Because a cactus can't grow in clayey soil and there is a lot of water in the marshes, the cactus does not need a lot of water
If you want flowers to grow on your cactus you are supposed to water your cactus.
Cactus don't grow where it is dry, but grow in areas where the periods between rains are long and cactus will store water in their stem to survive these periods. To get a get cactus flowering just keep it dry for 3 months and then give them a lot of water. This will give nature back to the cactus.
Cactus grow very slow because it is saving water for the later time. Cactus grow in the desert, and it merely rains in deserts. So, when it does rain, the cactus takes up as much as water as it can and saves it for the rest of the period of time until it rains again, which is why they grow slowly. They use small amounts of water for itself everyday, which makes it grow slower.

As a cactus is a form of a plant, it will require sunlight for photosynthesis and water to stop it from drying out and to help the cactus plant grow.
A cactus is deeply rooted and, even in a hot desert, there may be dampness below. Also, whenever it does rain, the cactus will store water in special cells that cause the cactus to swell. Another adaptation is that a cactus's covering is waxy to prevent water loss. While it may be hot during the day, temperatures can plummet at night.
Cactus will react to not enough water by turning brown and basically will look very unhappy.

Well, a camel can survive days without water. A cactus hold water and camels eat that and consume the water and can survive days with the water held in its stomach. Hope that helped you :D
