I've got a load of cardboard (house move) and this years supply of muck on its way to my new allotment plot. About half of the plot is currently under black plastic and likely to stay that way for the first year as I know my limitations. The muck is pretty fresh. Can I put down the cardboard on grassy/weedy areas and put the muck on top? The theory is that by autumn or next spring, the cardboard and manure will be rotted enough for cultivation and the weeds below will be dead. Any thoughts?

    Sounds ok to me

    Certainly sounds like a plan to me CD - but I've never done it. Hopefully somebody else will be able to give you a definite thumbs up or highlight any potential problems.

    as the muck is fresh, you might well get weeds coming through, just keep pulling them up and start a compost bin.

    Cardboard, muck, more cardboard. Its called the lasagne method.

    Being mean I have only used one layer of cardboard (no muck) and it all blew away over winter so the weeds are free to rampage across the Blessed Plot without so much as a by your leave.

    Be worth giving the cardboard a really good soaking before you lay the muck on top, it will breakdown quicker.

    I put large sheets of cardboard on my allotment and within a couple of weeks with rain they were about rotten. However I would have thought if you are then going to cover with muck while still dry then this will be a good long lasting weed control.

    Not sure how long it will take the cardboard to break down though and for the muck to actually start doing its job with the soil underneath.

    I guess if you are going to leave for several months then should be ok.

    Maybe throw some water on it occasionally if the weather is hot and dry?

    It is a good idea and should help. Especially for no-dig gardening. Look up Charles Dowding here
