Healthy to the core

Proper aeration can breathe new life into turf.

Soil compaction and thatch buildup are two of the biggest obstacles you face as you care for turf. Just walking or driving across turf to mow it can compact the soil. And thatch is going to build up simply as a matter of the nature of some turfgrasses. Under these conditions, water, air and fertilizer can't get through to the turfgrass roots, which then suffer. The result: Patches of your turfgrass may begin to die; runoff increases and dry spots appear. The solution: aeration.

Core aeration is a great way to improve the quality of your turf, and it's important to make it part of your regular turf-maintenance plan. It pulls plugs out of the soil, letting in the water and oxygen that turf requires. The benefits of core aeration include improved water penetration and decreased runoff; increased fertilizer movement to the root zone; promotion of root development; and increased oxygen intake by the soil.

Aerators are available in a variety of types and sizes, and, as is the case with any type of equipment, you should evaluate your needs in order to select the best one for your business.


Before selecting an aerator, you should determine the size and placement of tines. If you want to remove a lot of material from the soil (to remedy heavy compaction), you should choose an aerator with large-diameter tines that are close together. Some aerators are equipped with interchangeable tines, which is appealing if you have a varying degree of compaction or thatch problems on your properties. Also look for aerators with adjustable spacing, which allows you to customize one aerator to fit a variety of needs.

Push or pull

While pull-behind aerators can generally cover more square feet per hour, walk-behind aerators are sometimes more practical for landscape contractors who need equipment to fit through gates and maneuver around trees and flower beds. If you plan on using an aerator on your larger, commercial accounts, a larger aerator can save you a lot of time. However, if you need to use one in a client's backyard, you'd be better off sacrificing a little time by using a narrower unit that fits through the gate.

Whichever you choose, look for versatility. Manufacturers are making aerators that you can adjust to fit all your needs. Find out exactly what those are, then make your selection.
