Fight Weeds, For FREE!

Now that garden season is in full swing and we’ve got everything planted, it’s time to kick back and relax, right???… WRONG! This is when the real work begins—weeding all the rows we’ve planted! If you’re anything like us, you know that managing weeds is one of the biggest challenges for home gardeners.

Even though I have a great little helper, pulling weeds gets old fast. So this year, we decided to try some alternative methods for keeping them under control—and the good news is, they didn’t cost a thing.

Here’s what we tried, what worked, and how you can use these natural ways to handle your weed problem—whether it’s in your vegetable gardens, flower beds, or even along your sidewalk.

Alternative Weed Control Methods That Worked for Us

We tried two simple and effective ways to fight weeds using materials we already had on hand:

Cardboard Between Garden Rows

Our first project was laying cardboard between the rows of our garden beds. We got a stack of cardboard boxes from our local grocery store—completely free! With the help of some high school agriculture students, we broke them down and placed them between the rows. At first, it looked like a mess, but once we watered the cardboard down, it settled in nicely.

The result? The cardboard acted as a fantastic weed barrier, preventing weed growth and keeping the soil surface moist for the garden plants we want to thrive.

Newspapers for Sidewalk and Non-Garden Areas

Our second project tackled an area I was tired of dealing with—the sidewalk by our front porch. It doesn’t produce food, but it constantly had unwanted weeds popping up.

So I called my mother-in-law, who showed up with a huge bucket of old newspapers. I added thick layers of newspaper over the area and covered them with pebbles. It’s been over a month, and that walkway has stayed weed-free!

Why Newspaper and Cardboard Beat Landscape Fabric

We’ve used landscape fabric in the past, but to be honest, we weren’t impressed. While it’s marketed as one of the best weed control methods, it comes with a price tag and a few frustrations.

Here’s why we prefer cardboard and newspaper instead:

• It’s completely free. You can find these materials at home or ask neighbors, stores, or friends.
• It breaks down naturally. Over time, these materials compost into the soil, improving its structure and feeding the soil microbes that help desirable plants thrive.
• No plastic waste. Unlike landscape fabric, cardboard and newspaper are biodegradable and don’t add microplastics to your vegetable gardens or flower beds.
• Easy to remove or replace. If you want to change your layout or adjust your beds, cardboard is much easier to move than landscape fabric that’s pinned down and embedded with common weeds.

Why It’s Better Than Hand Pulling or Using Chemicals

If you’ve ever tried to keep up with annual weeds by hand, you know it feels never-ending. And let’s be honest—hand pulling might work on small weeds, but it takes forever and doesn’t always tackle dormant weed seeds or stubborn weeds.

Then there are chemical weed killers, which can harm desirable plants, pollute the soil, and aren’t safe around kids, pets, or food crops. Many home gardeners are searching for a natural weed killer alternative that actually works.

That’s why these methods—cardboard and newspaper mulching—are our go-to solution:

• They stop the growth of weeds at the root.
• They prevent fewer weed seeds from germinating by blocking sunlight.
• They retain soil moisture and reduce the need to water, which benefits plant growth.
• They are safe, chemical-free, and family-friendly.
• They provide good control over unwanted plants without backbreaking work.

When it comes to the best defense against weeds, natural ways like these give you the best results over the long haul.

Where to Use These Free Weed Control Methods

These techniques work great in a variety of areas, especially:

• Garden Beds: Between rows of vegetables, especially those with new plants or smaller seedlings that need space to grow without competition.
• Sidewalks & Pathways: Lay newspaper under rocks, mulch, or pebbles to stop invasive weeds from sneaking in.
• Larger Areas: If you’re converting a larger area of grass or brush into a garden, layering cardboard over the top is one of the best ways to suppress unwanted weeds while building healthy soil.

More Free Garden Ideas to Try This Season

Looking to garden on a budget? I’m all about best practices that help you get the most from your space without spending a dime. Here are two more best management practices that can help you save money and time:

Transplanting Perennials

If you have friends or neighbors with established gardens, ask if you can take some of their perennial divisions. Many plants like hostas, daylilies, echinacea, and mint grow fast and can be divided in spring or fall. It’s a great way to fill in your flower beds or vegetable gardens with desirable plants at no cost. Read more about Transplanting Perennials to Expand Your Garden for Free.

With just a few simple materials you have lying around, you can build a DIY drying rack for herbs like oregano, basil, thyme, and sage. It’s a great way to preserve your harvest naturally and stock your pantry with homegrown flavors all year long. Read more about a FREE Herb Drying Rack In 15 Minutes!

The Proof Is in the Planting

Whether you’re battling common weeds, stubborn weeds, or just trying to find a good control strategy that doesn’t drain your wallet, these natural ways of managing garden weeds really do work. The secret is staying ahead, keeping the soil surface covered, and using smart, sustainable techniques that support both plant growth and your peace of mind.

We’ve seen real results using cardboard and newspaper as a natural weed killer—and so far, it’s been the most effective way to keep our rows clear during the growing season.

The best part? No chemicals, no cost, and way less time spent pulling unwanted plants.
