Pick What Fit Your Home
The best time to water lawn is in the early morning. Watering in the morning is best because this allows the water to trickle deep into the soil and allows the leaves of the grass plant to dry before the water evaporates as it gets warmer in the day. If you cant water in the morning the night time is OK just try to do it earlier! (better to water than not water at all).
You need to water at least once a week for at least an hour, this generally provides 1″ of water to the roots (a tuna can height) (exceptions: 1. when you seed & 2. if you have an automated system).
The deeper the roots- the less often you will need to water- and a healthier lawn withstands drought. Deep watering encourages deeper roots as they grow deeper into the soil to search for water. Deep roots enjoy the lower soil temperatures during the heat of the summer and less fluctuations in moisture levels and temperature.
All lawn areas require 1”- 1.5″ per week. This is best done in one to two watering’s per week depending on your soil type. The trick here is to water deeply so that the roots grow down deeper into the soil to chase the water, thereby leaving more soil above them to protect them during periods of dryness and excessive heat. (Sandy soils drain quicker, therefore must be watered more frequently.)
Use a timer
Hose end or hose-bib timers are available at major retail hardware stores and allow you to water your lawn while not at home. Simply attach to your tap before you attach your hose. When you leave in the morning, set your sprinkler out at the desired location, turn the timer on to 60-120 minutes and leave for the day. You can rest assured that the lawn will get the water it needs and you don’t have to remember to shut it off.
