Using newspaper or cardboard to suppress weeds on garden paths is an effective and eco-friendly method. This technique, known as sheet mulching, helps reduce weed growth by blocking sunlight and creating a barrier that prevents weed seeds from germinating. Additionally, as the paper decomposes, it enriches the soil, promoting healthier plant growth.
Why Use Newspaper or Cardboard for Weed Suppression?
Suppressing weeds with newspaper or cardboard is a sustainable alternative to chemical herbicides. This method is cost-effective, utilizes materials that are often readily available, and is easy to implement. It’s particularly beneficial for those looking to maintain an organic garden.
Benefits of Using Newspaper and Cardboard
- Eco-friendly: Both materials are biodegradable and help reduce waste.
- Cost-effective: Often free or inexpensive, especially if you recycle old newspapers or boxes.
- Soil Improvement: As they decompose, they add organic matter to the soil.
- Ease of Use: Simple to lay down and maintain.
How to Use Newspaper or Cardboard for Weed Suppression
Step-by-Step Guide
-
Prepare the Area: Clear the garden path of existing weeds and debris. This ensures the paper lies flat and has maximum contact with the soil.
-
Gather Materials: Collect newspapers or cardboard. Remove any glossy or colored sections from newspapers and tape or labels from cardboard, as these may contain non-biodegradable materials.
-
Soak the Paper: Wet the newspaper or cardboard thoroughly. This helps them stay in place and begin the decomposition process.
-
Lay the Paper: Place the wet newspaper or cardboard on the path, overlapping edges by at least 6 inches to prevent weeds from sneaking through gaps.
-
Add Mulch: Cover the paper with a layer of organic mulch, such as wood chips or straw, to weigh it down and improve its appearance.
-
Maintain the Path: Regularly check the path to ensure the paper is intact and replace any sections as needed.
Practical Example
Imagine a garden path lined with persistent weeds. By laying down a few layers of newspaper, you effectively create a barrier that blocks sunlight, preventing weeds from growing. Over time, the newspaper decomposes, leaving behind a healthier, weed-free path.
Cardboard vs. Newspaper: Which is Better?
| Feature | Newspaper | Cardboard |
|---|---|---|
| Availability | Often more readily available | Requires collection of boxes |
| Durability | Decomposes faster | More durable, longer-lasting |
| Ease of Use | Easier to lay in small spaces | Better for larger areas |
| Cost | Typically free | Free from deliveries or stores |
Both newspaper and cardboard are effective, but the choice depends on the specific needs of your garden path. Cardboard is more durable, making it suitable for larger areas, while newspaper is easier to handle and better for smaller spaces.
People Also Ask
How long does it take for newspaper or cardboard to decompose?
Newspaper generally decomposes within 6-8 weeks, while cardboard can take several months. The decomposition rate depends on factors like moisture levels, temperature, and the thickness of the material.
Can I use colored newspaper for weed suppression?
It’s best to avoid using colored or glossy newspaper sections, as these may contain inks or coatings that are not biodegradable and could harm the soil.
Does using newspaper or cardboard attract pests?
While decomposing materials can attract insects, covering the newspaper or cardboard with a thick layer of mulch can minimize pest attraction and improve the visual appeal of your garden path.
What type of mulch should I use over newspaper or cardboard?
Organic mulches like wood chips, straw, or shredded leaves are ideal. They add nutrients to the soil as they break down and help retain moisture.
Can this method be used in vegetable gardens?
Yes, using newspaper or cardboard in vegetable gardens is safe and beneficial. Ensure that any materials used are free from harmful chemicals or inks.
