Weedy grasses lurking in lawns

This time of year, weedy grasses such as annual bluegrass and rough bluegrass can hang out in lawns, landscapes, and golf courses, barely detected. However, once summer stress kicks in, these grasses decline faster than the surrounding turf leading to brown “patches” that may be mistaken for diseases. Even in spring, the off-color of these . . . → Read More: Weedy grasses lurking in lawns

Large patch in zoysia

It’s been pretty dry lately, (and what’s up with these 90+ temps???) but the forecast calls for cooler temps this weekend with chances of rain in some areas. Those conditions could cause mild large patch symptoms to flare up.
