Liquid Iron Lawn Application Service

Removing dandelions and other broadleaf weeds, such as clover, plantains, and thistle from your lawn can be a tricky task, as they often contain strong taproots that make it difficult to pull them up by the hand. To effectively control the spread of these weeds, Organic Lawns by LUNSETH utilizes liquid iron (i.e. chelated iron), a post-emergent solution for some broadleaf weed control. Liquid iron can kill weeds like dandelions and moss in one application, but 3-4-applications applied 2-4-weeks apart is necessary for stubborn weeds such as thistle, clover, creeping charlie, and plantains.

Liquid iron for lawns (also known as FeHEDTA) is iron that is bound to a chelating agent, which makes it disguised as an amino acid and readily available to plants.  Some broadleaf weeds (dicots) think its food and have no sensors to shut off the chelated iron, resulting in weeds absorbing too much iron (iron oxidation) and dying as a result.  While grass (monocot), on the other hand, takes in just the right amount as a valuable micronutrient and stops when it is has had enough.

Chelated iron provides roots of grass blades with the iron required to produce chlorophyll, the green pigment that gives plants their color— thus broadleaf weeds turn black and die, while the surrounding grass will green up.

How is Liquid Iron Made?

Liquid iron is iron that has undergone chelation, a chemical process that binds the iron molecule to another substance. This process seeks to make iron more similar to naturally-occurring dietary sources, which in effect makes the iron easier for plants to absorb. Plants can take liquid iron in directly through their leaves rather than their root systems alone.

Applying Liquid Iron To Your Lawn

Organic Lawns by LUNSETH applies liquid iron around the time dandelions begin to bloom and to other broadleaf weeds through subsequent applications. When these weeds are exposed to liquid iron, their tissues oxidize—causing them to become dry and change color. Liquid iron can take 20 to 60 minutes to dry and once an appropriate amount of time has passed, children and pets are free to safely step foot back onto the lawn. 

When applying liquid iron, lawns may experience a slight discoloration. However, grass unlike weeds rebounds quickly due to the photosynthesis process, helping you achieve a greener and healthier-looking lawn in no time. 

Liquid Iron can be a helpful component in any organic lawn care program, as it serves a dual purpose: targeting broadleaf weeds while providing a beneficial nutrient to your grass.
