Cactus in one of the plants that remind you of a desert. And a desert is marked by dry and barren lands that do not have any trace of water. Now that cactus has been the plant that grows in the desert lands; it should go without saying that it goes without water for a long time. But have you ever given a thought to the question – how long can a Cactus go without water? So, how long can a cactus go without water? Cactus has developed a few great survival techniques and can go a long time without water. Some of the cacti species can go without water for as long as two years. The cacti have thick stems that can store water and consume it whenever needed. They also have a protective layer that prevents the loss of water. However, indoor cactus will need frequent watering to keep it alive. How Long Can A Cactus Live Without Water? On an average, the cactus plants can survive without water for a period of around two years. However, that should not mean they will continue to live without water forever, or even for long. Being a living thing, cactus does need water and will die if they do not get enough water. Photo: visitcalifornia.com They can survive without water for a more extended period of time simply because they have developed a few unique features as an evolutionary strategy, and thus store enough water and consume it only when needed. When compared to the plants in the other regions, the cactus and similar other desert plants store water in their roots and stems. They have modified the leaves into a variety of ways so that the water is not lost through the process of evaporation. If you believe that cacti have deeper roots to store water, you are wrong once again. They do not have deeper roots to extract more water from underground but have shallow roots that go only a few inches inside the ground. How long a cactus can go without water depends upon several factors and is not the same across all the cacti out there. How long can a cactus go without water will depend on the species of the cactus, its size ad the location that is found to be growing. What helps cactus in surviving without water for many days? What makes cactus survive without water for long? How does cactus plant live without water? Cactus plant makes this possible by developing a few adaptations and modifications in its anatomy to help them preserve whatever water they receive during the scarce rains. The prickly spines and the extensive roots are what make it one of the best features that a cactus develops that helps it survive without water for many days. The prickly spines you find on the cactus are, in fact, the modified leaves. The spines serve two significant purposes – they prevent the plant from being eaten by the desert animals, and they also prevent the loss of water through evaporation which can be a huge issue given the dry air prevalent in a desert. The cacti also have an extensive but show roots which help in preserving the water. The roots extend to a longer distance around the plant, thereby making sure that they can soak up as much water as possible and store it. Since the rain can be extremely scarce in the desert and similar arid areas where cacti grow, these develop a thick stem that lets them store much water that can stay without evaporation for a more extended time period. A good example can be the Saguaro species that can absorb and store up to 200 gallons of water. How Much Water Does a Cactus Need? There are no ways to find an exact amount of water that a cactus would need to survive. We can only make a generalisation with respect to finding how much water does a cactus need to survive.

Method 2: This method can involve submerging the cacti plant into the water. This method should ideally work with the cactus plants that have bigger and thick roots. You can even decide to apply water on the surface of the water. The amount of water in this method would ideally be dependent on the sunlight and heat that it does receive.
