Using cardboard for weed control is an eco-friendly, cost-effective alternative to landscape fabric. While both options suppress weeds, cardboard also enriches the soil as it decomposes, making it a sustainable choice for gardeners. This article explores the benefits and drawbacks of using cardboard versus landscape fabric for weed control, helping you make an informed decision for your garden.
What is Cardboard Weed Control?
Cardboard weed control involves placing layers of cardboard over soil to block sunlight and suppress weed growth. As it breaks down, cardboard adds organic matter to the soil, which improves soil health.
Benefits of Using Cardboard
- Eco-Friendly: Cardboard is biodegradable and made from renewable resources.
- Cost-Effective: Often free or inexpensive, making it accessible for budget-conscious gardeners.
- Soil Enrichment: Decomposing cardboard adds organic matter, enhancing soil fertility.
- Easy to Install: Simple to lay down and cut to fit various garden shapes.
Drawbacks of Using Cardboard
- Durability: Breaks down over time, requiring replacement every few months.
- Moisture Retention: Can retain excess moisture, leading to potential root rot if not monitored.
- Aesthetic: May not be as visually appealing as other options without additional covering.
What is Landscape Fabric?
Landscape fabric is a synthetic, permeable material designed to block weeds while allowing water and nutrients to reach plant roots. It is commonly used in both residential and commercial landscaping.
Benefits of Using Landscape Fabric
- Durability: Can last several years, reducing the need for frequent replacement.
- Moisture Control: Allows water and air to penetrate, preventing waterlogging.
- Neat Appearance: Provides a clean, uniform look in garden beds.
Drawbacks of Using Landscape Fabric
- Cost: Generally more expensive than cardboard.
- Soil Health: Does not contribute to soil fertility.
- Installation: Requires precise cutting and securing to prevent weeds from growing through gaps.

| Feature | Cardboard | Landscape Fabric |
|---|---|---|
| Cost | Low (often free) | Moderate to high |
| Durability | Short-term (months) | Long-term (years) |
| Soil Enrichment | Yes | No |
| Installation | Easy | Moderate |
| Aesthetic Appeal | Low (without covering) | High |
| Environmental Impact | Eco-friendly | Less eco-friendly |
How to Use Cardboard for Weed Control
- Collect Cardboard: Gather large pieces of cardboard, avoiding those with excessive ink or tape.
- Prepare the Area: Clear the area of existing weeds and debris.
- Lay the Cardboard: Overlap pieces to ensure no gaps, and water thoroughly to help it settle.
- Cover with Mulch: Add a layer of mulch to improve appearance and weight down the cardboard.
How to Use Landscape Fabric for Weed Control
- Prepare the Area: Remove existing weeds and level the soil.
- Cut and Lay Fabric: Cut fabric to fit the area, leaving extra for securing edges.
- Secure the Fabric: Use landscape staples to hold the fabric in place.
- Cover with Mulch: Add mulch to protect the fabric and enhance aesthetics.
