Leaves, branches and grass from the garden, eggshells, fruit and vegetable peelings, coffee grounds, tea bags and bread from our tables can all join the compost heap. If mixed well, turned regularly and kept sufficiently moist, in a few weeks this will yield compost, a natural fertilizer that is good for the soil. Whether you make a compost heap or use a bin, there is certainly a composting option suitable for the amount of space you have available.
