I admit it. I put off putting my VFT into dormancy until mid-December. The dates I hear about is from Thanksgiving through Valentine's day; but I'm guessing some folks cheat.
I'll try Valentine's day for when I break out my stuff from the cold room (It didn't really get that cold, it's been a mild winter), and back into the house. The plant sure looks like it went dormant, but I'll just have to find out if it worked out correctly.
If not, I'll be going back to the store and buying another one.
Please share your tales. Later!
