Maybe I can try it again this week.
Soil temp here is 35 under turf.
That is an excellent point...
It takes a long time for the CG to germinate in the "Hot Spots" of a lawn, and almost never in GOOD lawn,,, even though the soil temps are above 60 degrees for the entire summer...
There's a place for numbers and then there is a place for reality in the field...
