binding. The thin, matte-finish inner pages are what you’re after.
Cardboard Fluting: The Ultimate Tough Weed Base
When you’re facing down truly tenacious perennial weeds or breaking ground on a new plot, you need to bring in the heavy artillery. That’s where cardboard comes in. Specifically, the corrugated cardboard from shipping boxes is the ultimate base layer for weed suppression, and it’s almost always available for free.
The real magic is in the "fluting"—the wavy inner layer. This structure, combined with the two outer layers, creates a thick, durable barrier that even tough weeds like thistle and bindweed struggle to penetrate. For establishing new beds, lay down a solid layer of cardboard first, overlapping the edges by at least six inches. You can then put newspaper or other mulch on top.
Before using any cardboard, you must do one thing: remove all plastic tape, shipping labels, and any glossy stickers. These materials will not break down and will contaminate your soil with plastic fragments. Once it’s clean, lay it flat, wet it thoroughly, and let it get to work smothering everything beneath it.
What to Avoid: Glossy Flyers and Colored Inks
Not all paper is created equal, and some of it has no place in your garden. The number one rule is to avoid anything with a glossy, shiny, or waxy feel. This includes magazines, catalogs, and the slick, colorful flyers that come in the mail. The coatings used to create that shine often contain plastics, clays, and other chemicals that dramatically slow decomposition and add no value to your soil.
You should also be cautious with heavily saturated colored pages, even if they aren’t glossy. While most modern color inks are much safer than they used to be, cheap, brightly colored inks can sometimes contain heavy metals or other undesirable compounds. When in doubt, stick to the black-and-white pages. A little bit of color on standard newsprint is generally fine, but a fully saturated, bright red ad page is best left for the recycling bin.
The goal of sheet mulching is twofold: suppress weeds and build healthier soil. Anything that interferes with decomposition or potentially adds contaminants is working against that goal. If a piece of paper feels more like a photograph than a newspaper, it doesn’t belong between your vegetable rows.
By rethinking what you consider "waste," you can build a highly effective, budget-free weed control system for your garden rows. Start collecting your local broadsheets and de-taped cardboard today. Your back, your wallet, and your soil will thank you for it all season long.
