Overwatering is too frequently, yes. I like to water when my finger comes out dry. 2-3x a week at most. Pot size and medium will affect how often you water also.
Some people do daily waterings of small quantities but that's all just too complicated for me.
I also use a perlite bed though, catches runoff water and it's filled by a dehumidifier drain. The soil will wick the water up and the plants stay at the right moisture level. I believe most people like a system like this for going away on vacation and not worrying about watering. I like it because it's low maintenance. As long as the perlite bed has water the plants are good, and I just do weekly feedings now.
