How often should I water my lawn?

Question:

How often should I water my lawn?

Answer:

Most lawns in Iowa require 1 to 1½ inches of water per week.  When watering the lawn, apply this amount in a single application or possibly 2 applications 3 or 4 days apart.  Avoid frequent, light applications of water which promote shallow rooting and lush growth.  Lush, shallow-rooted turfgrass is less drought tolerant.  It is also more susceptible to pest problems.  To determine the amount of water applied by a sprinkler, place 2 or 3 rain gauges within the spray pattern.
