Answer for I am going to frost seed in late Feb. early March. Should I spray fields with Plot Start now? Put it down when I frost seed or put it down when the seedlings first emerge?

Apply before you frost seed. A week, day, or month before, the time does not matter just as long as the PlotStart gets into the soil. Do not spray PlotStart on actively growing plants. Spray PlotStart before frost seeding, broadcast the seed, after germination give the species a boost in spring with PlotBoost. This will increase nutrient uptake, reduce water consumption, and make the plot more attractive to deer.
