Rain does not wash away fertilizer. The lawn is a filter plant and everything that lands on a lawn, stays on the lawn

It is Science

The science behind why the rain does not wash away the fertilizer is basic organic chemistry - the magnetic bonds between charged particles. It is like a magnet and iron filings - organic matter (grass leaves, debris, and the soil microbes) are magnets and the fertilizer spray is iron fillings. When we spray your lawn the fertilizer is tightly held onto the organic matter by magnetic bonds. This magnetic bond cannot be broken by rain, so the rain cannot wash away the fertilizer.

Water in after Application

The label requires that our spray be watered in after applied to the lawn. This helps spread the fertilizer over more surfaces. The more surfaces, the more the magnetic bonds. Rain or irrigation after our application helps our fertilizer to not wash into local waterways or wash away.

Why Does the Lawn turn Green after the Rain?

Did you ever notice how lawns turn green after the rains? If the fertilizer washed away with the rains, the lawn would turn yellow, but it doesn’t. Why? Because the rain did not wash away the fertilizer!

Moist Soil Is Critical to Survival 

A dry soil starves a plant – a wet soil feeds a plant. A plant must have a moist soil to absorb the nutrients clinging to the organic matter. When a lawn is well watered – like after a rain - it can absorb more nutrients, be healthy and thrive. Whereas a dry lawn is yellow weak and often in a “survival mode” of just barely living. To take full advantage of lawn spraying you should be generous with the water.

A Tall Canopy Helps

Mowing at 4” or higher increases the amount of surface area in the lawn. The more surface area, the more magnetic bonds. To take full advantage of lawn spraying you should mow your lawn at 4” or higher.

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.
