Should I start wintering my flowers?

A:

Winterizing for flowers usually starts end of September to mid October. The weather forecast shows no freezing weather until mid November. If we keep getting warm days, flowers will continue to grow and not harden off. Best to wait until the warm weather shifts to cooler weather - when?  
Time will tell.
