Frost in the ground

[MossRoad]

In a couple of weeks I have to dig a small footing for an addition.

There is a 3 -5 inches of frost in the ground right now...

I know if you cover the ground with hay it would cut down on the ground freezing but the ground is already frozen.

My question is if I put hay down now on the ground and keep it there until I start the job...Would the frost in the ground be reduced or just stay the same?

The temp in the area ranges from the teens to 30's and this area getting little sun.

Thanks

Where are you lacated? Someone in your region may have some experience to share.

In a few weeks, even with insulation, the ground may still freeze.
