What Are the Benefits of Using Cardboard as a Weed Barrier?
Using cardboard as a weed barrier offers several benefits, making it a popular choice among gardeners looking for sustainable options:
- Eco-Friendly: Cardboard is biodegradable and recyclable, reducing environmental impact.

- Soil Health: Cardboard can improve soil quality as it decomposes, adding organic matter.
What Are the Potential Problems with Cardboard as a Weed Barrier?
While cardboard is a viable option, there are several potential issues to consider:
- Decomposition Rate: Cardboard may decompose too quickly, especially in wet climates, requiring frequent replacement.
- Pest Attraction: Cardboard can attract pests like termites and slugs, which may damage plants.
