I am a homeowner interested in renovating a 200' x 60' lawn area on my 2 acre lot located beneath 4 mature pecan trees in suburban Atlanta . I have recently trimmed the pecans to maximize direct sunlight in summer, but at best, this is a mostly shaded area 7-8 months/year. The area contains some fescue, centipede and bermuda along with some bare dirt patches. The area borders bermuda lawn to one side and centipede to the other. The area will require constant care in that gets much traffic, football, baseball, etc.... I have just purchased a pull-behind 40" plug aerator and 175lb spreader and would like to put the equipment to work. The area will be irregated with my cast iron walking sprinkler. I would like to begin the renovation right away (December-January). Is there a seed that I can begin with such as a annual rye at this time of year? Or, should I just hold off everything until next fall? If I want to begin renovation now, what type of seed is best? What type of results can I expect? If the rye works now, can I then plan on an overseeding of fescue in the spring as my final turf?
