how big can a christmas cactus get

Christmas cacti are generally considered to be small plants, typically growing to a height of 1-2 feet. However, with proper care and maintenance, it's possible for a Christmas cactus to grow much larger, reaching heights of up to 5 feet or more. Additionally, some species of Christmas cacti are known to have a much higher growth rate than others, so it's important to research the specific variety you have in order to know how large it can potentially get.
