Compost

Compost is a nutrient-rich, dark-colored material produced from the decomposition of organic waste, like yard clippings, food scraps, and animal manure. It acts as a natural fertilizer and soil conditioner, improving soil structure, fertility, and water-holding capacity

Soil

Soil is the unconsolidated mineral and organic material at the Earth's surface, providing a medium for plant growth and supporting various organisms. It's a complex mixture of inorganic particles (like sand, silt, and clay), organic matter (decayed plants and animals), air, water, and living organisms. 

Bark Chippings

Bark chippings are simply pieces of tree bark, typically from spruce or pine, that have been chopped or shredded into small pieces. They are often a by-product of the timber industry and are widely used in gardening and landscaping as a mulch.
