Basic Watering 101: How many days a week should I water?

How many days a week should one irrigate?

There is no set answer that applies to all. I can tell you that it is better to irrigation fewer times a week with longer durations then it would be to water a few minutes everyday.

A formula would be:

PR / D = RT
Desired precipitation amount per each zone divided by number of days you want to irrigate, this will give you your station run time. Do this for each zone and constantly make adjustments as the weather changes. Remember that not all zones will need the same amount of water due to different hydro zones with each property.

As a basic rule of thumb I usually water 3 days a week. Monday, Wednesday & Friday or Tuesday, Thursday & Saturday. You want to try to avoid watering the morning of when your lawn is mowed.
