Ok, yes, they are established (2+ years). I just thought that a daily
watering would make them appear more robust during the hot summer months,
especially during a drought. However, I also have flowers under eaves which
I'm going to setup sprinklers for too.

One more thing.....Is it possible to plant flowers such as petunias,
marigolds or impatiens at the beginning os summer in June/July? Is this too
late in the season since Spring has already passed and temperatures are
getting hot? These plants will be sitting under these sprinklers and getting
water daily.

If the shrubs are established (ie, if they have been in the ground for 2-3
years), they probably don't need any supplemental water at all. (Except
perhaps in a prolonged drought - 3 weeks or more without rain). If they
are newly planted, they should get an inch of water a week, every week
that you don't get a rain storm where you are. After one year, they
shouldn't need to be irrigated anymore, unless several weeks go by without
rain. All of this is predicated on the idea that the plants are not
underneath the eaves of the house. If they are underneath the eaves, then
you need to water them regularly.

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?
