: How long do you do outdoor watering?
You haven't said WHAT you are watering outdoors, so here are some rules-of-thumb to go by:
Concrete/Asphalt - no watering unless you want it cleaned or you want to walk over it barefooted on a hot summer day. Water does not help it grow.
Dirt - no watering unless you want to stop dust from blowing around. Water does not help dust grow.
Gravel - the perfect yard. Water only in moderation. Don't expect any results from that.
Sequoia Trees - if you happen to have these in your yard, don't worry about them. They got along fine in your yard hundreds of years before you and water hoses showed up.
Weeds - no watering. There is no way you can kill them, so why waste water?
Newly planted grass seeds - no watering. If you water, they will just turn into lawn and then you'll have to water all the time.
Lawn (brown) - no watering because it will just die anyway.
Lawn (green) - wait until lawn turns brown and then follow the instructions for Lawn (brown).
Hope that helps.
