Grasses and weeds have different responses to drought conditions. Grasses are adapted to survive and even thrive in drought conditions by developing deeper root systems, reducing their leaf area, and slowing their growth. Weeds, on the other hand, may be less tolerant of drought and may struggle to compete with grasses for resources, leading to reduced growth and reproduction. Some weeds, however, may have specific adaptations, such as taproots or water-storing structures, that enable them to survive in drought conditions.
