About a week after planting, make an application of water soluble fertilizer to the new plants, unless you worked granular fertilizer into the soil when planting. This liquid feed will give the plants a nice boost and spur new root growth.
The new plants wont need water every day unless its very hot and windy, but keep a close eye on them. When you water, give them a nice, slow soak then dont water again until the soil has dried somewhat. A little water every day isnt good and neither is a daily soaking. The best advice I can give is, water the plants when they need it. You can only tell this by looking at the soil and the plants, not by following a calendar schedule someone else may have set up.
