How Does A Cactus Need So Little Water?
Cacti typically grow in areas with relatively dry climates. In fact, many cacti thrive in areas that are extremely dry, such as the Atacama Desert, which is one of the driest places on Earth. These cacti need water to survive, so how do they?
Due to water scarcity, cacti have developed special abilities that allow them to conserve the water they do receive. They have an extensive shallow root system that allows them to soak up any rainfall that comes their way. The plant stems then store enormous volumes of water for long durations of time. A fully-grown saguaro cactus can soak up and store up to 200 gallons of water during one heavy rain downpour.
Due to this, cactus vegan leather is made with cactus that does not need to be irrigated. The water that is typically used in most of agriculture is avoided entirely, giving cactus an extra point in sustainable fashion.
