Cacti/succulents are what I like to call lazy care plants, because I can be lazy with them. (I feel horrible for saying that, but they're great decor with very little effort...) They really don't need much babying because they're used to harsh climate conditions where they go for months without seeing water. Lots of sun and the occasional watering is enough for them. In places like Arizona, New Mexico and parts of Utah, there's a rain season where lots of rain pours for about a week or two and that's usually when the cacti get most of their water for the year.
