I live in the NE USA and my front landscape consists of arborvitae's,
junipers, holley's, a bloodgood, a cherry blossom, various small plants,
etc. These all sit on the NE side of my home that gets mostly half sun/half
shade. The cherry blossom and bloodgood gets more sun, in the range of about
3/4 sun and 1/4 shade.

Recently, I setup a neat little Nelson sprinkler system surrounding these
shrubs and set a timer to sprinkle them twice a day at 7am and 7pm, for 15
minutes each session.

Should I be watering these shrubs this often, this long, or at all?
