As fall 2001 approaches it is time to get the golf course ready for winter. This
will require increasing the height of cut for all the grass on the
course, with the exception of the greens.
After the greens heal from the aerification; we will start lowering the
height of cut. This will result in an increase of green speed and smoothness.
We will also resume our rolling, top dressing, and verticutting.
Aerification went well this fall. The increase of heavy topdressing has
greatly improved the profile of the greens, especially on the backside. As you
may know, the backside greens are clay-based, and the front greens are
sand-based which are built to U.S.G.A. specifications. I can remember a time
when the back greens were less than 20% sand. Now, I think its safe to say
that they are about 45% sand and improving each year.
There have been many questions about how and why we aerify the way we do.
The backside greens are clay-based and that makes them firmer than the front.
By the greens being firmer, it allows us to double aerify without hurting the
turf. By double aerifying, we are removing twice as much clay and replacing it
with sand. This will greatly improve the profile of the soil that will in turn
improve the quality of the turf.
The front greens that are sand become very loose and rough after the first
aerification. If we do not give the greens a week to become firmer and
smoother when we aerify the second time, we peel the turf and leave bare
places on the greens from pushing off the plugs.
We are following the guidelines set by the U.S.G.A. for aerification at the
September 2, 1999, meeting. I would like to remind everyone that aerification
is a necessity, and to please bear with us during this process each year.
Aerification is preventive medicine for the greens, and will only insure their
survival. I would like to apologize for any inconvenience to you during this
process, and thank you again for all your cooperation. If you have any
questions about this process, feel free to ask.
