Why Use Cardboard in Your Garden?
Before exploring where to get cardboard, let’s understand why it’s such a valuable resource:
- Weed Suppression: Cardboard forms a natural barrier that blocks sunlight, preventing weeds from growing without harmful chemicals.
- Soil Moisture Retention: It helps retain moisture by reducing evaporation.
- Composting and Soil Building: Cardboard is rich in carbon, balancing nitrogen in compost piles and decomposing to enrich soil.
- Recycling and Sustainability: Using cardboard repurposes waste, reducing landfill contributions.

Many stores receive shipments in cardboard boxes and often discard or recycle them. Politely ask store managers if they can set aside clean boxes for you. Grocery stores, big-box retailers, and hardware stores are excellent options.

What Type of Cardboard Is Best for Gardening?
Not all cardboard performs equally well in the garden. Here’s how to select the best kind:
- Plain Brown Cardboard: The best choice; it breaks down easily and contains minimal dyes or coatings.

Using cardboard properly maximizes its benefits:
Preparation Steps:

Application Techniques:
- Sheet Mulching: Layer cardboard over grass or weed patches, then cover with compost or mulch.
- Pathways: Lay cardboard paths to suppress weeds and reduce mud.
- Compost Carbon Source: Shred cardboard and mix it with green materials.
Environmental Benefits of Using Cardboard in Gardening
