The soil that supports our lawns, sports fields, golf courses, and other land uses begins to recharge (store) with water as the evapotranspiration rate drops off during autumn and continues to decline to a very low rate during winter. Water storage in soil is good since that provides the water needed to support green-up and […]

Spring Green-up
Rain late last week combined with rising soil temperatures has initiated green-up of some cool-season grasses in central New Jersey. Soil temperatures have been slowing increasing over the last few weeks. Currently, the 24-hour and 5-day rolling averages for soil temperature are 47 degrees F at Hort Farm 2 in North Brunswick, New Jersey. Keep […]

Mild winter, what does it mean for overseeding of turf or dormant seeding?
Typically, turf management isn’t on top of the to-do list in mid-February. But winter in New Jersey isn’t typical typical this year. The statewide average temperature in January 2023 was 41.0°, which was 9.3° above the 1991–2020 normal and ties with 1932 as the mildest January since records commenced in 1895. For more details on […]

Tropical Storm Brings Rain But What About Gray Leaf Spot?
The passing of tropical storm, Fay brought some needed precipitation to the region, albeit too much at once in many places. Relatively dry soils (assumes not being over-irrigated) and the long, warm days of summer should allow turfs to dry out reasonably fast. But what about gray leaf spot? Spores of the pathogen are thought […]

Green-up Started
Soil temperatures have been warming and reached the mid-40s °F last week at Rutgers Hort Farm No. 2 in North Brunswick NJ and are creeping into the upper-40s °F early this week. Dr. Clarke recommends that treatment of turf with a history of take-all patch be initiated when soil temperature averages 40 to 60 °F. […]

Summer Aeration/Cultivation/Venting
Aeration during the summer can be a helpful practice but does need some caution. Many turf managers performing mid-season aeration on putting greens will be using needle tines, which are less disruptive. But the key words are “less disruptive”; as reminder, needle time aeration (venting) will cause some damage to the roots. How extensive the […]
