Frost seeding works for me.
I like to frost seed small foodplots or plots that are hard to get my tractor on.This should be thought of the fall before you are going to frost seed.I like to use round up in mid fall (middle of OCT. in these parts) and it is also a good time to add lime.It will take over 6 Mo. for lime to get into untilled soil.I like to frost seed in late April early May when there is little chance of snow but the ground still freezes at night.Causing the ground to heave and crack and suck the little seeds into the ground.
frost seeding on a spring snow is a great way to be able to tell exactly where the seed has been applied. No way would I frost seed onto anything more than an inch or two of snow hoping that the snow would melt the same day I seeded.
