Large heavy duty plastic compost bin with lid and open base. Stand the bin on soil, fill with all your vegetable peelings, weeds from your garden, grass clippings etc and keep the lid on. As you keep adding plant material it gradually rots down making the most useful compost to add to plants in pots, planting holes for garden plants and top dressing to enrich your garden soil. The lid keeps in any odour, and the bin's dark green colour disguises it in your garden. Once full, take off the most recent layer and use the compost underneath. Replace what was the top layer and begin the process again. Compost is essential in the garden and making your own means its FREE.
