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 […]

Plant growth regulators can be used to suppress seedhead production if applications are properly timed. Much like pre-emergence herbicides that are not effective if applied after weed emergence, PGRs are less effective if applied too late. […]
