Hi folks,
Looking for recommendation here....
Last few years Poa Annua in my yard has gotten worse. By the end of last summer, i was left with a yard that had a few larger bare spots, and then throughout most of the yard are clumps of decent grass with bare spots - all over.
Here is what i did:
Im in massachusetts...
A full dethatching, scarifying, and then aerating (in september). Bagged it all.
I put down first treatment of Pendulum2G in late september. Then about 6 weeks later i put down a second treatment.

With spring approaching, trying to figure out what is best. My yard is in bad enough shape that i need to seed, and seed heavy. its too bare in too many spots for it to ever fill in (with anything but weeds). So, what is recommendation for spring/fall? I know the Poa is lying there waiting to strike...but...
Would a heavy seeding in the spring (april), coupled with Tenacity to try and prevent poa growth bet recommended?
Then, in the fall, depending on how the grass took, get after the Poa with pre-emergents?

Somehow i need to get back to a fuller lawn before i can really fight the Poa. In prior years, my lawn never ended up so bad....it generally looked pretty good for the whole season but this past year i really got my but kicked.

I'm ready for a multi-year battle, but cant stand looking at a yard with such baren-ness...!

thanks for any inputs/suggestions.

Just a note to be extremely cautious where you get your topsoil from!

It’s been nigh on 6 or 7 years but the pain is fresh: I was not aware the load of topsoil I had delivered by a reputable seller was coming from a farm infested with wireworms.

Turns out wireworms are highly sought out by wild turkeys. Talk about destruction!

As I said, 6 or 7 years but the pain is still VERY fresh …

If I ever have to do something like leveling ever again, I’m going with sand!

Seeding ornamental turf in Spring is tough; one is sorta fighting nature which always wins …

Here are some notes from last threads on this topic that I copied and pasted into my own notes, hopefully they are of assist to you:

Poa - What to do?


From Suburban Jungle Life Weds MAR 20, 2019:

this timing of products is only for fescue.

I apply meso (Tenacity) at 0.184floz/M
NOTE: (x 2 = 0.368floz OR TRANSLATES INTO 10.883 mil / 2M sf PER 4 Gal Sprayer Tank
and etho (Poa Constrictor) 1.5floz/M the day of seeding.
I seed once summer heat breaks but not long after. If you seed late, poa will have germinated already.
Etho is safe 2 weeks post germination so I reapply 4 weeks after seeding.
Meso is safe 4 weeks after germinaton so I apply that 6 weeks after seeding.
I usually don't have a long fall so I don't bother with Prodiamine but if you do, that is 2 months post germination.
I do use Prodiamine in the spring though.

Seeding, meso, etho.
4 weeks post seeding, etho
6 weeks post seeding, meso
8 weeks post seeding, Prodiamine if needed.
Spring, Prodiamine before poa germinates.

this timing of products is only for fescue.

If you're seeding in the Fall, best results will be had in CT (NC?) if you Aerate/Overseed or Slice Seed during the last week of August or the first week of September. This will give you 8 weeks of excellent growing weather with NO Crabgrass competition and very minimal weed competition. Remember, you'll need 10-30 days for seed germination (depending upon which seed you select) and an additional 21-30 days to grow those blades to be thick and healthy. If seeding during this time, Substitute a Starter Fertilizer (18-24-12) on the August 19th date and reapply it at 3 week intervals until the lawn is full and thick. Once you've reached that point, you can apply a Winterizer (21-3-21) to finish off your season.

~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~

this timing of products is only for fescue.

  • Day of seeding Tenacity + Ethofumesate (No Surfactant)
  • 4 weeks after day of seeding Tenacity + Ethofumesate (No Surfactant)
  • 60 Days after germination use Prodiamine
  • Then in the Spring use Dithiopyr as your PreM

this timing of products is only for fescue.

PreM options for POA A while overseeding?
