The greater variety of matter you put into the heap the greater varieties of minerals and nutrients your final compost will have. Nettles are good to add from time to time as they help accelerate the breaking down process. The finer you cut the matter the quicker it will break down as well (those tiny microbes can’t take big bites!!)
At the end of the summer/beginning of autumn you ‘put the heap’ to bed for the winter. Pop a piece of old carpet on top and then a bin bag tightly tucked in and this will help to keep the heap warm throughout the winter so the contents can continue their change into beautiful, rich compost.
I am already dreaming about the bounty of fresh fruit and vegetables we will have. I will keep you updated on the progress.
