How often should I water a cactus?

Question

I just bought a cactus that is a little bit bigger than a ping pong ball and was wondering how often and how much I should water it. Thanks in advance!

Answer 1

Cacti can go months without water.  Let the soil dry out.  Think of the desert climate, where the grow in nature.  The desert is hot in the day, cool at night.  It is dry and not humid.  Many die-hard cactus owners check the weather reports in areas like Arizona and Nevada.  When it rains, they water.  In short, I water once a month at most.  You can buy cacti fertilizer drops (Walmart, grocery store) to add to the water to feed the prickly pal.  Have fun!
