Cardboard is one of my favorite ways to suppress weeds when building a new garden bed, but not all cardboard is created equal.
In this video, I’ll show you what to look for before adding cardboard to your garden, including:
• What types of cardboard are best
• Why tape and labels should be removed
• Which coatings to avoid
• How to prepare cardboard before covering it with soil or mulch
Using the right cardboard can help reduce weeds while improving your soil over time as it naturally breaks down.
Have you used cardboard in your garden beds? Let me know in the comments.

Did you leave those staples in? It looks like those staples probably contain some copper. If there is copper there and you bury it in soil or compost, it will eventually break down into copper sulfate. Enough copper sulfate could kill the roots of your plants and any other plant tissue it touches. It acts in a number of different ways. Fascinating stuff.
