Sowing prairie seed into snow
I am interested if anybody has experience with prairie seed sown on top of snow. This year I seeded a one acre expansion to my existing prairie plantings and part of it was done late on top of snow. The area has a south facing aspect with modest slope. It was prepared by chemical treatments and burning (no tilling). Seeding was done by hand after mixing seed with sawdust.
One half of this field was seeded onto the first accumulated snow of the season (about 3/4" of dry snow). This seeding was covered the next day by a big blizzard (about a foot of snow followed by several inches freezing rain).
The other 1/2 of the field was sown durig a warm spell in late December onto a wet melting layer of snow. Under this was a thick compacted layer layer of snow/ice.
I have had good results with late fall seedings onto bare ground. I live in Wisconsin and did not plan to seed on snow, unfortunatly winter came early. I will say that seeding on snow really lets you get a good distribution as the sawdust really stands out. It will be interesting to see if there are any differences in establishment between the two different seeding dates.
