How often should I water new plants?

I like to water by hand directly after planting, and to make sure that things are watered in very well. On newly established plants, we need to come in almost every other day and check on the watering, because you've got to remember that we have a fairly small root system. Particularly, if we're doing a lot of herbaceous perennials. They haven't rooted out into the ground yet, so we need to keep them moist until they start to establish. Usually for the first couple of months, at least, we're checking every couple of days to every three days to make sure that the plant is establishing and not wilting.
