Filling holes after form ties in concrete despite cold weather?

[danne888]

I have cast a wall for our greenhouse using form ties for the mold, resulting in holes from the cones. Currently setting up the greenhouse and would then like to continue with building beds afterwards. However, it's getting quite cold at night, down to freezing, and we've already had the first frost. Hence, I assume it's difficult to use concrete filler.

Does anyone have a tip on how I can proceed to fill this despite cold weather? Or is it a matter of waiting until spring?

See image below, thanks in advance

Putty on, there are no freezing temperatures coming and it's just small holes.

Thank you! Very good news, then I'll go ahead. Should I use primer before I use lagningsbruk?
