Carbonation problems

I recently had 15 gallons sitting in my garage. They were in ~45-50 degree weather for 2-4 weeks. The fermometer never read below 52. One batch has no carbonation at all (4 weeks) and the other two have minimal carbonation (2 weeks). The 4 week is a double brown (6.5 abv)and the other 2 are saisons (8 abv).

When bottling the saisons, I pulled yeast from the sediment but did not do this for the brown. I have tried agitating some of the saisons to see if they get a bit more carbonation. Were these beers held too cold and most of the yeast settled out? Is there any steps I can take other than opening each bottle and adding yeast?

Oh and before anyone asks, Yes. Sugar was added and stirred into the bottling bucket.

Addendum: Ignore the saisons. I think my friends were just keeping their beer too cold. I am still wondering about the brown though.

Did you just stir sugar in or did you desolve it in boiling water first? How long have they been in the bottle? I would move them all to a warm place and turn them upside down and right side up for a week then check them.

THe sugar was boiled. I think my partners just kept their bottled beers too cold and didn’t wait long enough. Mine seem to be carbonating fine just taking a bit longer than usual thanks to the cold temps they were stored at. They have been in the bottle 3 weeks
