I provide fert/chem service for a couple of school systems including their competition fields. In the past, their coaches and maintenance folks have attempted the overseed and performed poorly. The baseball fields are 419 tif and the softball is common bermuda. I hate overseeds on southern turf from the fact that it "drags" the spring green-up of the bermuda, but being that competition begins in February, overseeding is the norm. It appears that I am going to have to assume this task, so I am seeking advice on rye variety and seeding rate. I would like to find a variety that transitions out quickly in the spring and offers a good density in late winter.
