What is the best time to water the grass and plants? I live in Houston, TX and just bought a home. The sprinkler system is already in place which runs through all the 6 stations at 7:00 AM in the morning.

It waters each station for 10 minutes.

...any time between 4:30-5:00am and 8:00am is the recommended time
frame to run the sprinklers.. this is because when the yard recieves
water at this time, ..it is most benificial to the plants.. watering them
later can result in burning of the leaves.. and watering during the evening
can encourage viral and fungal disorders such as mildew..because the
plants/lawn grasses remain wet through the night time hours..

...as for the frequency...the amount needed will depend on the time of
year..and the overall conditions... during the cooler months,..a lawn area
will need alot less waer then during the warmer months..especially during
a drought...

..the best technique ive learned so far is to set the sprinkler controller
into durations of 2 or 3 times per time watered..i know that probabaly
sounds a bit confusing so heres an example...

...if the plants/lawn area recieves 10 minautes of water per cycle,..
divide that into two 5 min cycles each... with a 15-30 minaute rest
between each cycle..the idea is to allow deeper penetration of the
water each time, promote the roots of the lawn grasses/plants to
grow deeper,and to cut down on runoff...

..the way ive done this myself is to,for example..if my sprinklers go on at 6 am..i'll program them to run for 5 or 6 minautes..then again for
5-7minautes 15-30 minautes later..so they'd run at 6:00 then again at
6:15 or 6:30 each day they were programed to run...

another thing to consider is the type of grass you have..if it's some-
-thing like bluegrass, it will use more water then some other types..

lastly,..as for how many times a week you should water,..my best advise is to water every other day.. when a lawn is watered too often
the roots don't penetrate down into the soil and require alot more
water..and will dry out much easily...this is also true for many perennials..
watering too often is also what will help encourage plant diseases and
pests..this is especially important in more humid regions of the country..

Your watering practices will depend on the type of grass you have.
Lets say you have St Augustine grass which is popular in the hotter regions.
During the warmer seasons you need to apply 1/2 to 3/4 inches of water twice a week.
This will establish a deeper root system.

There are simple calibration tests that you can use to see how much water each zone is applying.
here is a link that will tell you how it is from our local extension office here in FL but will work for any system

Running the the sprinklers in the early morning will help to prevent fungus watering later in the day you waste a lot of water due to evaporation.

Established "woody ornamentals" (these would be your various bushes) only need to be watered if there has been no rain for 2 weeks.

One thing you need to check is are there any watering restrictions for your area.
