Why Put Cardboard At The Bottom Of A Garden Bed?

When it comes to setting up your garden bed, one popular practice is to line the bottom of it with cardboard. But why exactly would anyone do that? Let’s delve into the benefits of such a practice.

1. Weed Suppression

By placing a layer of cardboard at the bottom of your garden bed, you create a barrier that helps suppress weed growth. The cardboard blocks out sunlight, which inhibits the germination and growth of weed seeds, thus reducing the need for constant weeding.

2. Soil Protection

Cardboard acts as a protective barrier between the soil in your garden bed and any potential contaminants in the ground below. It helps prevent soil compaction, improves soil drainage, and protects the soil ecosystem from external factors.

3. Moisture Retention

One of the advantages of using cardboard in your garden bed is its ability to retain moisture. By keeping the soil beneath it moist, the cardboard helps create a favorable environment for plant roots to absorb water and nutrients more efficiently.

4. Decomposition and Nutrient Recycling

Over time, the cardboard breaks down naturally, contributing to the decomposition process in your garden bed. As it decomposes, the cardboard adds organic matter to the soil, enriching it with nutrients that benefit plant growth.

5. Pest Control

Cardboard can act as a physical barrier that deters certain pests and insects from reaching your plant roots. It creates a less hospitable environment for pests, helping protect your plants from potential damage.

6. Cost-Effective Solution

Compared to other landscaping materials like landscape fabric, cardboard is a more cost-effective option for lining the bottom of your garden bed. It serves multiple purposes at a fraction of the cost, making it a budget-friendly solution for gardeners.

7. Eco-Friendly Choice

Using cardboard in your garden bed aligns with eco-friendly practices by repurposing recyclable materials. Instead of discarding cardboard, you can give it a new life in your garden, reducing waste and promoting sustainability.

8. Enhanced Plant Growth

By creating a favourable environment for plant roots to thrive, cardboard contributes to enhanced plant growth in your garden bed. Healthy soil conditions facilitated by the cardboard layer can lead to stronger, more robust plants.

9. Easy Installation

Putting cardboard at the bottom of your garden bed is a straightforward process that requires minimal effort. Simply lay down the cardboard, ensuring full coverage, and start building your garden on top of it for hassle-free installation.

10. Aesthetic Appeal

In addition to its practical benefits, cardboard can also add a touch of rustic charm to your garden bed. Its natural appearance blends well with the surrounding environment, enhancing the overall aesthetic appeal of your gardening space.

11. Versatile Application

Cardboard is a versatile material that can be used in various gardening scenarios beyond just lining garden beds. From sheet mulching to composting, cardboard proves to be a valuable resource that offers multiple uses in the garden.

12. Improved Gardening Experience

Ultimately, incorporating cardboard at the bottom of your garden bed can lead to an overall improved gardening experience. From easier maintenance to healthier plants, the benefits of using cardboard in your garden bed are numerous and well worth considering.
