How often to water arborvitae after planting?

How often should you water the arborvitae after planting? My suggestion would be to water it every day in the second week, then once every two days in the third and fourth weeks, and then about once every three to four days in the fifth and sixth weeks. After six weeks, you can water it once a week or so.

During the first growing season, water it every other day, soaking it deeply. During the second growing season, water it at least once every three days, or more often in the summer. During the third growing season, water it every four days.
