The Golf Maintenance Department will aerate greens on all the bent grass golf courses this month.

“By core aerating greens, water and air movement are allowed throughout the greens profile. Aerating the greens will promote the overall health of the courses’ turf”, Golf Course Maintenance Manager Keith Ihms said. “Aeration also works toward removing thatch and building stronger root systems”.

The main purpose of pulling cores is to manage the thatch layer on the greens; thatch layer is mostly made up of dying and un-decomposed leaf and grass material. “By pulling cores we are removing some of that material and preventing it from building up to an unacceptable level”, he said.

Thatch causes the greens to become soft and spongy, which can make for poor putting conditions. When thatch gets to this point it also can become a problem dealing with the other issues it causes, such as fungus growth, mower scalping and “localized dry spots,” which will not absorb and retain moisture.

“Aerating creates openings in the surface for water and nutrients to be absorbed, as well as the sand that will be used to smooth the putting surface and fill in voids and amend the green profile”, Ihms said.

A second sand topdressing will be necessary a week or so after aeration to help fill in aeration holes and smooth the surface.
