Lawn Watering Infoline - August 15, 2018
Hello and welcome to the Lawn Watering Infoline. Today is Wednesday, August 15th. In an effort to help save water, mention this Infoline to your friends and neighbors, especially if they use an automatic sprinkler system to water their landscape.
The summer heat is here! Now is a good time to raise the mow height on your lawn mower. We recommend mowing lawns at a minimum of three inches in the heat of summer to ensure the turf stays cool.
Based on current weather conditions, turf grass needs just under one and a half inches of water this week. Additionally, the weather forecast is calling for temperatures to remain warm over the next couple of days, so monitor your lawn and adjust your watering 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 58 minutes for the week. Rotors apply water more slowly, so they need to run around 138 minutes over the course of the week to apply the same amount of water. If you have multi-stream rotators, you need to run those for 216 minutes for the week.
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 watering this week. For example, if you water 4 days per week, you would run spray sprinklers for 14 minutes each watering day to apply the needed amount of water. Typical rotors would need to run 35 minutes on each watering day and multi-stream rotators for 54 minutes each watering day.
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 5 minutes each cycle, rotor sprinklers for 12 minutes and multi-stream rotators 18 minutes. This will help the water penetrate deeper into the soil.
To help you make the most of your watering this season, also consider the following tips:
Run your sprinklers before the sun comes out. If you complete watering before 6 a.m., your watering won’t have to compete with other water uses and will take advantage of the lowest temperatures of the day. If you prefer evening watering, wait until at least 9 p.m. when the temperature has started to get cooler, and breezes have died down.
In addition to adjusting your watering 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, which may include adding more or larger emitters as plants grow.
