The cardboard mulch

In 2010, I decided to get rid of my lawn. Not wanting to use weedkillers, I used a mixture of carpet over the grass and overturning the turf round the edges. This worked reasonably well, to the extent that I have been growing things in this area for last couple of summers.

The grass has not gone away completely, though, with the result that I find myself continually digging out clumps of it as well as other ‘weeds’. Indeed, there is a particularly bad patch, which in honesty had not been dealt with originally (just manual pulling up by the roots). And now it is once more turning into lawn – but hopefully not for much longer. Having learned that cardboard will suppress whatever is growing under it (okay not the roots of perennials, which I will have to dig out later), I’m going to try it out.

Cardboard as weedkiller

The cardboard should in theory suppress the grass and as it rots down provide a mulch for the soil which then stops other weeds gaining a foothold. I could pile manure/compost on top to condition the soil as well, but I’ll see how the cardboard fares first. At least so far, it hasn’t required a lot of effort on my part. Unless devouring the party food which was in the box counts as work!

About Helen

I have always been interesting in living a more environmentally friendly lifestyle and used to do what I could. Now, I have come to realise that we have reached such a point in terms of environmental degradation that it is more important - perhaps - to focus on building resilience. I therefore do as much as I can to reuse, grow my own and encourage a supportive community, for example. I also keep reading and learning all the time.

    This does work. We’ve used it.

  2. Reblogged this on Linda's wildlife garden and commented:
    Lovely update thank you for sharing Helen have a blessed day

  3. I think you will be pretty impressed with the results…Good luck, nothing is a silver bullet except time and staying with it.

  4. I wanted to hear that this works. I hate digging out all the sod to start a new garden. Really good weed barrier works, but its not free like card board. and then if you want your perennials to spread it becomes a problem. I wish there was an easy solution.

    • Yes, I can see there is a disadvantage in all things! Still, if you have ground cover through your perennial flowers, there should be fewer problems with weeds in the first place.

  5. That’s a great idea.

  6. It really works well. I placed cardboard and grass clippings on an area of lawn and let it rot down. I planted herbs here and the soil is so rich and black, the best soil ever, and no digging, bonus 🙂

    • Great to hear of your success!

      Not sure what I am going to do in the short term with the patch of ground where the cardboard is, once the grass has gone from underneath as it is in an awkward spot, but I look forward to seeing the results.
