In my experience no. Could easily be in June before you see any switchIn SE Iowa would frost seeded switchgrass already have germinated this spring? Back in February i frost seeded cave in rock and one other (cannot recall but maybe kanlow) into bean stubble. I sprayed roundup about 3-4 weeks ago and i dont see any signs of anything coming. Wondering if it is still too early or if it was already popping up and i killed it. Doesn’t seem like it has been warm enough but a buddy thinks his is starting to show.
