Lawn Watering Infoline - July 24
Welcome to the lawn watering infoline. Based on current weather conditions, your lawn needs about one & three quarter inches of water this week. Temperatures and are forecasted to cool for the next couple days, then go to triple digits, so keep this in mind when adjusting your watering times.
Different sprinklers apply water at different rates, but as an approximate guideline, you would need to run standard spray sprinklers a total of about 72 minutes for the week. Rotor sprinklers tend to apply water more slowly, so they need to run around 173 minutes over the course of the week to apply this same amount of water. And if you have multiple stream rotators, you will need to run them for 270 minutes to achieve one & three quarter 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 this week, you would need to run spray sprinklers for 18 minutes each watering day to apply the needed amount of water. Rotor sprinklers would need to run 43 minutes on each watering day and rotators 67 minutes each of the 4 watering days.
Additionally, instead of applying all the water in one cycle, consider breaking it up into three shorter cycles separated by an hour or so. That would mean running spray sprinklers 6 minutes each cycle, rotor sprinklers for 14 minutes and multi-stream rotators 17 minutes. This will help the water absorb into our tight heavy clay soils.
Please keep in mind this information applies to lawns only. Shrub areas need less water than lawns, and usually benefit from less frequent, deep watering.
To help you make the most of your watering, also consider the following tips:
Schedule your sprinklers to run before the sun comes out. If you complete your 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, which may include adding more or larger emitters as plants grow.
