On top of these, three other tracks are offered along with a pesticide recertification track. Go to http://mogic.org for all of the details and to register.
Fast Fall Towards Winter
As warm as September 2019 was, the bottom certainly dropped out quickly in October. The statewide average was 53.7 F or 3.3 degrees below average. This made October 2019 the coldest since 2009 (which was the 4th coldest on record). The first freeze event occurred for much of the state on October 12, when temperatures dipped into the upper 20's/low 30's for much of the reason. This is a few days earlier than average for northern Missouri and 7-10 days earlier for much mid Missouri and the Ozarks (see the MO Frost/Freeze Guide to dive head first into the numbers). The second temperature dive occurred on Halloween, when a rare October snow event (for much of Missouri) also hit the region. Two - four inches fell in some areas, but most saw it as short-term gray hair on top of the pumpkin. For the record, the earliest measured snowfall (0.1 inches) is October 17 - 23 in Missouri urban areas, all occurring in the late 1800s/early 1900s.
The thermometer needle has been pointing down for most of November, and, as shown above, the forecast indicates it will continue that way. Freezing temperatures are expected this evening and, after a short respite this weekend, look to dive considerably early next week. If Monday's low temperatures are really in the low teens and the high doesn't rise above freezing, the end of the season will be here awfully early. Irrigation systems are being blown out across the area, and the last mow and spray of the year may have occurred or will this weekend. In recent years fall seemed to persist until Thanksgiving. In 2019, September was 6+ degrees above normal and October was 3+ degrees below normal. With the end seeming nigh, one might ask if we even had a fall season?
Over the last two weeks, precipitation relaxed for KC and the NW part of the state but cranked up for mid MO, and especially southern MO. Precipitation, the early snowfall and cool temperatures have resulted in unusually wet soil conditions for much of the state. Unfortunately, an elevated risk for flooding is on again for the state since the water has no evapotranspiration escape route. The silver lining may be a reduced risk for winter desiccation for most turfgrasses, but as we learned last season zoysia doesn't respond well to cold and wet conditions.
Dry & Cold Expected
Soil temperatures, which can be viewed here, are plummeting quickly. As the growing season starts to head out of bounds, I often get asked about hitting turfgrass with late management practices and if they will gain yardage or draw a penalty flag. While many of these answers aren't set in stone by research, I've accumulated some of my responses and what the research indicates.
What to do about late large patch?
