Do Not Turn Off your Irrigation During the Rainy Season

Turning off the irrigation and then forgetting to turn it back can disastrous for the lawn

Many Forget to Turn The Irrigation Back On

I know it looks silly to have your irrigation run while it rains, but that is about all it is – visually odd. It is raining and the irrigation is running and it looks silly.

To not look silly, many turn off their irrigation systems during the rainy season. And many forget to turn them back on again until they notice the lawn has dead brown spots from lack of water.

It Never Rains Enough to Keep Your Lawn Alive

 Our sandy soils determine how long a lawn can survive between watering not how much it rains. In Pinellas that is about 72 hours. Everything would be fine if it rained every 72 hours – but it doesn’t.

Scattered Thundershowers Grow Scattered Lawns

If it rains 2” on Monday, by Wednesday your lawn needs water. By Friday your lawn is starting to die. Your lawn needed water on Wednesday, and even though it may rain on Saturday, you have already lost a portion of your lawn to water stress. Repeat this scenario several times and the once lush green lawn is now a patchwork of weeds and turf.

You’re Not Wasting Water

Each time your water your lawn, your puny little irrigation system is pumping out 800 gals of water – a single thundershower dumps about 4000 gals on your lawn. When you irrigate while it is raining, your irrigation water and the rain are soaking back into the ground. It may be redundant to irrigate while it rains, but all the rain and the irrigation water are going back to the same place – the aquifer.

It Rains 4’ of Water Every Year

A single thundershower dumps about 10 billion gallons of water on Pinellas County. In a year, about 540 billion gals of rain falls on Pinellas County to recharge surface and groundwater. That is at least 5 times the amount of water used for irrigation purposes in Pinellas County.

No Need to Worry about Over Watering

I have never seen a lawn die in Pinellas County from water but I have seen many die from the lack of it. One good quality of our sandy soils is that it drains fast making overwatering your lawn nearly impossible. Our sand soils drain at over 10” per hour. Overwatering your lawn is like trying to fill up a bottomless bucket to overflowing - nearly impossible. Overwatering is not lethal to your lawn but underwatering your lawn is lethal - so if you are going to err, err on the side of overwatering.

Too Many Find Out Too Late

Many homeowners look conscientious about the environment turn off the irrigation during the rainy season and learn too late that cutting off the irrigation was not such a good idea.

My best advice: Never turn off your irrigation system

Home Pest Control came naturally. Entomology (bug science) was part of agronomy studies. Nearly every indoor pest problem starts outdoors. Crossing over to home pest control from lawn spraying was a natural process – the technology, methods and materials used for home pest control are modifications of the ones used for lawn spraying. 

The results of that work is a one of the top rated pest control companies in Pinellas County – APL Pest Control. APL Pest Control is a family owned business serving residential and commercial properties in Pinellas County, FL.
