New potted hydrangea keeps wilting
I used to have hydrangeas in the garden when I lived in an apartment, but the drunken apartment manager mowed them down until there was one one left. It's outside now and I am hoping it will make a comeback from winter.
Meanwhile, I bought a new hydrangea in a pot. It is still too cold to put it outside here in central New York State, so I have been keeping it moist and in the sun, but some nights it gets pretty cold by the windows. The first time it happened, the soil was still moist, but it didn't perk up until I watered it again, though I was nervous I was watering it too much. I also moved it further into the room, away from the cold windows. But now I have been around in circles 3 or 4 times -- wilts, revives with water and away from cold, wilts again, etc. So I just left it away from the windows, and did not water it again (it was plenty moist already) -- and darned if it didn't wilt on me again.
So, I watered it -- with great trepidation -- and moved it completely in the other room where it will get some morning sun but be warm and away from any cold.
It's going to be another couple weeks before it is sure to not drop below freezing overnight -- what SHOULD I be doing to keep this plant healthy until then?
P.S. When the blooms wilt, am I supposed to CUT them off? What's the best way to go about that? With my outdoor ones, I just left them alone and they were happy -- until that jerk mowed them down.
