Note: Despite producing a quicker result, there’s no scientific proof that liquid iron fertilizers make grass greener than granular iron fertilizers. They hold onto the iron particles until they’re absorbed by the grass roots. Reduced leeching– chelates in chelated liquid iron fertilizer prevent water from washing away the ions.As such, chelates ensure that iron doesn’t go to waste by preventing reaction with oxygen. Remember, grass roots can’t absorb oxidized iron. Higher Uptake Percentage– most liquid iron products contain chelates, which are organic molecules that engulf the iron particles to prevent oxidation.Some of these micronutrients (like zinc, copper, and manganese) improve turf growth rate, while others boost drought and disease resistance. Improved turf health– most liquid iron products are usually infused with other micronutrients that also boost turf health.Thus, you should only use this method for moss control if the grass is healthy and isn’t suffering from any stressors that might hinder quick recovery. Take note, though, that the recommended concentration (6-ounces per gallon of water) is usually too strong and will cause the turfgrass to turn brown as well. Liquid iron, being a fast-acting fertilizer, will eliminate moss at a quick rate. Faster moss control– iron fertilizers, when applied in excess are also known to control moss problems in lawns.By comparison, it’s harder to achieve even application of granular iron fertilizers, since it’s hard to tell which spots haven’t been covered yet. Fewer missed spots– when spraying liquid iron, it’s easy to know which spots you haven’t yet covered by simply checking for turf areas where the grass blades aren’t wet.

This saves lots of time, as opposed to granular iron fertilizer which has to be watered in to push the granules deeper into the soil. Easy to apply– you simply have to spray liquid iron on your discolored lawn to kick-start the greening process.Faster uptake via roots– what’s more, the iron that drops on the ground penetrates through the soil and into the grass root zone much faster than granular iron fertilizer.When spraying liquid iron, it coats the grass blades, leading to foliage uptake which is quicker than root uptake. Liquid iron is good for grass since it leads to faster greening compared to granular iron products. And if your lawn has turned to a pale shade (light green/yellow) due to iron deficiency, applying liquid iron is the fastest path towards recovery. With more chlorophyll, the grass looks greener (more attractive) and can easily create energy via photosynthesis.Įven better, is when the iron is applied in liquid form, as the above positive effects are realized faster. Iron is an important micronutrient for healthy turfgrass, as it facilitates chlorophyll formation.
