The Boobie Cactus, scientifically known as Myrtillocactus geometrizans ‘Fukurokuju,’ is a cultivar recognized for its unique, undulating, and monstrous growth habit. This plant’s distinctive form, which resembles a cluster of rounded mounds, makes it a desirable addition to any succulent collection. Reproducing this unusual cactus requires a precise, multi-step approach focused on cuttings to ensure the new plant retains the desired characteristics. Successful propagation involves careful preparation and a patient rooting process.
Selecting the Best Propagation Strategy
Propagating the Boobie Cactus relies exclusively on taking cuttings, which are small offsets or pups removed from the parent plant. This method is necessary because the ‘Fukurokuju’ form is a genetic mutation, specifically a monstrose cultivar. If grown from seed, the resulting plants will revert to the standard columnar form of Myrtillocactus geometrizans.
Taking a cutting ensures the new plant is a genetic clone of the mother, preserving the unusual growth pattern. This technique is the best way to reproduce the specialized ‘boobie’ form. Cuttings should be taken during the active growing period, typically spring and summer, when warmth encourages faster rooting.
Preparing and Curing the Cuttings
Once a healthy pup or segment has been selected, a clean cut must be made using a sterilized, sharp knife or blade to minimize the risk of introducing pathogens. Sterilizing the tool with rubbing alcohol prevents bacterial or fungal infection at the wound site.
Immediately following the cut is the curing, or callousing, period, which prevents the cutting from rotting. Cacti are prone to rot if planted immediately because the open wound absorbs too much moisture. The cutting must be placed in a dry, warm location with indirect light and good air circulation. The cut surface will dry and develop a hard, protective layer. This process can take anywhere from a few days to several weeks, depending on the cutting’s size and ambient humidity. A white, hard, and dry scab indicates the cutting is ready for planting.
Establishing the Cutting in Substrate
After the callus has fully formed, the cutting is ready to be placed into a rooting medium. The substrate must be well-draining to prevent water retention around the root zone. A specialized cactus or succulent potting mix is appropriate, but it should be heavily amended with inorganic materials such as perlite, pumice, or coarse sand to enhance drainage and aeration.
Small, shallow containers with drainage holes are preferred, and terracotta is a good material because its porous nature allows moisture to evaporate quickly. The calloused end of the cutting should be set just barely on the surface of the dry substrate. Tall or heavy cuttings often need temporary support, like small stones or stakes, to keep them upright and stable until new roots anchor the plant. Only enough contact with the substrate is necessary for root formation.
Encouraging Successful Rooting
Care immediately after planting focuses on stimulating root growth while managing the environment. The newly planted cutting requires bright light but must be protected from harsh, direct sunlight, which can cause scorching. A location near a south-facing window with a sheer curtain or a bright, sheltered outdoor area is ideal. Warm temperatures, ideally above 65°F (18°C), aid the rooting process.
The watering protocol is important; the substrate must remain completely dry for the initial weeks to avoid rot. Since the cutting has no functional roots yet, it cannot absorb water from the soil. After a few weeks, or when new growth is observed, you can begin to lightly mist the surface or water sparingly, ensuring the soil dries out rapidly between applications. Rooting is confirmed when the cutting resists a gentle tug, indicating roots have taken hold. This process can take several weeks or even months.
