Christmas cacti gets its name because it blooms around the month of December, during the holiday season. Even though they only bloom during the holiday season, the plant needs to be taken care of throughout the year. This includes watering the the cactus periodically and keeping it in indirect light. Christmas cacti like night temperatures to be cool and day temperatures to be around 70 degrees. Christmas cacti feature flat leaves with round teeth and bright pink to purple flowers. Help out the blooming process with a bit of caster oil.
Keep your Christmas cactus inside at room temperature and allow it to get partial sun during spring, summer and fall.
Take the plant out of any bright light in the evening to help it come into bloom.
Add one to two tablespoons of caster oil to your plant's soil in late September or early October. You want the caster oil to penetrate the soil and get as close to the roots as possible. This will help the cactus produce more blooms later in the year.
