Characterizing Cool-Season Putting Green Management

Species preference

Thanks for your interest!

This survey is a follow up to an article we at Purdue published in Golf Course Management magazine last fall related to the cultural needs of creeping bentgrass and annual bluegrass putting greens throughout the cool-humid region. It should only take about 5-7 minutes of your time to complete.

Please answer the following questions about the putting greens at the facility you manage, the major cultural inputs (e.g. how many times do you mow, topdress, use PGRs, etc.) and your preference for your surfaces.

*****Please note:If you manage > 18 holes please normalize your answers for 18 holes. Meaning if you have 6 acres of putting greens over 36 holes base your answers on 18 holes.*****

Questions regarding this survey should be directed to Dr. Cale A. Bigelow (cbigelow@purdue.edu)
