The school's man mows and paints lines. He told me that he put some perennial rye seed down on the sidelines at the end of last season. Until this year they had not done any fertilizing, weed control, topdressing, aerating or anything else for many years. They have a good irrigation system and it gets mowed often Spring through Fall.
I will be fertilizing and filling a few holes to put it to bed this year. The school will keep mowing as late in the year as necessary. It should look better next Spring than it has in a long time. With it now growing aggressively and having knocked out most weeds, next year should be easier with more fine tuning. There are a few areas with bentgrass I would like to take out next year. The last step for any project like this (for me) is "evaluate results and tweak plan for next year." I will be meeting with the athletic director soon to do that.
