Q.Does vegetation killer work in winter
I would like to kill the vegetation in my volleyball court; would it work now to stop spring growth?

It depends on the type of vegetation and if it is actively growing now or not, the type of weed killer and the temperature. In any case it's not the best time for herbicide application. Generally temperatures should be above 50 degrees F (10 C).
When temps warm up a bit, use can use a glyphosate product that will be absorbed through green foliage and translocated throughout the plant tissues, including roots for a complete kill. If it is larger woody vines and shrubs then another product choice will be better such as a bush killer.
