Is newspaper or cardboard effective for weed suppression? Both newspaper and cardboard are effective for weed suppression when used correctly. They work by blocking sunlight, which prevents weeds from growing. These materials are also biodegradable, making them environmentally friendly options for gardeners looking to control weeds naturally.
How Does Newspaper Work for Weed Suppression?
Newspaper is a popular choice for weed suppression due to its accessibility and cost-effectiveness. When you lay down several layers, it effectively blocks sunlight, which is essential for weed growth. As the newspaper decomposes, it enriches the soil with organic matter.
Steps to Use Newspaper for Weed Control
- Prepare the Area: Clear the area of existing weeds and debris.
- Wet the Newspaper: Dampen the newspaper to keep it in place and speed up decomposition.
- Layer the Newspaper: Use 5-10 sheets of newspaper to ensure adequate coverage.
- Cover with Mulch: Add a layer of mulch on top to improve aesthetics and further suppress weeds.
Advantages of Using Newspaper
- Cost-Effective: Newspapers are often free or inexpensive.
- Biodegradable: They break down naturally, improving soil quality.
- Easy to Use: Simple to lay down and maintain.
Is Cardboard Better for Weed Suppression?
Cardboard is another excellent option for suppressing weeds. It is thicker than newspaper, providing more robust coverage and longer-lasting weed control. Like newspaper, cardboard decomposes over time and adds organic matter to the soil.
How to Apply Cardboard for Weed Control
- Clear the Area: Remove existing weeds and level the ground.
- Cut and Lay Cardboard: Cut the cardboard to fit the area and overlap the edges to prevent gaps.
- Wet the Cardboard: Moisten the cardboard to help it stay in place.
- Cover with Mulch: Apply a layer of mulch to enhance appearance and effectiveness.
Benefits of Using Cardboard
- Durability: Thicker than newspaper, offering longer-lasting suppression.
- Recyclable: Utilizes materials that might otherwise be discarded.
- Improves Soil Health: Decomposes and enriches the soil.
