The answer depends on what type of soil you have, shade/sun conditions, type of plant and how much water "Mother Nature" provides. The time of year (the season) makes a big difference too. Here are some general guidelines you can use, but if your plants aren't healthy, improper water is the first indicator I look for to diagnose a problem. The winter is a tough time on plants as lack of rain and cold temperatures (which desiccate the plants) create numerous problems.
Watering is a day-to-day function. Mother Nature provides some and we do too. If you are serious about saving water and keeping your plants and turf looking their best....it's a full time job! Automated Irrigation systems that are properly installed and managed can make the job much easier and "Hassle Free".
Winter - Lawn, an inch (Automatic Irrigation: Rotors 20 minutes, Pop-ups 10 minutes) every four weeks. Beds, an inch every week.
