Arborvitae root issues, should we dig it?

Q: We planted 17 emerald arborvitaes 3 weeks ago. We broke apart the rootball (at the suggestion of an employee at the retailer) and I've since learned that this is bad to do. We are watering regularly and have covered the area with mulch to retain moisture but our trees seem to be yellowing slightly. What can we do to encourage survival? I'm worried we may have shocked them too much. Any type of fertilizer we can use to encourage root growth/provide nutrients?
