Hey no worries that's what we're here for!
Frost seeding is basically a non-traditional way of seeding an area without the use of the traditional equipment. For us in the north, you basically wait till the time in the spring when you get that freeze and thaw thing going on...Usually when the snow is off before it starts to warm up. From what I understand this will only work well with seed that just requires just the minimal amount of soil to seed contact (clovers work well, etc...I don't believe it would work very well with corn, oats, and any other seed that needs to be planted an inch or two down). Basically, you spread it on the ground where you want to seed (usually a plot that is already there, but I've heard you can do it on a new plot as well, but it may not produce as well since sometimes it needs that traditional equipment to get started). By the motion of the ground freezing and thawing, it opens up holes and cracks in the soil where the seed falls into, and from there grows your seed! Like I said, it's not the best way to seed but it works especially if you want to overseed an older plot!
Let me know if you have any other questions, or if this doesn't make sense!
