Christmas Cactus Propagation Debate: Humidity Is the Key Variable

Why Experiences Differ

Schlumbergera roots easily in humid climates/greenhouses. In arid zones (Phoenix), low humidity desiccates cuttings before rooting. Your moist-soil method works where ambient humidity >40%.

Universal Tips

• Callus 2–3 days only.
• Use clear dome/bag for humidity.
• Bottom heat (70°F) speeds rooting.
• Peat-perlite mix, not pure sand.

Desert Christmas Cactus Alternative

Cylindropuntia leptocaulis roots like typical cactus—easy in dry air.
