Temperatures at my place sometimes fall to 32F but mostly remains around 45-50F.
How should i take care of my potted hydrangea in winter?
depending on the variety, heres what you should do. they are pretty self sufficient, so just leave it alone. they tend to get leggy and the leaves will get spotty, but thats normal. is it a big daddy, or a endless summer. those varieties bloom on new wood so you can clip them when there is no longer a threat of freeze others bloom on old wood so you can clip now, preferably sooner.
