Answer: It may be fine or it may not, I'm sorry I can't tell you more precisely. It is possible that the seeds began to sprout and were killed by heaving, or they may have rotted due to the cold and dampness, or it is possible they may still germinate when the soil and weather warm up. Grass seed needs a minimum soil temperature of about 50 degrees to germinate, and depending on what kind of grass you planted, air temperatures between about 60 and 80 degrees. You might want to check with your county extension and see how they feel about it since they will be more familiar with the weather and soil temperatures in your area in the time since the seed was spread. Good luck with your lawn!
