Root Rot on scindapsus treubii
What's Happening
Scindapsus treubii is notoriously slow to establish and highly sensitive to waterlogged substrates. The primary vector for rot is the water-to-soil transition after propagation, where water roots fail to adapt to low-oxygen soil. Secondary vectors include physical trauma (falls) that breaks the vascular connection at the stem-root junction, and warm, stagnant propagation water (>24°C) which promotes bacterial bloom.
How to Fix It
- 1
Confirm rot by texture: if roots are black but FIRM, it is normal tannin pigmentation. If they slough off with a gentle pull, it is rot.
- 2
Trim all rotted roots and stem sections. Soak the remaining healthy nodes in a 3% hydrogen peroxide solution (1 part H2O2 to 4 parts water) for 10 minutes.
- 3
Allow the cutting/plant to air-dry (callus) for 2-4 hours before placing in a new medium.
- 4
Instead of straight water propagation, use moist perlite or LECA to provide higher oxygen to developing roots.
- 5
When transitioning to soil, use a 70% inorganic mix (bark/pumice/perlite) and keep humidity at 80% to reduce root load.
How to Prevent It
Never move a Scindapsus treubii cutting to soil until roots are at least 3 inches long and have secondary branches. Maintain propagation water below 22°C using a cool, dark glass jar. Secure vines to prevent 'fall trauma' which causes localized junction rot.
