alternative to cardboard to surprise weeds please

Using cardboard to stop weeds does it work as this summer I tried and card caught fire ! What’s the alternative please I have new laid beds with row of Daphne’s which have done very well as roots stayed cool

    Old carpet or thick black plastic should work if you don't want to buy weed-suppressing membrane.

    Just dampen the cardboard.   Old carpet is a nightmare to remove, especially if it's foam backed.  Black plastic will warm up the soil and slow down weeds but doesn't let in moisture.

    Weed suppressing  membrane  but make sure it's permeable.  I planted my black kale and purple  sprouting  broccoli into holes cut in this membrane  and they've  really thrived this summer.  I will be extending this idea on my allotment  next year.

    Many / most carpets nowadays have foam backing and the carpet itself often has a proportion of polypropylene/nylon or other similar fibres which contaminate the soil when the carpet begins to break down. For this reason many allotments have banned the use of carpets to suppress weeds etc.

    Good point about the foam-backed carpet.  We only have the hessian-backed sort so I didn't think of it.

    I would have thought fire a good weed suppressant.
  • Thank you all for advice and carpet is not an option due to reasons given I like cardboard which I keep cool as suggested but long term there is problem of termites if I do nothing and leave soil exposed will this make weeding nightmare or is wood chip going to give same termites problem? I invested in a rotating hoe which seems easy to use any advice gratefully rece.d kalps x

  • Oh!  Suppress weeds!  Right. 

    I'm a bit disappointed now....  :D
