Each year I place my ungerminated pots of seeds into the fridge,in about June, at normal fridge

?temperature. A fridge kept in the barn. Each year I get seeds germinating near the

?end of their fourth month in there, with no change of temperature.

Yes, it could be night time temperatures. I've kept a lot of notes over the

years but I've not kept a list of daily highs and lows.   This past spring

was earlier but longer than usual. The first day that I checked the pots was

March 7. Several pots had sprouts. So I don't have a definitive starting

date. Most years, I haunt the pots for days before I see the first sprout.


would have been a  great opportunity.

I started keeping a high/low temperature log this past Dec.   If I can

remember to continue it through this fall, and if I have fall sprouts, I might


able to answer those questions. Iris season tends to distract this type of

record keeping.
