Q.Potted Bougainvillea On Deck, Will Be Getting Cold Soon Needs Heavy Pruning To Fit In House
I am not sure where to prune plant and how much. It is still blooming and has buds. Thank you
Generally, trim to keep the form that you wish it to have or if it has grown "too much" for your indoor winter location. Usually, that does not mean major pruning. If you are happy with the way it looks and it is not too big for the inside of your home, just leave it alone too.
