Cardboard’s versatility extends beyond weed control and soil improvement. Here are additional ways you can utilize it in your garden.
Planting in Cardboard
For new plantings, consider using cardboard as a temporary planting medium. By cutting holes in the cardboard, you can create planting spots that allow seedlings to grow while simultaneously suppressing weeds.
Pathways and Walkways
Creating comfortable, accessible paths is vital for any garden. Lay down cardboard along your garden paths to suppress weeds while reducing soil compaction from foot traffic. Once covered with mulch or gravel, these pathways provide an attractive and functional solution.
Practical Considerations for Using Cardboard
While incorporating cardboard into your garden offers numerous advantages, there are several practical considerations to keep in mind.
Choosing the Right Type of Cardboard
Not all cardboard is suitable for garden use. Thinner, non-coated cardboard is preferable. Boxes with plastic coatings, glossy inks, or excessive adhesives should be avoided to prevent harmful chemicals from leaching into your soil.
Storage and Preparation
- Storage: Keep your cardboard dry and free from pests before use.
- Preparation: Ensure all cardboard is clean, and remove any tape or labels before laying it on your garden beds.
Conclusion: Transforming Your Garden with Cardboard
