Root Rot Soil Requirements on snake plant
What's Happening
Standard potting soil retains too much moisture for Sansevieria's drought-adapted rhizomatous roots. The fine peat particles compact over 2-3 months, creating anaerobic zones even with careful watering. Succulents require rapid drainage and air pockets to maintain root oxygen levels above the 2mg/L threshold required for healthy metabolic function.
How to Fix It
- 1
Base mix: 50% high-quality potting soil (provides organic matter and nutrients)
- 2
Drainage amendment: 30% perlite or pumice (creates air pockets, improves drainage)
- 3
Structural component: 20% orchid bark or coarse sand (maintains soil structure, prevents compaction)
- 4
Optional: Add 10% activated charcoal to absorb excess moisture and prevent bacterial growth
- 5
Test drainage: Water should exit drainage holes within 30 seconds; if not, add more perlite
How to Prevent It
Refresh soil mix every 12-18 months as organic components break down. Use unglazed terracotta pots which wick moisture through porous walls. Bottom-water only when necessary to control soil saturation levels.
