Water your garden when it needs it.

Sorry, but it's hard to be more specific, it depends on so many things. Did you get any rain? How humid is your air? Are they in full sun? What plants are we talking about (Tomatoes and peppers need a lot more water than herbs)? Are they mulched? How hot is it?
So watering on any kind of schedule doesn't always work, because if it is really hot they will need more water than if cooler, if it rains then you don't need to water, etc.
Put your finger in down to the knuckle. If the soil is dry that far down, then water.
In general for ESTABLISHED plants (not seedlings or stuff you just put in the ground), you want to water deeply but less often. That helps them put down deep roots, which makes them healthier. So I usually water once a week ish, less if there's any rain, maybe more if it is really hot and sunny. I keep my beds mulched, which helps conserve water.
Hope this helps some.
