Force Hydrangeas to go dormant?
Is there a way to force the hydrangeas in the pots to go dormant? With the exception of one, all the potted ones are still green and have lots of leaves on them. I'm concerned this will effect them for next Spring and I won't have any blooms?
Temps are in the low 30's this week and I have brought them all inside. They are in a room that gets sun and of course has the house temps which is kept between 68-72 degrees. Should I move them to garage where it is colder but doesn't get any sunlight? Also, the vent to the clothes dryer goes into the garage, will the hot air effect them in a bad way?
As always thanks for all the help!
