Perlite Propagation on propagation
What's Happening
Perlite propagation provides exceptional aeration and drainage while maintaining consistent moisture at the cutting interface. The expanded volcanic glass particles create 40-60% air pore space, preventing anaerobic conditions that cause rot in succulent and semi-succulent species. Perlite's neutral pH and sterility eliminate pathogen contamination risks.
How to Fix It
- 1
Fill container with coarse perlite (grade 3-6mm) to 2 inches below rim
- 2
Moisten perlite thoroughly; excess water should drain freely through bottom holes
- 3
Insert cutting 1-2 inches deep; support with additional perlite around base
- 4
Maintain humidity by covering with clear plastic dome or bag with ventilation holes
- 5
Bottom-water when top inch becomes dry; roots develop in 3-8 weeks
How to Prevent It
Use perlite alone for species prone to rot; do not mix with soil for propagation phase. Transplant once roots reach 2+ inches.
