Is it necessary to cover newspaper with another mulch layer? The short answer is yes—covering newspaper with a mulch layer is essential for effective weed control and soil health. Newspapers alone can suppress weeds, but adding a mulch layer enhances moisture retention, improves soil nutrients, and provides a more aesthetically pleasing garden.
Why Use Newspaper as Mulch?
Newspaper is an eco-friendly and cost-effective option for mulching. It acts as a weed barrier by blocking sunlight, which prevents weed seeds from germinating. Additionally, newspaper is biodegradable, gradually breaking down and enriching the soil with organic matter.
Benefits of Newspaper Mulch
- Weed Suppression: Prevents sunlight from reaching weed seeds.
- Cost-Effective: Utilizes recycled materials, saving money.
- Biodegradable: Breaks down over time, enriching soil.
Should You Cover Newspaper with Another Mulch Layer?
Enhancing Weed Control and Moisture Retention
While newspaper alone can block weeds, covering it with another mulch layer, such as straw or wood chips, offers additional benefits. This secondary layer helps retain soil moisture, reducing the need for frequent watering. Moreover, it provides insulation, keeping soil cooler in summer and warmer in winter.
Improving Soil Health
A top layer of organic mulch contributes to soil health by gradually decomposing and adding nutrients. This process enhances the soil structure, promotes beneficial microbial activity, and encourages earthworm activity, all of which are crucial for healthy plant growth.
Aesthetic Appeal
A mulch layer over newspaper enhances the visual appeal of your garden. It provides a uniform, tidy appearance, and you can choose from various materials like bark, wood chips, or straw to match your garden’s aesthetic.
How to Apply Newspaper and Mulch Layers
- Prepare the Area: Clear existing weeds and debris from the garden bed.
- Lay Down Newspaper: Use 6-10 sheets of newspaper, overlapping them to prevent gaps. Wet the paper to keep it in place.
- Add Mulch Layer: Apply 2-4 inches of mulch over the newspaper. Ensure even coverage to maximize benefits.
Types of Mulch to Use Over Newspaper
- Straw: Lightweight and easy to spread; ideal for vegetable gardens.
- Wood Chips: Long-lasting and visually appealing; suitable for flower beds.
- Bark Mulch: Offers a natural look and excellent moisture retention.
