Preparing the ground before laying newspaper or cardboard is an essential step for effective weed control and soil improvement in gardening. This process, often referred to as sheet mulching or lasagna gardening, involves layering organic materials to suppress weeds and enrich the soil. Here’s how you can prepare your garden for this method.
Why Prepare the Ground Before Laying Newspaper or Cardboard?
Before you lay down newspaper or cardboard, it’s crucial to prepare the ground to ensure maximum effectiveness. Proper preparation helps in:
- Suppressing weeds: A well-prepared base prevents weeds from growing through the layers.
- Improving soil health: Organic materials decompose over time, enriching the soil with nutrients.
- Retaining moisture: The layers help in moisture retention, reducing the need for frequent watering.
Steps to Prepare the Ground
1. Clear the Area
- Remove existing vegetation: Use a garden hoe or spade to cut down weeds and grass at the base.
- Dispose of debris: Clear away rocks, sticks, and other debris that could puncture the newspaper or cardboard.
2. Water the Soil
- Moisture is key: Thoroughly water the soil to ensure it’s damp. This helps in breaking down the organic layers faster.
- Check for drainage: Ensure the area has proper drainage to prevent waterlogging.
3. Level the Ground
- Smooth the surface: Use a rake to even out the soil. A flat surface ensures uniform coverage of newspaper or cardboard.
- Fill in low spots: Add soil to any depressions to create a level base.
How to Lay Newspaper or Cardboard
1. Choose the Right Material
- Newspaper: Use 6-8 layers of newspaper. Avoid glossy pages as they contain chemicals.
- Cardboard: Use plain, untreated cardboard. Remove any staples or tape.
2. Lay the Material
- Overlap edges: Ensure a 6-inch overlap between sheets to prevent weeds from sneaking through.
- Cover the entire area: Make sure there are no gaps.
3. Water Again
- Soak thoroughly: Water the newspaper or cardboard to help it adhere to the soil and start the decomposition process.
4. Add Organic Material
- Layer with mulch: Cover with a 2-3 inch layer of organic mulch, such as straw, wood chips, or grass clippings.
- Compost addition: Add a layer of compost to enhance nutrient content.
Benefits of Using Newspaper or Cardboard
- Natural weed barrier: Blocks sunlight, preventing weed growth.
- Environmentally friendly: Recycles materials that would otherwise be waste.
- Improves soil structure: Decomposes to enhance soil texture and fertility.
Common Mistakes to Avoid
- Using glossy materials: These can introduce toxins into your garden.
- Skipping watering steps: Dry layers take longer to decompose and can blow away.
- Insufficient overlap: Gaps allow weeds to grow through.
People Also Ask
What are the best materials for sheet mulching?
The best materials for sheet mulching include layers of newspaper or cardboard, followed by organic mulch like straw, wood chips, or leaves. These materials decompose over time, enriching the soil.
How long does it take for cardboard to decompose in the garden?
Cardboard typically takes about 6-12 months to decompose, depending on moisture levels and the thickness of the layers. Keeping the area moist accelerates decomposition.
Can I plant immediately after laying newspaper or cardboard?
It’s best to wait a few weeks before planting. This allows the materials to start breaking down and settle properly. However, you can cut holes in the layers to plant immediately if needed.
How thick should the mulch layer be?
A mulch layer should be 2-3 inches thick. This thickness helps retain moisture, suppress weeds, and provide a steady supply of nutrients as it decomposes.
Is sheet mulching suitable for all types of gardens?
Sheet mulching is ideal for most garden types, especially vegetable gardens and perennial beds. However, it’s less effective in areas with poor drainage or heavy clay soils.
Conclusion
Preparing the ground before laying newspaper or cardboard is a straightforward yet effective way to improve your garden’s health and productivity. By following these steps, you can create a sustainable, low-maintenance gardening system that benefits both your plants and the environment.
