The Boobie Cactus, Myrtillocactus geometrizans ‘Fukurokuryuzinboku’, is a unique cultivar. Its distinctive, rounded protrusions give it its common name and make it a popular ornamental plant. Propagating this cactus from an existing plant is a popular method to create new specimens, especially since propagation from seeds does not produce true-to-type plants.
Preparing for Boobie Cactus Propagation
Select a healthy, mature stem from your mother plant, aiming for a cutting approximately 4 to 6 inches long. Gather clean, sharp, sterile cutting tools, such as a knife or pruning shears, to prevent disease. You will also need well-draining cactus or succulent potting mix and appropriately sized pots with drainage holes. Wearing gloves is advisable to protect your hands from the cactus’s spines.
Step-by-Step Boobie Cactus Propagation
Make a clean cut from the selected stem segment. Allow the cutting to callous over by letting the cut end dry and form a hard, protective layer, which prevents rot once planted. Place the cutting in a warm, dry location with indirect sunlight for a few days to a couple of weeks, until a firm, white callus has developed.
Fill your pot with a well-draining cactus mix. Create a small hole in the center of the soil and gently insert the calloused end of the cutting about an inch deep. Ensure the cutting is stable and upright, providing support if necessary, and avoid burying too much of the stem.
Aftercare for New Cuttings
Place the potted cutting in a warm location that receives bright, indirect light, as young cuttings are sensitive to intense direct sun, which can cause scorching. Temperatures above 18 degrees Celsius (65 degrees Fahrenheit), ideally between 21 to 27 degrees Celsius (70-80 degrees Fahrenheit), are conducive to rooting.
Water the newly planted cutting sparingly, just enough to moisten the soil around the base. Allow the soil to dry out completely between waterings to prevent rot, as overwatering is a common pitfall. The rooting process can take several weeks to a few months, depending on environmental conditions.
Gently tug on the cutting after a few weeks to check for resistance, indicating that roots have begun to form. Observe for any signs of new growth on the cactus itself, which also signals successful rooting. Once established, the new plant can gradually be introduced to more light and a regular watering schedule.
Troubleshooting Propagation Issues
Rotting is a frequent problem, appearing as soft, mushy, or discolored spots on the cutting. This often results from overwatering or insufficient callousing before planting. If rot is detected, cut above the affected area, allow the healthy portion to re-callous, and attempt propagation again in drier conditions.
Failure of cuttings to root can occur if temperatures are too cool or if the cutting remains too wet. Ensuring consistent warmth and allowing the cutting to thoroughly dry and callous before planting can prevent this. Pests like mealybugs or scale can also infest new cuttings, appearing as small, cottony masses or bumps on the plant. Prompt treatment with insecticidal soap or neem oil can help manage these infestations.
