POA Trivialis in 2 month old sod????
I installed KBG sod a little over two months ago. I ended up getting a hybrid KBG/fescue mix. I have been arguing with the sod supplier that what they gave me was not 100 percent KBG. At any rate, I think I have POA Trivialis coming up on the side only where it is more shadey and wet then the other parts of my yard. We have received more rain this summer than usual. I only try to water once a week at 1 inch. Is this something that was existing I. The soil or came from the supplier? Can someone ID the pics I have posted as rough bluegrass. If it is rough bluegrass can I use a combination of a premergent with post emergent. I have mixed tenacity with prodiamine for my back yard with great success. Is it too soon for a premergent on two month old sod? Thanks for all the help.
