Laying Down The Cardboard
Next, cut the cardboard into manageable pieces and lay them flat on the prepared garden area. Ensure that the pieces overlap by at least six inches to prevent any weeds from sneaking through the gaps. If necessary, use a box cutter or scissors to shape the cardboard around your plants and garden edges.
Covering The Cardboard Layer
Once the cardboard is in place, cover it with a layer of organic mulch. The mulch will keep the cardboard weighted down and provide an additional barrier against weeds. Spread the mulch evenly, creating a layer that is two to three inches thick. This will not only suppress weeds but also help retain soil moisture and regulate temperature.
Watering And Maintenance Tips
After spreading the mulch, water the entire area thoroughly to help the cardboard settle and begin breaking down. Throughout the growing season, check the mulch layer periodically and add more as needed to maintain its thickness. As the cardboard decomposes, it will enrich the soil, and you can simply add new cardboard layers at the start of each planting season.
Benefits Of Using Cardboard Over Other Methods
The use of cardboard as a weed suppressant offers numerous :
1. It is cost-effective and often free if you have old boxes lying around.
2. It is environmentally friendly and decomposes naturally, enriching the soil.
3. It avoids the potential harm of chemical herbicides.
4. It allows water and nutrients to reach the soil, unlike plastic barriers.
5. It provides a practical use for recyclable materials that might otherwise go to waste.
Common Mistakes And How To Avoid Them
Some common mistakes to avoid :
1. Using glossy or heavily inked cardboard, which may contain harmful chemicals.
2. Not overlapping the cardboard sufficiently, allowing weeds to find gaps.
3. Failing to use enough mulch to weigh down the cardboard.
4. Neglecting to water or maintain the mulch layer.By being mindful of these points, you can ensure a more effective weed suppression process.
