Temperature and humidity level for Christmas cactus

You can add more humidity to your home with a humidifier or you can put some pebbles and water in a tray and then place the tray on top (make sure the water level is below the top of the pebbles). The pot will be placed on top of the stones and the water in the tray will evaporate and create moisture around the plant. You can too Mist the plant lightly Sometimes to add more moisture.

  3. Allow the ends to dry for 4-5 days until a hard substance forms over the cut area.
  4. Push the dried ends into the soil about 1 inch deep, using 3-5 stems per pot.
  5. In about two weeks, your roots will develop but you want to keep them well watered while they are rooting and you can place a plastic bag over them to increase the humidity until the roots take hold.

Encourage your Christmas cactus to bloom

If you want to keep your Christmas cactus and encourage it to bloom next holiday season, you’ll need to give it some extra care throughout the year:

  • In mid-October, stop fertilizing and stop watering the plant until the shoots appear.
  • Keep your aloe vera in an area with a temperature between 50 and 60 degrees Fahrenheit.
  • Limit the hours of light your cactus receives for the next 6-8 weeks, as it needs about 13 hours of uninterrupted darkness each night (you can place a black cloth over it or put it in a closet). If your room is warmer than 60 degrees, try giving it a few extra hours of darkness each day to compensate for the warmer conditions.
  • Once the flower buds are fully formed, move the plant to an area with bright, indirect light and wait for the buds to fully open (you won’t need to give it 13 hours of darkness at this point anymore). Make sure to continue watering the plant once it has flowered as it may drop its buds if it becomes too dry.
  • If you find that your cactus buds are falling off the first winter, try again as it may bloom the following year.
