Not very often because cactuses are designed to live a long period without water. I would suggest once every week is fine.
Water is stored in tissue in the stem of the cactus.

it needs water
Too much water or temperatures below freezing can damage or kill a saguaro cactus.
It probably isn't a good idea to drink the water from the saguaro cactus [Carnegiea gigantea]. A cactus plant tends to store its water in bitter or toxic forms. This discourages predators from raiding precious water supplies. So a wiser choice are the saguaro's fruits, flowers, and seeds as sources of nutrition and water. Particularly the fruits and the seeds are succulent sources of drink and food.
Saguaro is a large, tree-sized cactus species in the monotypic genus Carnegiea.
once a week
The saguaro holds water and food inside of it and usally owels nest in them. So you could just say it helps the animals get nutrients.
I don't think there is one, but here's all I can say: -The fruit on the cactus is called a fig. -In late spring, flowers bloom on the cactus arms. -The trunk of the saguaro is the stem. -Inside the cactus, there are tubes that run water through the plant. -There are spiky needles on the outside. -Sometimes, the cactus is crested, where the top is in a fan-like shape. Biologists fight over why.
Elf owls are found mainly in places where there is plenty of water, or in areas where saguaro cactus are grow.
The saguaro cactus is the largest cactus in the United States. It occurs primarily in Arizona and parts of northern Mexico.
The saguaro does not store large amounts of food. It does store large amounts of water with which it can use to produce food, along with carbon dioxide and sunlight.
