|Rough(stalk) bluegrass (Poa trivialis) will turn purple or|
red when it becomes heat-and/or drought-stressed,
and then brown when completely dormant.
|Rough bluegrass turns brown when completely dormant.|
While it looks dead, it will revive itself when cooler
weather returns in the fall.
|While it may appear to be dead, dormant Poa triv|
will come back from live stolons on the soil surface. You
can find these green stolons when you dig down into
the patches of dormant, brown grass.
|This happy, green Poa triv is growing in a shady spot|
just a few feet away from the brown patch pictured
above. It is aggressively and successfully crowding out
the original grass - turf-type tall fescue.
I’m hoping for some cooler, wetter weather that will give us healthy, GREEN grass again.
