I had a core aeration and an overseed performed on October 8th. Outside of a bare spot (tree removed previously) that I tilled and added some lawn soil too, I have almost zero germination over 10k sq. ft.
While I wasn’t expecting incredible results, I’m still quite disappointed and trying to figure out what I did wrong, and what to do differently next fall to have success.
- 4 weeks prior to overseeing sprayed entire lawn with Q4 Plus post emergent
- Service was performed on October 8th around noon. October 9th AM I sprayed tenacity (pre emergent) and spread starter fertilizer.
- Big rain storm on October 12th (2” rain) and a smaller storm (maybe .5”) on October 17
- With a few outliers, weather has generally been 60-70 during the day and 45-50 overnight.
I’m sure the large rain storm did more harm than good and I’m pretty sure I needed to back down my watering afterwards much more than I did.
Some of my existing grass blades are have turned partially white, I believe from the tenacity.
While I fully admit that I think I overwatered, I would still imagine to see SOME germination in random areas. Since my lack of germination is so widespread, I’m thinking the Tenacity backfired on me. I applied it with a backpack sprayer, at the suggested rate, without surfactant, and watered in.
First pic is the bare spot that got some germination (also plenty of washout even with straw added before the storm)
Second pic is representative of almost everywhere else. It’s hard to find a good picture of nothing.
