Propagation on aloe vera
What's Happening
Aloe vera propagation fails when attempting to root leaf cuttings in water. Unlike many succulents, Aloe's thick, fleshy leaves release sugars and nutrients into water, creating ideal conditions for anaerobic bacterial growth (Pythium, Erwinia) that causes soft rot. Additionally, large cuttings with uncalloused wounds are vulnerable to basal rot when planted immediately. Successful propagation requires proper technique: using offsets/pups rather than leaves, allowing complete callus formation, and employing soil-based rooting.
How to Fix It
- 1
Select propagation material: Choose 2-3 inch pups/offsets from healthy mother plant base
- 2
Prepare cuttings: Remove pups with clean razor, trim any damaged sections
- 3
Callus formation: Lay cuttings on dry paper towel in shade for 48-72 hours until cut seals
- 4
Plant in dry mix: Use fresh succulent soil with 50% perlite; bury only 1/3 of cutting
- 5
Rooting care: Water sparingly after 1-2 weeks; roots emerge in 4-8 weeks; resist checking frequently
- 6
Avoid water propagation: Soil or perlite rooting prevents bacterial rot in cut tissue
How to Prevent It
Propagate using offsets/pups from healthy mother plants only. Select 2-3 inch pups with established root primordia. Allow all cut surfaces to callus 48-72 hours before planting. Use perlite or coarse sand rooting medium instead of water. Maintain 65-75°F with bright indirect light during rooting phase.
