It’s that time of year again.

Time to break out the aerator on warm season turfs like bermudagrass and zoysiagrass.

Core aeration, sometimes referred to as core aerification, is a process where a machine makes multiple passes over a lawn, pulling cores of dirt ranging from two to four inches deep and deposits those cores on top of the turf.  The holes left behind help to reduce compaction and open up the soil to be able to absorb water better and increase air flow at the base of the plants. The cores of dirt left behind are then broken up as the lawn is irrigated forming a thin layer of soil over the thatch just below the canopy of the turf.  The general premise is that the soil covering the thatch will help it decompose faster.

Thatch is the dead grass, and other organic material that builds up on top of the soil surface usually left behind by mowing.  Too much thatch can prevent water from reaching the root zone of the turf and reduces air circulation to turf roots causing decay.  Excess thatch can also create a moist environment where disease can grow and infect healthy turf.  Keeping thatch layers at acceptable levels is essential to the overall health of your grass.

This year we are using a newer product in conjunction with core aeration.  It is a liquid product made by Greene County Fertilizer Company by the name of N-Ext D-thatch.  It is described as a “Thatch Digester” that is designed to reduce the thatch build up in lawns.

“N-Ext D-thatch focuses on composting thatch faster by encouraging microbial activity at the soil surface and increasing heat.  This exothermic release by increased soil activity will break down thatch from the soil level up.  Thatch is quickly reduced and organic matter is captured as a food source for your turf.”

Our goal in combining conventional mechanical aeration with a liquid application of N-Ext D-thatch is to ensure that your lawn gets the most benefit and performs at its peak.  For this summer we are offering 50% off N-Ext D-thatch applications when completed at the same time as a core aeration on warm season lawns.  To take advantage of this offer, give us a call and mention this blog.

If your lawn is made up of cool-season turf, such as Fescue, we recommend that you wait to mechanically aerate the lawn until later in the season in conjunction with overseeding efforts.  Core aeration this time of year in fescue only serves to tear up the turf.  We can, however, apply N-Ext D-thatch to Fescue with great results this time of year.  In fact, if your fescue has a thick layer of thatch and is prone to disease each year, we would strongly encourage an application.  Again, anything that removes the thatch and opens up circulation is going to naturally deter disease issues.
