There is great variability on the present condition of Poa annua on greens throughout much of the state. In many cases patches of poa are a tan or bronzes color. In these areas often there are some plants with new leaf growth but many plants have no green leaf tissue, white crown tissue and a very weak root system (maybe one or two small white roots). Will these plants recover? Or how many will recover? That is the $64 question.

Due to dry conditions going into this Memorial Day weekend and high temperatures predicted WATCH THE TURF YOU ARE MANAGEING VERY CAREFULLY! Often in these situations we get samples to check for diseases and the primary problem is drought damage. We have seen this repeatedly under weather conditions like this and especially over long holiday weekends. It is recommended that you take the time to carefully check turf conditions in the afternoon everyday through this period. Check the soil profile for moisture conditions, do not make assumptions. Keep the turf healthy!

It appears that there is now a second occurrence of Brown Ring Patch / Waitea Patch (Waitea circinata var circinata) on Poa annua in Ohio. The first was during the “hot” period of March when temperatures suddenly approached 80°F / 27°C. Cases were confirmed in NW and Central Ohio. Now there are samples and cases in SW, Northern and Central Ohio. If temperatures cool down and then there is a sudden warm / hot period - symptoms may occur again!

Few ground covers are as versatile, utilitarian or as environmental important as a lawn. Turfgrass has the ability to be maintained by mowing. Mowing is the routine cutting off the ends of the leaves, a partial defoliation of the turfgrass plant, without severely damaging or killing the plant. This is a unique feature of turfgrass plants. Mowing is one of the most important maintenance practices performed in lawn maintenance. Regardless of the type of grass in a lawn or whether the lawn is fertilized, irrigated, an old lawn or a new lawn, proper mowing is essential for a high quality lawn.

Diseases slow - red thread and leaf spots have slowed down considerably with dryer weather. These fungal diseases could easily reoccur with moderate temperatures and moist conditions. If your area is wet… then these and other diseases may be active and increasing.

Yes, it is that time of the year again where people are heading back outside to start work on their yards and turf. One of the first things people notice is a light green matt in areas with thin to no turf cover, our answer, is often that you have moss. Moss appears in areas that are not conducive for turfgrass to grow.
