Areation Core can take place any time during the year when turfgrass is actively growing and soil moisture levels are abundant enough to allow tine penetration
In addition to regular lawn maintenance activities, such as mowing and fertilization, it is often necessary to implement secondary cultural practices to help keep turf grass at a consistent level of quality. Core aeration is regarded as one of the most beneficial practices available to turf grass managers. This service involves the mechanical removal of soil cores with tines or spoons from a lawn area. The cores generally range in diameter from 0.25 – 0.75 inches and can penetrate up to 4 inches into the soil depending on ground moisture level. This action pulls “plugs” out of the ground and the soil is then left on top of the grass to serve as topdressing.
Numerous benefits can result from this important practice. As the cores are left on the grass, they break down into organic topdressing which helps reduce thatch layers. Thatch layers make for an almost impenetrable barrier, disallowing water entry into the earth. In turn, this lack of water makes for weak turf grass roots and limits strength during stress such as drought conditions. Thatch also reduces the efficacy of herbicides and insecticides, sometimes not allowing the product to work at all.
In another way, core aeration helps release toxic gases from the soil, which may affect turf roots. Oxygen intake is vastly improved and the result is vigorous growth and again, a stronger root system. The holes rapidly fill with feeder roots and increased shoot growth occurs.
A further benefit of core aeration is improved water intake, especially in the soil, in addition to accelerated drying in persistently wet soil. Soil compaction from foot traffic as well as natural settling conditions begins to noticeably diminish after a routine program of coring is carried out.
Lastly, there is a marked response to the intake of fertilizers. By supplying the roots with necessary nutrients, the quality of the turfgrass becomes thicker, healthier and improves in color. The result…A more weed-free lawn!
When to Core Aerate
Core aeration can take place any time during the year when turfgrass is actively growing and soil moisture levels are abundant enough to allow tine penetration. When choosing between spring and fall, autumn is generally considered to be the best time to incorporate this beneficial practice into your turfgrass management program.
