Although I'm certain most people understand what happens to golf courses in the winter, I thought I would detail a few things. If you notice more divots and/or ball marks on the greens, please don't assume this is due to improper maintenance. Bentgrass doesn't grow much in the winter (Bermuda not at all) and this growth is what allows divots to heal. To help keep the course in prime condition, please always remember to fill your divots with the supplied sand and repair your ball marks on the green.
Always keep our course in as good, or better, shape than you found it!
