Shredded cardboard for mulch

Posted by plantveggies (My Page) on

Is it a good idea to use shredded cardboard to mulch my vegetable raised bed? I shred corrugated cardboard with a paper shredder so the cardboard is in thin strips.

Sure - I love using cardboard, as the worms are so happy underneath it. You can also throw it into your compost bin.

Amen, keep it moist and the benefits never end.

Earthworms, and other members of the Soil Food Web, like the soil conditions created when mulches are used, cool, moist soil, so any material used as a mulch will get them there. Shredded cardboard will work, but I am not sure that the extra labor involved in shredding cardboard is really worth the effort. I see very little difference in my soil if the cardboard is laid down unshredded or if I shred it, except I need more shredded cardboard to get the same results as with unshredded cardboard, and the shredded cardboard allows more "weed" growth then the unshredded cardboard does.

Thank you for your responses. I want to use shredded cardboard because it is easier to spread around my plants. Also, it will decompose faster. For areas without plants, I will put cardboard sheets to suppress weed groeth.

First of all, I do use cardboard under mulch etc., But lately I have been wondering if one needs to worry about the glue or whatever chemical they use to make cardboard? Do they have harmful elements when used in vegetable beds? Since we really don't know where all these cardboard came from.
