This means that there is less water available for plants to absorb through their roots. Cactus plants have a long-dormant period followed by a short growing season. The desert is one of the harshest environments on Earth, yet cacti have adapted to survive in this hostile environment. How do they do it? Since its hot in the desert during the day, the cactus plants stomata only open up at night when temperatures are cooler, hence fewer chances of water loss. One such adaptation is the flowers of cactus plants. The roots of the cactus penetrate deep The best time to do so is in early spring after the frost threat has passed and the moss has time to acclimate before the temperature rises. A shallow root system allows cacti to absorb as much water as possible when it rains, as well as providing access to small amounts of moisture that may occur at the surface due to fog, mist, or morning dew. The structure allows channeling of water to various parts of the plant. A waxy layer covers most of the plants surface (except for the stomata).
