Why Irrigation is Necessary for a Healthy St Augustine Lawn

The soil is the stomach of the plant - it digest plant food. Without water, the stomach dies and so does the grass.

The Soil is a Thriving Living Community

Your lawn is an ecosystem - a community of living organisms and non-living components that interact to produce nutrients and to consume nutrients - a cycle of life. St Augustine grass and soil microbes are the living elements. Soil, water, air, and organic matter are the non-living elements.

Lawn Ecosystem: Water is Critical

All the elements of this ecosystem are important, but water is the one element that when in short supply, the cycle of life stops and the ecosystem collapses. Soil microbes need water to move around and to keep their fragile bodies from drying up. Water is critical for the enzymatic digestion of organic matter and the transportation of nutrients. It also regulates the temperature of the soil and provides the removal of excess wastes from the ecosystem. Remove the water from the ecosystem and everything comes to a screeching halt - the ecosystem collapses.

You can grow a lawn without soil - it is called hydroponics. You can grow a lawn without organic matter and even soil microbes. But without water, the cycle of life stops and the lawn will perish.

The Problem Is Our Sandy Soil

Our Pinellas sandy soil does not store or hold water for any length of time. Our sandy soil is like a bucket with holes in the bottom - you fill it up and the water leaks out the bottom. This takes about 72 hours.

Real Life Example: If it rained on Tuesday morning, by Friday afternoon your lawn will be water stressed and on Saturday your lawn will go into survival mode - photosynthesis stops, leaves curl up and die, removing excess leaves and shoots, all growth stops - all to conserve water. Your lawn is dying - the cycle of life has been interrupted. Unless it rains, the lawn perishes.

But, had the automatic irrigation system ran on Thursday morning, the ecosystem would have never had a water shortage. The St Augustine lawn would continue photosynthesis, producing more leaves, more stems, more shoots and more roots. The cycle of life would have continued making nutrients and the lawn would keep consuming nutrients to provide the energy to grow, recover and thrive. It is healthy lawn.

Sandy Soil Solution

The solution to the low water holding capacity our sandy soil is an automatic irrigation system. An automatic irrigation waters on a regular schedule preventing water shortages in the ecosystem.  With a continuous supply of  adequate water, the cycle of life continues, uninterrupted, making nutrients and consuming nutrients.

A St Augustine lawn is more than grass - it is living, breathing ecosystem made up of living and non-living elements. Within this ecosystem is the cycle of life for the lawn - the making of nutrients and the consumption of nutrients. All of which is dependent upon water - no water, no lawn. But with an irrigation system, you can grow a beautiful healthy lawn in Pinellas County.

Rick Orr is the creator of Iloveturf.com, Owner/Operator of APL Pest Control and a graduate from VA Tech in Agronomy (Turf Ecology).  

Since 1980, Rick worked in the green industry, mostly with golf courses, resorts and large communities. Rick worked as a Golf Course Superintendent of Fripp Island Resort, agronomist for Seaside, FL and the spray tech for Vinoy Golf Course. Rick has been certified as an arborist, landscape and irrigation contractor and adjunct professor for Environmental Horticulture (SPC) in Pinellas County.  

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.
