Straw is a dry, hollow stem of cereal plants, such as wheat, barley, or oats, that is often left over after the grain has been harvested. It is commonly used as animal bedding, mulch in gardens, and as a material for thatching roofs. Straw is lightweight and has good insulating properties, making it useful in various agricultural and construction applications. In addition to its practical uses, straw can also be found in crafts and decorations. It is often used to create straw hats, baskets, and scarecrows. Straw is biodegradable, making it an environmentally friendly option for many uses.
