Poinsettias are the gorgeous, but sometimes sensitive, darlings of Christmas flowers. They do best when they're kept at a stable temperature, so display them away from spots in the home where it's draughty or near sources of heat like radiators and working fireplaces.
Poinsettias also like moist soil, so give it a drink when the surface is dry. If left to dry out completely, they will quickly wilt and leaves may start to turn yellow or brown.
Handle them with care, as knocks and bumps can cause them to go in to shock and drop their exquisite flowers. Displaying them on a surface like a table or sideboard is ideal so they're away from potentially boisterous pets and children.
