What is it I hear you thinking. All the used coffee grounds are saved in foil bags and you can ask for them absolutely free. All you a do is use them as a mulch or add to the compost heap. Quote from the bag says: 'Coffee grounds are a nutritional additive for your soil. During the brewing process most of the acidity is removed, leaving used grounds with an overage ph of 6.9 and a corbon-nitrogen ration of 20-1.'
I haven't got a clue what that means but the roses love them and the compost bin smells wonderful.
