Today, I scheduled the delivery of the topsoil, borrowed a backpack sprayer and as a final sanity check, followed FlyingFish's advice to do a bit of homework on how Tenacity impacts fine fescue.
To quote the Tenacity label for new seeding/ new lawn establishment:
Considering that the SS6000 mix is 4/5 by weight of fine fescue, looks like Tenacity is a no-go for me.Apply Tenacity at 5-8 fl. oz. per acre prior to seeding or post seeding of tolerant turfgrass species listed on this label, except fine fescue. Tenacity may reduce density of fine fescue seedings. Tenacity can be used on grass seed blends that contain less than 20% by weight of hard or fine fescue.
What can I do at seed down to battle germinating weeds besides spending 3hrs a day after work hand picking them? There's got to be another way... right?
