Grass Cuttings Experiment
In the spring my neighbour gave me a spare Dalek compost bin,
as he had made "proper" compose bins. I decided to use it just for grass cuttings and keep my other Dalek for other compostables. Before everyone throws up their hands in horror at the potential thick solid mess that could ensue, I have layered the grass cuttings with shreded paper, as I used to do in my "proper" bins before I moved. Now we have got to the end of the grass cutting season (I hope!) I am wondering what the next step should be: 1) Just leave it as it is 2) Put some more paper on the top with some weights to compress 3) Stir it up with a fork (if I can reach in to the bottom!) and then take options 1 or 2 above. Any thoghts welcome Ta -- Roger T 700 ft up in Mid-Wales --- This email has been checked for viruses by AVG. https://www.avg.com |

That should stir it enough to mix it and get air into it. Adding more shredded paper or similar is probably a good idea as well. Shredded paper (enough of) makes a huge difference in my hotbin between failure and 70C composting. Chippings work and I have observed dried crinkly leaves have done some good in lieu of paper when I ran out. So does cardboard stuffed through the chipper (mine can). Good way to lose a few Amazon boxes. It's possible the chemical composition of paper is advantageous over the other options with regard to it becoming part of the breakdown process and supplying carbon to the reactions, as opposed to merely keeping the pile ventilated - I'm not 100% sure. I can see that being an issue with chippings, but leaves??? |

I do absolutely nothing to my dalek composts. I keep the lid on and because it's warm and dry the dalek gets colonised by millions of ants which chew up the contents into a fine brown "soil" like potting compost. When they're done, lift off the dalek to position elsewhere. Now you have access to the ants' product. Any left-overs that they haven't processed, I just leave as mulch. Wish my ants would live in the daleks rather than filling my water cock pit in the pavement with soil every year :-| Literally 2m away! |

Disturbing it to let more air in is important as is just the right amount of moisture. This year has been a bit dry. Smaller heaps seem to benefit from Garotta (other brands available). Shredded paper (enough of) makes a huge difference in my hotbin between failure and 70C composting. I'm not entirely convinced that the ratio of brown to green material really matters that much so long as you add enough of it in a single go for it to get properly hot internally. I add about 1m^3 at a time and except right at the start of the season it goes hot within 3 days. Once or twice I have had it smouldering internally with smoke. Smells of short chain fatty acids when it is at if hottest. Chippings work and I have observed dried crinkly leaves have done some good in lieu of paper when I ran out. So does cardboard stuffed through the chipper (mine can). Good way to lose a few Amazon boxes. It's possible the chemical composition of paper is advantageous over the other options with regard to it becoming part of the breakdown process and supplying carbon to the reactions, as opposed to merely keeping the pile ventilated - I'm not 100% sure. I think the main thing is to allow enough air in and not squash it down. If it goes anaerobic then foul smelling green slime is the result. I can see that being an issue with chippings, but leaves??? Leaves tend to have a lot of tannins in which inhibit some of the fungi. I make my own leaf mould - using the green recycling bin. One bug green bin produces enough proto leaf mould to fit in a small classic black bin. It takes two to three years to produce good quality leaf mould. -- Regards, Martin Brown |
