Hello! I have a compost question. This is my first attempt at composting - I just completed a bin (3'width x 5'length x 3'height). I have plenty of brown material, but what can I add this time of year that would be considered green? We do eat a lot of vegetables - but the ratio seems too small! Is there something other than actual 'green material' that I can substitute in the winter? Any suggestions would be greatly appreciated.
