Actually it depends. Right now we aren't having to water really at all because we keep getting a ton of rain. When it starts getting nicer and we aren't drenched I'm sure it will work up to every night. And we live in Western Washington.
Yeah I think you have to evaluate for where you live and what the temp is like ect. Even if it didn't rain here if we had the same temps we're having we could get away with not watering very often. But when it's warmer we wouldn't be able to do that.
Since my garden's in pots, I water daily unless we have a good soaking rain. This week they've mostly been spit and mist.
When I lived in Eastern, WA -- temperate desert -- I relied on a 2-3" mulch and water once or twice a week once the plants were 4 or 5" tall. Until then I would water more as the mulch wasn't in place yet. Our humidity would be in the teens and summer temps 80 to 110. To reduce watering, I also used drip lines and watered at night so there would be less evaporation loss.
I water daily for the most part. I live in the Northeastern part of the US.
