Lawn Watering Infoline - August 25

Hello and welcome to the Lawn Watering Infoline.

In an effort to help save water, as you speak with your friends and neighbors, mention this Infoline to them, especially if they use an automatic sprinkler system on their landscape. 
 
Based on current weather conditions, turf grass needs one and two thirds inches of water this week.  Additionally, the weather forecast is calling for temperatures to be cooling over the next week, so monitor your lawn and adjust your sprinkling accordingly.
 
Different sprinklers apply water at different rates, but as an approximate guideline, you would need to run standard spray sprinklers a total of about 66 minutes for the week.  Rotors apply water more slowly, so they need to run around 160 minutes over the course of the week to apply this same amount of water.  If you have multiple stream rotators, you need to run those for 249 minutes for the week to apply one and two thirds inches of water.
 
To determine how long to run sprinklers each watering day, divide the total minutes we’ve given by the number of days you will be sprinkling this week.  For example, if you water 4 days per week, you would run spray sprinklers for 17 minutes each watering day to apply the needed amount of water.  Typical rotors would need to run 40 minutes on each watering day and multi-stream rotators for 62 minutes each watering day to apply one and two thirds inches of water.
 
Additionally, instead of applying all the water in one cycle, break up the watering into three shorter cycles separated by an hour or so. That would mean running spray sprinklers 6 minutes each cycle, rotor sprinklers for 13 minutes and multi-stream rotators 21 minutes.  This will help the water absorb into our tight heavy clay soils.


To help you make the most of your watering, also consider the following tips:
 
If you haven’t done so already, aerating your lawn is a good way to get the water deeper into the soil, as well as oxygen. This will help your lawn in the hot days of summer.
 
Run your sprinklers before the sun comes out.  If you complete watering before 6 a.m., your sprinklers won’t have to compete with other water uses, and can also take advantage of the lowest temperatures of the day.  If you prefer evening sprinkling, wait until at least 9 p.m. when it has started to get cooler, and breezes have died down.
 
In addition to adjusting your irrigation times, remember to give your sprinkler system an occasional checkup.  If you haven't observed your system operating lately, turn it on and make sure sprinklers are all facing the right direction and functioning properly.  Areas served by drip systems need maintenance too, checking to make sure emitters aren’t clogged and are watering the intended plant material. 

As a reminder, if you are a Medford Water Commission customer, we offer a Free Sprinkler Survey in which we provide an overall evaluation of your sprinkler system and make recommendations for any improvements. Call 541.774.2436 to set up an appointment.  

For a guide to help you schedule your sprinkling, you can download our Sample Lawn Watering Schedule or call 541.774.2436 to have a copy mailed to you.

There is a wealth of information on conservation and landscaping on the website, which we hope you will find helpful. If you have any questions or comments, or would like more information, email us or call 541.774.2436.
