    Default Composting grass clippings on their own. Is it possible

    I have lots of grass clippings, 300 square yards of grass, but nothing else to add to it for most of the year. The only other garden waste I have is shrub pruings from euonymus, laurel. I produce very little kitchen waste. I don't have a shredder.

    Rather than putting the grass into my green waste bin is there any way I can compost it. Previous attempts have just produced a wet mush. Thanks.

    I think you can use it as a mulch, I assume someone with more knowledge will reply soon:-)

    You cannot compost just one item, there has to be a mixture, I add quite a lot of grass in my bin, but also veg peelings, tops/stems from the kitchen along with some shredded paper, there is a formula, but I have never followed one.

    Needs some dry, high carbon material mixed in otherwise the grass clippings mat together and go anaerobic. You could use the clippings as a mulch: I use them around rhubarb, apple trees, fruit bushes, raspberries, big plants like brassicas and squash and as a top dressing for tomato/pepper/cucumber pots in the greenhouse.

    It would need turning regularly, every few days or so at first.

    A big help would be ripped up card, cardboard and scrunched up paper to add browns and air pockets.

    I also use mine as a mulch plus it’s handy to top up container grown potatoes along with shredded paper.

    Grass will compost alone but needs *lots* of turning to prevent matting - like daily. With frequent turning the heap will heat quickly and give good compost quite quickly. Even better if you add a *little* high-nitrogen fertilizer such as Nitram, if you can get hold of it, or urea. Don't over do this or it will catch fire!

    Mixing in a few shovels of soil helps. The soil helps to aerate the pile, absorb excess water, and introduces microbes to rot the grass.
