Propagating Boobie Cactus

You can propagate the boobie cactus in multiple ways. Here are some of the best.

From Offsets

  • Boob cactus produces offsets or “pups” – that can be removed and replanted to grow into new plants.
  • Choose a well-draining pot and fill it with a cactus or succulent potting mix.
  • Carefully remove the offsets and dry them for a few days to prevent rotting.
  • Once the offsets have callused over, plant them in the prepared potting mix. Make sure to plant them deep enough so that they are stable and won’t fall over.

From Cuttings

  • Choose a healthy, mature boobie cactus plant and use a clean, sharp knife to take a cutting. Make sure the cutting is at least 3-4 inches long and has several spines – now let it dry.
  • Plant the cutting in a well-draining cactus or succulent soil mix, burying it about an inch deep, and water them sparingly.
  • It can take several weeks for the cutting to form roots. Once the roots have formed, you can begin to water them more regularly.

Boobie cactus propagation can also be done with seeds. It’s essential to obtain seeds from a reliable source or your own healthy booby cactus.

Next, prepare a well-draining potting mix suitable for cacti by combining equal parts of sterile sand, perlite, and cactus potting soil. Moisten the mix slightly to make it slightly damp but not overly wet. Fill small seed trays or pots with this mix, leaving a small gap at the top for watering.

Sprinkle boobie cactus seeds evenly on the soil surface without burying them. Lightly press for good contact. Cover the tray with a clear plastic dome or bag for humidity and place it in a warm, bright spot away from direct sunlight. The seedlings will emerge in a few weeks.

If you’re growing your boobie cactus indoors, place it near a south-facing window that gets plenty of sunlight throughout the day. If you’re growing it outdoors, make sure it’s in a spot that gets partial shade during the hottest part of the day.


Use a well-draining cactus potting mix for boobie cactus. It should consist of a blend of sandy soil, perlite, and cactus-specific potting soil.

This type of soil allows excess water to drain away, preventing root rot.

2. How Often Should to Repot Boobie Cactus?
