Should I remove soil plugs after aeration?

After core cultivation, many homeowners wonder whether to remove the soil plugs scattered throughout the lawn. Along with non-intuitive conclusions, they should not be removed. They break down naturally and, within a very short time, usually 2-3 rainfalls, fall into the soil where they become a source of nutrition. If removed, these beneficial substances would be lost, and a great deal of unnecessary work would be created. The temporary visual effect will not last as long as most expect.

Rainfall is a key accelerator of plug decay. Moisture softens the clay cores, and microbial levels increase in moist conditions. Within a matter of days, earthworms begin to break down the material, distributing it through the soil profile. This biological process integrates nutrients more deeply than normal surface fertilization can provide. Mowing the plugs after several days of drying will speed up incorporation without damaging the equipment.

Worries regarding the appearance of plugs subside rapidly when the natural process occurs. While easily observed, they disintegrate quickly under foot traffic in a few days. Rain turns them into fine particles, which nest in the blades of grass. Within 10-14 days, the visible evidence is wholly disappeared in moderately rainy weather. This temporary period is outweighed by the permanent effects in the soil which are developed below the ground.

The benefits of using retained plugs are numerous, and these benefits are compounded year by year. Each aeration cycle is successful in materially increasing the amount of organic matter in the topsoil. The surface is spongier, allowing water to be absorbed more effectively and maintained with great ease. Depending upon the soil and other factors, the average lawn will require from 20 to 30% less irrigation water after three seasons of use. Test soils reveal increased nutrient availability with no additional fertilizer applications.

Please do not disturb the plugs with rakes or heavy equipment, as this disturbs their structure and effectiveness. When nature is allowed to take care of itself, the best results are achieved. To get the maximum benefit, leave the plugs in place and lightly topdress with compost. This is beneficial to the natural cycle of nutrition and promotes the establishment of durable turf. All professional services generally recognize this means of cultivating the turf as the best and most lasting method.
