Moon Cactus Grafting

Moon cactus, also known as gymnocalycium mihanovichii, is a popular cactus species that lacks chlorophyll and therefore cannot produce its own food through photosynthesis.

As a result, it needs to be grafted onto another cactus to survive. Here are the steps for moon cactus grafting:

Required Materials:
  • A healthy, established rootstock cactus, preferably with a stem diameter similar to that of the moon cactus you want to graft.
  • A sharp knife or blade
  • Moon cactus (scion)
  • Rubber bands or grafting tape
  • Sterilizing solution (such as rubbing alcohol or hydrogen peroxide)
  • Optional: rooting hormone powder or liquid

Steps For Moon Cactus Grafting

  1. Choose a healthy rootstock cactus that is about the same size or slightly larger in diameter than the moon cactus you want to graft. The rootstock cactus should be healthy, with no signs of disease or damage.
  2. Sterilize your knife or blade with the sterilizing solution to prevent infection.
  3. Cut off the top of the rootstock cactus, leaving a flat, even surface for the moon cactus to sit on. You can also create a groove or indentation on the top of the rootstock cactus to help hold the moon cactus in place.
  4. Sterilize the moon cactus, and then make a diagonal cut at the base of the stem, exposing the inner flesh.
  5. Apply rooting hormone powder or liquid to the cut surface of the moon cactus stem to encourage faster healing and rooting. This is optional but can help speed up the healing process.
  6. Carefully place the moon cactus onto the flat surface of the rootstock cactus, making sure the cut surfaces match up as closely as possible.
  7. Use rubber bands or grafting tape to secure the moon cactus in place, making sure it is tightly wrapped to prevent movement.
  8. Place the newly grafted cactus in a warm, bright location, but out of direct sunlight. The rootstock cactus will provide the moon cactus with nutrients and help it grow.

It is important to note that moon cactus grafting can be challenging, and success rates can vary. Be patient and keep an eye on the graft for several weeks to ensure it takes hold. Once the graft has successfully taken, you can remove the rubber bands or grafting tape.


Grafting a moon cactus is a simple process that involves attaching the colorful cactus onto the rootstock of a green cactus. This allows the moon cactus to get the nutrients it needs to survive. Here is a step-by-step guide for successful grafting:

Materials needed:

  • Moon cactus (scion)
  • Green cactus (rootstock)
  • Sharp knife or blade
  • Rubber bands
  • Alcohol

Step 1: Clean your tools Ensure that all tools, including the knife or blade, are clean and sterilized with alcohol to avoid introducing any infections or diseases to the cacti.

Step 2: Prepare the rootstock Choose a green cactus that is similar in size to your moon cactus scion. Make a clean cut on the top of the rootstock, creating a flat surface where the scion will be placed.

Step 3: Cut the scion Use a sharp knife to cut a clean slice from the bottom of the moon cactus. Ensure that the cut is made at an angle that matches the angle of the rootstock.

Step 4: Attach the scion to the rootstock Carefully place the scion onto the flat surface of the rootstock. Ensure that the angles of the scion and rootstock match. Use a rubber band to hold the scion in place. Wrap the rubber band around the scion and rootstock several times, making sure that it is tight enough to hold the scion in place.

Step 5: Wait for the graft to heal Allow the graft to heal for several days or even weeks. During this time, ensure that the cactus is kept in a warm and dry place, away from direct sunlight.

Step 6: Remove the rubber band Once the graft has healed, remove the rubber band. Over time, the moon cactus will begin to grow and form roots that will attach to the rootstock. At this point, you can care for the cactus as usual.

In conclusion, grafting a moon cactus is an easy and straightforward process. By following these steps, you can successfully graft your moon cactus and enjoy its vibrant colors for years to come.
