How long do the effects of Tenacity last?

Post by northeastlawn » May 5th, 2016, 2:43 pm

We usually have a cookout memorial day weekend, I have started spot spraying my POA at the 2oz rate weekly (did one 4oz marking app, and one 2oz spot spray last week).

Its a mixed PR/KBG lawn, how long does it take for the whitening effect to go away?

I do notice the POA gets really bleached and the other grass is still green, so its working, but I still have bleaching I'd like to be gone by memorial day weekend.

I just want the yard looking good in three weeks, do you think I can get away with one more spot pray app or should I just hold off?

Based on my experience whitening hits its peak at almost 14days... but doesn't really go away fully until dead and rotted. Which is 3-5wks?? I suppose like a week and a half out you could cut a bit lower to remove remaining whiteness?

my neighbors ghost weeds...just sit there.... GO AWAY white weed! lol

Maybe Ill cut it a bit shorter, then let it grow long to cover those areas up. I still have a few weeks for some decent top growth if it ever warms up.

I show off my bleached patches during our annual Memorial Day BBQ. Heck, I even time my spring application for maximum effect during the BBQ. Brown is ugly, but white is fun.
