A smooth putting surface is the visible result of decisions made well below it. At Atwood Hollow, 007 and A4 creeping bentgrass are managed with an eye on healthy roots, consistent firmness and the realities of northern Illinois weather.
Build the rootzone for the long game
A sand-based USGA-style rootzone is designed to balance drainage, air space and water retention. Sand selection starts with a laboratory particle-size analysis, not color or feel alone. The distribution needs to fit the rootzone specification and remain compatible with the existing profile. Too many fines can reduce infiltration; an overly coarse or mismatched material can create layering and interrupt water movement.
Light, frequent topdressing helps dilute organic matter and smooth the surface. The best sand is one whose particle distribution works with the material already in the green. Brush or water it in thoughtfully, and adjust frequency to growth, weather and play.
Measure moisture, then read the turf
Time-domain reflectometry (TDR) meters give the team a repeatable view of volumetric water content. A working target of 14%–18% VWC is a useful starting point, not an instruction to water every green identically. Probe several locations and depths, track trends, and consider shade, wind, drainage and the plant’s condition before hand-watering dry spots.
Prepare for ice, not just snow
Winter ice encasement can restrict gas exchange and damage turf, particularly during prolonged freeze-thaw cycles. Fall preparation includes managing surface drainage, reducing low spots where water collects and keeping snow and ice observations current. When conditions warrant, a trained team can evaluate removal or venting methods against the risk of physical damage. There is no universal safe number of days under ice: species, temperature and site conditions all matter.
“The best surface is one the plant can sustain, not just one that is quick for an afternoon.”— GRANT CALLAHAN, CGCS & PGA DIRECTOR OF GOLF
