When should I frost seed?
Should I frost seed when snow is still on the ground or wait until the snow has melted?
Depends on several factors, IMO. How deep is the snow? Crusted over? If there’s just a little bit of it, and you have some melting days coming, I’d say go for it. If you will have quite a bit of runoff from the melting, I’d say wait so you don’t lose as much seed from snowmelt washing it away.
Te snow is about 8/10" deep. Some warm days are coming the next several days. (40/60*) could get run-off. So, based on coming warm weather should I wait until the snow is gone?
Here in mid Michigan I am planning on frost seeding clover and some switchgrass this week. Still some crusted snow in spots but with 10-14 days of daytime temps in the 40s and nights in the 20s it’s a perfect time.
c5ken.....I’d suggest waiting until the snow is gone, then. You will most likely still get plenty of freeze/thaw cycles to help work your seed into the soil, plus you won’t chance losing much seed to runoff.
For the reasons mentioned above, I think it is a best practice to wait until the snow is melted.
As a general rule, you want a minimum of 5-6 days where the temps go above freezing in the day and then below freezing at night to get good soil to seed contact.
I believe it is best to frost seed early in the morning when the ground is still frozen. If you wait till later in the day, the ground can become muddy. That mud will build up on your shoes, and you will be amazed at all the seed that sticks to your muddy shoes.
