Garden brown bin is collected fortnightly during growing season and is free, or rather included. The council compost it to cover the cost. I only use the brown bin maybe two three times per year when I cut the front hedges, because the wheelie bin is more convenient than taking it out back. Grass when cut, is simply distributed on top of where it is cut to rot down, if I collected it there would be far too much for a wheelie bin. Cuttings at the back, branches and trees, go over the back fence to rot down, are burned, or if worth while are offered to those with log burners.
