Q.Bougainvillea spring care.
We kept a Bouganvillea indoors in winter and let it go dormant. However after awhile it started to grow green again and we gave it water and some sun.
Now we have a large green tree in our living room and want to put it outdoors to start blooming.
What steps should we take to prepare to locate the plant outdoors and to get it to start blooming?

I don't know your growing zone, so just make sure your night temperatures are above 40 degrees F.
Give your plant some shelter from wind and sun for the first days and weeks.
Hardening off is the best way to re introduce your plant to the outdoors.
Make sure you check watering daily.
