Over the past 7 to 10 days, warm-season weeds have really turned the corner and are growing rapidly. It’s probably no coincidence that 5-day average soil temperatures finally pushed past 70 degrees about 10 days ago in central NJ. Until last week, most of the crabgrass I observed was growing slowly with a chlorotic appearance. […]

Weeds off to a Slow Start
Despite a quick start to the spring, soil temperatures remain low across the much of the state. Average soil temperatures (3-inch depth) have been hanging around the mid 60s in central NJ and many warm-season weeds such as crabgrass have hardly developed despite germinating over 6 weeks ago. This crabgrass at our research facility has not […]

Hurry Up and Wait. Now Go!
At the beginning of March we were potentially a week or two away from annual bluegrass seedhead emergence thanks to an extremely warm February. Cooler temperatures prevailed and significant snowfall across much of the Northeast brought soil temperatures down and put the brakes on annual bluegrass development for a few weeks. It’s now the beginning of […]
