How Does Liquid Aeration Work?

Liquid aeration acts differently from manual or core aeration. Liquid aerators pour a solvent over the grass instead of digging holes in the surface. It helps break down soil compactness and allows more air, oxygen, water, and nutrients to develop healthy root growth. While roots grow deeper, more critical nutrients become easily attainable. Thus, you get an excellent healthy lawn and greener grass.

The force behind these formulas is an active component close to lauryl sulfate that you use in soap. This ingredient is called an anionic surfactant as it contains a negative ionic charge.

Should you aerate clay soil?

Yes, you should aerate clay soil because it helps to allow air, moisture, and nutrients to move freely into the root area, restraining poor drainage and water accumulation.

When is the appropriate time to aerate your lawn?

The best time for aerating the lawn depends on the type of lawn grass. For example, cool-season grasses ( Kentucky bluegrass) should aerate in the fall. In the growing season,  temperatures are more relaxed, and weeds are under control.

Spring is the best time for aeration of the warm-season grasses ( Bermuda, centipede). Most of the lawns only require aeration once per year.

Exceptions always have- if the lawn ground is tight due to new construction over the lawn site keeping all the equipment of buildings. As a result, aeration will need to ensure water in the roots of freshly laid sod.

While the ground is damp, aeration is fine, but it should never be done after heavy rain. You’ll end up with a muddy mess that can make it too hard for the lawn to regain.

How to apply liquid aeration soil loosener?

To apply liquid aeration soil loosener, firstly, you must make the square footage of your yard. To make the square footage in your yard, you have to divide your house into rectangular sections.

Then, after measuring each section, multiply the length with the width of every section. The result will ensure you the square feet for each section.

Next, getting the total square feet of your yard, simply add all the areas of these sections.

The next thing is to find the compaction level of lawn or garden soil and the kind of sprayer you want to use. Then, look at how much liquid that sprayer can hold. Then, see how many square feet you can cover with that amount of liquid in the sprayer.

The concentration of the liquid aerator needed to be diluted with solvents or water. Read out the instructions attached in your preferred liquid lawn Aerator to find out the directions on how much solvents need to mix with it.
