干し草 (hoshi kusa) refers to dried grass, commonly used as animal feed, particularly for livestock like 牛 (cattle) and 馬 (horses). It is typically harvested during the growing season, dried in the sun, and then stored for later use. This process helps preserve the nutrients in the grass, making it a valuable resource for farmers. In addition to animal feed, 干し草 can also be used for various purposes, such as bedding for animals or as a natural mulch in gardens. Its lightweight and fibrous nature make it easy to handle and transport, contributing to its popularity in agricultural practices.
