Sounds good but do not water it that much (daily). Use the finger method to determine when to water. During the next 2-3 weeks, do this:
"To determine if the soil needs water, during the early morning hours, use a moisture sensor or insert a finger into the soil to a depth of 4" and water if the soil feels dry or almost dry."
Each time that you water the plant, make a note in a wall calendar. After 2-3 weeks, review the calendar's notes and determine how frequently you had to water (every 2/3/4/5/etc days for example). Then set the sprinkler to water 1.5 gallons on that same frequency (every 2/3/4/5/etc days).
Use the finger method for 2-3 weeks if temps change 10-15 degrees and stay there. Eventually, reduce the amt of water per watering to 1 gallon in the Fall. When the plant goes dormant, you can reduce it further to watering once a week or once every two weeks (probably depends if it is dry or wet). Stop watering if the soil freezes and restart when it has warmed up in the Spring. When you restart, make sure the mulch is still 2-4" deep and use 1 gallon of water per watering again.
