Newspapers can effectively control a variety of common garden weeds by acting as a physical barrier that suppresses weed growth. This method is eco-friendly, cost-effective, and easy to implement, making it a popular choice for gardeners seeking sustainable weed control solutions.
How Does Newspaper Control Weeds?
Using newspaper as mulch in your garden can help control weeds by blocking sunlight, which is essential for weed germination and growth. By laying down a few layers of newspaper and covering it with mulch, you create a barrier that inhibits weed emergence while retaining soil moisture.
Types of Weeds Controlled by Newspaper
Which Weeds Are Most Affected by Newspaper Mulch?
Newspaper mulch is particularly effective against shallow-rooted and annual weeds. Here are some common types of weeds that can be controlled using newspaper:
- Dandelions: These broadleaf weeds are easily suppressed by newspaper as it blocks the light needed for their seeds to germinate.
- Crabgrass: This annual grass weed thrives in sunny conditions, and newspaper mulch can effectively prevent its growth by cutting off sunlight.
- Chickweed: With its shallow root system, chickweed is easily smothered by a layer of newspaper, halting its spread.
- Lamb’s Quarters: Another common annual weed, lamb’s quarters, can be controlled by the light-blocking properties of newspaper.
- Purslane: This weed’s succulent nature makes it vulnerable to the moisture-retentive but light-blocking effects of newspaper mulch.
Can Newspaper Control Perennial Weeds?
While newspaper mulch is effective against many annual weeds, it is less effective against deep-rooted perennial weeds such as bindweed or quackgrass. These types of weeds may require additional control methods, such as manual removal or targeted herbicide application, to be fully eradicated.
How to Use Newspaper for Weed Control
What Steps Should You Follow?
Implementing newspaper mulch in your garden is straightforward. Follow these steps to effectively control weeds:
- Prepare the Area: Remove existing weeds and debris from the garden bed.
- Wet the Newspaper: Moisten the newspaper to prevent it from blowing away and to help it conform to the soil surface.
- Layer the Newspaper: Lay down 4-6 sheets of newspaper, overlapping them to ensure no gaps where light can penetrate.
- Add Mulch: Cover the newspaper with a 2-3 inch layer of organic mulch, such as straw, wood chips, or leaves, to enhance its effectiveness and improve aesthetics.
- Water Thoroughly: Water the area to help the newspaper and mulch settle and to encourage decomposition.
How Long Does Newspaper Mulch Last?
Newspaper mulch typically lasts for one growing season. Over time, the newspaper will decompose, enriching the soil with organic matter. Reapply the newspaper and mulch annually for continued weed control.
Benefits of Using Newspaper for Weed Control
Why Choose Newspaper Mulch?
Using newspaper mulch offers several advantages:
- Eco-Friendly: Newspaper is biodegradable and can be recycled from your own home, reducing waste.
- Cost-Effective: Newspaper is often free or inexpensive, making it a budget-friendly option for gardeners.
- Soil Health: As it decomposes, newspaper adds organic matter to the soil, improving its structure and fertility.
- Moisture Retention: Newspaper mulch helps retain soil moisture, reducing the need for frequent watering.

Is Newspaper Safe for Vegetable Gardens?
Yes, newspaper is safe for vegetable gardens as most modern inks are soy-based and non-toxic. However, avoid using glossy or colored pages, as they may contain harmful chemicals.
How Thick Should the Newspaper Layer Be?
A layer of 4-6 sheets is typically sufficient to block light and suppress weeds. Ensure the sheets overlap to cover the soil completely.
Can Newspaper Attract Pests?
While newspaper itself does not attract pests, it can create a moist environment that may appeal to slugs. To mitigate this, monitor your garden and use slug deterrents if necessary.
Does Newspaper Mulch Affect Soil pH?
Newspaper mulch does not significantly alter soil pH. It decomposes slowly, adding organic matter without major changes to the soil’s acidity or alkalinity.
Can I Use Newspaper Mulch in All Climates?
Yes, newspaper mulch can be used in various climates. It is particularly beneficial in hot, dry areas where it helps retain soil moisture and in cooler climates where it can insulate the soil.
